<p>Quiero agradecer en ese &#x201C;tiempo de tesis&#x201D; a todas las personas que por cercan&#x00ED;a o no han hecho realidad ese sue&#x00F1;o:</p>
<p>En primer lugar, a mis hijos, Emma, In&#x00E8;s y Abel quienes tuvieron que soportar mis horarios de trabajo, los largos momentos donde no pude atenderles c&#x00F3;mo deber&#x00ED;a, mis ausencias y mis saltos de humor. Me han permitido llegar a cumplir hoy un sue&#x00F1;o. Gracias por vuestro amor incondicional y vuestra paciencia. Que esta nueva etapa para mi sea tambi&#x00E9;n una nueva etapa en vuestras vidas.</p>
<p>A mi hermano, Ludovic, quien siempre me ha apoyado a pesar de la distancia geograf&#x00ED;a muy grande. Aunque no estuvieras aqu&#x00ED;, siempre he sentido su apoyo y la felicidad de verme conseguir mis metas. A mi familia en general de sangre y de coraz&#x00F3;n, quienes siempre vieron en mi la capacidad de conseguirlo. A mar&#x00ED;a por su gran paciencia y la ayuda (con los ni&#x00F1;os) que me ha permitido llegar al final.</p>
<p>A mis Padres, que desde el cielo estar&#x00E1;n gozando de mi felicidad. Gracias a ellos, pude ser quien soy en d&#x00ED;a. Me han dado las fuerzas necesarias desde arriba para no abandonar nunca, y bien saben que grande eran las ganas.</p>
<p>A mis Hermanos de parroquia, que con sus oraciones me han permitido seguir adelante y no caer. Dios es grande y lo permite todo para quien tiene fe.</p>
<p><target target-type="page" id="pges_10"/>A mis compa&#x00F1;eros de trabajo en general, y particularmente en Cesar Fernandez de la Pe&#x00F1;as, por quien no hubiera sido nada posible. Gracias por haber creado en m&#x00ED; y permitirme trabajar en lo que m&#x00E1;s me gusta. A mis amigos, por apoyarme cuando m&#x00E1;s lo necesitaba, para echarme una mano en momentos dif&#x00ED;ciles, aunque fuera solo tender el o&#x00ED;do.</p>
<p>Y finalmente a mi director de tesis, Domingo Palacios Ce&#x00F1;a, sin quien hoy no estar&#x00ED;a aqu&#x00ED;. Gracias por haber cre&#x00ED;do en m&#x00ED;, por ense&#x00F1;arme tantas cosas y por servirme de ejemplo Que nuestra colaboraci&#x00F3;n siga y me sigas dando ejemplo. Sin ti nada de esto habr&#x00ED;a sucedido.</p>
<p>De todo mi coraz&#x00F3;n, gracias a todos.</p>

<title><bold>Actividad f&#x00ED;sica: Definici&#x00F3;n y caracter&#x00ED;sticas</bold></title>
<p>La actividad f&#x00ED;sica, es considerada por la Organizaci&#x00F3;n Mundial de la Salud (OMS) como: &#x201C;<italic>cualquier movimiento corporal producido por los m&#x00FA;sculos esquel&#x00E9;ticos y que produce un gasto energ&#x00E9;tico</italic>&#x201D; (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>) y engloba las actividades realizadas jugando, trabajando, de desplazamiento, actividades del hogar o de ocio. Pero el concepto de actividad f&#x00ED;sica (AF) es mucho m&#x00E1;s amplio. Adem&#x00E1;s de una dimensi&#x00F3;n biof&#x00ED;sica del movimiento como especificado en la definici&#x00F3;n de la OMS, existe otras dos dimensiones. Una dimensi&#x00F3;n personal y una dimensi&#x00F3;n sociocultural. La primera est&#x00E1; relacionada con la experiencia que tiene cada persona de la pr&#x00E1;ctica de AF. La segunda dimensi&#x00F3;n est&#x00E1; ligada a la propia pr&#x00E1;ctica f&#x00ED;sica (<xref ref-type="bibr" rid="CIT060">Dev&#x00ED;s Dev&#x00ED;s &#x0026; Peir&#x00F3; Velert, 2001</xref>)</p>
<p>Con estas consideraciones, <xref ref-type="bibr" rid="CIT060">Dev&#x00ED;s Dev&#x00ED;s &#x0026; Peir&#x00F3; Velert (2001)</xref> definen la actividad f&#x00ED;sica como:</p>
<p><italic>&#x201C;Cualquier movimiento corporal intencionado que se realiza con los m&#x00FA;sculos esquel&#x00E9;ticos, resulta en un gasto de energ&#x00ED;a y en una experiencia personal, y nos permite interactuar con los seres y el ambiente que nos rodea.&#x201D; (p.299)</italic></p>
<p>Por lo tanto, se podr&#x00ED;a incorporar como AF, actividades que incluyen andar, correr, nadar, esquiar, pasear o tareas realizadas en el hogar como limpiar, ordenar, etc.</p>
<p>Pero es preciso aclarar, que no se puede confundir la AF con el ejercicio f&#x00ED;sico (EF), ya que este &#x00FA;ltimo es una actividad reglada, estructurada, organizada, repetitiva y con un claro objetivo de mejora o mantenimiento de las capacidades f&#x00ED;sicas del individuo (<xref ref-type="bibr" rid="CIT056">Dasso, 2019</xref>). Por lo tanto, el EF es una subcategor&#x00ED;a de la AF. El objetivo del EF es la mejora de uno o m&#x00E1;s de los componentes de la condici&#x00F3;n f&#x00ED;sica, adem&#x00E1;s el EF es un medio para alcanzar una mejora de la condici&#x00F3;n f&#x00ED;sica.</p>
<p>La condici&#x00F3;n f&#x00ED;sica (CF) est&#x00E1; definida como el conjunto de las capacidades o cualidades f&#x00ED;sicas (como por ejemplo la fuerza, resistencia, flexibilidad y velocidad) de un individuo. El nivel de estado de la CF est&#x00E1; formado por todas las funciones y estructuras que intervienen en la AF. La mejora de la CF se realiza a trav&#x00E9;s del acondicionamiento f&#x00ED;sico, es decir el trabajo de una o varias capacidades f&#x00ED;sicas para la mejora del sistema m&#x00FA;sculo-esquel&#x00E9;tico, sistema cardio-respiratorio, psico-neurol&#x00F3;gica o endocrino (<xref ref-type="bibr" rid="CIT047">Castro-Pi&#x00F1;ero et al., 2010</xref>; <xref ref-type="bibr" rid="CIT169">Rosa-Guillam&#x00F3;n, 2017</xref>; <xref ref-type="bibr" rid="CIT173">Ruiz et al., 2011</xref>). As&#x00ED;, un nivel alto de CF implica tener una respuesta fisiol&#x00F3;gica optima de todas ellas.</p>
<p><target target-type="page" id="pges_16"/><xref ref-type="bibr" rid="CIT033">Bouchard &#x0026; Shephard (1994)</xref>, autores de referencia del estudio sobre la condici&#x00F3;n f&#x00ED;sica y sus factores, presentaron el esquema de los principales componentes de la CF (ver <xref ref-type="fig" rid="c1-fig1">figura 1</xref>).</p>

<p>Las capacidades f&#x00ED;sicas se pueden dividir en 2 categor&#x00ED;as diferentes. Por un lado, las capacidades relacionadas con el rendimiento deportivo y otras relacionadas con la salud. Las capacidades f&#x00ED;sicas relacionada con la salud son definidas por <xref ref-type="bibr" rid="CIT173">Ruiz et al. (2011)</xref> por la capacidad aer&#x00F3;bica, la capacidad m&#x00FA;sculo-esquel&#x00E9;tica, la capacidad motora y la composici&#x00F3;n corporal. Esos componentes de la CF relacionada con la salud se pueden ver afectados favorable o negativamente por el nivel de AF de cada persona. Las personas que realizan AF tienen a mostrar una mejor condici&#x00F3;n y rendimiento f&#x00ED;sico, resisten mejor al estr&#x00E9;s, presentan mejor &#x00E1;nimo, y se perciben ellos mismos con un mejor estado de salud y de calidad de vida (<xref ref-type="bibr" rid="CIT008">Andersen et al., 2017</xref>; <xref ref-type="bibr" rid="CIT078">Granger, Williams, Di Nardo, Harrison, &#x0026; Verma, 2017</xref>; <xref ref-type="bibr" rid="CIT170">Rosa-Guillam&#x00F3;n, Garc&#x00ED;a-Cant&#x00F3;, Rodr&#x00ED;guez-Garc&#x00ED;a, &#x0026; P&#x00E9;rez-Soto, 2017</xref>; <xref ref-type="bibr" rid="CIT189">Tereza Ara&#x00FA;jo &#x0026; Dosil, 2016</xref>). <xref ref-type="bibr" rid="CIT173">Ruiz et al. (2011)</xref> demuestran que existe una relaci&#x00F3;n entre la salud f&#x00ED;sica y los niveles de fuerza muscular, principalmente en los ni&#x00F1;os con sobrepeso y obesidad. Una aptitud muscular baja en la adolescencia es un signo de un perfil metab&#x00F3;lico bajo que se relaciona a la edad adulta con un incremento de enfermedades no-transmisibles (ENT) y un mayor riesgo de mortalidad prematura (<xref ref-type="bibr" rid="CIT163">Perna et al., 2016</xref>; <target target-type="page" id="pges_17"/><xref ref-type="bibr" rid="CIT165">Ram&#x00ED;rez-V&#x00E9;lez, Meneses-Echavez, Gonz&#x00E1;lez-Ru&#x00ED;z, &#x0026; Correa, 2014</xref>). La diminuci&#x00F3;n de la condici&#x00F3;n f&#x00ED;sica est&#x00E1; asociada a un aumento del &#x00CD;ndice de Masa Corporal (IMC) en los ni&#x00F1;os y adolescente (<xref ref-type="bibr" rid="CIT202">Utesch, Dreisk&#x00E4;mper, Strauss, &#x0026; Naul, 2018</xref>). Adem&#x00E1;s, la obesidad juvenil con lleva a un desarrollo precoz de patolog&#x00ED;as cr&#x00F3;nicas caracter&#x00ED;sticas de edades m&#x00E1;s avanzada como puede ser la hipertensi&#x00F3;n arterial (<xref ref-type="bibr" rid="CIT135">Marrod&#x00E1;n Serrano et al., 2013</xref>) o el h&#x00ED;gado graso (<xref ref-type="bibr" rid="CIT214">Woo Baidal et al., 2018</xref>). <xref ref-type="bibr" rid="CIT073">Friedemann et al. (2012)</xref> afirman que un ni&#x00F1;o obeso tiene m&#x00E1;s posibilidades de ser un adulto obeso con patolog&#x00ED;as relacionadas. Las consecuencias de la obesidad infantil o juvenil, no solo trae consecuencias al nivel de la salud f&#x00ED;sica y metab&#x00F3;lica, tambi&#x00E9;n como afirma <xref ref-type="bibr" rid="CIT038">Brixval et al. (2012)</xref> consecuencias psicosociales como puede ser la exclusi&#x00F3;n o el acoso escolar. Por lo tanto, una AF regular es un factor determinante en la prevenci&#x00F3;n y el tratamiento de la obesidad infantil y de los riesgos metab&#x00F3;licos asociados (<xref ref-type="bibr" rid="CIT112">Kuzik et al., 2017</xref>; <xref ref-type="bibr" rid="CIT148">Moore et al., 2017</xref>).</p>

<title><bold>Beneficios de la Actividad F&#x00ED;sica</bold></title>
<p>Una AF regular y de intensidad moderada o elevada, como hacer bicicleta o correr es beneficiosa por la salud personal. Contribuye a la prevenci&#x00F3;n de las ENT como pueden ser las enfermedades cardiovasculares, el c&#x00E1;ncer o la diabetes. Tambi&#x00E9;n reduce los s&#x00ED;ntomas de depresi&#x00F3;n y ansiedad. Permite una mejora de las capacidades de reflexi&#x00F3;n y aprendizaje, garant&#x00ED;a un crecimiento y desarrollo sano en los j&#x00F3;venes y previene los riesgos de mortalidad prematura (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>).</p>
<p>Los beneficios de la AF son superiores a los riesgos relacionados como accidentes y lesiones durante su pr&#x00E1;cticas (<xref ref-type="bibr" rid="CIT099">INSERM, 2019</xref>). Seg&#x00FA;n la OMS (<xref ref-type="bibr" rid="CIT216">World Health Organization, 2018</xref>) una AF regular reduce el riesgo de sufrir hipertensi&#x00F3;n, cardiopat&#x00ED;a, diabetes de tipo II, c&#x00E1;ncer de mama o accidente cerebrovascular. Tambi&#x00E9;n la AF ayuda en el control del peso corporal, reduce la hipertensi&#x00F3;n arterial y mejora el funcionamiento muscular y articular del cuerpo tanto en los j&#x00F3;venes como en las personas mayores (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>).</p>
<p>Para tener beneficios para la salud, la pr&#x00E1;ctica de AF se tiene que realizar a diferentes niveles de intensidad; intensidad baja, intensidad moderada e intensidad vigorosa. Estos niveles de intensidad est&#x00E1;n formados por conceptos como el &#x00CD;ndice metab&#x00F3;lico (MET) o equivalente metab&#x00F3;lico. Este &#x00FA;ltimo mide la intensidad de la AF y el consumo energ&#x00E9;tico.</p>
<p>Se define el MET en funci&#x00F3;n del metabolismo base del organismo, en reposo. La escala va desde el 0,9 MET (en sue&#x00F1;o) hasta 18 MET (carrera a 17,5km/h). La OMS (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>) define una actividad f&#x00ED;sica moderada entre 3 y 6 MET, es decir entre 3 y 6 veces el metabolismo en reposo, y <target target-type="page" id="pges_18"/>una actividad vigorosa a m&#x00E1;s de 6 MET. Una actividad insuficiente se considera entre 1,6 y 3 MET, es decir inferior a 3 veces el metabolismo de reposo. Toda actividad inferior a 1,6 MET es considerada como actividad sedentaria (<xref ref-type="bibr" rid="CIT011">ANSES, 2016</xref>).</p>
<p>La OMS (2020) preconiza unos tiempos m&#x00ED;nimo de AF por edades. En los adultos mayores de 18 a&#x00F1;os, se recomienda entre 150 min y 300 min de actividad aer&#x00F3;bica moderada o entre 75 min y 150 min de actividad aer&#x00F3;bica vigorosa por semana para mantener unos beneficios sustanciales para su salud.</p>
<p>En el caso de los j&#x00F3;venes de entre 5 y 17 a&#x00F1;os, la OMS (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>) recomienda uno 60 minutos de actividad aer&#x00F3;bica moderada o vigorosa diaria, adem&#x00E1;s de realizar al menos 3 d&#x00ED;as por semana actividades que fortalezcan los m&#x00FA;sculos y los huesos. Se entiende como AF moderada o vigorosa, toda actividad f&#x00ED;sica, donde el esfuerzo esta superior a 6 veces el propio esfuerzo en unas condiciones habituales. Para ser m&#x00E1;s preciso, se entiende que un ni&#x00F1;o de menos de 17 a&#x00F1;os que practica patines, patinetes, bicicleta o caminar r&#x00E1;pido est&#x00E1; haciendo una AF moderada. Un mismo joven que practica carrera, saltos, bicicleta intensa, artes marciales o cualquier deporte (Football, Baloncesto&#x2026;) est&#x00E1; practicando AF vigorosa (<xref ref-type="bibr" rid="CIT201">US Department of Health and Human Services, 2008</xref>). Al opuesto de la Actividad f&#x00ED;sica esta la inactividad. Todav&#x00ED;a, seg&#x00FA;n la OMS (2020), un ni&#x00F1;o est&#x00E1; considerado inactivo f&#x00ED;sicamente, cuando pasa m&#x00E1;s de 60 minutos sentado.</p>
<p>Una prevenci&#x00F3;n precoz del sobrepeso o de la obesidad, de un nivel bajo de AF o de una baja condici&#x00F3;n f&#x00ED;sica en los j&#x00F3;venes es de gran importancia, porque la AF total est&#x00E1; asociada favorablemente a los indicadores de salud f&#x00ED;sica, sociopsicol&#x00F3;gica y cognitiva en los ni&#x00F1;os de 15 a 17 a&#x00F1;os (<xref ref-type="bibr" rid="CIT202">Utesch et al., 2018</xref>). Adem&#x00E1;s, <xref ref-type="bibr" rid="CIT016">Augste et al.

Pero <target target-type="page" id="pges_19"/>existe una diferencia muy notable entre sexos. En el mismo trabajo (<xref ref-type="bibr" rid="CIT084">Guthold et al., 2020</xref>), los varones de entre 11 y 17 a&#x00F1;os alcanzan cifras del 69,8% de sedentarismo, frente al 83,8% de las chicas de la misma edad. En Espa&#x00F1;a, seg&#x00FA;n un estudio del <xref ref-type="bibr" rid="CIT142">Ministerio de Sanidad Consumo y Bienestar Social (2017)</xref> sobre el sedentarismo en el tiempo libre de los j&#x00F3;venes, el 30 % de los j&#x00F3;venes mayores de 14 a&#x00F1;os admit&#x00ED;an ser sedentarios en su tiempo libre. En el caso de los j&#x00F3;venes varones se alcanzaban cifras del 23,16 %, y en las mujeres el 37 % de las chicas de la misma edad se declaraban sedentarias.</p>
<p>A nivel de sobrepeso u obesidad, una de las consecuencias de la inactividad o del sedentarismo, m&#x00E1;s del 18 % de la poblaci&#x00F3;n mundial de edad comprendida entre 5 y 19 a&#x00F1;os tiene sobrepeso u obesidad (<xref ref-type="bibr" rid="CIT221">World Health Organization, 2021b</xref>) lo que representa m&#x00E1;s de 340 millones de ni&#x00F1;os.

<p>Las personas que no tienen un nivel suficiente de AF, seg&#x00FA;n la OMS, presentan un riesgo de mortalidad superior al 20 % o 30 % m&#x00E1;s que las personas con un nivel de AF suficiente (<xref ref-type="bibr" rid="CIT216">World Health Organization, 2018</xref>). <xref ref-type="bibr" rid="CIT191">Thorp et al. (2011)</xref> y <xref ref-type="bibr" rid="CIT213">Wilmot et al. (2012)</xref> demostraron la relaci&#x00F3;n directa entre el sedentarismo y la mortalidad en general. Una revisi&#x00F3;n sistem&#x00E1;tica publicada en 2018 (<xref ref-type="bibr" rid="CIT161">Patterson et al., 2018</xref>), demuestra que el tiempo sentado es inversamente proporcional a los riesgos de mortalidad. Es decir que m&#x00E1;s tiempo una persona pasa sentada, m&#x00E1;s riesgos de mortalidad tiene. En <xref ref-type="bibr" rid="CIT105">2014</xref>, Katzmarzyk, en su estudio de cohorte sobre 16586 canadienses de 18 a 90 a&#x00F1;os, durante un seguimiento de 12 a&#x00F1;os, mostraba como las personas f&#x00ED;sicamente inactivas, que pasan m&#x00E1;s tiempo de pie, ten&#x00ED;an menos riesgos de mortalidad que las personas f&#x00ED;sicamente inactivas que pasan mucho tiempo sentados. Exist&#x00ED;a menos riesgo de mortalidad en sedentarios que permanecen de pie respecto a ser sedentario sentado. La disminuci&#x00F3;n de mortalidad var&#x00ED;a entre el 21 % al 35 % respectivamente para las personas sentadas y las personas de pie. En Estados Unidos, el estudio de cohorte de 3 a&#x00F1;os NHANES 2003-2004 (<xref ref-type="bibr" rid="CIT110">Koster et al., 2012</xref>), demostr&#x00F3; en 1906 personas, con medici&#x00F3;n de actividad por aceler&#x00F3;metro, que el factor de riesgo de mortalidad se multiplicaba por 5 en las personas m&#x00E1;s sedentarias (m&#x00E1;s de 73 % del tiempo despierto dedicado a actividades sedentarias).</p>
<p><target target-type="page" id="pges_20"/><xref ref-type="bibr" rid="CIT023">Benjaminsen-Borch et al. (2011)</xref> se centraron en 66136 mujeres de entre 30 y 70 a&#x00F1;os en un periodo de hasta 11 a&#x00F1;os, mostrando como los riesgos de mortalidad son mayores en las mujeres que practican poca AF. Este riesgo se puede multiplicarse hasta un 2,35 m&#x00E1;s en las mujeres menos activas. Los autores se&#x00F1;alan que 11,5 % de la mortalidad prematura es por causa de falta de AF. (<xref ref-type="bibr" rid="CIT083">Gulsvik et al., 2012</xref>) describen como existe una diminuci&#x00F3;n de hasta 37 % de mortalidad en las personas que practican una AF elevada, y un 25 % menos en las personas que practican AF moderada frente a las personas que no practican suficiente AF.</p>
<p>(<xref ref-type="bibr" rid="CIT063">Ekelund et al., 2019</xref>) en su meta-an&#x00E1;lisis sobre los efectos del sedentarismo en el riesgo de mortalidad en general, con un total de m&#x00E1;s de 36000 participantes sobre un tiempo medio de 5,8 a&#x00F1;os de seguimiento, confirman que cuanto m&#x00E1;s aumenta el tiempo de sedentarismo, m&#x00E1;s aumentan los riesgos de mortalidad. Concretamente de entre 28 % y hasta 163 % m&#x00E1;s de riesgo de mortalidad cuanto m&#x00E1;s tiempo se pasa sentado, en funci&#x00F3;n del estatus socioecon&#x00F3;mico, la edad, el IMC o el sexo. En este estudio <xref ref-type="bibr" rid="CIT063">Ekelund et al.

<title><bold>Efecto de la Actividad F&#x00ED;sica sobre las enfermedades no transmisibles.</bold></title>
<p>La OMS (2020b) preconiza la pr&#x00E1;ctica de AF como herramienta para luchar contra el sedentarismo y reducir la mortalidad causado por las ENT y aumentar la esperanza de vida. <xref ref-type="bibr" rid="CIT118">Lee et al. (2012)</xref> calculan que, si se reduce la inactividad f&#x00ED;sica de entre 10 % a 25 %, se podr&#x00ED;a reducir de entre 533000 hasta 1,3 millones de muertes al a&#x00F1;o. La eliminaci&#x00F3;n de la inactividad f&#x00ED;sica reducir&#x00ED;a entre 6 % y 10 % de las principales ENT, como las enfermedades cardiovasculares, la diabetes tipo II, o los canceres de mama y de colon (<xref ref-type="bibr" rid="CIT220">World Health Organization, 2021a</xref>).</p>
<p>La falta de AF aumenta considerablemente las ENT, que son uno de los factores m&#x00E1;s importante de muertes prematuras en el mundo (<xref ref-type="bibr" rid="CIT220">World Health Organization, 2021a</xref>). M&#x00E1;s del 70 % de las muertes en el mundo son a causa de las ENT (<xref ref-type="bibr" rid="CIT220">World Health Organization, 2021a</xref>), destacando cuatro grupos principales como las enfermedades cardiovasculares, el c&#x00E1;ncer, las enfermedades respiratorias y la diabetes (<xref ref-type="bibr" rid="CIT220">World Health Organization, 2021a</xref>).</p>
<p><target target-type="page" id="pges_21"/>La AF representa un elemento importante para prevenir o retrasar la ocurrencia de la diabetes de tipo 2 (<xref ref-type="bibr" rid="CIT006">American Diabetes Association, 2015</xref>; <xref ref-type="bibr" rid="CIT121">Li et al., 2014</xref>). Varias meta-an&#x00E1;lisis (<xref ref-type="bibr" rid="CIT107">Kodama et al., 2013</xref>; <xref ref-type="bibr" rid="CIT184">Sluik et al., 2012</xref>) incluyendo cohorte importante de pacientes se han interesado a los efectos de la AF sobre la mortalidad por causa de la diabetes de tipo 2. Estos estudios muestran una relaci&#x00F3;n linear inversa entre la cantidad de AF y la mortalidad a causa de la diabetes de tipo 2. Los pacientes que practican una AF moderada o elevada tienen menos riesgos de padecer mortalidad (-20 a -50%) que los pacientes que no practican AF. En el estudio de <xref ref-type="bibr" rid="CIT184">Sluik et al. (2012)</xref> el grupo que presentaba la reducci&#x00F3;n de mortalidad m&#x00E1;s importante era, o bien los pacientes que ten&#x00ED;an una AF moderada o bien un tiempo de ocio activos de los m&#x00E1;s elevados. En otro estudio (<xref ref-type="bibr" rid="CIT121">Li et al., 2014</xref>), un programa de intervenci&#x00F3;n de AF de 6 a&#x00F1;os en paciente con intolerancia a la glucosa permiti&#x00F3; reducir la incidencia de mortalidad por causa de la diabetes de tipo 2.</p>
<p>Una AF regular de intensidad moderada o elevada est&#x00E1; asociada a una disminuci&#x00F3;n del 20% hasta 50% de los riesgos de patolog&#x00ED;as coronarias y de hasta el 60% de accidentes vasculares (<xref ref-type="bibr" rid="CIT117">Lee et al., 2014</xref>; <xref ref-type="bibr" rid="CIT206">Wanner et al., 2014</xref>). Oldridge (2012) en su meta-an&#x00E1;lisis con 13824 pacientes incluidos en un programa de readaptaci&#x00F3;n cardiaca, mostraban resultados donde se reduc&#x00ED;a hasta 30% la mortalidad de origen cardiaca. (<xref ref-type="bibr" rid="CIT193">Tikkanen, Gustafsson, &#x0026; Ingelsson, 2018</xref>) muestra que un alto nivel de aptitud cardiorrespiratoria se asocia con una diminuci&#x00F3;n de hasta 49% menos de riesgos de enfermedades coronarias y hasta un 60% menos de riesgos de fibrilaci&#x00F3;n auricular. En este estudio (<xref ref-type="bibr" rid="CIT193">Tikkanen et al., 2018</xref>), los autores mostraron como en los niveles m&#x00E1;s altos de fuerza de agarre, de AF y de capacidad cardiorrespiratoria permiten una diminuci&#x00F3;n de los riesgos de enfermedades cardiovasculares.</p>
<p>En la prevenci&#x00F3;n de los canceres, la pr&#x00E1;ctica de una AF est&#x00E1; asociada a una disminuci&#x00F3;n de 25% de los canceres de colon (<xref ref-type="bibr" rid="CIT034">Boyle, Keegel, Bull, Heyworth, &#x0026; Fritschi, 2012</xref>; <xref ref-type="bibr" rid="CIT074">Friedenreich, Neilson, &#x0026; Lynch, 2010</xref>) y de 27% de los canceres de pecho (<xref ref-type="bibr" rid="CIT127">Lynch, Neilson, &#x0026; Friedenreich, 2011</xref>). La reducci&#x00F3;n del riesgo de c&#x00E1;ncer de colon es equivalente con una AF profesional, de ocio o dom&#x00E9;stica. Con un aumento de 30 min/d de AF de ocio, la diminuci&#x00F3;n de riesgos de c&#x00E1;ncer de colon ha sido estimada en un 12% (<xref ref-type="bibr" rid="CIT099">INSERM, 2019</xref>; <xref ref-type="bibr" rid="CIT215">World Cancer Research Fund &#x0026; American Institute for Cancer, 2011</xref>). La diminuci&#x00F3;n de riesgos de c&#x00E1;ncer de pecho ha sido confirmado por (<xref ref-type="bibr" rid="CIT222">Wu, Zhang, &#x0026; Kang, 2013</xref>) pero en proporci&#x00F3;n inferiores, igual a 12% en las mujeres que tienen los niveles m&#x00E1;s altos de AF de ocio. Esa reducci&#x00F3;n de riesgos de c&#x00E1;ncer de pecho ha sido confirmada en todos los tipos de AF, pero en proporciones diferentes. Las AF de ocio o domesticas reduce hasta 21% los riesgos, comparado con las AF ligadas a los transportes (andar, bici) hasta 18% y las AF ligadas a la actividad profesional hasta un 13% de diminuci&#x00F3;n (<xref ref-type="bibr" rid="CIT127">Lynch et al., 2011</xref>; <xref ref-type="bibr" rid="CIT222">Wu et al., 2013</xref>).</p>
<p><target target-type="page" id="pges_22"/>En las enfermedades osteo-articulares, tambi&#x00E9;n se evidencia mejoras de la masa &#x00F3;sea.

<p>Otros aspectos clave, es el efecto de la AF sobre enfermedades como la depresi&#x00F3;n, la ansiedad o el estr&#x00E9;s psicol&#x00F3;gico (<xref ref-type="bibr" rid="CIT015">Asmundson et al., 2013</xref>; <xref ref-type="bibr" rid="CIT124">Lindwall, Gerber, Jonsdottir, B&#x00F6;rjesson, &#x0026; Ahlborg, 2014</xref>; <xref ref-type="bibr" rid="CIT146">Mollart, Skinner, Newing, &#x0026; Foureur, 2013</xref>)</p>
<p>En Europa, la investigaci&#x00F3;n HELENA (<xref ref-type="bibr" rid="CIT055">Cristi-Montero et al., 2019</xref>), muestra que los ni&#x00F1;os que tienen una AF extraescolar mejoran sus condiciones cardiorrespiratorias por encima de los valores de referencia de los adultos, y tambi&#x00E9;n mejoran la salud mental. Adem&#x00E1;s, las AF no solamente tiene beneficios sobre la salud f&#x00ED;sica, tambi&#x00E9;n sobre la salud psicol&#x00F3;gica, donde reduce la depresi&#x00F3;n, la ansiedad o las fobias (<xref ref-type="bibr" rid="CIT029">Biddle &#x0026; Asare, 2011</xref>; <xref ref-type="bibr" rid="CIT030">Biddle, Ciaccioni, Thomas, &#x0026; Vergeer, 2019</xref>; <xref ref-type="bibr" rid="CIT085">Hale, Colquhoun, Lancastle, Lewis, &#x0026; Tyson, 2021</xref>; <xref ref-type="bibr" rid="CIT186">Spruit, Assink, van Vugt, van der Put, &#x0026; Stams, 2016</xref>).

Pero tambi&#x00E9;n, estudios previos (<xref ref-type="bibr" rid="CIT139">McClure, Tanski, Kingsbury, Gerrard, &#x0026; Sargent, 2010</xref>; <xref ref-type="bibr" rid="CIT144">Moksnes &#x0026; Reidunsdatter, 2019</xref>) muestran que ese aumento de autoestima es mayor en los ni&#x00F1;os que en las ni&#x00F1;as, por lo que hay una diferencia de g&#x00E9;nero que hay que tener en cuenta. La AF no solamente previene las apariciones de enfermedades psicol&#x00F3;gicas como la depresi&#x00F3;n, pero tambi&#x00E9;n muestran que la pr&#x00E1;ctica de AF ayuda a los j&#x00F3;venes que tienen alguna enfermedad depresiva a mejorar su enfermedad (<xref ref-type="bibr" rid="CIT017">Axelsd&#x00F3;ttir, Biedil&#x00E6;, Sagatun, Nordheim, &#x0026; Larun, 2021</xref>).

Las familias se dirigen hacia alimentos m&#x00E1;s baratos y con valores cal&#x00F3;ricos superiores a tratarse generalmente de alimentos s&#x00FA;per procesados. La alimentaci&#x00F3;n poco saludable y la conducta alimentaria tiene consecuencia sobre la obesidad infantil (<xref ref-type="bibr" rid="CIT174">Sahoo et al., 2015</xref>). A modo de ejemplo, los escolares con sobrepeso u obesidad desayunan con menos frecuencia que los dem&#x00E1;s y sobre todo comen con m&#x00E1;s regularidad fuera de casa (<xref ref-type="bibr" rid="CIT032">Blondin, Anzman-Frasca, Djang, &#x0026; Economos, 2016</xref>; <xref ref-type="bibr" rid="CIT075">Garc&#x00ED;a-Solano et al., 2021</xref>).</p>
<p>Otro factor social y comunitario se puede relacionar con el exceso de uso de pantallas en los j&#x00F3;venes (<xref ref-type="bibr" rid="CIT159">Oswald, Rumbold, Kedzior, &#x0026; Moore, 2020</xref>). Cada vez m&#x00E1;s, las pantallas est&#x00E1;n presentes en sus vidas, y el porcentaje de j&#x00F3;venes que tienen aparatos electr&#x00F3;nicos no para de aumentar (<xref ref-type="bibr" rid="CIT098">INE, 2020</xref>). En 2011, 70,3% de los hogares espa&#x00F1;oles dispon&#x00ED;an de alg&#x00FA;n ordenador y 16,3% dispon&#x00ED;an de Tablet. En 2020, estas cifras han subido hasta 81,4% y 58,4% respectivamente. Por lo que corresponde del acceso a los m&#x00F3;viles, los j&#x00F3;venes de entre 10 y 15 a&#x00F1;os son 69,5% en tener un m&#x00F3;vil en 2020, frente al 66,7% en 2010. Tambi&#x00E9;n aumento el uso de internet por parte de <target target-type="page" id="pges_24"/>los j&#x00F3;venes. Si es 2010 eran 87,3% en hacer uso de internet, en 2020, son 94,5% en utilizarlo con regularidad (<xref ref-type="bibr" rid="CIT098">INE, 2020</xref>). Adem&#x00E1;s, la presencia de esos aparatos electr&#x00F3;nicos es mayor en los j&#x00F3;venes con sobrepeso u obesidad (<xref ref-type="bibr" rid="CIT075">Garc&#x00ED;a-Solano et al., 2021</xref>). La utilizaci&#x00F3;n cada vez mayor de pantallas en el tiempo libre de los alumnos, conduce a menor actividad f&#x00ED;sica (<xref ref-type="bibr" rid="CIT059">De Jong et al., 2013</xref>), mayor exposici&#x00F3;n a la publicidad de alimentos no saludables o a un consumo excesivo de alimentos por distracci&#x00F3;n mientras utilizan dichos dispositivos (<xref ref-type="bibr" rid="CIT178">Santaliestra-Pas&#x00ED;as, Rey-L&#x00F3;pez, &#x0026; Moreno Aznar, 2013</xref>). <xref ref-type="bibr" rid="CIT116">Seg&#x00FA;n Lavielle-Sotomayor et al.

<p>La barrera cultural es otro factor que influye sobre la pr&#x00E1;ctica de AF. El bajo nivel de instrucci&#x00F3;n de los padres o la barrera ling&#x00FC;&#x00ED;stica son limitadores (<xref ref-type="bibr" rid="CIT149">Mude &#x0026; Mwanri, 2016</xref>). Los estereotipos de genero ligados a la cultura es otro factor cultural limitador de la pr&#x00E1;ctica de AF. La existencia de una discriminaci&#x00F3;n de g&#x00E9;nero en la pr&#x00E1;ctica de AF entre hombre y mujeres puede ser considerado como un fen&#x00F3;meno mundial (<xref ref-type="bibr" rid="CIT004">Althoff et al., 2017</xref>). Esas diferencias se pueden explicar por la etnicidad o la religi&#x00F3;n. <xref ref-type="bibr" rid="CIT182">Sharara, Akik, Ghattas, &#x0026; Makhlouf Obermeyer (2018)</xref> afirman que las familias privilegian las actividades espirituales y educativas frente a las AF de ocio. <xref ref-type="bibr" rid="CIT042">Adem&#x00E1;s, Capllonch, Godall, &#x0026; Lleix&#x00E0; Arribas (2007)</xref> describe como algunas creencias religiosas puede limitar la pr&#x00E1;ctica de AF en las mujeres por aspectos ligados a la exposici&#x00F3;n de partes desnudas del cuerpo como en atletismo o la nataci&#x00F3;n adem&#x00E1;s de la pr&#x00E1;ctica conjunta con los hombres.</p>
<p>La inmigraci&#x00F3;n tambi&#x00E9;n es un aspecto en tener en cuenta como factor limitador de la pr&#x00E1;ctica de AF. Pertenecer a una familia inmigrante se asocia positivamente con un descenso de la AF y un mayor riesgo de obesidad (<xref ref-type="bibr" rid="CIT082">Gualdi-Russo et al., 2014</xref>; <xref ref-type="bibr" rid="CIT151">Murer, Saarsalu, Zimmermann, &#x0026; Herter-Aeberli, 2016</xref>; <xref ref-type="bibr" rid="CIT177">S&#x00E1;nchez-Mart&#x00ED;nez et al., 2016</xref>). Una familia inmigrante acumula las diferentes barreras anteriormente citadas como factor limitador a la pr&#x00E1;ctica de AF. Las familias inmigrantes pertenecen a un nivel socioecon&#x00F3;mico bajo, con una cultura diferente a la cultura del pa&#x00ED;s acogedor y a veces con una religi&#x00F3;n diferente. En Espa&#x00F1;a, seg&#x00FA;n los datos del INE (<xref ref-type="bibr" rid="CIT166">Reher et al., 2008</xref>), los inmigrantes son etiquetados principalmente como inmigrantes econ&#x00F3;micos, efectuando trabajos poco cualificados y encontr&#x00E1;ndose en los niveles inferiores de la escala socio econ&#x00F3;mica. Trabajan en puestos de trabajo poco cualificados y con una remuneraci&#x00F3;n baja y se perpetua con largas jornadas laborales. Otros estudios realizados en Espa&#x00F1;a (<xref ref-type="bibr" rid="CIT077">Gonzalo-Almorox &#x0026; Urbanos-Garrido, 2016</xref>; <xref ref-type="bibr" rid="CIT145">Molina-Garc&#x00ED;a, Queralt, Adams, Conway, &#x0026; Sallis, 2017</xref>), confirman que los ni&#x00F1;os y adolescentes que viven en barrios con bajo nivel socio econ&#x00F3;mico son menos activos.</p>
<p><target target-type="page" id="pges_25"/>Ultimo factor o barrera a la pr&#x00E1;ctica de AF, es la familia. Los padres y madres en el contexto familiar pueden convertirse en moduladores de la pr&#x00E1;ctica de AF por parte de los j&#x00F3;venes. Entre los factores dentro de las familias que limitan la AF se encuentran, la falta de tiempo por causa de trabajo, el cansancio laboral, o la conciliaci&#x00F3;n familiar son unos de las causas de la falta de implicaci&#x00F3;n de los padres y madres en la pr&#x00E1;ctica de sus hijos (<xref ref-type="bibr" rid="CIT089">K. R. Hesketh, Lakshman, &#x0026; van Sluijs, 2017</xref>). Incluso, hay madres que afirman que la influencia de los padres sobre el comportamiento saludables de los hijos es superior a la suya (<xref ref-type="bibr" rid="CIT158">Olvera, Hammons, Teran-Garcia, Plaza-Delestre, &#x0026; Fiese, 2021</xref>). Adem&#x00E1;s, las familias de ni&#x00F1;os inmigrantes pueden dar una mayor prioridad a la carga acad&#x00E9;mica que a la pr&#x00E1;ctica de AF, al percibir que es una herramienta de ascenso social (<xref ref-type="bibr" rid="CIT198">Trigwell et al., 2015</xref>). Por otro lado, los padres y madres pueden ser facilitadores a la hora de realizar AF y tener un comportamiento saludable. Las familias que participan junto con sus hijos son un factor facilitador de una mayor pr&#x00E1;ctica de AF por parte de los j&#x00F3;venes (<xref ref-type="bibr" rid="CIT024">Bentley, Jago, &#x0026; Turner, 2015</xref>; <xref ref-type="bibr" rid="CIT058">De Craemer et al., 2013</xref>; <xref ref-type="bibr" rid="CIT156">O&#x2019;Connor et al., 2013</xref>; <xref ref-type="bibr" rid="CIT187">Suen, Cerin, &#x0026; Wu, 2015</xref>). Adem&#x00E1;s, la motivaci&#x00F3;n, los est&#x00ED;mulos positivos hacia la AF o la inculcaci&#x00F3;n del valor e importancia de la AF son otros factores positivos que influencian positivamente en tener comportamientos saludables por parte de los j&#x00F3;venes (<xref ref-type="bibr" rid="CIT088">K.

<title><bold>Grupos vulnerables y de riesgo de inactividad f&#x00ED;sica</bold></title>
<p>Los grupos sociales considerados vulnerables tienen un mayor riesgo de adoptar comportamientos poco saludables y a ser menos activos que los grupos no vulnerables (<xref ref-type="bibr" rid="CIT113">Labree et al., 2014</xref>). <xref ref-type="bibr" rid="CIT120">Lewis et al. (2012)</xref> define grupo vulnerable como grupos y comunidades con un mayor riesgo de mala salud como resultado de las barreras que experimentan a los recursos sociales, econ&#x00F3;micos, pol&#x00ED;ticos y ambientales, as&#x00ED; como las limitaciones debidas a enfermedades o discapacidades. Seg&#x00FA;n la definici&#x00F3;n que propone <xref ref-type="bibr" rid="CIT120">Lewis et al. (2012)</xref> sobre los grupos vulnerables, se identifican dos grupos. Por un lado, las poblaciones de riesgo cl&#x00ED;nico, es decir poblaciones con condiciones cl&#x00ED;nicas o factores de riesgo que les hacen correr el riesgo de tener una mala salud. Por otro lado, los grupos de poblaciones socialmente desfavorecidos. Se entiende ese segundo grupo por las minor&#x00ED;as raciales, los pobres, y personas con escaso apoyo social. De este modo, los ni&#x00F1;os de familias que se declaran con un nivel socioecon&#x00F3;mico bajo (pocos ingresos y nivel de educaci&#x00F3;n bajo) presentan un porcentaje mayor en padecer sobrepeso y obesidad que las familias con un nivel socioecon&#x00F3;mico alto (<xref ref-type="bibr" rid="CIT096">Iguacel, Fern&#x00E1;ndez-Alvira, Labayen, et al., 2018</xref>).</p>
<p>Otro aspecto clave, son las situaciones que, debido a los fen&#x00F3;menos culturales o religiosos ligados a la diferencia de g&#x00E9;nero, se convierten en factores a <target target-type="page" id="pges_26"/>considerar a la hora de practicar AF (<xref ref-type="bibr" rid="CIT198">Trigwell et al., 2015</xref>). El significado dado por una determinada cultura, etnia o religi&#x00F3;n al cuerpo es imprescindible para poder programar o promover la AF. El hecho de exponer partes del cuerpo a la vista para practicar ciertas AF son culturalmente cargados de sentido, y va cambiando en funci&#x00F3;n del sexo, de la edad y las responsabilidades en el seno de la familia (<xref ref-type="bibr" rid="CIT115">Lang&#x00F8;ien et al., 2017</xref>). <xref ref-type="bibr" rid="CIT115">Seg&#x00FA;n Lang&#x00F8;ien et al. (2017)</xref> las exigencias religiosas sobre la manera de vestirse o las limitaciones en pasar tiempo junto al sexo opuesto pueden limitar la pr&#x00E1;ctica de AF.</p>
<p>En Espa&#x00F1;a, en la encuesta de nacional de Salud del a&#x00F1;o 2017 (<xref ref-type="bibr" rid="CIT142">Ministerio de Sanidad Consumo y Bienestar social, 2017</xref>), se identifican diferencias en relaci&#x00F3;n a la AF, entre las personas que nacieron en Espa&#x00F1;a y las personas que nacieron en el extranjero. Seg&#x00FA;n esta encuesta 28,31 % de los j&#x00F3;venes (15-24 a&#x00F1;os) nacidos en Espa&#x00F1;a admiten ser sedentarios, frente al 39,29 % de las personas nacidas en el extranjero. Varias investigaciones en otros pa&#x00ED;ses, como EEUU o Inglaterra, reflejar esa tendencia donde los j&#x00F3;venes extranjeros practican menos AF y son m&#x00E1;s sedentarios (<xref ref-type="bibr" rid="CIT026">Bhatnagar et al., 2015</xref>; <xref ref-type="bibr" rid="CIT035">Brewer &#x0026; Kimbro, 2014</xref>; <xref ref-type="bibr" rid="CIT065">Eyre &#x0026; Duncan, 2013</xref>; <xref ref-type="bibr" rid="CIT081">Griffiths et al., 2013</xref>; <xref ref-type="bibr" rid="CIT198">Trigwell et al., 2015</xref>). En Inglaterra, <xref ref-type="bibr" rid="CIT081">Griffiths et al. (2013)</xref> se&#x00F1;alan como los ni&#x00F1;os mayores de 7 a&#x00F1;os de familias extranjeras presentan un nivel de AF bajo, frente a los ni&#x00F1;os de familias brit&#x00E1;nicas. Estudios previos (<xref ref-type="bibr" rid="CIT025">Besharat Pour et al., 2014</xref>; <xref ref-type="bibr" rid="CIT080">Greier, Ruedl, &#x0026; Riechelmann, 2017</xref>; <xref ref-type="bibr" rid="CIT090">Hilpert et al., 2017</xref>), muestran como los ni&#x00F1;os suecos con padres inmigrantes tienen un riesgo mayor de tener una baja AF y tener sobrepeso. <xref ref-type="bibr" rid="CIT090">Hilpert et al.

Otros estudios previos muestran un aumento de ciertas ENT (c&#x00E1;ncer del &#x00FA;tero o c&#x00E1;ncer de pecho) junto a diferentes tendencias de mortalidad y una subutilizaci&#x00F3;n del sistema de salud en las poblaciones inmigrantes (<xref ref-type="bibr" rid="CIT027">Bianco, Larosa, Pileggi, Nobile, &#x0026; Pavia, 2016</xref>, <xref ref-type="bibr" rid="CIT028">2017</xref>; <xref ref-type="bibr" rid="CIT040">Brzoska &#x0026; Razum, 2017</xref>; <xref ref-type="bibr" rid="CIT205">Villarroel &#x0026; Artazcoz, 2016</xref>). En Europa, los ni&#x00F1;os inmigrantes procedentes de algunas regiones de &#x00C1;frica, presentaban una prevalencia m&#x00E1;s elevado de sobrepeso y obesidad respecto a los ni&#x00F1;os/as de origen Europeo (<xref ref-type="bibr" rid="CIT196">Toselli, Zaccagni, Celenza, Albertini, &#x0026; Gualdi-Russo, 2015</xref>).</p>
<p>Adem&#x00E1;s, <xref ref-type="bibr" rid="CIT172">Ruedl et al. (2019)</xref> se&#x00F1;alan que los j&#x00F3;venes inmigrantes tienen a tener un nivel de condici&#x00F3;n f&#x00ED;sica m&#x00E1;s bajo comparada con j&#x00F3;venes aut&#x00F3;ctonos. <xref ref-type="bibr" rid="CIT172">Ruedl et al. (2019)</xref> describe como los j&#x00F3;venes inmigrantes tienen un IMC m&#x00E1;s alto y el doble de riesgo de padecer sobrepeso u obesidad. Estos j&#x00F3;venes pasan m&#x00E1;s tiempo frente a una pantalla que los j&#x00F3;venes no inmigrantes (<xref ref-type="bibr" rid="CIT090">Hilpert et al., 2017</xref>; <xref ref-type="bibr" rid="CIT097">Iguacel, Fern&#x00E1;ndez-Alvira, Bammann, et al., 2018</xref>; <xref ref-type="bibr" rid="CIT104">Kaiser-Jovy, Scheu, &#x0026; Greier, 2017</xref>). La mayor utilizaci&#x00F3;n de las pantallas observado en los j&#x00F3;venes inmigrantes tiene como consecuencia una bajada de la pr&#x00E1;ctica de <target target-type="page" id="pges_27"/>AF, unido a un peor descanso y sue&#x00F1;o nocturno (<xref ref-type="bibr" rid="CIT014">Arriscado, Muros, Zabala, &#x0026; Mar&#x00ED;a Dalmau, 2015</xref>).</p>
<p>Por otro lado, los j&#x00F3;venes de origen inmigrante son menos susceptibles de practicar alguna AF dentro de un club deportivo. La tasa de participaci&#x00F3;n de esos j&#x00F3;venes es inferior a la tasa de participaci&#x00F3;n de los j&#x00F3;venes no inmigrantes (<xref ref-type="bibr" rid="CIT039">Brug et al., 2012</xref>; <xref ref-type="bibr" rid="CIT168">Reimers, Jekauc, Peterhans, Wagner, &#x0026; Woll, 2013</xref>; <xref ref-type="bibr" rid="CIT227">Zaccagni, Toselli, Celenza, Albertini, &#x0026; Gualdi-Russo, 2017</xref>). Por el contrario, los adolescentes inmigrantes tienen m&#x00E1;s posibilidades de practicar una AF extraescolar, dentro del propio centro educativo. Los programas extraescolares deportivos son en general gratuito o accesibles econ&#x00F3;micamente, tienen lugar en el propio centro escolar o en la zona muy cercana a la escuela a la cual acuden los j&#x00F3;venes, por lo que la pr&#x00E1;ctica de AF extraescolares a trav&#x00E9;s de programas especiales es m&#x00E1;s importante en la poblaci&#x00F3;n inmigrante que en la poblaci&#x00F3;n aut&#x00F3;ctona (<xref ref-type="bibr" rid="CIT167">Reimers et al., 2019</xref>). Parece que el contexto escolar proporciona un efecto protector sobre la pr&#x00E1;ctica de AF en los j&#x00F3;venes (<xref ref-type="bibr" rid="CIT101">Jim&#x00E9;nez Boraita, Arriscado Alsina, Dalmau Torres, &#x0026; Gargallo Ibort, 2020</xref>). La escuela tiene un papel importante en lucha contra el sedentarismo en general, y sobre todo en algunas poblaciones vulnerables como puede ser la poblaci&#x00F3;n inmigrante (<xref ref-type="bibr" rid="CIT101">Jim&#x00E9;nez Boraita et al., 2020</xref>). <xref ref-type="bibr" rid="CIT091">Horenczyk &#x0026; Tatar (2012)</xref> destacan el papel integrador que ofrece el contexto escolar a la poblaci&#x00F3;n migrante, proporcionando a las familias un entorno favorable para el contacto con la cultura y la sociedad de acogida. No solamente existe los programas extraescolares en la escuela, tambi&#x00E9;n la asignatura de educaci&#x00F3;n f&#x00ED;sica (EF). La EF posee una dimensi&#x00F3;n pedag&#x00F3;gica que no siempre tiene el deporte (<xref ref-type="bibr" rid="CIT046">Carter-Thuillier, L&#x00F3;pez Pastor, &#x0026; Gallardo Fuentes, 2016</xref>). As&#x00ED; la EF es una herramienta significativa y enriquecedor para desarrollar y alcanzar objetivos educativos interculturales (<xref ref-type="bibr" rid="CIT147">Monzon&#x00ED;s Mart&#x00ED;nez &#x0026; Capllonch Bujosa, 2015</xref>). La escuela en general y la EF en particular son &#x00E1;mbitos importantes para lograr la inclusi&#x00F3;n del alumnado extranjero en la sociedad utilizando el lenguaje del movimiento para lograrlo (<xref ref-type="bibr" rid="CIT185">Soler Prat, Flores Aguilar, &#x0026; Prat Grau, 2012</xref>). La comunicaci&#x00F3;n motriz es un lenguaje universal que ayuda a superar los obst&#x00E1;culos ligados al idioma que los inmigrantes pueden encontrar, por lo que la materia de EF tiene ventajas sobre otras materias educativas (<xref ref-type="bibr" rid="CIT070">Flores Aguilar, 2013</xref>). Por lo que los programas deportivos y la asignatura de EF dirigidos a las poblaciones vulnerables, son beneficiosos para crear espacios inclusivos, e interrelaciones entre las culturas, favoreciendo la integraci&#x00F3;n y el bienestar del alumnado migrante (<xref ref-type="bibr" rid="CIT101">Jim&#x00E9;nez Boraita et al., 2020</xref>).</p>
<p>Por &#x00FA;ltimo, la acumulaci&#x00F3;n de factores que fomentan la vulnerabilidad, como puede ser el nivel socioecon&#x00F3;mico, la baja formaci&#x00F3;n educativa de los padres, problemas de socializaci&#x00F3;n, aumentan el riesgo de comportamientos poco saludables (<xref ref-type="bibr" rid="CIT095">Iguacel et al., 2016</xref>; <xref ref-type="bibr" rid="CIT114">Labree et al., 2015</xref>).</p>

Los ni&#x00F1;os est&#x00E1;n influenciados por el medio en el cual viven como puede ser la familia, la escuela, la comunidad y/o la sociedad. Uno de los factores m&#x00E1;s relevantes de los ni&#x00F1;os son los padres y madres, los cuales construyen el modelo a seguir por los ni&#x00F1;os y el aprendizaje se realiza a trav&#x00E9;s de la imitaci&#x00F3;n (<xref ref-type="bibr" rid="CIT001">Adkins, Sherwood, Story, &#x0026; Davis, 2004</xref>; <xref ref-type="bibr" rid="CIT049">Cleland, Venn, Fryer, Dwyer, &#x0026; Blizzard, 2005</xref>). La cultura o la comunidad es otro factor de influencia sobre los ni&#x00F1;os (<xref ref-type="bibr" rid="CIT111">Kumanyika, 2008</xref>). Las actitudes culturales son propicias a modificar la relaci&#x00F3;n con la AF, como puede ser la sobreprotecci&#x00F3;n de los ni&#x00F1;os por parte de las familias (<xref ref-type="bibr" rid="CIT062">Dwyer et al., 2008</xref>), dar m&#x00E1;s importancia a la escolarizaci&#x00F3;n frente al bienestar f&#x00ED;sico (<xref ref-type="bibr" rid="CIT062">Dwyer et al., 2008</xref>) o bien una expectativa diferente frente a la AF en funci&#x00F3;n del sexo (<xref ref-type="bibr" rid="CIT171">Rothe et al., 2010</xref>).</p>

<p><bold><italic>El enfoque relativista</italic></bold> a trav&#x00E9;s del multiculturalismo o separaci&#x00F3;n, que es el hecho de mantener su propia cultura y no querer relacionarse con el pa&#x00ED;s acogedor debiendo vivir por lo tanto en espacios separados. Esta &#x00F3;ptica, puede dar pie a una forma de racismo y segregaci&#x00F3;n entre grupos poblacionales.</p>
<p><bold><italic>El enfoque comunicativo o interculturalismo</italic></bold> que quiere que ninguna cultura este por encima de la otra, promoviendo la igualdad cultural, por lo que las diferencias culturales mantienen y desarrollan las diferentes entidades culturales, fomenta el dialogo entre culturas.</p>
<p>La aculturaci&#x00F3;n deber&#x00ED;a ser un factor que considerar a la hora de analizar las diferencias de AF entre ni&#x00F1;os/as y j&#x00F3;venes nativos y extranjeros. La aculturaci&#x00F3;n est&#x00E1; asociada a cambios de vida elegidos y otros impuestos (<xref ref-type="bibr" rid="CIT002">Alidu &#x0026; Grunfeld, 2018</xref>). Seg&#x00FA;n <xref ref-type="bibr" rid="CIT046">Carter-Thuillier, L&#x00F3;pez Pastor, &#x0026; Gallardo Fuentes (2016)</xref> existen dos enfoques a la pr&#x00E1;ctica de AF con la aculturaci&#x00F3;n de los inmigrantes. Un primer enfoque que ve el deporte como un campo f&#x00E9;rtil para posibles conflictos culturales entre poblaciones. Muchas veces se asume que el deporte es un elemento socializador entre culturas y puede condicionar de forma negativa las relaciones entre grupos minoritarios (<xref ref-type="bibr" rid="CIT019">Barker et al., 2013</xref>). Otro enfoque que ve el deporte como una herramienta que favorece la integraci&#x00F3;n cultural entre las poblaciones. Las actividades deportivas favorecen la cohesi&#x00F3;n social entre las culturas promueven el respeto por el otro (<xref ref-type="bibr" rid="CIT122">K. C. W. Li, Sotiriadou, &#x0026; Auld, 2015</xref>). Los clubes deportivos a trav&#x00E9;s de la pr&#x00E1;ctica de AF deportivas, podr&#x00ED;an ser espacios que ayuden a la adquisici&#x00F3;n de capital social e integraci&#x00F3;n entre poblaciones inmigrantes y aut&#x00F3;ctonas. Programas deportivos comunitarios han demostrados ser herramientas importantes en los procesos de inclusi&#x00F3;n y aculturaci&#x00F3;n de las poblaciones inmigrantes (<xref ref-type="bibr" rid="CIT072">Forde, Lee, Mills, &#x0026; Frisby, 2015</xref>; <xref ref-type="bibr" rid="CIT190">Theeboom, Schaill&#x00E9;e, &#x0026; Nols, 2012</xref>).</p>

<title><bold>Programas y promoci&#x00F3;n de la Actividad F&#x00ED;sica</bold></title>
<p>Para frenar y limitar los efectos negativos del sedentarismo y la falta de AF, la OMS a trav&#x00E9;s del plan de acci&#x00F3;n mundial para la AF entre los a&#x00F1;os 2018 y 2030 (<xref ref-type="bibr" rid="CIT212">WHO, 2018</xref>) y de la estrategia para la AF en la regi&#x00F3;n de Europa entre <target target-type="page" id="pges_30"/>los a&#x00F1;os 2016 y 2025 (<xref ref-type="bibr" rid="CIT211">WHO, 2015</xref>) ofrece orientaciones, acciones y ayudas a los pa&#x00ED;ses para promover una AF regular como medida preventiva, para reducir los factores de riesgos de la inactividad f&#x00ED;sica en funci&#x00F3;n de la edad, del sexo, el origen &#x00E9;tnico y el nivel socioecon&#x00F3;mico de las personas. Para contribuir a esos objetivos, el entorno escolar desempe&#x00F1;a un papel importante en la promoci&#x00F3;n de la AF y sobre todo gracias a la asignatura de EF o la organizaci&#x00F3;n de programas o actividades extraescolares que promueven la pr&#x00E1;ctica de deportes, juegos y AF (<xref ref-type="bibr" rid="CIT010">Angawi &#x0026; Gaissi, 2021</xref>; <xref ref-type="bibr" rid="CIT043">Carlson et al., 2015</xref>; <xref ref-type="bibr" rid="CIT087">Hatfield &#x0026; Chomitz, 2015</xref>; <xref ref-type="bibr" rid="CIT126">Loprinzi, Cardinal, Loprinzi, &#x0026; Lee, 2012</xref>). Seg&#x00FA;n <xref ref-type="bibr" rid="CIT021">Bauman et al. (2012)</xref> es imprescindible tener en cuenta esos diferentes &#x00E1;mbitos de la AF (EF, deportes extraescolares, deporte en clubes, actividades de ocio, desplazamientos activos etc.) para la elaboraci&#x00F3;n y realizaci&#x00F3;n de programas orientados a la promoci&#x00F3;n de la AF especificados a los comportamientos de los j&#x00F3;venes, el contexto en general en el cual viven y en particular para los inmigrantes. A modo de ejemplo, la participaci&#x00F3;n en programas de AF organizada con control alimenticio ha mostrado efectos positivos para reducir los niveles de obesidad y sobrepeso en el &#x00E1;mbito escolar y educativo (<xref ref-type="bibr" rid="CIT031">Bj&#x00F8;rnar&#x00E5; et al., 2021</xref>; <xref ref-type="bibr" rid="CIT119">J. Lee, 2021</xref>). A nivel social, el deporte o la actividad f&#x00ED;sica puede favorecer la inclusi&#x00F3;n social de las personas en general y de los j&#x00F3;venes inmigrantes en particular (<xref ref-type="bibr" rid="CIT129">Makarova &#x0026; Herzog, 2014</xref>; <xref ref-type="bibr" rid="CIT150">M&#x00FC;ller &#x0026; Garc&#x00ED;a Jerez, 2013</xref>). Programas deportivos han demostrado que los j&#x00F3;venes inmigrantes que participan en programas extraescolares se integran m&#x00E1;s f&#x00E1;cilmente en la sociedad y con los j&#x00F3;venes aut&#x00F3;ctonos (<xref ref-type="bibr" rid="CIT072">Forde et al., 2015</xref>; <xref ref-type="bibr" rid="CIT102">Jim&#x00E9;nez Herranz, L&#x00F3;pez Pastor, &#x0026; Manrique Arribas, 2015</xref>; <xref ref-type="bibr" rid="CIT157">Okamoto, Herda, &#x0026; Hartzog, 2013</xref>). El deporte permite la transmisi&#x00F3;n de conductas y valores positivas a trav&#x00E9;s de la pr&#x00E1;ctica f&#x00ED;sica con diverso origen cultural (<xref ref-type="bibr" rid="CIT128">Madrid L&#x00F3;pez, Prieto-Ayuso, Samalot-Rivera, &#x0026; Gil Madrona, 2016</xref>), por lo que la pr&#x00E1;ctica f&#x00ED;sica se encuentra ser un pilar importante para la lucha contra las desigualdades y para la lucha contra el sedentarismo. Sin embargo, los programas deportivos en el &#x00E1;mbito escolar no pueden funcionar por si solos. Un reciente estudio cualitativo (<xref ref-type="bibr" rid="CIT192">Tibbitts et al., 2021</xref>) muestra que las intervenciones escolares a favor de la pr&#x00E1;ctica de AF no funcionan fuera de ella y a largo tiempo sin el apoyo de las comunidades locales (agentes pol&#x00ED;ticos) y el apoyo de los padres. Esa investigaci&#x00F3;n sugiere la implicaci&#x00F3;n de los agentes pol&#x00ED;ticos, los padres y los medios de comunicaci&#x00F3;n para tener consecuencias duraderas en el tiempo.</p>
<p>Por lo que no se puede olvidar de la asignatura de EF que promueve la AF, la transmisi&#x00F3;n de valores y la integraci&#x00F3;n social mediante acciones educativas. La EF es importante para la adquisici&#x00F3;n de h&#x00E1;bitos de vida activa y saludable (<xref ref-type="bibr" rid="CIT051">Consejer&#x00ED;a de Educaci&#x00F3;n, 2014</xref>). Para ello la pr&#x00E1;ctica deportiva tiene un papel importante para un desarrollo f&#x00ED;sico integral del alumnado. La EF contribuye a la educaci&#x00F3;n en el cuidado de la salud y de la seguridad a trav&#x00E9;s del conocimiento del propio cuerpo, tanto en horario de clase como <target target-type="page" id="pges_31"/>en los recreos (<xref ref-type="bibr" rid="CIT137">Mart&#x00ED;nez, Aznar, &#x0026; Contreras, 2015</xref>). Eso hace de la EF una herramienta imprescindible contra el sedentarismo y la adquisici&#x00F3;n de h&#x00E1;bitos saludables, a corto, medio y largo plazo en ni&#x00F1;os/as y j&#x00F3;venes (<xref ref-type="bibr" rid="CIT219">World Health Organization, 2020b</xref>).</p>
<p>En Espa&#x00F1;a la EF es asignatura obligatoria en la ense&#x00F1;anza primaria y secundaria. Su carga lectiva es de dos horas semanales en todos los niveles de ense&#x00F1;anza a la excepci&#x00F3;n de secundo de bachillerato donde no se imparte la asignatura de EF. La asignatura de EF tiene como &#x201C;finalidad principal desarrollar en las personas su competencia motriz, entendida como la integraci&#x00F3;n de los conocimientos, los procedimientos, las actitudes y los sentimientos vinculados sobre todo a la conducta motora&#x201D; (<xref ref-type="bibr" rid="CIT141">Real Decreto 1105/2014</xref>). Asimismo, la EF est&#x00E1; &#x201C;vinculada a la adquisici&#x00F3;n de competencias relacionadas con la salud, a trav&#x00E9;s de acciones que ayuden a la adquisici&#x00F3;n y consolidaci&#x00F3;n de h&#x00E1;bitos responsables de actividad f&#x00ED;sica regular y la adopci&#x00F3;n de actitudes cr&#x00ED;ticas ante pr&#x00E1;cticas individuales, grupales y sociales no saludables, fundamentalmente en lo relacionado con las enfermedades de origen cardiovascular&#x201D; (<xref ref-type="bibr" rid="CIT141">Real Decreto 1105/2014</xref>). En la Comunidad de Madrid, el peso horario es de dos horas semanales para la ense&#x00F1;anza obligatoria de segundaria (<xref ref-type="bibr" rid="CIT050">Decreto 59/2020</xref>). Tambi&#x00E9;n existe la posibilidad para los alumnos de 1&#x00B0;, 2&#x00B0; y 3&#x00B0; de la ESO de cursar dos horas m&#x00E1;s de EF si esos eligen como optativa la asignatura de Deporte, siempre que los centros escolares la propongan (Decreto 59/2020). En los centros incorporados a los estudios, tres de ellos ten&#x00ED;an como optativa la asignatura de deporte. Por lo que esos alumnos ten&#x00ED;an hasta cuatro horas semanales de EF.</p>

<title><bold>Justificaci&#x00F3;n de la tesis</bold></title>
<p>Debido a que la pr&#x00E1;ctica de la AF incluye numerosos factores que implican perspectivas personales; como el papel de la familia como mediador y referencia de adquisici&#x00F3;n de h&#x00E1;bitos y comportamientos, la influencia de las creencias, la etnia, la cultura, la religi&#x00F3;n, y el entorno social, dentro del barrio, y el medio escolar; es preciso realizar un estudio donde se describan y analicen las diferentes perspectivas de las familias y otros participantes de la comunidad sobre la pr&#x00E1;ctica de la AF.</p>
<p>Para ello, la metodolog&#x00ED;a utilizada deber&#x00ED;a ser cualitativa, que permite describir y analizar la perspectiva de grupo sobre determinados fen&#x00F3;menos bas&#x00E1;ndose en su perspectiva y experiencia sobre ese fen&#x00F3;meno (la pr&#x00E1;ctica de AF por sus hijos/as).</p>
<p>La presente tesis doctoral se ha focalizado en dar respuesta a esas preguntas a trav&#x00E9;s de 3 estudios. El primer estudio (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) se centra en <target target-type="page" id="pges_32"/>describir las barreras que encuentran los j&#x00F3;venes extranjeros a practicar AF a trav&#x00E9;s de la perspectiva de las familias, profesores, directores de la escuela y l&#x00ED;deres religiosos. El segundo estudio (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) describe la perspectiva de las familias de ni&#x00F1;os y j&#x00F3;venes que est&#x00E1;n en el medio escolar, y profundiza en las barreras y limitaciones a la pr&#x00E1;ctica de la AF. Finalmente, el tercer estudio (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) describe la perspectiva de los profesores que imparten EF en el medio escolar.</p>

<title><bold>Pregunta general de la tesis</bold></title>
<p>Es preciso se&#x00F1;alar que en las investigaciones cualitativas no existe hip&#x00F3;tesis de partida (ni nula, ni alternativa), debido a que no se pretende buscar la representatividad, ni la extrapolaci&#x00F3;n y/o generalizaci&#x00F3;n de los resultados (<xref ref-type="bibr" rid="CIT045">Carpenter &#x0026; Suto, 2008</xref>; Creswell, 2012). Se presenta la pregunta de investigaci&#x00F3;n que describe el &#x00E1;rea o &#x00E1;reas a indagar. En la presente tesis las preguntas que gu&#x00ED;an la investigaci&#x00F3;n fueron:</p>
<p>&#x00BF;Cu&#x00E1;l es el significado de la AF para las familias inmigrantes con hijos/as en el medio escolar? &#x00BF;Y para otros actores de su entorno como profesores, l&#x00ED;deres espirituales, directores de colegios? &#x00BF;Qu&#x00E9; barreras y facilitadores para realizar AF son percibidos por las familias de esos ni&#x00F1;os/as?</p>

<title>Abstract:</title>
<p>Physical activity facilitates the acquisition of healthy habits from childhood to adulthood. Differences exist regarding the performance of physical activity among immigrant children compared to native Spanish children. The purpose of the study was to describe the barriers that exist for the promotion of physical activity. A qualitative case-study approach was implemented. Parents of immigrant children, teachers, a school principal, and priests were included, using purposeful sampling. Data were collected from 25 participants, via unstructured and semi-structured interviews, focus groups, and researchers&#x2019; field notes. A thematic analysis was performed and ecological levels were identified. Our findings revealed the following barriers to performing physical activity: (a) the meaning of physical activity, (b) gender inequalities, (c) academic burden, (d) lack of social contact, (e) expenses and family economy, (f) lack of infrastructure and natural surroundings, (g) time constraints, (h) fear and insecurity, and (i) the reason for immigrating. These results may be used to revise the school curriculum, promoting equal opportunities for physical activity and encouraging family participation. Additionally, urban design policies should be encouraged to facilitate access to open spaces for recreation within cities.</p>

<title><bold>Introduction</bold></title>
<p>Physical inactivity is considered the fourth leading risk factor for global mortality [<xref ref-type="bibr" rid="ref.3.1">1</xref>]. On a global level [<xref ref-type="bibr" rid="ref.3.2">2</xref>], more than 80% of school age youth are physically inactive. More specifically, in Spain, gender differences have been documented, with girls being overall less active than boys (16.3% vs. 8.2%) [<xref ref-type="bibr" rid="ref.3.3">3</xref>,<xref ref-type="bibr" rid="ref.3.4">4</xref>]. To counteract this problem, regular physical activity is recommended as it provides numerous health benefits, such as reductions in hypertension, coronary heart disease, type 2 diabetes, breast cancer, and stroke [<xref ref-type="bibr" rid="ref.3.5">5</xref>]. Additionally, physical activity improves body weight control and promotes muscle and joint functioning [<xref ref-type="bibr" rid="ref.3.5">5</xref>], improves concentration, and enhances children&#x2019;s school performance [<xref ref-type="bibr" rid="ref.3.6">6</xref>,<xref ref-type="bibr" rid="ref.3.7">7</xref>].</p>
<p>A number of factors have been shown to influence physical activity levels in children and adolescents. These include the school environment, immigration, culture, and the social and community context where the child lives [<xref ref-type="bibr" rid="ref.3.8">8</xref>-<xref ref-type="bibr" rid="ref.3.13">13</xref>]. The school environment plays an important role in the promotion of physical activity, thanks to physical education and the organization of after school activities that promote the practice of sports, games, and other physical activities [<xref ref-type="bibr" rid="ref.3.7">7</xref>,<xref ref-type="bibr" rid="ref.3.11">11</xref>,<xref ref-type="bibr" rid="ref.3.14">14</xref>]. In Spain, <target target-type="page" id="pges_37"/>the 2012 national health survey [<xref ref-type="bibr" rid="ref.3.4">4</xref>] documents differences between people who were born in Spain and those who were born abroad but subsequently immigrated to Spain. For people over the age of 15, 43.8% of those born in Spain (i.e. the native population) were sedentary, compared to 48.3% of people born abroad (i.e. the immigrant population) [<xref ref-type="bibr" rid="ref.3.4">4</xref>]. This finding is supported by previous studies [<xref ref-type="bibr" rid="ref.3.9">9</xref>,<xref ref-type="bibr" rid="ref.3.10">10</xref>] that show that children of foreign parents are less physically active.</p>
<p>Ethnicity and culture are important determinants with regard to the performance of physical activity in immigrant children. In a study of multi-ethnic parents&#x2019; views of children&#x2019;s physical activity in North West England, Trigwell et al. [<xref ref-type="bibr" rid="ref.3.10">10</xref>] reported that on an environmental level, barriers to physical activity included safety concerns, and both a lack of resources and lack of access. Additional barriers were noted for ethnic groups with a Muslim faith (Asian Bangladeshi, black Somali, Yemeni), who reported a lack of culturally appropriate physical activity opportunities for girls. In addition, the perspective of immigrant parents regarding physical activity may condition the performance of the same in their children. For example, parents can positively influence their offspring and act as role models, by providing emotional support, economic resources (covering expenses), and by providing transportation with their car [<xref ref-type="bibr" rid="ref.3.7">7</xref>,<xref ref-type="bibr" rid="ref.3.12">12</xref>]. In contrast, parents may also limit their child&#x2019;s physical activity when they perceive that insufficient safety conditions are available for the performance of physical activity [<xref ref-type="bibr" rid="ref.3.7">7</xref>,<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.13">13</xref>], or when they feel that the curricular content of the child should be oriented towards mental-cognitive training as opposed to physical education [<xref ref-type="bibr" rid="ref.3.15">15</xref>].</p>
<p>Where an immigrant child lives also impacts their level of physical activity. Aspects such as the presence of a means of transport, sports centers, the level of safety and crime in the neighborhood and the presence of parks are all relevant when performing physical activity, via games and sports, and/or allowing children to walk to school on their own [<xref ref-type="bibr" rid="ref.3.7">7</xref>,<xref ref-type="bibr" rid="ref.3.12">12</xref>,<xref ref-type="bibr" rid="ref.3.15">15</xref>]. Lin et al [<xref ref-type="bibr" rid="ref.3.16">16</xref>], in their study about neighborhood social environments and children&#x2019;s independent mobility, described how children with parents who perceived their neighborhood as being safe and more cohesive, and who lived closer to their child&#x2019;s school, were more likely to allow them to travel to school unaccompanied. For New Zealanders, European, Maori, Samoan, and other Pacific parents in Australia [<xref ref-type="bibr" rid="ref.3.16">16</xref>], and also for Asian minority parents in London, and Turkish minority parents in Germany [<xref ref-type="bibr" rid="ref.3.17">17</xref>], security, danger, and crime were common concerns that impacted allowing their children to go out alone.</p>
<p>However, these aforementioned factors do not act independently of each other. Indeed, certain environments (social and physical environments) and policies, can make a community and its environment either more favorable or more adverse toward the promotion of physical activity [<xref ref-type="bibr" rid="ref.3.18">18</xref>]. To better understand this relationship between individual and environmental factors, ecological models [<xref ref-type="bibr" rid="ref.3.18">18</xref>] focus on the relationship between people and their physical and sociocultural environments and show that environmental contexts are predictors of health behaviors, such as physical activity [<xref ref-type="bibr" rid="ref.3.18">18</xref>]. Ecological models incorporate a wide range of influences at multiple levels. Levels of variables or dimensional studies included in ecological models of physical activity include intrapersonal (biological, psychological), interpersonal/cultural, organizational variables, or those related to the physical environment (built, natural), and policy (laws, rules, regulations, codes) [<xref ref-type="bibr" rid="ref.3.18">18</xref>]. Ecological models are particularly useful in assisting research and practice when applied to a specific behavior since unique environmental and policy factors may influence each behavior [<xref ref-type="bibr" rid="ref.3.2">2</xref>]. Ecological models identify factors and design interventions to influence multiple levels, including individuals, social environments, organizations, built environments, and policies, in order to achieve population improvements in public health [<xref ref-type="bibr" rid="ref.3.18">18</xref>].</p>
<p>Despite accumulating evidence of factors that promote physical activity among immigrant children, there is little research on the parents&#x2019; perspective and that of other physical activity stakeholders (teachers, community leaders). In Spain, a gap exists in the identification of barriers and/or difficulties for the promotion of physical activity, both from the parents&#x2019; perspective and that of the members of the social and community environment, such as teachers, school principals, and social community leaders.</p>
<p><target target-type="page" id="pges_38"/>The purpose of our study was to describe barriers for the promotion of physical activity, perceived by parents, teachers, a school principal, and social community leaders. The question that guided our study was: What barriers do parents and teachers encounter when promoting physical activity among recently immigrated children who face a new cultural context?</p>

<p>This study was conducted in the city of Alcorc&#x00F3;n (Madrid, Spain), with a population of 175,000 inhabitants in the year 2017. The reported immigrant population rate of Alcorc&#x00F3;n was 11.9% in 2017, compared to an average 13% in the community of Madrid [<xref ref-type="bibr" rid="ref.3.27">27</xref>]. The reported population of children between four and 15 years of age in 2014 was 17,765, of which 1,883 were foreigners, representing 10.5% of the child population. We reached a consensus to include participants from two contexts: (a) the school environment, by including two educational centers (EC) from Alcorc&#x00F3;n; and (b) the social-community environment via the inclusion of two Catholic parishes (CP) of Alcorc&#x00F3;n.</p>

We contacted two EC and 10 teachers who taught children between 10&#x2013;14 years of age, along with the school principal. They put us in touch with parents who met the inclusion criteria, of whom five agreed to participate in the study. Additionally, contact was made with the principals of two CP, who put the researchers in touch with immigrant parents who met the inclusion criteria, of whom seven agreed to participate in the study. Also, two priests who directed activities for the promotion of sports and cultural activities with the immigrant families agreed to participate in the study.

<p>This study was approved by the Clinical Research Ethics Committee of the University Rey Juan Carlos (Project identification code: 3001201702417). The study was conducted in accordance with the principles articulated in the WMA Declaration of Helsinki (Ethical Principles for Medical Research Involving Human Subjects). Furthermore, we followed the Spanish Personal Data Protection Act and the Biomedical Research Act [<xref ref-type="bibr" rid="ref.3.32">32</xref>].

<title><bold>Results</bold></title>
<p>Twenty-five participants were included in the study with a mean age of 43.4 &#x00B1; 8.7 years. See <xref ref-type="table" rid="c3-s1-tab1">Table 1</xref> for the sociodemographic profile of the participants. The teachers and the principal had 16.6 &#x00B1; 8.4 years of teaching experience. The country of birth of the respective parents was Peru (4), Colombia (2), Ethiopia (1), Venezuela (1), Guatemala (2), and Senegal (2). The themes representing the participants&#x2019; experiences were extracted from the unstructured interviews, FGs, and semi-structured interviews. Nine themes emerged from the material analyzed: (a) the meaning of physical activity, (b) gender inequalities, (c) academic burden, (d) lack of social contact, (e) expenses and family economy, (f) lack of infrastructure and natural surroundings, (g) time constraints, (h) fear and insecurity, and (i) the reason for immigrating. We included the narratives taken directly from the data collection regarding the themes identified in this study.</p>
<p>Within the findings, the multilevel ecological model by Sallis et al. was used [<xref ref-type="bibr" rid="ref.3.18">18</xref>] to identify the most relevant levels of the model within the themes that were obtained. A summary of the levels of the ecological model is featured in <xref ref-type="table" rid="c3-s1-tab6">Tables 6</xref>-<xref ref-type="table" rid="c3-s1-tab14">14</xref>.</p>

<title><italic>The Meaning of Physical Activity</italic></title>
<p>One of the barriers found was related to the different perspectives concerning physical activity. For teachers, physical activity was considered part of a child&#x2019;s education and linked to their relationship with their body, highlighting the need for children to acquire healthy habits through learning: &#x201C;It is impossible to understand the education of these recently arrived children by separating the mental aspects from the physical ones. The body and the child&#x2019;s relationship with their body should be a priority for providing healthy habits.&#x201D; (teacher, focus group). Additionally, for parents, physical activity included movement, agility, physical space, the natural environment, and playing. Physical inactivity was associated with keeping the children locked up indoors: &#x201C;The children live in cages, they are locked up, it is necessary to get them out of there&#x201D; (mother, interview). Finally, the priests <target target-type="page" id="pges_43"/>described how the children must perform activities together with the family, promoting family union as a key pillar of the community.</p>
<p>The participants perceived a decrease of physical activity in terms of sports and/or games. The absence of games and/or informal extracurricular activities was identified as a barrier for physical activity. The parents described the importance of games that children perform outdoors (i.e., in the street, as being an informal way to perform physical activity). They compared this with their countries of origin, and described how, in Spain, children spend more time at home: &#x201C;Here, it seems like they aren&#x2019;t children. They are in their home, playing with the computer, the mobile phones, they are disconnected from playing, from activity, from movement, from their childhood&#x201D; (father, interview). Many times, parents and teachers concurred that movement via playing should be assigned more importance than intellectual educational pursuits: &#x201C;They need to peel away from the chair and not only work with their brain, although this is also important&#x201D; (teacher, interview). The levels of the ecological model identified are described in <xref ref-type="table" rid="c3-s1-tab6">Table 6</xref>.</p>

<title><italic>Gender Inequalities</italic></title>
<p>Gender differences can represent a barrier to the performance of physical activity. Most participants narrated that no difference should exist between boys and girls and that all children should be free to select and practice their preferred activity. However, according to many parents, in real life, there was a difference. These differences existed in their countries of origin and were maintained in Spain: &#x201C;Soccer is practiced by boys. There are more and more girls, but it is a boy thing. Over there, girls practice volleyball and rhythmic gymnastics. It is very rare for girls to practice it&#x201D; (father, interview).

<title><italic>Academic Burden</italic></title>
<p>The extensive activities children perform at school in addition to homework were perceived as a barrier by parents and teachers. The school day, together with homework to be done after classes, was perceived to lead to children who were continuously tired, stressed, and who lacked time for other activities. All the parents described how the school gave more importance to time dedicated to the educational content than time dedicated to leisure. Because of this, the time dedicated to homework was a hindrance for the practice of physical activity during after-school hours: &#x201C;They have a large theoretical burden, they must study and they don&#x2019;t want to do anything else. The excessive amount of homework prevents them from playing and doing sports and having fun&#x201D; (father, focus group). &#x201C;The educational system doesn&#x2019;t let the child be a child. If the school timetables were better organized, then they could have more time to play&#x201D; (mother, interview).</p>
<p>This point of view was shared by the teachers, who acknowledged that the homework burden should be decreased after school, and that the practice of other activities that allow children to &#x201C;move&#x201D; and &#x201C;wake up their body&#x201D; should be facilitated: &#x201C;All day long they are confined to the classroom, and when they go home, they have to do their homework. When are they really children? When do they have time to jump, run, play among themselves, compete, or train any kind of sport? We are focusing on their brain and we forget that they are in a physical body which, if we do not teach them to care for it, when they become adults, they will have problems.&#x201D; (teacher, interview).</p>
<p>This contrasted with the point of view of the director, who felt that children must face a social and educational environment, which demands them to acquire knowledge and performance, and the school is responsible for preparing them for this: &#x201C;I understand that children should play more, but, the truth is that in a few years they have to face tests and social demands. It is also our role as educators to prepare them as best as possible&#x201D; (principal, interview).

<title><target target-type="page" id="pges_45"/><italic>Lack of Social Contact</italic></title>
<p>Participants described how contact with other native children facilitates their ability to relate with others via play and physical activity: &#x201C;It is very important that they practice physical activity, to relate with others ( &#x2026; ) they share things with school friends and they teach new things to their adopted country&#x201D; (mother, interview). The teachers described how immigrant children have more difficulty interacting with native children (because they do not know the language, because of rejection, or not understanding the instructions, etc.), and participating in physical activity, therefore choosing more sedentary activities: &#x201C;The less contact they have with other children, the more closed they become and they participate less in other activities and games. It&#x2019;s a vicious circle.&#x201D; (teacher, focus group). On the other hand, most participants agreed that physical activity in a group can help children establish a better connection with the class, with the school and the new country: &#x201C;I would take away many of the classes and reinforce physical activity for newly arrived immigrant children. Movement is a way for them to communicate among themselves, it&#x2019;s innate, it&#x2019;s natural.&#x201D; (teacher, interview).</p>
<p>In the construction of relationships, relatives who are believers go to church, where they share experiences, and where immigrant children have contact with other children and with Spanish families. Church worship is an opportunity to establish contact and acquire local customs: &#x201C;Our role is to try and make them feel like they have a place in our family [the church]. Besides, we help them to understand our customs, we organize activities so that they begin to meet new families, so that they can integrate faster.&#x201D; (priest, interview). &#x201C;When we got to Spain we were disoriented, the language was the same, but we did not understand many things, here [in Spain], people behave differently, there are other ways of doing things. The church helped us to feel that we belonged somewhere. For my children, it helped them a lot because the first thing they remember is going to the camp that the church organized. They are still friends with the children they met there.&#x201D; (father, interview).</p>

<title><italic>Expenses and Family Economy</italic></title>
<p>One of the barriers is the economic costs families face when their children practice some kind of organized physical activity. The parents described how this is an expense that they cannot afford: &#x201C;If you want [your child to practice sports] you have to pay and that is an expense that I cannot afford.&#x201D; (father, interview). The parents described how, in their countries, there are many social subsidies for playing sports and performing physical activity: &#x201C;There are associations that give you free sports <target target-type="page" id="pges_46"/>training. On behalf of the town hall there are also sports centers, and everything is free&#x201D; (mother, interview). The parents and teachers described the economic sacrifice the family must make in order for them to practice an activity in Spain: &#x201C;I know many friends who must go to great efforts so that their sons practice soccer.&#x201D; (mother, interview). This sacrifice takes many forms, such as investing considerable time, facing economic expenses to cover trips, sports equipment, and enrollment fees in the sports center.

<title><italic>Lack of Infrastructure and Natural Surroundings</italic></title>
<p>The teachers and parents related that the absence of sports and leisure infrastructure influences the practice of physical activity: &#x201C;Our city seems like an abandoned town. There is no place to do sports. There&#x2019;s not even a sports field, or a sports center to take them to.&#x201D; (mother, focus group). Also, the parents associated the lack of physical activity with the excessive distance and/or poor accessibility of the space. Many of the parents lacked their own vehicle, having to use public transport as an alternative, or they lacked resources to reach the sports centers: &#x201C;I would like to take my son to training every day, but we don&#x2019;t have a car. And to think of using public transport, with the amount of buses that I would have to take to get there, makes it unfeasible. It&#x2019;s better if he stays at home and studies other subjects.&#x201D; (mother, focus group).</p>
<p>Many parents described that to share physical activity and games in nature with their children, they must cover long distances. Access to nature is also difficult, whereas in their countries it was part of their daily life: &#x201C;In my country there were no parks, we had no need, nature was all around the house. Children were playing in the trees all day long. Getting to know &#x2018;nature&#x2019; was not an extra activity necessary for their education. They lived with it.&#x201D; (father, focus group).

<p>Parents lacked enough time to share activities with their children because of a work timetable that was incompatible with the children&#x2019;s leisure time. The workdays were long and prevented them from playing with their children outside of the home (park) or taking them to sports practices: &#x201C;Work influences a lot, you aren&#x2019;t with them enough [the children].&#x201D; (mother, interview). &#x201C;First things first, and that means working to be able to give my children an opportunity to continue forward in a new country. Games and sports, although it pains me to say it, will have to wait.&#x201D; (father, focus group). From the point of view of the teachers, the organization of the child&#x2019;s day hampered the practice of physical activity, as it coincided with the parents&#x2019; workday: &#x201C;The extracurricular activities have timetables that are not compatible with the timetables of their parents, which are workdays of 10-14 hours each day (teacher, interview).

<title><italic>Fear and Insecurity.</italic></title>
<p>Perceived fear and insecurity were other hindrances for practicing physical activity. Some parents even used the term &#x201C;terror&#x201D; to describe their feeling of insecurity when taking their children to perform physical activity or play outdoors. They felt that it was unsafe to leave children alone playing on the street: &#x201C;I am terrified about taking them to the park to play basketball. There is a big park, but it <target target-type="page" id="pges_48"/>has a bit of everything and you see people who are so strange, it&#x2019;s scary. And in the street the same thing happens, I don&#x2019;t let them go out on their own.&#x201D; (mother, interview). Some parents demanded the need for open spaces, such as parks; however, over time, many acknowledged that they stopped going to these places with their children due to feelings of insecurity: &#x201C;I know that my children need to run, jump, play, practice sports and leave the home &#x2026; but if the alternative is playing soccer in a neighborhood that I don&#x2019;t know, or in the park with no control, I prefer that they stay at home.&#x201D; (father, focus group).</p>
<p>In contrast, there were participants who felt that risks always exist, and therefore this must not condition children to limit their opportunities of doing sports, playing or interacting with other children and in other environments. They compared how, in their countries of origin, this risk was much more palpable, and that in Spain, children must not stop practicing sports because the risk is very different: &#x201C;In my country [Columbia], there is a lot of crime. You can&#x2019;t do anything in the open air. You know, kidnappings, armed assault and those kinds of things. In Spain, you go out running and you aren&#x2019;t fearful of people robbing you, here you do not perceive any insecurity.&#x201D; (mother, interview).

<title><italic>The Reason for Immigrating.</italic></title>
<p>The reasons that lead the families to immigrate can also be a hindrance for children to practice physical activity. For many parents, economic reasons were behind their choice to immigrate. Therefore, practicing physical activity was not seen as a priority: &#x201C;What did we come here for (the immigrants): to work and make money, and we don&#x2019;t have time to do anything more, the rest is secondary, my children understand.&#x201D; (father, interview). On the other hand, when residence was more permanent (refugees, political asylum), the children&#x2019;s education, with all its intellectual and physical dimensions, acquired greater importance. Children were prioritized and therefore required parents&#x2019; time: &#x201C;When you realize that Spain is going to be your new home, everything changes. You try to give your children the same opportunities as any other child, for him to do what other children here [in Spain] do, to become one of them. His education is the most important thing.&#x201D; (mother, focus group). The levels of the ecological model identified are described in <xref ref-type="table" rid="c3-s1-tab14">Table 14</xref>.</p>

<p>Our results revealed a number of barriers for physical activity promotion in immigrant children from the perspective of parents, teachers, a principal, and community leaders. Our study continues a line of research on the factors that impact upon and influence the practice of physical activity and the implementation of a healthy lifestyle in immigrant children [<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.17">17</xref>,<xref ref-type="bibr" rid="ref.3.22">22</xref>].</p>
<p>Previous studies regarding physical activity in children and teenagers [<xref ref-type="bibr" rid="ref.3.33">33</xref>,<xref ref-type="bibr" rid="ref.3.34">34</xref>] show how children and teenagers whose parents were immigrants practiced less physical activity compared to native children and teenagers. In the USA, Brewer et al [<xref ref-type="bibr" rid="ref.3.33">33</xref>] reported that this disparity is not attenuated by a child&#x2019;s socioeconomic, family, or neighborhood characteristics. Also, patterns of physical activity have been found to vary according to the immigrant generation status (being born in a new country vs. being born in the country of origin), and the process of acculturation [<xref ref-type="bibr" rid="ref.3.33">33</xref>,<xref ref-type="bibr" rid="ref.3.34">34</xref>].</p>
<p>Our participants did not agree with the existence of gender inequality in the practice of physical activity; however, many parents acknowledged that this type of bias exists in their country of origin. The existence of inequality in the practice of physical activity among men and women can be considered a global phenomenon [<xref ref-type="bibr" rid="ref.3.35">35</xref>]. In Spain, the 2016 survey on sports habits by the Ministry of Education and Culture [<xref ref-type="bibr" rid="ref.3.36">36</xref>] shows that boys mostly practice sports such as soccer, cycling, and swimming, and that girls mainly practice gymnastics, hiking, and swimming. Previous studies [<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.37">37</xref>] show that this gender difference exists even in recess hours during school, where the amount of physical activity performed varies (greater in boys) as well as the type of activities performed (&#x201C;boys games&#x201D; versus &#x201C;girls games&#x201D;). Culture, ethnicity, and religion may, in part, explain this gender difference in immigrant children [<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.37">37</xref>].</p>
<p>Our participants perceived a significant academic burden regarding academically-oriented school activities compared to activities promoting physical skills. This is in line with Trigwell et al. [<xref ref-type="bibr" rid="ref.3.10">10</xref>], who reported that ethnic groups from different cultures (Asian Bangladeshi, Chinese, Yemeni) prioritized educational attainment over physical activity. In contrast, many studies [<xref ref-type="bibr" rid="ref.3.14">14</xref>,<xref ref-type="bibr" rid="ref.3.38">38</xref>] agree with the need to increase physical activity in school curricula [<xref ref-type="bibr" rid="ref.3.38">38</xref>] and incorporating break periods between lessons [<xref ref-type="bibr" rid="ref.3.14">14</xref>]. Public health recommendations highlight the pivotal role that schools and teachers play in providing equitable opportunities for physical activity for all children. Also, opportunities to increase physical activity throughout the school day should span, not only in-school time (e.g., quality recess and physical education, classroom activity breaks), but also time before school (e.g., active commuting initiatives) and after school (e.g., intramural and interscholastic sports programs) [<xref ref-type="bibr" rid="ref.3.11">11</xref>,<xref ref-type="bibr" rid="ref.3.38">38</xref>].</p>
<p>Our results highlight how the neighborhoods where our participants lived do not present the necessary conditions, nor do they have sufficient infrastructure, for the practice of physical activity. Previous studies [<xref ref-type="bibr" rid="ref.3.17">17</xref>,<xref ref-type="bibr" rid="ref.3.39">39</xref>] show how the neighborhood, the area of the city where they are located, the presence of parks, accessible urban transport, and comprehensive urban planning to support physical activity (walkability) all influence the performance of physical activity. More specifically, in the case of children and youth, previous studies [<xref ref-type="bibr" rid="ref.3.17">17</xref>,<xref ref-type="bibr" rid="ref.3.40">40</xref>] have shown an association between neighborhood-built environments and an increased level of physical activity (and, consequently, a decrease in sedentary time). This also applies to young immigrant children/youth of other cultures or ethnicities in Western countries [<xref ref-type="bibr" rid="ref.3.17">17</xref>].</p>
<p>Nevertheless, fear and insecurity are also major barriers for the practice of physical activity. Previous studies show how crime, insecurity, the perceived presence of &#x201C;dangerous&#x201D; people, and the lack of safe spaces influence the possibility of taking children to leisure activities in safe spaces (with or without physical activity) [<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.13">13</xref>,<xref ref-type="bibr" rid="ref.3.16">16</xref>,<xref ref-type="bibr" rid="ref.3.17">17</xref>].</p>
<p>Previous studies [<xref ref-type="bibr" rid="ref.3.12">12</xref>,<xref ref-type="bibr" rid="ref.3.41">41</xref>] have examined the influence of parents on children&#x2019;s physical activity, and the evidence for the context-specific influence of parental modelling on physical activity in childhood remains inconclusive. Along these lines, the SOPHYA Study Group [<xref ref-type="bibr" rid="ref.3.41">41</xref>] reported that parental modelling (physical activity practice) seems relevant for children&#x2019;s physical activity (p &#x003C; 0.001), and were stronger for children aged 10-12 years, although not to the same extent in all children. This conflicts with previous studies [<xref ref-type="bibr" rid="ref.3.12">12</xref>] which have shown that parental modeling was not associated <target target-type="page" id="pges_52"/>with physical activity in children. We believe that an important barrier in the practice of physical activity in immigrant children is the socioeconomic-work situation of the parents, narrated in the themes &#x201C;costs and economy,&#x201D; &#x201C;lack of time,&#x201D; and the &#x201C;motive for immigrating.&#x201D; Parents choose to immigrate in order to earn a living and improve the family&#x2019;s quality of life (via precarious employment or low-skilled employment with long working days), which is associated with insufficient economic resources and a lack of time for parents to invest in their children practicing physical activity, playing, and spending time together. Thus, a vicious circle is created, which can perpetuate certain activity routines in children in favor of sedentarism. In Spain, the National Immigrant Survey [<xref ref-type="bibr" rid="ref.3.42">42</xref>] describes how Latin American immigrants are labeled as economic immigrants (seeking economic improvements) who perform poorly qualified labor, and are mainly located in the lower levels of the socio-economic scale. Two out of every five immigrants are employed in manual labor and are poorly qualified (40%) and one in four (22%) performs manual labor for which a certain level of preparation is required. This means that low-skilled jobs with low salaries are perpetuated with long work days. Previous studies [<xref ref-type="bibr" rid="ref.3.22">22</xref>,<xref ref-type="bibr" rid="ref.3.40">40</xref>] show how parents&#x2019; lack of time, long work days, family burden, low salaries, and not having enough money to cover expenses (buying sports equipment, enrolling in sports activities) negatively impacts children&#x2019;s physical activity. According to former studies conducted in Spain [<xref ref-type="bibr" rid="ref.3.40">40</xref>,<xref ref-type="bibr" rid="ref.3.43">43</xref>], children and adolescents who live in neighborhoods with a lower socio-economic status are less physically active.</p>
<p>In Spain, previous studies [<xref ref-type="bibr" rid="ref.3.44">44</xref>,<xref ref-type="bibr" rid="ref.3.45">45</xref>] that took place in the cities of Granada and Cuenca described how the volume of traffic, the poorly signposted intersections and pedestrian crossings en route to the school, and the insecurity were perceived as barriers for the performance of physical activity in children. Additionally, the organization of space, time, and physical activity performed in recess time at school was highlighted [<xref ref-type="bibr" rid="ref.3.44">44</xref>]. The lack of programming any physical activity during recess time led to situations where only certain physical activities were performed, monopolizing time and space, meaning that, at times, children did not participate in any physical activity and that gender differences between boys and girls was perpetuated. An example of this is soccer playing. Guti&#x00E9;rrez-Zornoza et al. [<xref ref-type="bibr" rid="ref.3.45">45</xref>] described the influence of the environment on the physical activity habits of school children. These authors reported that children perceived that residing in gated communities or in rural areas facilitated physical activity, as opposed to residing in neighborhoods and cities. They reported that their children&#x2019;s feelings of insecurity regarding road traffic, car journeys, and an overall sense of not belonging or being accepted in the neighborhood were perceived as barriers to being active. Therefore, in Spain, the following barriers are highlighted: environmental barriers (accessing the schools and safe traffic), organizational barriers in the selection of physical activities within and outside the school, and social barriers (belonging to certain neighborhoods or areas). In previous Spanish studies [<xref ref-type="bibr" rid="ref.3.44">44</xref>,<xref ref-type="bibr" rid="ref.3.45">45</xref>], no distinction was made between immigrant and native children. On the other hand, within the context of Hispanic culture, in the USA, Ross and Francis [<xref ref-type="bibr" rid="ref.3.46">46</xref>] described physical activity perceptions, context, facilitators, and barriers from the perspective of Hispanic immigrant-origin children. These authors reported how Latino children had negative attitudes toward physical activity that were related to physical discomfort, low athletic competence, and safety concerns. Also, children had difficulties differentiating physical activity and play, and &#x201C;fun&#x201D; was identified as a primary driver of physical activity preferences. Also, Turner et al. [<xref ref-type="bibr" rid="ref.3.47">47</xref>] researched family lifestyle behaviors of Mexican-American and Mexican immigrant fathers and mothers and their repercussion on the performance of physical activities in children. This previous study found that parents were permissive regarding their child&#x2019;s sedentary habits (which involved playing video games and watching television for lengthy periods), rather than actively encouraging them to be more physically active.</p>
<p>In our study, one might expect that immigrants who have a common language, and a common Hispanic culture (nine parents), would not encounter difficulties for promoting physical activity in their children. However, we have found similar difficulties in previous studies [<xref ref-type="bibr" rid="ref.3.10">10</xref>,<xref ref-type="bibr" rid="ref.3.16">16</xref>,<xref ref-type="bibr" rid="ref.3.17">17</xref>,<xref ref-type="bibr" rid="ref.3.22">22</xref>] that studied physical activity in children of different ethnicities, cultures, religions, and languages. This could be explained by the fact that the socioeconomic conditions for the immigrant parents of our study <target target-type="page" id="pges_53"/>are perceived as a determinant for their children regarding performing physical activity, despite not having linguistic barriers. Additionally, during the process of integration, non-native children may acquire habits and customs of the new country that could influence their health, including the adoption of sedentary habits [<xref ref-type="bibr" rid="ref.3.48">48</xref>].</p>
<p>It is worth noting that ecological model proposed by Sallis [<xref ref-type="bibr" rid="ref.3.18">18</xref>] was a secondary analysis applied just to contextualize the results by classifying them. However, this ecological model was not the aim of this study despite being used with an exploratory purpose. On the other hand, this ecological model could be useful as a theoretical model to guide data collection and as a primary analysis of future qualitative studies in the field of physical activity.</p>
<p>The implications of this study are based on the development of specific policies, programs, and actions for fostering and promoting physical activity, as well as eliminating the associated barriers and difficulties present in the community, the school, and the homes of immigrant children and their families. These interventions must be open and acting simultaneously upon different levels. Thus, for example, the development of security policies and crime control in the physical environment (i.e., parks) of a community acts upon the levels of the policy environment, setting: access and characteristics, and perceived environment. More concretely, educational policies should be included, oriented towards improving physical education in schools, policies promoting physical activity in the community, and the use of public spaces with the development of programs oriented toward the integration of immigrant children via physical activity, policies that help immigrant families with limited resources to access infrastructures and sports resources, and finally, work policies that facilitate work timetables compatible with the leisure time of both the child and the family (policy environment level, social cultural environment level, setting: access and characteristics level, perceived environment level, and intrapersonal level). Besides, there is a need to develop programs in schools to promote equality among sexes for participation in physical activities and sports while supporting physical activity in the natural environment and open spaces (i.e., parks and forest). Likewise, it is necessary to include community initiatives that facilitate the use of leisure time outside the home for performing physical activity with other children and/or with the family. Lastly, detailed information should be provided concerning physical activity proposals by integrating public and private initiatives within the community (social cultural environment level, natural environment, information environment level, setting: access and characteristics level, behavior active living domains level, perceived environment level, and intrapersonal level). Besides, it is also important to encourage urban design policies that facilitate access to open spaces within and/or close to the communities, and the development of sports resources with accessible timetables that are compatible with the workload of parents. Also, a network of appropriate means of transport should be created to ensure access to sports centers (setting: access and characteristics level, social cultural environment level, behavior active living domains level, and intrapersonal level).</p>
<p>Future lines of research should study the existence of barriers for the practice of physical activity in immigrant children of different nationalities, focusing also on different sports and including girls from different cultures and ethnicities. Additionally, further research should aim to develop public policies to promote physical activity in immigrant children in urban settings.</p>

<title><italic>Limitations</italic></title>
<p>This study has several limitations. First, a small number of participants was included. The qualitative nature of this study meant that the aim was to describe the experiences of the participants and, therefore, these findings cannot be generalized. We also only included participants from a single religious context (i.e., Catholicism). It would be necessary to develop future studies with immigrants from other religions.</p>

<title><target target-type="page" id="pges_54"/><bold>Conclusions</bold></title>
<p>Our findings help further our understanding of the factors related with physical activity in immigrant children living in Spain. One of the strengths of this study is that this is the first study to describe the barriers for performing physical activity in immigrant children from the parents&#x2019; perspective and that of other participants living in their community and social environment.</p>
<p>Despite the fact that most parents in our study came from countries with cultural and linguistic ties with Spain, they perceived barriers for the performance of physical activity that were similar to the barriers identified in immigrants without cultural or linguistic ties to other European countries.</p>
<p>These results may be used for the development of physical activity programs in specific social contexts. These programs should: (a) reorganize the school study plans (decreasing the educational burden and the amount of homework given to children to increase the time dedicated to physical activity), (b) promote the participation of the whole family in children&#x2019;s physical activity, (c) provide economic support for families with fewer resources in order to cover enrollment costs and expenses related to children&#x2019;s sports practice, (d) improve the organization of sports activities and multicultural games in the community on behalf of the town halls and public institutions, and (e) encourage the development of safe natural public spaces within cities.</p>
<p>Future studies should incorporate the perspective of Spanish children and adolescents of immigrant origin to provide a greater depth to the development of physical activity programs and to further understand detected barriers and facilitators for the performance of physical activity.</p>

<title><target target-type="page" id="pges_59"/>Abstract:</title>
<p>Physical activity facilitates the acquisition of healthy habits from childhood to adulthood. There are differences in the practice of physical activity between immigrant children and native Spanish children. The aim was to describe physical activity in children, from the perspective of South American immigrant parents. A qualitative case study was conducted. Parents were recruited using purposeful sampling. Data were collected from 12 participants by means of unstructured interviews together with researcher notes. A thematic analysis was applied. The following topics were identified: (a) physical activity and health, (b) socialization, (c) the need for movement, (d) gender, (e) barriers, (f) educational burden, (g) community living, and (h) reason for immigrating. Parents described how physical activity is fundamental and has benefits for health, and for the relationship between children. They perceived that physical activity should not be limited by gender. The time dedicated to other school activities, the norms related to community living, and financial limitations were especially relevant as barriers for the performance of physical activity. These results can be used to revise the curriculum in schools, promote equal opportunities for physical activity and support family participation.</p>

<title><bold>Introduction</bold></title>
<p>The World Health Organization (WHO) [<xref ref-type="bibr" rid="ref.3.1.1">1</xref>] states that physical inactivity is the fourth leading tisk factor for mortality worldwide (6% of deaths) after hypertension (13%), tobacco use (9%), excess glucose (6%), ahead of obesity (5%). The WHO [<xref ref-type="bibr" rid="ref.3.1.1">1</xref>] recommends 150 min per week of moderate aerobic physical activity or 75 min per week of vigorous aerobic physical activity or a combination of both. In Spain, the National Health Survey in Spain in 2017 [<xref ref-type="bibr" rid="ref.3.1.2">2</xref>] describes how 36.04% of the interviewees perceive themselves to be sedentary in their free time. This figure varies according to nationality, with 35.02% of individuals born in Spain admitting to being sedentary compared to 43.18% of individuals whose country of origin was not Spanish (immigrants). This difference increased in individuals aged between 15 and 24 years old by more than 10 points, and by 12 points in individuals <target target-type="page" id="pges_60"/>aged between 25 and 64 years old. Immigrant men and women are more sedentary compared to Spanish men and women in the same age groups. However, minors of foreign nationality are more active in their free time than natives (up to six points difference among sexes).</p>
<p>Previous studies [<xref ref-type="bibr" rid="ref.3.1.3">3</xref>-<xref ref-type="bibr" rid="ref.3.1.7">7</xref>] conducted in the USA and European countries show that children with foreign parents were less physically active than children with native parents. Griffiths et al. [<xref ref-type="bibr" rid="ref.3.1.6">6</xref>] described how, in children over the age of seven with immigrant parents, 40% had a level of physical activity considered &#x201C;adequate&#x201D; compared to 50% of children with native British parents. Recent European studies show that young immigrants have more difficulty accessing sports clubs and are less physically active than natives [<xref ref-type="bibr" rid="ref.3.1.8">8</xref>-<xref ref-type="bibr" rid="ref.3.1.10">10</xref>]. However, the study by Reimers et al. shows that foreigners participate much more in the extracurricular activities offered at educational centers [<xref ref-type="bibr" rid="ref.3.1.8">8</xref>]. The difference in the manner in which native people and foreigners practice physical activity can change when immigrants have been in the country longer or if they are second-generation immigrants [<xref ref-type="bibr" rid="ref.3.1.11">11</xref>,<xref ref-type="bibr" rid="ref.3.1.12">12</xref>]. This difference decreases if the children are second-generation immigrants [<xref ref-type="bibr" rid="ref.3.1.4">4</xref>].</p>
<p>Physical activity in children and adolescents becomes important in relation to obesity. Obesity is a non-transmittable disease considered by the WHO as the fifth mortality factor in the world [<xref ref-type="bibr" rid="ref.3.1.1">1</xref>]. Obesity in children and adolescents is a very important factor in early metabolic syndrome and the development of cardiorespiratory diseases [<xref ref-type="bibr" rid="ref.3.1.13">13</xref>]. It is a major health risk, although it can be overcome through physical activity [<xref ref-type="bibr" rid="ref.3.1.14">14</xref>], In Spain, according to the National Health Survey [<xref ref-type="bibr" rid="ref.3.1.2">2</xref>], Spaniards show a higher percentage of overweight and/or obesity than the immigrant population. However, between 18 and 24 years of age, the immigrant population is more overweight and/or obese than the native population (32.95% versus 24.09% respectively). Foreign women, present greater overweight and obesity between 18 and 64 years of age, compared with Spanish women. In the case of children, there are higher rates of obesity among Spanish children than in immigrant children, in both sexes. These findings are in contrast with a report by Mar&#x00ED;n-Guerrero et al. [<xref ref-type="bibr" rid="ref.3.1.15">15</xref>] in the Community of Madrid who reported a high prevalence of obesity among the foreign population. A review published in 2014 [<xref ref-type="bibr" rid="ref.3.1.16">16</xref>] also demonstrated this prevalence of obesity among the immigrant population.</p>
<p>Other factors, such as environmental and/or socio-ecological factors influence the practice of physical activity or the prevalence of obesity [<xref ref-type="bibr" rid="ref.3.1.17">17</xref>-<xref ref-type="bibr" rid="ref.3.1.20">20</xref>]. Previous qualitative studies [<xref ref-type="bibr" rid="ref.3.1.7">7</xref>,<xref ref-type="bibr" rid="ref.3.1.11">11</xref>,<xref ref-type="bibr" rid="ref.3.1.21">21</xref>] reported that the factors that limit the practice of physical activity among immigrant children are both environmental barriers (insecurity, lack of sports or leisure resources, and lack of transportation), and socioeconomic barriers (lack of time or income), as well as cultural barriers (religion/beliefs, educational level, language, or gender inequality), which may prevent or limit the practice of physical activity among immigrant children, compared to native children. In addition, the parents&#x2019; sporting and eating behavior are also relevant factors in children&#x2019;s behavior [<xref ref-type="bibr" rid="ref.3.1.14">14</xref>,<xref ref-type="bibr" rid="ref.3.1.22">22</xref>,<xref ref-type="bibr" rid="ref.3.1.23">23</xref>], as they act as role models. Mart&#x00ED;nez-Andr&#x00E9;s et al. [<xref ref-type="bibr" rid="ref.3.1.24">24</xref>] describe how parents organize family life according to their own perspectives and priorities, putting educational activities first and leaving physical leisure activities for later.</p>
<p>In Spain, the immigrant population represents 10% of the total population in 2019 [<xref ref-type="bibr" rid="ref.3.1.25">25</xref>], and it is predicted that the immigrant population will represent up to 20% of the total population of Spain in 2033 [<xref ref-type="bibr" rid="ref.3.1.26">26</xref>]. This increase in population means that new families will be incorporated, with habits and customs, which could be subject to risk and/or protective factors such as physical activity or sedentary behavior. At this point, the authors believe that the parents&#x2019; perspective is fundamental in order to establish adherence to healthy habits such as physical activity.</p>
<p>The questions guiding this study are: How do immigrant parents perceive physical activity? What does it mean to them? Do they consider that exercise to be an educational asset or a healthy lifestyle habit that is passed on to their children? Answering these questions may help to understand the role of parents in the practice of physical activity among immigrant children and adolescents and in relation to the acquisition of healthy habits. The aim of this study was to describe the perspectives of immigrant parents on physical activity and how this applies to their children.</p>

<title><italic>Design</italic></title>
<p>A qualitative exploratory case study, using an interpretivist paradigm [<xref ref-type="bibr" rid="ref.3.1.27">27</xref>]. A case study is a research design that involves an examination of a contemporary phenomenon in a real-life setting [<xref ref-type="bibr" rid="ref.3.1.28">28</xref>]. It is used to explore and describe a single case bounded in time and place (i.e., the parents&#x2019; perspective regarding their children&#x2019;s physical activity). Moreover, a qualitative case study can be used to describe participants&#x2019; experiences regarding care, policy change, and understand why behaviors and complex interventions succeed or fail [<xref ref-type="bibr" rid="ref.3.1.28">28</xref>]. This research followed the international recommendations for conducting qualitative studies established by the Consolidated Criteria for Reporting Qualitative Research (COREQ) [<xref ref-type="bibr" rid="ref.3.1.29">29</xref>] and the Standards for Reporting Qualitative Research (SRQR) [<xref ref-type="bibr" rid="ref.3.1.30">30</xref>] (<ext-link ext-link-type="uri" xlink:href="http://www.equator-network.org/">http://www.equator-network.org/</ext-link>).</p>

<title><italic>Study Context</italic></title>
<p>Alcorc&#x00F3;n is a municipality of 33.73 km<sup>2</sup>, located 13 km Southwest from Madrid, in the Metropolitan Area of Madrid, within the province of Madrid (Community of Madrid, Spain). The greatest population growth took place in the 1970s, mainly due to the settlement of immigrants from other regions of Spain [<xref ref-type="bibr" rid="ref.3.1.31">31</xref>]. Currently, in the Community of Madrid, where the municipality of Alcorc&#x00F3;n is located, the percentage of physical inactivity among adolescents is 30%. In relation to the situation of the immigrant population in terms of physical activity, the Community of Madrid reports a percentage of inactivity of approximately 39% among immigrant adolescents [<xref ref-type="bibr" rid="ref.3.1.2">2</xref>]. Alcorc&#x00F3;n is one of the municipalities with the largest foreign population in the community of Madrid, and therefore there is a need for studies to deepen our knowledge of the physical activity dynamics among this group.</p>
<p>For this reason, the authors decided to visit institutions or centers where the population of South American immigrants gather for worship, or for cultural and civic activities, and where there were greater possibilities of recruiting participants for the study. The Caritas organization of the Parish Inmaculada Concepci&#x00F3;n de Nuestra Se&#x00F1;ora and the Parish Nuestra Se&#x00F1;ora de la Saleta, where large groups of South American immigrants met every Sunday and holiday, were particularly relevant.</p>
<p>The participants attended the Parish Inmaculada Concepci&#x00F3;n de Nuestra Se&#x00F1;ora (Alcorc&#x00F3;n, Madrid) and the Parish Nuestra Se&#x00F1;ora de la Saleta (Alcorc&#x00F3;n, Madrid). Both these parishes had programs for assisting and supporting the integration of immigrant families. These programs included the implementation of healthy habits in children and adolescents through physical activity.</p>

<title><italic>Participants</italic></title>
<p>The inclusion criteria were; (a) parents living in the Community of Madrid, (b) born in countries outside Spain and the European Union, (c) who at the time of the study had children over three years old in the Spanish education system, (d) who belonged to the Caritas organization of the Parish Inmaculada Concepci&#x00F3;n de Nuestra Se&#x00F1;ora or the Parish Nuestra Se&#x00F1;ora de la Saleta, and (e) who signed the informed consent. The exclusion criteria were: (a) parents under 18 years of age, (b) refusal to participate in the study, (c) native parents (born in Spain) and (d) not signing the informed consent.</p>

<title><italic>Sampling Strategy</italic></title>
<p>In qualitative research, sampling is the process of selecting or searching for situations, contexts and/or participants that provide rich data of the phenomenon of interest [<xref ref-type="bibr" rid="ref.3.1.32">32</xref>]. Non-probabilistic purposive sampling was performed [<xref ref-type="bibr" rid="ref.3.1.33">33</xref>], in which participants were selected based on their ability to provide relevant information to answer the study question. Sampling continued until the ongoing analysis revealed data redundancy [<xref ref-type="bibr" rid="ref.3.1.32">32</xref>]. Finally, 12 participants were included in the sample and none withdrew from the study.</p>

<title><italic>Data Collection</italic></title>
<p>Data were collected via unstructured interviews conducted in Spanish [<xref ref-type="bibr" rid="ref.3.1.33">33</xref>]. These interviews allow for inquiry and questioning in an open and flexible manner without imposing the researcher&#x2019;s perspective [<xref ref-type="bibr" rid="ref.3.1.34">34</xref>]. This enables participants to describe and narrate what is most relevant to them. The interview consisted of several open-ended questions: How is your experience with physical activity? Do you think it is relevant for your children? Based on these questions, the researcher wrote down the words, concepts and expressions that the participants used to cross-examine them. Repeating the cycle over and over again, deepening the participant&#x2019;s experience [<xref ref-type="bibr" rid="ref.3.1.33">33</xref>]. Overall, 20 interviews were conducted, and 20 researchers&#x2019; field notes were collected. Eight participants were interviewed on two separate occasions, as it was necessary to collect more information. The remaining participants received a single interview.</p>

<title><italic>Data Analysis</italic></title>
<p>A thematic analysis was applied for the description and interpretation of parents&#x2019; narratives [<xref ref-type="bibr" rid="ref.3.1.35">35</xref>]. The analysis was conducted on all interview transcripts [<xref ref-type="bibr" rid="ref.3.1.34">34</xref>]. In the coding process, the descriptive components that made up the participants&#x2019; experience were identified, these descriptive components formed meaning units, which were then grouped into common groups of meaning, to finally identify the themes that described the participants&#x2019; perspective [<xref ref-type="bibr" rid="ref.3.1.35">35</xref>].</p>

<p>The study was approved by the Ethics and Clinical Research Committee of the Rey Juan Carlos University (code: 3001201702417). In addition, the Data Protection Law (Law 15/1999) was complied with, guaranteeing confidentiality and good practice standards.

<title><italic>Quality Criteria</italic></title>
<p>In addition to following the COREQ [<xref ref-type="bibr" rid="ref.3.1.29">29</xref>] and SRQR [<xref ref-type="bibr" rid="ref.3.1.30">30</xref>] recommendations, the Guba and Lincoln criteria were applied to establish credibility, transferability, dependability, and confirmability [<xref ref-type="bibr" rid="ref.3.1.36">36</xref>]. The techniques to ensure credibility were; researcher triangulation, triangulation of data collection instruments, and participant validation. For transferability, the research protocol, and the context and participants of the study were described in detail. An external auditor/researcher was used to ensure confidence. This external auditor reviewed the research protocol, focusing on the development of materials and methods. External audits involve having a researcher who is not involved in the research process examine both the process and product of the research study. The purpose is to evaluate the accuracy and evaluate whether or not the findings, interpretations and conclusions are supported by the data. In the present study, four external audit trials were performed, prior to commencing the study (before February 2017), twice during the study (from February 2017 to June 2017; in March and May 2017), and once after completion of the study (after June 2017). Finally, for the purpose of confirmability, the researchers&#x2019; reflexivity process was applied, holding meetings to establish the research team&#x2019;s prior position on the topic under study [<xref ref-type="bibr" rid="ref.3.1.33">33</xref>].</p>

<title><italic>Physical Activity and Health</italic></title>
<p>Participants (n = 9) described how physical activity leads to better fitness, better health, improved quality of life and physical well-being: &#x201C;Being more active, more agile, and breathing better, feeling better in general&#x201D; (P5, female, income level IV).</p>
<p>In addition, they also referred to how physical activity improves mental health: &#x201C;You have to exercise to be well, to improve your self-esteem, in terms of mental health&#x201D; (P1, female, income level V); &#x201C;Changing your routine, obtaining relief, is a way of relieving everyday tension, even, calming the mind&#x201D; (P4, male, income level IV).</p>

<title><italic>Socialization</italic></title>
<p>For parents (n = 8), physical activity supports socialization and helps instill certain values in their children. The narratives highlight the relevance of this for parents: &#x201C;It is very important for them to practice physical activity, to socialize and get along in life&#x201D; (P2, male, income level V); &#x201C;They share with friends at school and learn to share with people outside school, in the parks&#x201D; (P4, male, income level IV); &#x201C;Doing something in a group is important. Belonging to a team is important&#x201D; (P5, female, income level IV).</p>
<p>The narratives (n = 5) highlight the belief that practicing physical activity as a child can help their children be healthier when they reach adulthood: &#x201C;You will always have better health conditions if you move, than if you are a sedentary person&#x201D; (P6, male, income level III).</p>

<title><italic>The Need for Movement</italic></title>
<p>For the interviewees (n = 5), movement was a recurrent theme when qualifying and defining physical activity. Physical activity consists of movement, agility, physical space, the natural environment and play. In contrast to being sedentary, or confining a child to the house, which was compared to being cooped up in a cage: &#x201C;Children live in cages, they are locked up&#x201D; (P9, female, income level III).</p>
<p>Seven participants also compared the way children play and practice physical activity in Spain in relation to their countries of origin. Thus, in Spain, both children and people, in general, spend more time indoors, and consequently, they are more sedentary. In addition, they voiced their concerns with regard school environments, feeling that movement should be granted equal or greater importance as intellectual activity: &#x201C;They need to get out of the chair and not just exercise the brain, which is also important&#x201D; (P12, female, income level V).</p>

<title><target target-type="page" id="pges_65"/><italic>Gender</italic></title>
<p>The narratives also revealed differences in sports practice by gender. All participants unanimously stated that there should not be any difference in physical activity practice between boys and girls. Thus, no activity should be reserved for only one sex. Every child should be free to choose and practice the activities he or she desires: &#x201C;I don&#x2019;t think that sport has anything to do with sexual personality. As long as they feel good&#x201D; (P10, male, income level V).</p>
<p>However, all parents&#x2019; acknowledged differences between boys and girls. Boys play more football and girls play more sports like volleyball or gymnastics: &#x201C;Football is played by boys. There are more and more girls, but it&#x2019;s a boy thing. In my country, girls practice a lot of volleyball and rhythmic gymnastics. It is very rare for boys to play such sports&#x201D; (P6, female, income level III).</p>

<title><italic>Barriers</italic></title>
<p>Barriers encountered by parents when encouraging and/or practicing physical activity with their children include: economic barriers, infrastructure barriers, time-related barriers, environmental barriers, or barriers due to fear and insecurity.</p>
<sec id="c3-s2-s3-s5-s1">
<label>3.5.1.</label>
<title>Economic Barriers</title>
<p>Eight participants reported that families must cover significant economic expenses when their children engage in any kind of organized or regulated physical activity: &#x201C;If you want your child to practice, you have to pay and that seems overwhelming to me&#x201D; (P1, female, income level V); &#x201C;If you don&#x2019;t have help, I can&#x2019;t afford it. It&#x2019;s an expense I can&#x2019;t afford.&#x201D; (P2, male, income level V).</p>
<p>A difference was highlighted between the country of origin and Spain. Family benefits are more extensive in Latin American countries, allowing families to participate in physical activities with their children: &#x201C;There are associations that provide free training. There are also sports centers belonging to the city council, and everything is free&#x201D; (P8, male, income level V).</p>
<p>The concept of &#x201C;sacrifice&#x201D; appeared in the participants&#x2019; narratives (n = 5). Families much make a great sacrifice in order to enable their children to practice some kind of activity: &#x201C;I know many friends who have to make great efforts to get their children to play soccer, they sacrifice a lot for them&#x201D; (P6, female, income level III).</p>
<p>Finally, having to register with a club, or a sports school, is considered another barrier for four participants. In addition to having to pay registration fees, specific material equipment is required: &#x201C;Here you must pay for everything, you have to put them in a defined, organized team. If you don&#x2019;t have the right boots, you can&#x2019;t play&#x201D; (P11, male, income level IV).</p>
</sec>
<sec id="c3-s2-s3-s5-s2">
<label>3.5.2.</label>
<title>Infrastructure Barriers</title>
<p>Our participants (n = 7) reported that the availability of sports and/or leisure infrastructures near the family home, and their distance influences the child&#x2019;s physical activity. The narratives show that the absence of facilities conditions and prevents children&#x2019;s engagement in physical activity: &#x201C;In the case of Parla, it is an abandoned village. There is no place to do sport. There is neither a field nor a sports center to take them to, there are no sports areas&#x201D; (P1, female, income level V).</p>
<p>Parents (n = 5) reported that the greater the distance from the facilities, the less likely their children are to practice physical or sporting activities. Substantial time is involved in travelling to and from these centers: &#x201C;There is a lake, it is a very big park, but mothers do not always have the availability to go there every day. It&#x2019;s far away and, without a car, it&#x2019;s impossible&#x201D; (P9, female, income level III).</p>
</sec>
<sec id="c3-s2-s3-s5-s3">
<label>3.5.3.</label>
<title>Time-Related Barriers</title>
<p>In order for their children to be physically active, parents (n = 7) must invest large amounts of their time. However, often, parents (n = 4) complained of a lack of time available, either because of an extended working day, and/or because their work hours are incompatible with the child&#x2019;s leisure time. Six parents described that their working hours are intense and this does not allow them to take <target target-type="page" id="pges_66"/>their children to organized physical activities or to the park: &#x201C;Work has a great influence, you cannot spend enough time with them (the children) either. If you don&#x2019;t have enough time, you can&#x2019;t do it either&#x201D; (P10, male, income level V).</p>
<p>This lack of time influences children&#x2019;s physical activity, as well as having an impact on parents&#x2019; practice (n = 5). Thus, parents assigned priority to their children&#x2019;s practice of physical activity and leisure above over their own: &#x201C;We have a lot of work. And I prefer to spend more time with my children instead of going to do sport&#x201D; (P4, male, income level IV); &#x201C;But I can&#x2019;t do sport with the children anymore. For me it is a big obstacle to do physical activities&#x201D; (P12, female, income level V).</p>
<p>Other key points raised were: the lack of time, organizing the child&#x2019;s schedule and the pace of the day. The participants (n = 3) described how the proposed timetable for practicing sports activities was unsuitable, both for their children and for the ability to balance work/family life: &#x201C;The extracurricular activities that we can take them to, which are often more compatible with my work, are more expensive&#x201D; (P5, female, income level IV); &#x201C;My son had a scholarship because he came first at a sports meet at the town hall, but the timetable was from 6.30 p.m. to 7.30 p.m., and I can&#x2019;t take them at that time. What did I end up doing? We took him out, we couldn&#x2019;t go&#x201D; (P8, female, income level V).</p>
</sec>
<sec id="c3-s2-s3-s5-s4">
<label>3.5.4.</label>
<title>Environmental Barrier</title>
<p>The parent&#x2019;s narratives (n = 5) describe how the lack of nature or a natural environment near the homes is a constraint for engaging in physical activity: &#x201C;In my country, there is more freedom to play sports outdoors than here, the children still go down to the street to play football&#x201D; (P2, male, income level V); &#x201C;We are much more limited here by the surrounding environment&#x201D; (P7, male, income level IV).</p>
</sec>
<sec id="c3-s2-s3-s5-s5">
<label>3.5.5.</label>
<title>Barriers due to Fear and Insecurity</title>
<p>This refers to the insecurity and fear that parents (n = 7) feel when they take their children to physical activities in an unsafe environment. Some (n = 3) felt &#x201C;terrified&#x201D; due to the feelings of insecurity when going to some of the parks. In addition, if there are areas that are not recommended for children because of insecurity, they feel that it is unsafe to leave children alone in the street to play ball: &#x201C;The courts are full of people who hurt the children, and as a mother I feel afraid to let them go&#x201D; (P2, male, income level V); &#x201C;Here you feel terrified of taking them. There&#x2019;s a big park, but since everyone goes, it scares you. And in the street you can&#x2019;t leave them alone either&#x201D; (P11, male, income level IV).</p>
<p>In contrast, participant 3 expressed opposite feelings, in Spain he did not fear taking his children to the park or letting them play in the street, compared to his native country, Colombia: &#x201C;In Colombia, there is a lot of crime. You can&#x2019;t do anything outdoors in my country. In Spain, you go for a run and you aren&#x2019;t afraid of being robbed. In my country, the fear of going out is huge&#x201D; (P3, female, income level V).</p>

<sec id="c3-s2-s3-s6">
<label><italic>3.6.</italic></label>
<title><italic>Educational Burden</italic></title>
<p>It refers to the burden of homework and school-related activities that children must engage in after the school day. Parents (n = 5) narrate how their children have to study a lot, both during school hours and during &#x201C;so-called&#x201D; leisure time. The complaint shared by all parents is that the educational burden is greater and more important than enjoying leisure time. The time dedicated to homework is a deterrent for the practice of extra-curricular activities: &#x201C;They have a great deal of theory. They come super tired (from school), they have to study and they don&#x2019;t want to do anything else&#x201D; (P11, male, income level IV).</p>
<p>Most of the interviewees (n = 10) felt that the school curriculum does not assign enough importance to physical activities, as the theoretical burden is very demanding: &#x201C;The excess of homework compels them not to do sports or have fun&#x201D; (P9, female, income level III); &#x201C;The education <target target-type="page" id="pges_67"/>system has bad schedules that do not let the child be a child. If school schedules were better organized, they could have more time to play and be children&#x201D; (P6, female, income level III).</p>
</sec>
<sec id="c3-s2-s3-s7">
<label><italic>3.7.</italic></label>
<title><italic>Community Living</italic></title>
<p>Sometimes, problems arise in the neighborhood communities, because of community norms that do not allow children to play certain activities in the courtyards. Specifically, it is often forbidden to play ball: &#x201C;In the communities you can&#x2019;t play, the rules of the communities don&#x2019;t allow them to play ball, they are children, that&#x2019;s what they should do&#x201D; (P9, female, income level III).</p>
<p>Parents (n = 4) described how in their countries of origin there is more freedom to play or practice physical activity in the street compared to Spain. They report that, regarding the community relations between neighbors, it is accepted that children should play and do physical activity (sport): &#x201C;In my country, we don&#x2019;t live in buildings, we can all play in the street, people go out and everyone starts to play, they go on their bikes or dance. We don&#x2019;t get angry about these things&#x201D; (P10, male, income level V).</p>

<label><italic>3.8.</italic></label>
<title><italic>The Reason for Immigrating</italic></title>
<p>Most parents (n = 10) acknowledged that their reason for immigrating was financial. They need to earn money to be able to send it back to their native country, or save enough to return to their country in the future. Thus, physical activity is not a priority for them. This influences their children&#x2019;s physical activity and the time they spend with them, since the goal is to work more to earn more: &#x201C;An immigrant wants to return to his or her country. Earn money and return. We come here to work, to earn money, and we don&#x2019;t have time to be active, sometimes we don&#x2019;t even have time for our own children&#x201D; (P7, male, income level IV).</p>

<title><bold>Discussion</bold></title>
<p>The socio-demographic data shown in <xref ref-type="table" rid="c3-s2-tab1">Table 1</xref> contextualize the results obtained from the participants&#x2019; narratives. Accordingly, in order to understand the results, it is necessary to contextualize which participants provided narrations regarding their experience [<xref ref-type="bibr" rid="ref.3.1.27">27</xref>,<xref ref-type="bibr" rid="ref.3.1.33">33</xref>]. In this study, the participants were mostly middle-aged women, most of whom did not engage in physical activity in their free time and earned less than 1550 to 2200 euros per month.</p>
<p>This paper aimed to describe the meaning of children&#x2019;s physical activity from the perspective of immigrant parents. Previous studies [<xref ref-type="bibr" rid="ref.3.1.3">3</xref>-<xref ref-type="bibr" rid="ref.3.1.5">5</xref>,<xref ref-type="bibr" rid="ref.3.1.11">11</xref>,<xref ref-type="bibr" rid="ref.3.1.24">24</xref>] show how young people and children whose parents are immigrants were less physically active than their native counterparts.</p>
<p>Our results coincide with previous studies [<xref ref-type="bibr" rid="ref.3.1.38">38</xref>] showing that physical activity is perceived by parents as a health benefit and should be practiced because of its physical and psychological effects. In addition, our participants perceived that physical activity also has a socializing effect. Similar results have been published by Carratal&#x00E1; and Carratal&#x00E1; [<xref ref-type="bibr" rid="ref.3.1.39">39</xref>] and Delgado [<xref ref-type="bibr" rid="ref.3.1.40">40</xref>], showing how physical activity is a socializing agent, in terms of integrating rules, as well as developing responsibility and a sense of companionship.</p>
<p>Physical activity is perceived as being very closely related to movement [<xref ref-type="bibr" rid="ref.3.1.41">41</xref>-<xref ref-type="bibr" rid="ref.3.1.44">44</xref>]. Our participants reported that in certain physical activities and sports there is a gender distribution. In Spain, the survey of sports habits published by the Ministry of Education, Culture and Sport [<xref ref-type="bibr" rid="ref.3.1.45">45</xref>], shows that boys mostly practice sports such as soccer, cycling and swimming, and girls mostly practice gymnastics, hiking and swimming.</p>
<p>In most interviews, participants compared their country of origin with Spain. They used the words &#x201C;there and here&#x201D; a lot. There is an important influence between what they knew before and what they know now, with important economic and cultural influences.</p>
<p>Parents find it difficult to be physically active. Previous studies describe how the lower the socioeconomic level, the less possibility of physical practice there is [<xref ref-type="bibr" rid="ref.3.1.11">11</xref>,<xref ref-type="bibr" rid="ref.3.1.46">46</xref>]. Participants in our study acknowledged that the availability of financial resources significantly influences the decisions made regarding their child&#x2019;s physical activity. Our results highlight that participants prioritize the financial <target target-type="page" id="pges_68"/>well-being of the family over any health or leisure activity. Bhatnagar et al. [<xref ref-type="bibr" rid="ref.3.1.4">4</xref>] describe how this situation tends to change in the following generations, because having access to greater financial resources (a more stable livelihood) allows the family&#x2019;s priorities to be reorganized. Our results are in line with the qualitative study by Condon and McClean [<xref ref-type="bibr" rid="ref.3.1.12">12</xref>], describing that immigrants who are undergoing financial hardships must focus on improving the family economy, being unable to participate or promote the physical activity of their children. Foreigners do not have a socioeconomic level that allows them to justify an added economic expense, since the socioeconomic level of foreigners in Spain is low or medium [<xref ref-type="bibr" rid="ref.3.1.47">47</xref>]. According to the 2007 National Immigrant Survey, 40% of foreign nationals work in unskilled labor whereas 22% work in skilled labor [<xref ref-type="bibr" rid="ref.3.1.47">47</xref>]. These two categories have the lowest overall purchasing power [<xref ref-type="bibr" rid="ref.3.1.26">26</xref>].</p>
<p>There is also a barrier related to infrastructure. The neighborhoods (Southern area of Madrid, Spain), where the interviews took place, are not adapted in terms of the number of parks, sports or leisure facilities. The physical environment, with large parks or natural spaces, is a key factor for good physical practice. If the physical (urban) environment often appears as a barrier to the practice of sports, physical and leisure activities, this is exacerbated in the case of immigrant parents, who are used to having a more open and natural physical environment in their countries of origin.</p>
<p>Lack of time is another limiting factor. The parents in this study described having long and overwhelming working hours that prevent them from doing any physical activity. Reimers et al. [<xref ref-type="bibr" rid="ref.3.1.8">8</xref>] reported that many parents cannot enroll their children in sports activities, let alone participate in them together. In addition, Reimers et al. [<xref ref-type="bibr" rid="ref.3.1.8">8</xref>] identified reduced physical activity related to the difficulty in accessing sports clubs and centers.</p>
<p>The proposed schedules for organized sports activities were considered by some of our participants as an added difficulty, as they described them as incompatible with their work schedules and family life rhythms. Previous studies [<xref ref-type="bibr" rid="ref.3.1.24">24</xref>,<xref ref-type="bibr" rid="ref.3.1.48">48</xref>,<xref ref-type="bibr" rid="ref.3.1.49">49</xref>] state that workloads and family burdens may prevent children and parents from practicing physical activity. In our study, five of the participants had three or more children. A large family could explain the difficulties in reconciling and organizing the family&#x2019;s daily routine when balancing the different activities, which could have an impact on enrolling their children in extracurricular or leisure activities.</p>
<p>Also, insecurity or fear of going out can influence the decision to take children to leisure areas. Owen et al. [<xref ref-type="bibr" rid="ref.3.1.50">50</xref>] and Motl et al. [<xref ref-type="bibr" rid="ref.3.1.51">51</xref>] describe insecurity as a barrier to sport. All these barriers coincide with previous studies [<xref ref-type="bibr" rid="ref.3.1.24">24</xref>,<xref ref-type="bibr" rid="ref.3.1.50">50</xref>-<xref ref-type="bibr" rid="ref.3.1.53">53</xref>] in research carried out in Spain, the United Kingdom and the USA.</p>
<p>The economic expense of certain physical activities (tuition, travel, etc.) could explain a decline in the practice of exercise among children of immigrant parents. In addition, the parent&#x2019;s financial situation, together with a precarious job situation and long working hours, and the need to earn money and save it, condition the ability to spend money on their child&#x2019;s physical activity practice. Condon and McClean [<xref ref-type="bibr" rid="ref.3.1.12">12</xref>] describe the difficulty of maintaining the physical health of family members, as opposed to the priority of financial health. Participants in the former study were aware of their children&#x2019;s lack of physical activity, and acknowledged that they did not get enough exercise because of financial hardship, time constraints or feelings of insecurity in some neighborhoods [<xref ref-type="bibr" rid="ref.3.1.24">24</xref>]. Our results show how participants prioritize work and economic status over their children&#x2019;s physical activity. This could be explained by the fact that our participants have been in Spain for less than five years. This means that the parents still have a precarious and/or vulnerable socioeconomic situation and need to find financial stability before they can incorporate the family and their children into other activities.</p>
<p>Finally, the importance of knowing the perspectives of parents regarding physical activity is underlined, as parents can play a crucial role in determining their children&#x2019;s sedentary behaviors. Two recent studies in Asia [<xref ref-type="bibr" rid="ref.3.1.54">54</xref>,<xref ref-type="bibr" rid="ref.3.1.55">55</xref>] showed the mutually interdependent relationship between parents&#x2019; and children&#x2019;s physical activity and screen-viewing behaviors, highlighting the impact on children&#x2019;s health. The results show the potential mechanistic link between parents&#x2019; perspectives on physical activities and children&#x2019;s health outcomes, showing that parents&#x2019; screen-viewing behaviors and rules may be associated with their children&#x2019;s insufficient physical activity levels and overweight problems. In the opinion of the authors, future lines of intervention for pediatric overweight should <target target-type="page" id="pges_69"/>consider the inclusion of educational and behavioral programs designed for parents, instead of focusing only on children [<xref ref-type="bibr" rid="ref.3.1.54">54</xref>].</p>
<p>This study has several limitations. First, we were unable to carry out a homogeneous grouping of immigrant parents by geographically defined areas. Secondly, we did not identify whether the children of the parents were born in Spain or were transferred from their country of origin. The authors believe that this limitation is controlled, since the aim of the study was to describe the perspective of the parents and not that of the children. Additionally, the present study included 12 participants, and 20 interviews have been performed. Previous qualitative studies [<xref ref-type="bibr" rid="ref.3.1.27">27</xref>,<xref ref-type="bibr" rid="ref.3.1.33">33</xref>,<xref ref-type="bibr" rid="ref.3.1.56">56</xref>] have described how the total number of participants included does not depend on a previous calculation of the sample size, rather it is based on the saturation or redundancy of the information obtained in the interviews. Turner-Bowker et al. [<xref ref-type="bibr" rid="ref.3.1.57">57</xref>] reported that 92&#x2013;97% of the saturation can be analyzed after interview numbers 15 and 20. In addition, our results cannot be extrapolated to all immigrant parents who have children, due to the design used. Nonetheless, these results may help professionals understand parents&#x2019; experiences, and their difficulties in promoting physical activity and resources for their children. Finally, this study did not perform a cultural comparison between groups of native parents and immigrant parents.</p>

<title><bold>Conclusions</bold></title>
<p>This study describes the factors related to the physical activity of South American immigrant children from the parents&#x2019; perspective. Our results revealed that the immigrant parents who were recruited in this study perceived that their children&#x2019;s physical activity was relevant and important to their future lives. However, certain barriers exist which limit and prevent the ability for foreign children to exercise, such as income, time availability or extended work shifts.</p>
<p>These results can be used to guide the programming and organization of physical activities in the school and community environment. It is also essential to provide policies to reconcile family and work, so that the lack of time is not a hindrance to the practice of physical activity. It is essential to create policies for financial aid targeted at the most disadvantaged families. In addition, it is necessary to invest in the creation of safe spaces and sports and leisure infrastructures to promote physical activity within the community.</p>
<p>A future line of research would be to carry out a cultural comparison between groups of immigrant and native parents, using a qualitative ethnographic design.</p>

<p>Physical activity (PA) contributes to the development of children and adolescents and to their mental and physical health. The practice of PA in the school context can contribute towards generating a more inclusive educational community for immigrant children and adolescents. The aim of this study was to describe the perspectives of Spanish physical education (PE) teachers on the practice of PA among immigrant children and adolescents. This research was a qualitative exploratory study. A purposeful sampling strategy was used. Data were collected through semi-structured interviews and field notes. Twenty teachers were recruited. An inductive thematic analysis and content analysis were applied. The following topics were identified: (a) Professional expectations; (b) Economic resources; (c) Integration; (d) Family; (e) Religious beliefs and practices; and (f) Gender difference. A predominance of positive emotions was identified in the narratives, and the most repeated words in word clouds were &#x2018;Caribbean&#x2019;, &#x2018;Latin&#x2019;, and &#x2018;population&#x2019;. These findings help to identify PA barriers for immigrant children and adolescents and may contribute to the creation of PA-based interventions in social and educational contexts.</p>

<title><bold>Introduction</bold></title>
<p>Physical activity (PA) is defined as &#x201C; &#x2026; any bodily movement produced by skeletal muscle that requires energy expenditure&#x201D; [<xref ref-type="bibr" rid="ref.3.2.1">1</xref>,<xref ref-type="bibr" rid="ref.3.2.2">2</xref>]. Physical activity is beneficial at all ages and is recommended as an active practice in early childhood, necessary for the healthy development of both children and adolescents. [<xref ref-type="bibr" rid="ref.3.2.3">3</xref>-<xref ref-type="bibr" rid="ref.3.2.5">5</xref>]. In addition, it prevents diseases such as heart disease, hypertension, or obesity in adulthood [<xref ref-type="bibr" rid="ref.3.2.3">3</xref>-<xref ref-type="bibr" rid="ref.3.2.5">5</xref>]. Furthermore, positive effects on mental health have also been demonstrated, such as a decreased presence of anxious-depressive symptoms in children and adolescents [<xref ref-type="bibr" rid="ref.3.2.6">6</xref>,<xref ref-type="bibr" rid="ref.3.2.7">7</xref>]. Physical inactivity and sedentary lifestyles have been identified as health-related behaviors that negatively impact <target target-type="page" id="pges_75"/>quality of life during childhood and youth [<xref ref-type="bibr" rid="ref.3.2.2">2</xref>-<xref ref-type="bibr" rid="ref.3.2.4">4</xref>], noting that worldwide, 80% of adolescents are not sufficiently physically active [<xref ref-type="bibr" rid="ref.3.2.8">8</xref>]. Thus, the current recommendation for ages 5 to 17 is an average of 60 min per day of moderate to vigorous PA, mainly aerobic, at least 3 days per week [<xref ref-type="bibr" rid="ref.3.2.1">1</xref>,<xref ref-type="bibr" rid="ref.3.2.8">8</xref>].</p>
<p>The General Assembly of the United Nations adopted the 2030 Agenda for Sustainable Development Goals, highlighting how PE and opportunities for PA in schools contribute to promoting health and well-being and ensuring quality education in educational communities with different social realities [<xref ref-type="bibr" rid="ref.3.2.2">2</xref>,<xref ref-type="bibr" rid="ref.3.2.9">9</xref>]. In Europe, the increased immigration of recent decades has led to a large increase in cultural diversity among school-age students in educational contexts [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>]. Consequently, educational communities formed by teachers, parents and students are a key element for integration and social cohesion, where the role of PE classes and PE teachers in the generation of inclusive communities for immigrants is highlighted [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>]. The practice of PA in the school environment can contribute to improving interpersonal relationships and respect among the different perspectives and cultures that are part of the educational community [<xref ref-type="bibr" rid="ref.3.2.11">11</xref>,<xref ref-type="bibr" rid="ref.3.2.12">12</xref>], thus fostering feelings of inclusion and belonging to the community [<xref ref-type="bibr" rid="ref.3.2.13">13</xref>]. The feelings of inclusion and belonging favors the emotional well-being of immigrant children and adolescents and promotes and facilitates their adaptation to societies they have emigrated to [<xref ref-type="bibr" rid="ref.3.2.13">13</xref>].</p>
<p>In Spain, the practice of PA in the school environment has been studied from the perspective of children [<xref ref-type="bibr" rid="ref.3.2.14">14</xref>], parents [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>] and teachers [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>,<xref ref-type="bibr" rid="ref.3.2.15">15</xref>,<xref ref-type="bibr" rid="ref.3.2.18">18</xref>,<xref ref-type="bibr" rid="ref.3.2.19">19</xref>], both in the general population [<xref ref-type="bibr" rid="ref.3.2.14">14</xref>,<xref ref-type="bibr" rid="ref.3.2.17">17</xref>] as well as specifically referring to the immigrant population [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>,<xref ref-type="bibr" rid="ref.3.2.15">15</xref>,<xref ref-type="bibr" rid="ref.3.2.16">16</xref>,<xref ref-type="bibr" rid="ref.3.2.18">18</xref>,<xref ref-type="bibr" rid="ref.3.2.19">19</xref>]. In the study by Martinez-Andr&#x00E9;s et al. [<xref ref-type="bibr" rid="ref.3.2.14">14</xref>] on the perception of the barriers encountered for the practice of PA in children between 8 and 11 years of age, the opportunities for the practice of PA are determined by the schedules established by their parents, in which the difficulty of reconciling work and family life and the prioritization of other types of academic activities over the practice of PA, together with the perceived danger of the community environment, favor more sedentary habits among the children. These results are consistent with studies carried out from the parents&#x2019; perspective [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>], in addition to identifying a greater difficulty for their children to participate in certain physical activities due to economic barriers [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>&#x2013;<xref ref-type="bibr" rid="ref.3.2.17">17</xref>], a greater difficulty of reconciling single-parent families, restriction of PA among children in informal contexts as a form of punishment, a lack of communication between the school and the family, the influence of the mass media [<xref ref-type="bibr" rid="ref.3.2.17">17</xref>], inadequacy of infrastructure and lack of natural environments for practice [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>], excessive homework [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>,<xref ref-type="bibr" rid="ref.3.2.16">16</xref>] and gender stereotypes and gender-related choices [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>,<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>,<xref ref-type="bibr" rid="ref.3.2.20">20</xref>]. Moreover, Tamura et al. [<xref ref-type="bibr" rid="ref.3.2.21">21</xref>] identified that social environments of violence and insecurity in the neighborhoods where children and adolescents live are associated with a decrease in the practice of PA, representing the main structural barrier. These same authors recommend improving the spaces in which PA is carried out, such as parks and other open-air venues. Previous studies [<xref ref-type="bibr" rid="ref.3.2.22">22</xref>,<xref ref-type="bibr" rid="ref.3.2.23">23</xref>] point to the presence of crime in the neighborhood, the precariousness of the facilities where PA is performed [<xref ref-type="bibr" rid="ref.3.2.22">22</xref>,<xref ref-type="bibr" rid="ref.3.2.23">23</xref>], and high-traffic levels [<xref ref-type="bibr" rid="ref.3.2.23">23</xref>] as barriers to performing PA in children and adolescents in immigrant settings. Recently, Hu et al. [<xref ref-type="bibr" rid="ref.3.2.24">24</xref>], in their systematic review on factors influencing the performance of PA in children and adolescents, pointed to unsafe neighborhoods and inaccessibility of PA venues as barriers.</p>
<p>From the teachers&#x2019; point of view, different perspectives have been identified, both among PE teachers and among teachers of subjects that take place in the regular classroom (subjects such as mathematics, science, etc.) [<xref ref-type="bibr" rid="ref.3.2.18">18</xref>]. For example, the imbalance between previous schooling and the level of the course in which they are enrolled, and the lack of knowledge of the language, are identified as elements that distort children&#x2019;s learning, according to teachers of classroom-taught subjects, while this issue is not perceived as a problem in the case of physical education (PE) classes [<xref ref-type="bibr" rid="ref.3.2.18">18</xref>]. Physical education teachers have been found to have an important role in promoting interculturality in Spanish schools [<xref ref-type="bibr" rid="ref.3.2.19">19</xref>]; therefore, the research on their perspective regarding PA practice in this population should be further expanded.</p>
<p><target target-type="page" id="pges_76"/>This study was based on the following research questions: How do PE teachers perceive PA in immigrant children and adolescents? What does it mean to them? Answering these questions may help to explain the role of PE teachers and their positioning regarding the promotion of PA practice among immigrant children and adolescents.</p>
<p>The aims were: (a) to describe the perspectives of PE teachers on PA and (b) barriers perceived and (c) to analyze the word frequency from interviews, to assess emotions and (d) to describe the polarity of their perspectives regarding PA.</p>

<p>The community of Madrid recorded a foreign population of 15% (1,026,333 inhabitants) in 2020 [<xref ref-type="bibr" rid="ref.3.2.29">29</xref>]. Of these, 52.5% were women, 14.15% were under 16 years of age, and 3.48% were between 16 and 19 years of age. The most frequent nationalities among the total foreign population in Madrid were Romania (18.21%), Morocco (8.18%), China (6.41%), Colombia (6.2%), Venezuela (5.91%) and Peru (4.24%). Currently, in Spain, the total number of foreign students is 862,520 (in the community of Madrid 151,603) [<xref ref-type="bibr" rid="ref.3.2.30">30</xref>].

<p>In qualitative studies, sampling is aimed at selecting those participants who have the relevant information about the phenomenon under study (PA practice) [<xref ref-type="bibr" rid="ref.3.2.32">32</xref>]. In the present study a non-probabilistic and purposeful sampling strategy were used based on their relevance to the research question rather than representativeness [<xref ref-type="bibr" rid="ref.3.2.32">32</xref>]. The inclusion criteria were: (a) PE teachers working in the community of Madrid, (b) who were actively working at an educational center during the study period, and (c) who had over four years&#x2019; teaching experience. The exclusion criteria were: (a) teachers who did not teach PE, and (b) not signing the informed consent.</p>

<title><italic>2.4. Data Collection</italic></title>
<p>Semi-structured interviews were used, which followed a question guide oriented to specific areas of interest [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>]. The question guide was constructed based on the literature review [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>,<xref ref-type="bibr" rid="ref.3.2.16">16</xref>] and the experience of the researchers [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>]. After obtaining personal and professional data from the participants, the interview began with an opening question: &#x201C;Please, can you share with me your personal perspective regarding teaching PA to immigrant children and adolescents?&#x201D; After this, open-ended follow-up questions were used to obtain detailed descriptions: 1. &#x201C;Could culture or ethnicity influence the acquisition of habits, such as PA?&#x201D;; 2. &#x201C;What role do parents play in immigrant children and adolescents&#x2019; adherence to PA?&#x201D;; 3. &#x201C;While teaching PA, have you experienced any critical event or relevant moment?&#x201D;; 4. &#x201C;What do you think are the keys to promoting PA in immigrant children and adolescents?&#x201D;; 5. &#x201C;What factors or elements can be considered facilitators or barriers in the acquisition of PA among immigrant children and adolescents?&#x201D; During the interview, the prompt &#x201C;Please tell me more about that&#x201D; was used to encourage participants to explore specific aspects in greater depth.</p>
<p>The interviews were tape-recorded and transcribed verbatim. Overall, 1026 min of data collection were recorded, with a mean of 51.3 min (SD 9.72). All interviews were held at the schools. We used researcher field notes as a secondary source of information to provide more in-depth information [<xref ref-type="bibr" rid="ref.3.2.21">21</xref>]. All interviews were conducted in Spanish.</p>

<title><italic>2.5. Data Analysis</italic></title>
<p>The interviews were analyzed by means of an inductive thematic analysis [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>,<xref ref-type="bibr" rid="ref.3.2.32">32</xref>] for the identification of the relevant themes obtained from the interviews, and a content analysis [<xref ref-type="bibr" rid="ref.3.2.33">33</xref>] of the participants&#x2019; words and narratives. From the content analysis we obtained: (a) a cloud of the most used words, and (b) identification of the feelings of the participants and the polarity of their narratives. The use of content analysis in interviews and written texts through statistical techniques is used in discourse analysis and qualitative studies as a method of deepening and triangulating the analysis [<xref ref-type="bibr" rid="ref.3.2.33">33</xref>].</p>
<p>Full transcripts were made of each in-depth interview and of the researchers&#x2019; field notes [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>,<xref ref-type="bibr" rid="ref.3.2.32">32</xref>]. Thematic analysis [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>] consisted of identifying text fragments with relevant information to answer the research question. From these narratives, the most descriptive contents (meaning units/codes) were identified. Subsequently, these units were grouped by their common meaning (common meaning groups) and/or similar content [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>,<xref ref-type="bibr" rid="ref.3.2.32">32</xref>]. During coding, 1049 codes were identified. Thematic analysis was applied separately to interviews and field notes by D.P.-C., J.N.C.-Z. and R.M. Joint team meetings were held to combine the results of the analysis and discuss data collection and analysis procedures. In these team meetings the final themes were displayed, combined, integrated and identified. In case of divergence of opinions, the identification of the theme was based on consensus among the members of the research team. Finally, six themes were identified. See Supplementary file, Figure SI Example of codification process.</p>
<p>For the statistical analysis of the qualitative content [<xref ref-type="bibr" rid="ref.3.2.33">33</xref>], the software R version 3.5.1 (R Foundation for Statistical Computing, Institute for Statistics and Mathematics, Welthandelsplatz 1, 1020 Vienna, Austria) was used. The text of the interviews was lemmatised for analysis. A word frequency analysis was carried out using the tf-idf algorithm (term frequency-inverse document frequency), and a wordcloud representing the most frequent use of words within the participants&#x2019; interviews was obtained. Emotion analysis was performed using Bing [<xref ref-type="bibr" rid="ref.3.2.34">34</xref>], Afinn [<xref ref-type="bibr" rid="ref.3.2.35">35</xref>] and National Research Council Canada (NRC) dictionaries [<xref ref-type="bibr" rid="ref.3.2.36">36</xref>&#x2013;<xref ref-type="bibr" rid="ref.3.2.38">38</xref>]. Text polarity was analysed, using the SODictionaries V1.11Spa dictionary as amplifiers and decrementators, the Bing dictionary [<xref ref-type="bibr" rid="ref.3.2.36">36</xref>&#x2013;<xref ref-type="bibr" rid="ref.3.2.38">38</xref>], and as deniers, those proposed by Vilares et al. [<xref ref-type="bibr" rid="ref.3.2.39">39</xref>]. For the analysis of polarity (acceptance-rejection) 4 stages were used. In the first stage, a file was created with the text of the interviews, broken down by <target target-type="page" id="pges_78"/>sentences for textual analysis. In the second stage, polarity was calculated using the Bing Sentiment Dictionary, amplifiers and de-amplifiers of SODictionar-iesV1.11Spa [<xref ref-type="bibr" rid="ref.3.2.36">36</xref>&#x2013;<xref ref-type="bibr" rid="ref.3.2.38">38</xref>] and the deniers proposed by Vilares et al. [<xref ref-type="bibr" rid="ref.3.2.39">39</xref>] (Figure S1). In the third stage, the scatter diagram of the sentences in the text in relation to neutrality was calculated to identify positive or negative tendencies. Finally, the evolution of emotional valence (positive-negative) was shown throughout the interviews. Fourier transformation was applied to confirm the polarity trend.</p>

<title><italic>Results of the Thematic Analysis</italic></title>
<p>The themes depict the teachers&#x2019; perspective, obtained after analysis of the researchers&#x2019; interviews and notes. Six barriers to PA practice were identified: Professional expectations, Economic resources, Integration, Family, Religious beliefs and practices, and Gender difference.</p>
<sec id="c3-s3-s3-s1-s1">
<label>3.1.1.</label>
<title>Future Professional Expectations</title>
<p>The participants reported that the parents of immigrant children and youth prioritize other subjects for their children over PE to avoid school failure, especially in the Asian community. Other extracurricular activities, such as English, have more weight than the practice of PA.</p>
<p>The participants spoke of how families with higher levels of education assign higher value to the practice of PA. In addition, from the teachers&#x2019; perspective, many families believe that the practice of PA is not necessarily conducive to getting a good job or being successful in society. Moreover, some families reportedly fail to consider the health benefits of PA. In turn, the teachers perceived that certain young people consider PA as a form of leisure, rather than a way of acquiring healthy habits for their lives. In other cases, teachers perceived that some young people view PA as a strategy to avoid family and social conflicts. Thus, PA is seen as a tool that helps young people to overcome problems arising within the family.</p>
</sec>
<sec id="c3-s3-s3-s1-s2">
<label>3.1.2.</label>
<title>Financial Resources</title>
<p>The study participants described that most immigrant families have low or limited financial resources. Furthermore, the teachers pointed out that having low financial resources influences the parent&#x2019;s ability to purchase clothing, footwear, and sports equipment. Sometimes, the practice of PA implies a substantial economic expense, comprising school or club enrollment fees and the payment of the monthly fee. Teachers reported that this is an expense that many families cannot afford. In addition, in the case of large families, the financial cost of sports equipment is multiplied and becomes a substantial burden for families.</p>
<disp-quote>
<p><target target-type="page" id="pges_79"/><italic>"Even if the activities are cheap, for an immigrant population that is short of money, spending &#x20AC;10 a month is a lot. If, in addition, there are 5 children, it is &#x20AC;50 a month and that is a lot of money. So, they aren&#x2019;t going to do it."</italic> (Teacher#0005#).</p>
</disp-quote>
<p>Another example of this situation is the performance of optional educational-sports activities at the high school, such as skiing, which immigrant students rarely have access to due to a lack of economic resources. The participants described that, as an alternative, many immigrant students practiced unregulated PA such as playing in the Street. Teachers reported that after-school PA programs at the Institutes for the Promotion of Physical Activity and Sport (Institutos Promotores de la Actividad F&#x00ED;sica y Deporte -IPAFD) promoted with public funds by the community of Madrid are mainly used by immigrant students. These programs cost &#x20AC;14 per year for 2 h of PA per week. This is an expense that families can afford.</p>
</sec>
<sec id="c3-s3-s3-s1-s3">
<label>3.1.3.</label>
<title>Integration</title>
<p>Participants perceived how some communities tend to be quite &#x201C;close-knitted&#x201D; and this can lead to difficulties for the integration of children and youth and their ability to practice PA. Indeed, the more integrated the children/youth are within the group and in class, the more they are involved in PA. Moreover, participants narrated how immigrant students tend to form groups among members of the same community, thus an invisible barrier is formed between Spanish students and students from other communities. Some participants used the term &#x201C;invisible barrier&#x201D; and this separation was especially identified in young people belonging to the Asian and Maghrebi communities. Some participants mentioned the presence of a kind of &#x201C;ghetto&#x201D; phenomenon in PA.</p>
<p>Furthermore, the participants stressed that students who have been in Spain longer, those who are second generation citizens, or who arrived during their childhood display less rejection towards PA. In particular, children and young people from the South American community were highlighted as being able to integrate more easily, because they share a common culture with the Spanish children. In addition, the participants reported how extracurricular activities were identified as a way to promote social integration. Thus, many students enroll in the programs of the IPAFD to integrate better into the class and make friends.</p>
</sec>
<sec id="c3-s3-s3-s1-s4">
<label>3.1.4.</label>
<title>The Family</title>
<p>All participants agreed that the influence of families is key to PA. Thus, the families represent a role model for young people. If the father or mother does not have the habit or possibility of practicing PA, it is difficult for the children to practice a sport.</p>
<disp-quote>
<p><italic>"It&#x2019;s like a vicious circle. Parents don&#x2019;t do any PA and in the end the children don&#x2019;t do any PA either. And since the children don&#x2019;t do anything, the parents don&#x2019;t practice either."</italic> (Teacher#0013#).</p>
</disp-quote>
<p>Another important point stressed by participants was the excessive protection of the families towards girls in relation to boys, when carrying out any type of extracurricular activity. Boys are allowed to move with greater freedom than girls. This perception of the protectionism of families towards girls was observed specifically in the Maghrebi and Asian communities. The participants agreed that the family may perpetuate certain social and cultural stereotypes that place girls at a disadvantage when practicing PA. In addition, the participants pointed out that often the responsibility for the child&#x2019;s education falls mainly on the mother, due to the physical absence of the father. This means that, in addition to the responsibility of supporting and caring for the rest of the family, the mother relies on the daughters&#x2019; help for the performance of household chores or to support in the family business.</p>

<sec id="c3-s3-s3-s1-s5">
<label>3.1.5.</label>
<title>Religious Beliefs and Practices</title>
<p>The teachers reported that in some communities, religious practices can hamper or limit the practice of PA for girls, particularly in the Maghrebi community. From the <target target-type="page" id="pges_80"/>participants &#x2018;perspective, while there are some sports practices that Maghrebi girls can perform with greater or lesser comfort due to the use of other types of clothing, not strictly sportswear, certain sports may cause conflicts with families, such as swimming.</p>
<p>The participants felt that some families may prioritize certain religious practices or religious interpretations over their daughters&#x2019; education and learning. This is accentuated during menstruation, as girls begin to wear certain clothes according to their religious beliefs, and in some there is a rejection of PA, sometimes motivated by stereotypes about PA.</p>

<sec id="c3-s3-s3-s1-s6">
<label>3.1.6.</label>
<title>Gender Differences</title>
<p>The teachers reported that there are marked gender roles for the practice of PA. Thus, certain sports are considered to be more suited to boys or girls, especially among the North African and South American communities.</p>

<p>The participants explained that the physical condition of immigrant girls was poorer compared to their Spanish counterparts, in addition to difficulties in hand-eye coordination, rhythm and motor skills. This was especially related to girls from the Maghrebi and Asian communities. The teachers explained the subject of PE in the young girls&#x2019; countries of origin was less intense, and that some girls had never developed a habit for practicing sports. In the interviews, the low level of physical fitness only referred to the female population; the participants did not make any comments regarding the boys.</p>
<p>The participants explained that some girls choose to exclude themselves from practicing PA, even during recess or free time, leaving the physical space of the school (playgrounds) to allow the boys to practice PA. The teachers felt that girls perceive themselves as clumsier, or with less skills or abilities than boys. Sometimes girls are even ignored during PE classes or recess when sharing games or sports activities with them.</p>
<p>Some participants believed that the family is not supportive of girls practicing PA, through overprotective attitudes, cultural reasons or religious beliefs.</p>

<title><italic>Results of Emotions and the Polarity (Acceptance-Rejection) Analysis</italic></title>
<p>The sentiment analysis regarding the research questions showed a prevalence of positive emotions (<xref ref-type="fig" rid="c3-s3-fig2">Figure 2A,B</xref>). In contrast, according to the Afinn dictionary there is a slight predominance of negative emotions, especially scores of &#x2014;1, against positive scores of 1 and 2 (<xref ref-type="fig" rid="c3-s3-fig2">Figure 2C</xref>). The associated emotions are those of trust and anticipation, followed by fear and joy (<xref ref-type="fig" rid="c3-s3-fig2">Figure 2A</xref>).</p>

<title><bold>Discussion</bold></title>
<p>Our findings highlight that, according to the perspective of PE teachers, the educational level of immigrant parents can influence their children&#x2019;s PA. The survey on the immigrant population in the community of Madrid in 2016 [<xref ref-type="bibr" rid="ref.3.2.41">41</xref>] shows that 30% of the immigrant population presented a basic level of education. In Spain, the 2017 national health survey [<xref ref-type="bibr" rid="ref.3.2.42">42</xref>] described that the practice of PA was inversely proportional to the families&#x2019; level of education. The authors believe that a low level of education could explain a lack of awareness of the benefits of PA on the child&#x2019;s health and development. The participants in the present study perceived how immigrant families linked PA to leisure and entertainment, giving more importance to other subjects. Along this line, Trigwell et al. [<xref ref-type="bibr" rid="ref.3.2.43">43</xref>], show how families from different ethnic communities prioritize educational achievement (based on subjects such as mathematics, science) over PA.</p>
<p>Our results show how family finances can influence the ability to engage in certain physical-sports activities. There are no published data to date on the enrollment of immigrant children and youth in IPAFD programs. The national survey of immigrants in Spain [<xref ref-type="bibr" rid="ref.3.2.44">44</xref>] describes that 40% of the immigrant population perform manual or low-skilled jobs, and 22% perform manual jobs that require specific prior training. This emphasizes that many immigrants hold precarious jobs, with low incomes and long working hours. The authors believe that families enter a vicious circle, where the lower the level of education, the less qualified and less well paid the work is, resulting in a lack of sufficient economic resources to enroll their children in extracurricular sports activities, and a decreased practice of PA.</p>
<p>Physical education and sport are important tools in the process of integrating people into society. Lleix&#x00E0; [<xref ref-type="bibr" rid="ref.3.2.45">45</xref>] describes how PE is a space for meeting and communication that promotes the relationship between people from different cultures. According to the UNESCO, one of the objectives of PE and sport is to promote proximity between people and individuals [<xref ref-type="bibr" rid="ref.3.2.46">46</xref>]. In addition, the International Federation of Physical Education [<xref ref-type="bibr" rid="ref.3.2.47">47</xref>] establishes that PE must be a means of combating discrimination and social exclusion. Previous studies [<xref ref-type="bibr" rid="ref.3.2.48">48</xref>] show how certain communities may have a more isolated character and less interaction with other communities. Acculturation or assimilation of the host culture of immigrant families is related to the integration of children into society and can be <target target-type="page" id="pges_83"/>a factor in the acquisition of habits, such as the practice of PA [<xref ref-type="bibr" rid="ref.3.2.49">49</xref>,<xref ref-type="bibr" rid="ref.3.2.50">50</xref>] Gerber et al. [<xref ref-type="bibr" rid="ref.3.2.49">49</xref>] point out that the higher the degree of acculturation of people in a new society, or the longer the stay in the country, the greater the possibilities of practicing PA. Moreover, the lower the level of acculturation in the population, the lower their participation in PA [<xref ref-type="bibr" rid="ref.3.2.51">51</xref>-<xref ref-type="bibr" rid="ref.3.2.53">53</xref>].</p>
<p>Additionally, there are differences between children and adolescents concerning their attitude towards PE lessons. Previous studies report that interest towards PA practice and PE decreases as students get older [<xref ref-type="bibr" rid="ref.3.2.54">54</xref>-<xref ref-type="bibr" rid="ref.3.2.56">56</xref>]. G&#x00F3;mez Rijo et al. [<xref ref-type="bibr" rid="ref.3.2.56">56</xref>] describe how the motivation of adolescents in secondary education towards PE practice is lower than that of primary school students. According to Fraile Aranda &#x0026; Catalina Sancho [<xref ref-type="bibr" rid="ref.3.2.57">57</xref>], primary school students tend to feel more skillful at a sporting level than secondary school students. Overall, secondary students have a lower self-concept regarding their ability to perform PA compared to younger students [<xref ref-type="bibr" rid="ref.3.2.57">57</xref>].</p>
<p>Among teachers, there are also differences in their perception and orientation towards PA in primary and secondary education influenced by the school curriculum [<xref ref-type="bibr" rid="ref.3.2.58">58</xref>,<xref ref-type="bibr" rid="ref.3.2.59">59</xref>]. Primary PE teachers orientate learning towards attitudinal and self-realization goals, while secondary school teachers give more importance to procedural and conceptual learning, developing a greater social responsibility [<xref ref-type="bibr" rid="ref.3.2.58">58</xref>]. As a result, primary school teachers are more oriented towards games and global developmental work, while secondary school teachers are oriented towards more social skills development. However, Sicilia Camacho et al. [<xref ref-type="bibr" rid="ref.3.2.59">59</xref>] point out that in primary education, priority should be given to the development of social relations whereas in secondary education the focus should be on the acquisition of healthy habits.</p>
<p>Another key point is the role of parents as role models for PA practice. Previous studies [<xref ref-type="bibr" rid="ref.3.2.60">60</xref>,<xref ref-type="bibr" rid="ref.3.2.61">61</xref>] show how parents are an influence on adherence to PA. The more PA practiced by parents in their free time, the more likely their children are to develop similar habits. The authors believe that when parents practice PA, the family has a positive attitude towards PA and the subject of PE, and this can facilitate the practice of PA in their children. However, it should be emphasized that cultural components and/or beliefs can condition PA, particularly in the case of women. This may lead to the existence of a cultural conception of motor activity or motor development in children that is different from that of girls and boys [<xref ref-type="bibr" rid="ref.3.2.48">48</xref>,<xref ref-type="bibr" rid="ref.3.2.62">62</xref>]. Previous studies [<xref ref-type="bibr" rid="ref.3.2.18">18</xref>,<xref ref-type="bibr" rid="ref.3.2.63">63</xref>] describe how immigrant girls present a lower level of physical condition and less motor skills when it comes to collective activities, which may result in inhibition and self-exclusion from the sports space.</p>
<p>Most of the participants described religious beliefs as a possible barrier to the practice of PA, in relation to girls from the Maghrebi community. Capllonch et al. [<xref ref-type="bibr" rid="ref.3.2.64">64</xref>] describe how certain religious beliefs may limit the practice of PA among female members of the community, aspects such as exposing naked body parts (swimming, athletics), training or sharing PA with males, could prevent girls from participating in sports activities [<xref ref-type="bibr" rid="ref.3.2.61">61</xref>,<xref ref-type="bibr" rid="ref.3.2.65">65</xref>]. Moreover, previous studies [<xref ref-type="bibr" rid="ref.3.2.62">62</xref>] have stressed the need for teacher training on the reality of immigration and especially on the understanding of the cultural aspects of the Maghrebi and Muslim communities. Dagkas et al. [<xref ref-type="bibr" rid="ref.3.2.62">62</xref>] in England, describe how PA practice can be adapted for Maghrebi girls while respecting cultural and religious precepts and complying with school rules.</p>
<p>According to our findings, teachers report that girls show less initiative for practicing PA. In Spain, Mart&#x00ED;nez Baena et al. [<xref ref-type="bibr" rid="ref.3.2.66">66</xref>] describe how in students over 13 years of age, 23.1% of the girls practiced PA through obligation, whereas 15.7% acknowledged that they did not practice PA out of laziness. In addition, Flores [<xref ref-type="bibr" rid="ref.3.2.48">48</xref>], in a study on multicultural reality and PE teachers, described how immigrant girls claimed to have very little interest and passivity towards the subject of PE.</p>
<p>Regarding differences in teachers&#x2019; and parents&#x2019; perspectives on PE, Porcuna &#x0026; Rodr&#x00ED;guez-Mart&#x00ED;n [<xref ref-type="bibr" rid="ref.3.2.67">67</xref>] reported that both parents and teachers agree that they can act as role models for children and adolescents, which can positively and negatively influence them to practice PA. Similarly, they agree that there are environmental barriers to PA, such as high workloads, lack of parental time, or the lack of spaces where PA can be carried out [<xref ref-type="bibr" rid="ref.3.2.67">67</xref>]. However, in the same <target target-type="page" id="pges_84"/>study, Porcuna &#x0026; Rodr&#x00ED;guez-Mart&#x00ED;n [<xref ref-type="bibr" rid="ref.3.2.67">67</xref>] described that while teachers demanded greater collaboration between parents and teachers, parents demanded to receive more information from teachers on how to promote PA outside the school context [<xref ref-type="bibr" rid="ref.3.2.67">67</xref>]. Similarly, from the parents&#x2019; perspective, sex and gender are identified as determining factors in the practice of PA [<xref ref-type="bibr" rid="ref.3.2.10">10</xref>,<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>,<xref ref-type="bibr" rid="ref.3.2.20">20</xref>], along with economic barriers and lack of infrastructure for PA [<xref ref-type="bibr" rid="ref.3.2.15">15</xref>-<xref ref-type="bibr" rid="ref.3.2.17">17</xref>].</p>
<p>It should be noted that of the three dictionaries used to identify the participants&#x2019; feelings towards the research questions, two show a positive tendency in their discourse on PA and immigrant children and youth. Only one of the dictionaries used, Afinn, showed negative feelings, but with a percentage very close to positivity. Even though the teachers in the thematic analysis displayed a critical view of the practice of PA in immigrant children, identifying numerous barriers, their discourse tended to be positive, based on the text analysis carried out.</p>
<p>The results of this study reveal the perspective of PE teachers on aspects that may condition the practice of PA in immigrant children and adolescents. This perspective is the object of the study; however, it does not mean that it represents, coincides with or is contrary to the perspective or beliefs of other participants involved in the practice of PA, such as parents and students. This study has several limitations. First, a small number of participants were included. The present study has included 20 participants. Previous qualitative studies [<xref ref-type="bibr" rid="ref.3.2.25">25</xref>,<xref ref-type="bibr" rid="ref.3.2.30">30</xref>] describe how the total number of participants included does not depend on a previous calculation of the sample size; rather, it is based on the saturation or redundancy of the information obtained in the interviews. Turner-Bowker et al. [<xref ref-type="bibr" rid="ref.3.2.68">68</xref>] reported that 92-97% of the saturation can be analyzed after interview number 15 and 20. Secondly, the teachers included in the study were not part of the liaison classrooms, classrooms intended for the support and adaptation of immigrant children/adolescents joining the school. This could influence the results. In addition, teachers were not asked about the process of teaching PE to children and adolescents, which may reveal differences in the performance of PA. Finally, the qualitative nature of this study, gathering the perspective and experiences of a group of PE teachers concerning a certain phenomenon, cannot be generalized. However, it allows us to gain a deeper understanding of the phenomenon from their perspective.</p>

<title><bold>Conclusions</bold></title>
<p>Our findings help further our understanding of the barriers related to PA in immigrant children and youth in Spain such as giving more importance to certain subjects because of their job prospects, having low economic resources, the lack of role models in the family for the practice of PA, the formation of closed groups for PA practice among students, and the limitation of PA in girls due to gender differences. One of the strengths of this study is that it describes the barriers for performing PA among immigrant children from the perspective of the PE teachers.</p>
<p>Concerning the implications for teaching, these findings may help PE teachers to identify elements such as family issues, beliefs, and economical issues that can condition PA. Furthermore, these results can help young or inexperienced teachers to plan and program the teaching of PE towards the needs of immigrant pupils by promoting greater participation, considering their possible limitations and perspectives. Further, these findings may be considered for the design and implementation of PA programs in certain social contexts. It is important for PA programs to: (a) analyze the academic curriculum and devote increased time to PA, (b) provide financial support to families who have limited resources in order to cover any associated costs related to children&#x2019;s sports practice, and (c) promote the organization of sports activities and multicultural games in community settings.</p>
<p>Future lines of research should include the perspective of other participants, such as students and parents, regarding PA. In addition, it is important to examine the barriers for practicing PA in different contexts (school environment, neighborhood), and identify any obstacles for the practice of PA among immigrant students of different nationalities, also from a gender perspective.</p>

<title>Discusi&#x00F3;n de los resultados</title>
<p>Con la presente tesis, se han identificado barreras para la promoci&#x00F3;n de la AF en los ni&#x00F1;os y j&#x00F3;venes inmigrantes. Esas barreras han sido percibidas y narradas por las madres y padres, los profesores de EF, directores de los centros escolares y por l&#x00ED;deres religiosos de su entorno.</p>
<p>Esta tesis contin&#x00FA;a una l&#x00ED;nea de investigaci&#x00F3;n sobre los factores que impactan e influyen en la pr&#x00E1;ctica de la AF y la implementaci&#x00F3;n de un estilo de vida saludable en ni&#x00F1;os inmigrantes (<xref ref-type="bibr" rid="CIT138">Masoumi, 2017</xref>; <xref ref-type="bibr" rid="CIT188">Taverno Ross et al., 2018</xref>; <xref ref-type="bibr" rid="CIT198">Trigwell et al., 2015</xref>). Estudios anteriores sobre la AF en ni&#x00F1;os y adolescentes (<xref ref-type="bibr" rid="CIT026">Bhatnagar et al., 2015</xref>; <xref ref-type="bibr" rid="CIT035">Brewer &#x0026; Kimbro, 2014</xref>; <xref ref-type="bibr" rid="CIT082">Gualdi-Russo et al., 2014</xref>; <xref ref-type="bibr" rid="CIT113">Labree et al., 2014</xref>; <xref ref-type="bibr" rid="CIT136">Mart&#x00ED;nez-Andr&#x00E9;s et al., 2020</xref>; <xref ref-type="bibr" rid="CIT149">Mude &#x0026; Mwanri, 2016</xref>) muestran c&#x00F3;mo los ni&#x00F1;os y adolescentes que proceden de familia inmigrante practicaban menos AF en comparaci&#x00F3;n con los ni&#x00F1;os y adolescentes nativos.</p>
<p>Los estudios uno (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) y dos (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) muestran como las familias de los ni&#x00F1;os inmigrantes reconocen que existe una desigualdad por sexo de pr&#x00E1;ctica de la AF entre los ni&#x00F1;os y las ni&#x00F1;as. Estos resultados vuelven aparecer en el estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>), donde los profesores reconocen que la pr&#x00E1;ctica de AF y su aplicaci&#x00F3;n es diferente entre sexos. La existencia de desigualdad en la pr&#x00E1;ctica de AF entre sexos puede considerarse como un fen&#x00F3;meno global (<xref ref-type="bibr" rid="CIT004">Althoff et al., 2017</xref>). Estudios previos (<xref ref-type="bibr" rid="CIT182">Sharara et al., 2018</xref>; <xref ref-type="bibr" rid="CIT198">Trigwell et al., 2015</xref>) muestran que esta diferencia de g&#x00E9;nero existe en el recreo donde varia la cantidad de AF as&#x00ED; como el tipo de AF realizada. Los participantes profesores del estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) adem&#x00E1;s a&#x00F1;aden que las creencias religiosas pueden ser una barrera a la pr&#x00E1;ctica de AF, sobre todo en las ni&#x00F1;as de la comunidad magreb&#x00ED;. <xref ref-type="bibr" rid="CIT042">Capllonch et al. (2007)</xref> describen c&#x00F3;mo ciertas creencias religiosas pueden limitar la pr&#x00E1;ctica de AF entre los miembros femeninos de la comunidad. Adem&#x00E1;s estudios anteriores (<xref ref-type="bibr" rid="CIT071">Flores Aguilar, Prat Grau, &#x0026; Soler Prat, 2016</xref>; <xref ref-type="bibr" rid="CIT103">Jord&#x00E1;n, 2007</xref>) describen que las ni&#x00F1;as inmigrantes presentan un menor nivel de condici&#x00F3;n f&#x00ED;sica y menos habilidades motrices a la hora de realizar actividades colectivas, lo que puede suponer una inhibici&#x00F3;n y autoexclusi&#x00F3;n del espacio deportivo.</p>
<p>La EF y el deporte son herramientas importantes en el proceso de integraci&#x00F3;n de las personas en la sociedad. <xref ref-type="bibr" rid="CIT125">Lleix&#x00E0; Arribas (2006)</xref> describe c&#x00F3;mo la EF es un espacio de encuentro y comunicaci&#x00F3;n que favorece la relaci&#x00F3;n entre personas de diferentes culturas. Seg&#x00FA;n la <xref ref-type="bibr" rid="CIT200">UNESCO (2021)</xref> uno de los objetivos de la EF y del deporte es promover la proximidad entre las personas y los <target target-type="page" id="pges_90"/>individuos. Adem&#x00E1;s, la Federaci&#x00F3;n Internacional de Educaci&#x00F3;n F&#x00ED;sica (<xref ref-type="bibr" rid="CIT068">FIEP, 2000</xref>) establece que la educaci&#x00F3;n f&#x00ED;sica debe ser un medio para luchar contra las discriminaciones y la exclusi&#x00F3;n social. En el estudio dos (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>), los padres percibieron que la AF tiene un efecto socializador importante en la vida de sus hijos en la nueva vida que les ofrece la inmigraci&#x00F3;n. La aculturaci&#x00F3;n de la familia pasa tambi&#x00E9;n por la integraci&#x00F3;n social de los ni&#x00F1;os en la escuela y en particular por la pr&#x00E1;ctica de AF en la asignatura de EF. Existe un enfoque similar en el estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) desde la perspectiva de los profesores de EF. Para ellos, la AF y la EF (en particular) son herramientas importantes para permitir la integraci&#x00F3;n de los j&#x00F3;venes inmigrantes en la nueva sociedad en la cual viven y puede ser un factor importante de adquisici&#x00F3;n de h&#x00E1;bitos saludables, como es la pr&#x00E1;ctica regular de una AF. <xref ref-type="bibr" rid="CIT076">Gerber, Barker, &#x0026; P&#x00FC;hse (2012)</xref> se&#x00F1;alan que cuanto mayor es el grado de aculturaci&#x00F3;n de las personas en una sociedad mayores son las posibilidades de pr&#x00E1;ctica de AF. Por lo que cuanto menor es el nivel de aculturaci&#x00F3;n de la poblaci&#x00F3;n, menor es su participaci&#x00F3;n en las AF (<xref ref-type="bibr" rid="CIT035">Brewer &#x0026; Kimbro, 2014</xref>; <xref ref-type="bibr" rid="CIT082">Gualdi-Russo et al., 2014</xref>; <xref ref-type="bibr" rid="CIT225">Yi, Roberts, Lightstone, Shih, &#x0026; Trinh-Shevrin, 2015</xref>).</p>
<p>La influencia de los padres y madres podr&#x00ED;a ser una explicaci&#x00F3;n a la baja participaci&#x00F3;n de los j&#x00F3;venes inmigrantes en la AF. Estudios anteriores (<xref ref-type="bibr" rid="CIT007">Andermo, Rydberg, &#x0026; Norman, 2021</xref>; <xref ref-type="bibr" rid="CIT037">Bringolf-Isler et al., 2018</xref>; <xref ref-type="bibr" rid="CIT079">Grant, Swaney, Harris, Burdeau, &#x0026; Brown, 2016</xref>; <xref ref-type="bibr" rid="CIT153">Neshteruk et al., 2017</xref>) han examinado la influencia de los padres en la AF de los ni&#x00F1;os. El grupo de estudio SOPHYA (<xref ref-type="bibr" rid="CIT037">Bringolf-Isler et al., 2018</xref>) inform&#x00F3; como la adquisici&#x00F3;n de modelos parentales frente a la AF es relevante para la pr&#x00E1;ctica de AF de los ni&#x00F1;os/as. Por lo que el estudio dos (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) subraya la importancia de conocer las perspectivas de la familia (padres y madres) respeto a la AF ya que padres y madres desempe&#x00F1;an un papel crucial en la determinaci&#x00F3;n de las conductas sedentarias de sus hijos. En el estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) los profesores de EF, muestran que la actitud de las familias frente a la AF es fundamental. Dar el ejemplo a sus hijos es un paso obligado para que los ni&#x00F1;os y j&#x00F3;venes tengan una AF regular con el objetivo de tener un comportamiento de h&#x00E1;bitos saludables En una investigaci&#x00F3;n cualitativa reciente (<xref ref-type="bibr" rid="CIT179">Satija et al., 2018</xref>) los j&#x00F3;venes describen como los padres activos son un factor positivo que aumenta la motivaci&#x00F3;n para una pr&#x00E1;ctica de AF. Varios estudios (<xref ref-type="bibr" rid="CIT130">Malek, Nyberg, Elinder, Patterson, &#x0026; Norman, 2021</xref>; <xref ref-type="bibr" rid="CIT143">Mittal &#x0026; Jain, 2021</xref>; <xref ref-type="bibr" rid="CIT194">Tomayko et al., 2021</xref>) muestran la importancia que tiene de integrar a los padres en proyectos educativos para la prevenci&#x00F3;n de h&#x00E1;bitos saludables en los j&#x00F3;venes y un control de la obesidad. Por lo que la organizaci&#x00F3;n de la vida familiar es otro punto clave para la adquisici&#x00F3;n de h&#x00E1;bitos saludables. Las interacciones familiares y el tiempo pasado juntos a trav&#x00E9;s de comidas y cenas en familia son factores claves para la salud familiar en t&#x00E9;rminos de nutrici&#x00F3;n y de AF (<xref ref-type="bibr" rid="CIT207">W&#x00E4;sche, Niermann, Bezold, &#x0026; Woll, 2021</xref>) y tiene consecuencias en los comportamientos individuales de sus miembros. <target target-type="page" id="pges_91"/>El tercer art&#x00ED;culo (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) adem&#x00E1;s, se describe la perspectiva de los profesores en relaci&#x00F3;n con el nivel educativo de los padres y madres y su posible repercusi&#x00F3;n en la AF. Los profesores creen que un bajo nivel educativo de los padres y madres inmigrantes influye sobre la AF de sus hijos lo que completa la informaci&#x00F3;n inicial avanzado en el art&#x00ED;culo uno (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) que los padres y madres son modelo parental que seguir por los ni&#x00F1;os.</p>
<p>Otro punto importante y recurrente en los tres estudios realizados (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT133">2020</xref>, <xref ref-type="bibr" rid="CIT134">2021</xref>) es el nivel socioecon&#x00F3;mico de las familias inmigrantes. En los tres art&#x00ED;culos (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT133">2020</xref>, <xref ref-type="bibr" rid="CIT134">2021</xref>) tanto las familias como profesores explican que un nivel socioecon&#x00F3;mico bajo limita la pr&#x00E1;ctica de AF. En el estudio dos (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) las familias describen como el cambio de pa&#x00ED;s se realiza principalmente por razones de mejora del nivel econ&#x00F3;mico de la familia, por lo que la pr&#x00E1;ctica de AF no es prioridad para ellos. Tambi&#x00E9;n, muchas familias muestran que la falta de recurso econ&#x00F3;micos es un freno a la pr&#x00E1;ctica de AF para sus hijos. Los padres y madres explican que la pr&#x00E1;ctica de AF tiene un coste, por un lado, econ&#x00F3;mico (compra de ropa y material deportivo) y por otro lado, por el tiempo que se debe dedicar a la pr&#x00E1;ctica de AF por sus hijos/as. Estudios anteriores (<xref ref-type="bibr" rid="CIT077">Gonzalo-Almorox &#x0026; Urbanos-Garrido, 2016</xref>; <xref ref-type="bibr" rid="CIT145">Molina-Garc&#x00ED;a et al., 2017</xref>) demuestran que un nivel socioecon&#x00F3;mico menor, disminuye la posibilidad de pr&#x00E1;ctica deportiva. Por lo que los profesores explican en el estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>), que los programas deportivos extraescolares (IPAFD) est&#x00E1;n m&#x00E1;s concurrido por la poblaci&#x00F3;n inmigrante que por la poblaci&#x00F3;n aut&#x00F3;ctona. Los profesores explican que el precio de esos programas y la facilidad de compaginarlo con la vida laboral de los padres hace que se apuntan principalmente alumnos de origen inmigrante o con nivel socioecon&#x00F3;mico bajo. Por lo que, para muchas familias y j&#x00F3;venes, los programas IPAFD son los &#x00FA;nicos momentos donde pueden practicar una AF extraescolar.</p>
<p>En los estudios uno y dos (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT133">2020</xref>), los participantes muestran que los barrios donde viven no presentan las condiciones id&#x00F3;neas, ni cuentan con las infraestructuras necesarias para la pr&#x00E1;ctica de AF. Los padres y madres del estudio dos (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) explican que existe una falta de parques, instalaciones deportivas o de ocio. El entorno f&#x00ED;sico, con grandes parques o espacios naturales es un factor clave para una buena pr&#x00E1;ctica f&#x00ED;sica. Estudios anteriores (<xref ref-type="bibr" rid="CIT053">Creatore et al., 2016</xref>; <xref ref-type="bibr" rid="CIT138">Masoumi, 2017</xref>; <xref ref-type="bibr" rid="CIT203">van Sluijs et al., 2021</xref>) muestran c&#x00F3;mo el barrio, la zona de la ciudad en la que se encuentran, la presencia de parques, el transporte urbano accesible y la planificaci&#x00F3;n urbana integral de apoyo a la AF (<italic>walkability</italic>) influyen en la realizaci&#x00F3;n de AF. Sin embargo, en el estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>), los profesores no creen que en los barrios donde viven las familias inmigrantes (Zona sur de Madrid) sean barrios con problemas de infraestructuras deportivas o de parques de ocio. Los profesores <target target-type="page" id="pges_92"/>expresan que existe muchas infraestructuras deportivas, gimnasios (incluso <italic>LowCost</italic>), parques, zonas deportivas al aire libre o polideportivos. Las perspectivas entre las familias (estudio 1 y 2) y los profesores de EF (del estudio 3) son diferentes en este punto. Los profesores insisten m&#x00E1;s bien sobre los problemas econ&#x00F3;micos de las familias a acudir a dichos centros o en las dificultades de conciliaci&#x00F3;n familiares entre las horas de trabajo y el cuidado de los hijos. Los profesores del estudio tres (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) est&#x00E1;n de acuerdo en que las familias inmigrantes tienen una falta de tiempo por razones laborales. Esa falta de tiempo es compartida por los padres y madres del estudio uno y dos (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT133">2020</xref>), que describen una incompatibilidad con sus horarios de trabajo y el ritmo familiar. Estudios anteriores (<xref ref-type="bibr" rid="CIT136">Mart&#x00ED;nez-Andr&#x00E9;s et al., 2020</xref>; <xref ref-type="bibr" rid="CIT175">Sallis &#x0026; Mota, 2002</xref>; <xref ref-type="bibr" rid="CIT181">Serra Puyal, Generelo Lanaspa, &#x0026; Zaragosa Casterad, 2010</xref>) afirman que las cargas de trabajo y familiares pueden impedir que los ni&#x00F1;os y los padres y madres practiquen AF.</p>
<p>Por &#x00FA;ltimo, recientemente, el mundo est&#x00E1; afrontando una crisis de salud debido al virus SARS-CoV-2, conocido como COVID-19, identificado por primera vez en Wuhan, China en diciembre del a&#x00F1;o 2019 (<xref ref-type="bibr" rid="CIT228">Zhu et al., 2020</xref>). El 12 de marzo del 2020, la OMS declar&#x00F3; la pandemia mundial por el COVID-19 (<xref ref-type="bibr" rid="CIT218">World Health Organization, 2020a</xref>). Desde entonces se han producido muchos cambios debido a las medidas de confinamiento y de control del contagio que han podido influir en la pr&#x00E1;ctica de AF en ni&#x00F1;os y j&#x00F3;venes (<xref ref-type="bibr" rid="CIT086">Hao et al., 2021</xref>; <xref ref-type="bibr" rid="CIT154">Nieuwenhuijsen, 2021</xref>). Un estudio reciente (<xref ref-type="bibr" rid="CIT209">Weaver, Tassitano, Ten&#x00F3;rio, Brazendale, &#x0026; Beets, 2021</xref>) hab&#x00ED;a mostrado que el tiempo de AF durante el tiempo escolar hab&#x00ED;a aumentado desde 2015 y hasta 2019 despu&#x00E9;s de una d&#x00E9;cada de regresi&#x00F3;n de tiempo activo en las escuelas. Sin embargo, la llegada de la pandemia de COVID-19 ha tenido consecuencias sobre estos resultados motivadores. La pr&#x00E1;ctica de AF de los j&#x00F3;venes se ha visto afectado con consecuencias en varios &#x00E1;mbitos, como el aumento del sedentarismo (<xref ref-type="bibr" rid="CIT061">Dunton, Do, &#x0026; Wang, 2020</xref>), aumento del tiempo de pantalla (<xref ref-type="bibr" rid="CIT180">Schmidt et al., 2020</xref>), aumentos de s&#x00ED;ntomas de ansiedad, depresi&#x00F3;n (<xref ref-type="bibr" rid="CIT005">Alves, Yunker, DeFendis, Xiang, &#x0026; Page, 2020</xref>) o un descenso en la calidad del sue&#x00F1;o (<xref ref-type="bibr" rid="CIT020">Bates et al., 2020</xref>). Varios estudios (<xref ref-type="bibr" rid="CIT041">Cach&#x00F3;n-Zagalaz, Zagalaz-S&#x00E1;nchez, Arufe-Gir&#x00E1;ldez, Sanmiguel-Rodr&#x00ED;guez, &#x0026; Gonz&#x00E1;lez-Valero, 2021</xref>; <xref ref-type="bibr" rid="CIT061">Dunton et al., 2020</xref>; <xref ref-type="bibr" rid="CIT180">Schmidt et al., 2020</xref>) han mostrado que las reglas de confinamiento impuestos han tenido repercusi&#x00F3;n en una diminuci&#x00F3;n del tiempo de pr&#x00E1;ctica de AF (<xref ref-type="bibr" rid="CIT003">Alonso-Mart&#x00ED;nez, Ram&#x00ED;rez-V&#x00E9;lez, Garc&#x00ED;a-Alonso, Izquierdo, &#x0026; Garc&#x00ED;a-Hermoso, 2021</xref>). El estudio de <xref ref-type="bibr" rid="CIT003">Alonso-Mart&#x00ED;nez et al. (2021)</xref> ha mostrado una diminuci&#x00F3;n de hasta 43,3 min menos de tiempo de AF diaria, una eficacidad del sue&#x00F1;o de -2,09% y un aumento de 50,2 minutos de tiempo de pantalla al d&#x00ED;a en ni&#x00F1;os de 4 a 6 a&#x00F1;os. El estudio de <xref ref-type="bibr" rid="CIT223">Wunsch et al. (2021)</xref> informa que los j&#x00F3;venes que ten&#x00ED;an una AF regular antes de la COVID-19 ten&#x00ED;an menos riesgos de ser inactivos durante la pandemia. Tambi&#x00E9;n explican que los ni&#x00F1;os que ten&#x00ED;an un tiempo de pantalla importante antes de la COVID-19 eran propensos a aumentar sus tiempos de <target target-type="page" id="pges_93"/>pantalla y en realizar menos AF. Los estudios uno y tres (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT134">2021</xref>) muestran una percepci&#x00F3;n de realizaci&#x00F3;n de AF bajo, por lo que los ni&#x00F1;os y/o j&#x00F3;venes inmigrantes durante la pandemia podr&#x00ED;an haber sufrido un descenso en sus niveles de AF previos. En Espa&#x00F1;a, (<xref ref-type="bibr" rid="CIT140">Medrano et al., 2021</xref>) han descrito un descenso en la AF en ni&#x00F1;os de entre 8 y 16 a&#x00F1;os con padres de origen extranjero. Adem&#x00E1;s, que los padres y/o madres tuvieran un nivel de estudio no universitarios presentaban riesgos m&#x00E1;s elevados de una menor AF diaria durante la pandemia de COVID-19. Por otro lado, varios estudios cualitativos (<xref ref-type="bibr" rid="CIT009">Andriyani, Biddle, &#x0026; De Cocker, 2021</xref>; <xref ref-type="bibr" rid="CIT048">Clarke et al., 2021</xref>) sobre las consecuencias de la pandemia, describen como los padres percib&#x00ED;an que sus hijos practicaban menos AF durante el confinamiento. (<xref ref-type="bibr" rid="CIT162">Pelletier, Cornish, &#x0026; Sanders, 2021</xref>) describen como los progenitores, identificaron como sus hijos ten&#x00ED;an menos contacto social, con amigos o familiares. Los padres y/o madres y profesores de EF de los estudios uno, dos y tres (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>, <xref ref-type="bibr" rid="CIT133">2020</xref>, <xref ref-type="bibr" rid="CIT134">2021</xref>) narraban como identificaban dificultades en las relaciones sociales y pr&#x00E1;ctica de AF como elemento de socializaci&#x00F3;n, entre los ni&#x00F1;os y j&#x00F3;venes de origen inmigrante, pudiendo haber empeorado durante la pandemia de la COVID-19. El estudio de <xref ref-type="bibr" rid="CIT093">Idoiaga Mondragon et al. (2021)</xref> muestra como los j&#x00F3;venes declaran que ha sido complicado mantener contacto social con sus amigos y familiares y que eso limitaba alguna de las actividades que realizaban como AF.</p>

<title>Discusi&#x00F3;n de los dise&#x00F1;os utilizados y criterios de calidad de los estudios cualitativos en ciencias de la salud</title>
<p>La presente tesis doctoral mediante compendio de art&#x00ED;culos est&#x00E1; formada por tres estudios, cuyos dise&#x00F1;os son cualitativos. En el primer art&#x00ED;culo (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) el dise&#x00F1;o fue un estudio de casos cualitativo y descriptivo con unidades integradas (<xref ref-type="bibr" rid="CIT054">Creswell &#x0026; Poth, 2018</xref>; <xref ref-type="bibr" rid="CIT226">Yin, 2014</xref>). Un estudio de casos puede estar formado por diferentes unidades que ayudan a describir un fen&#x00F3;meno. Estas unidades pueden ser diferentes participantes de diferentes contextos y lugares que s&#x00F3;lo est&#x00E1;n conectados por el fen&#x00F3;meno estudiado (<xref ref-type="bibr" rid="CIT044">Carolan, Forbat, &#x0026; Smith, 2016</xref>; <xref ref-type="bibr" rid="CIT054">Creswell &#x0026; Poth, 2018</xref>; <xref ref-type="bibr" rid="CIT226">Yin, 2014</xref>). En este estudio, el fen&#x00F3;meno objeto de estudio fueron las barreras para la promoci&#x00F3;n de la actividad f&#x00ED;sica en los ni&#x00F1;os inmigrantes, percibidas por diferentes participantes, entre los que se encontraban los padres, los profesores, el director de un colegio y los l&#x00ED;deres de la comunidad social. En el Segundo articulo (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) el dise&#x00F1;o fue un estudio de caso cualitativo y exploratorio, que utiliza un paradigma interpretativo (<xref ref-type="bibr" rid="CIT054">Creswell &#x0026; Poth, 2018</xref>). Un estudio de casos es un dise&#x00F1;o de investigaci&#x00F3;n que implica el examen de un fen&#x00F3;meno contempor&#x00E1;neo en un entorno real (<xref ref-type="bibr" rid="CIT066">F&#x00E0;bregues &#x0026; Fetters, 2019</xref>). Se utiliza para explorar y describir un &#x00FA;nico caso limitado en el tiempo y el lugar (es decir, la perspectiva de los padres respecto a la actividad f&#x00ED;sica de sus hijos). Adem&#x00E1;s, un estudio de casos cualitativo puede utilizarse para <target target-type="page" id="pges_94"/>describir las experiencias de los participantes en relaci&#x00F3;n con la atenci&#x00F3;n, el cambio de pol&#x00ED;ticas y para comprender por qu&#x00E9; los comportamientos y las intervenciones complejas tienen &#x00E9;xito o fracasan (<xref ref-type="bibr" rid="CIT066">F&#x00E0;bregues &#x0026; Fetters, 2019</xref>). Finalmente, en el tercer articulo (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>), se utiliz&#x00F3; un dise&#x00F1;o exploratorio cualitativo (<xref ref-type="bibr" rid="CIT054">Creswell &#x0026; Poth, 2018</xref>; <xref ref-type="bibr" rid="CIT108">Korstjens &#x0026; Moser, 2017</xref>). Los estudios cualitativos se utilizan para describir las experiencias y perspectivas de las personas sobre los programas, fen&#x00F3;menos complejos que implican el contexto social, la cultura y la educaci&#x00F3;n (<xref ref-type="bibr" rid="CIT054">Creswell &#x0026; Poth, 2018</xref>; <xref ref-type="bibr" rid="CIT108">Korstjens &#x0026; Moser, 2017</xref>).</p>
<p>Es preciso se&#x00F1;alar que en las investigaciones cualitativas no se pretende buscar la representatividad, ni la extrapolaci&#x00F3;n y/o generalizaci&#x00F3;n de los resultados (<xref ref-type="bibr" rid="CIT045">Carpenter &#x0026; Suto, 2008</xref>; Creswell, 2012). Esto conlleva que los criterios de calidad aplicados para estudios cuantitativos y la aplicaci&#x00F3;n de criterios como los aplicados para estudios observacionales mediante la recomendaci&#x00F3;n STROBE o en ensayos cl&#x00ED;nicos con las recomendaciones CONSORT no puedan ser aplicados (<ext-link ext-link-type="uri" xlink:href="https://www.equator-network.org/">https://www.equator-network.org/</ext-link>).</p>
<p>Para satisfacer a los criterios de calidad de la investigaci&#x00F3;n cualitativa se ha seguido las recomendaciones <italic>The Consolidated criterie for reporting qualitative research</italic>-COREQ (<xref ref-type="bibr" rid="CIT195">Tong, Sainsbury, &#x0026; Craig, 2007</xref>) y <italic>the Standards for reporting qualitative research</italic>-SRQR (<xref ref-type="bibr" rid="CIT155">O&#x2019;Brien, Harris, Beckman, Reed, &#x0026; Cook, 2014</xref>) en los tres estudios. Adem&#x00E1;s se aplicaron los criterios de <xref ref-type="bibr" rid="CIT123">Lincoln &#x0026; Guba (1985)</xref> para establecer la credibilidad, la transferibilidad, la fiabilidad y la confirmabilidad (<xref ref-type="bibr" rid="CIT183">Shenton, 2004</xref>). Dentro de cada uno de los criterios, se aplicaron diferentes estrategias y/o t&#x00E9;cnicas de control de calidad.</p>
<p>Para la credibilidad (<italic>credibility</italic>); en el estudio 1 (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) se utiliz&#x00F3; la validaci&#x00F3;n de los participantes y triangulaci&#x00F3;n de los instrumentos; en el estudio 2 (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) se utiliz&#x00F3; &#x00FA;nicamente la triangulaci&#x00F3;n; y en el estudio 3 (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) se utiliz&#x00F3; la triangulaci&#x00F3;n de los instrumentos y la validaci&#x00F3;n de los participantes.</p>
<p>Para la transferibilidad (<italic>transferability</italic>); en los 3 estudios (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>; <xref ref-type="bibr" rid="CIT133">2020</xref>; <xref ref-type="bibr" rid="CIT134">2021</xref>) se utiliz&#x00F3; la descripci&#x00F3;n en profundidad.</p>
<p>Para la fiabilidad (<italic>dependability</italic>); en los 3 estudios (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>; <xref ref-type="bibr" rid="CIT133">2020</xref>; <xref ref-type="bibr" rid="CIT134">2021</xref>) se utiliz&#x00F3; una auditor&#x00ED;a externa.</p>
<p>Para la confirmabilidad (<italic>confirmability</italic>); en todos los estudios (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>; <xref ref-type="bibr" rid="CIT133">2020</xref>; <xref ref-type="bibr" rid="CIT134">2021</xref>) se utilizaron la auditor&#x00ED;a externa, triangulaci&#x00F3;n y reflexividad.</p>
<p>A continuaci&#x00F3;n, se describen cada una de las t&#x00E9;cnicas utilizadas.</p>
<p><target target-type="page" id="pges_95"/>La triangulaci&#x00F3;n del investigador, consisti&#x00F3; en el uso de m&#x00FA;ltiples fuentes de datos en la investigaci&#x00F3;n para entender de forma m&#x00E1;s precisa el fen&#x00F3;meno estudiado (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>).</p>
<p>La triangulaci&#x00F3;n de los instrumentos de recogida de datos signific&#x00F3; utilizar diferentes herramientas de recogida de datos (entrevistas, formularios datos sociodemogr&#x00E1;ficos), junto a la obtenci&#x00F3;n de datos cualitativos junto con datos cuantitativos, como pueden ser la edad de los participantes, la nacionalidad, el n&#x00FA;mero de hijos, sus ingresos, el tipo de trabajo que tienen o sus a&#x00F1;os de experiencias (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>).</p>
<p>La validaci&#x00F3;n de los participantes o <italic>member checking</italic> consisti&#x00F3; en comprobar con los participantes los datos obtenidos durante las entrevistas o en los grupos focales. De este modo se daba la oportunidad a los participantes a ampliar la informaci&#x00F3;n recogida previamente (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>).</p>
<p>La descripci&#x00F3;n en profundidad se realiz&#x00F3; para asegurar la transferibilidad, y consisti&#x00F3; en la descripci&#x00F3;n detallada del protocolo de investigaci&#x00F3;n, el contexto, los participantes de los diferentes estudios, y la descripci&#x00F3;n de la recogida de datos y an&#x00E1;lisis de los mismo (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>).</p>
<p>El auditor/investigador externo sirvi&#x00F3; para garantizar la confiabilidad. Este auditor externo revis&#x00F3; el protocolo de investigaci&#x00F3;n, centr&#x00E1;ndose en el desarrollo de materiales y m&#x00E9;todos. Las auditor&#x00ED;as externas implican que un investigador que no participa en el proceso de investigaci&#x00F3;n examine tanto el proceso como el producto del estudio de investigaci&#x00F3;n. El prop&#x00F3;sito de esa auditoria era evaluar la exactitud y valorar si los resultados, las interpretaciones y las conclusiones se apoyan en los datos obtenidos (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>). En el primer (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) y tercer estudio (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) se aplic&#x00F3; una auditoria al principio y al final de los estudios. Mientras, que en el segundo estudio (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) se realizaron cuatro pruebas de auditor&#x00ED;a externa, antes de comenzar el estudio (antes de febrero de 2017), dos veces durante el estudio (de febrero de 2017 a junio de 2017; en marzo y mayo de 2017), y una vez despu&#x00E9;s de la finalizaci&#x00F3;n del estudio (despu&#x00E9;s de junio de 2017).</p>
<p>El proceso de reflexividad de los investigadores consisti&#x00F3; en registrar la perspectiva de los investigadores, posiciones, valores y creencias (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>). En investigaci&#x00F3;n cualitativa es relevante debido a que las ideas preconcebidas, creencias o valores pueden influir en la interpretaci&#x00F3;n o direccionalidad de la recogida de datos o su an&#x00E1;lisis (<xref ref-type="bibr" rid="CIT109">Korstjens &#x0026; Moser, 2018</xref>). Adem&#x00E1;s, las recomendaciones COREQ (<xref ref-type="bibr" rid="CIT195">Tong et al., 2007</xref>) y SRQR (<xref ref-type="bibr" rid="CIT155">O&#x2019;Brien et al., 2014</xref>) consideran la inclusi&#x00F3;n del proceso reflexivo como un indicador necesario dentro de los apartados de los estudios cualitativos en ciencias de la salud.</p>
<p><target target-type="page" id="pges_96"/>Para la presente tesis, se obtuvo la aprobaci&#x00F3;n del Comit&#x00E9; &#x00C9;tico de Investigaci&#x00F3;n Cl&#x00ED;nica de la Universidad Rey Juan Carlos (c&#x00F3;digo de identificaci&#x00F3;n del proyecto: 3001201702417). El estudio se realiz&#x00F3; de acuerdo con los principios articulados en la Declaraci&#x00F3;n de Helsinki de la AMM (Principios &#x00E9;ticos para la investigaci&#x00F3;n m&#x00E9;dica en seres humanos). Adem&#x00E1;s, se sigui&#x00F3; la Ley de Protecci&#x00F3;n de Datos de Car&#x00E1;cter Personal y la Ley de Investigaci&#x00F3;n Biom&#x00E9;dica.

<title><italic>Fortalezas:</italic></title>
<p>La fortaleza de esos tres estudios (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>; <xref ref-type="bibr" rid="CIT133">2020</xref>; <xref ref-type="bibr" rid="CIT134">2021</xref>) es que en conjunto, los tres estudios dan una perspectiva profunda de las dificultades que encuentran los ni&#x00F1;os y j&#x00F3;venes inmigrantes para practicar AF desde diferentes perspectivas.</p>
<sec id="c4-s3-s1-s1">
<title>Estudio 1.</title>
<p>La fortaleza del primer estudio (<xref ref-type="bibr" rid="CIT132">Marconnot et al., 2019</xref>) es que presenta la perspectiva de los padres, profesores de EF y responsables religiosos, es decir de la comunidad en la que se desarrollan los ni&#x00F1;os y j&#x00F3;venes inmigrantes. Permite comprender desde la visi&#x00F3;n en primera persona de los actores sociales principales las limitaciones y barreras a la pr&#x00E1;ctica de AF de los ni&#x00F1;os y j&#x00F3;venes inmigrantes.</p>

<title>Estudio 2.</title>
<p>La fortaleza del segundo estudio (<xref ref-type="bibr" rid="CIT133">Marconnot et al., 2020</xref>) es que se focaliza sobre la perspectiva de los padres y madres de los ni&#x00F1;os y j&#x00F3;venes inmigrantes. Eso permite a los profesionales del &#x00E1;rea de la educaci&#x00F3;n y EF (profesores de EF, monitores y entrenadores deportivos o responsables pol&#x00ED;ticos) comprender la experiencia de los padres y madres, sus dificultades y necesidades en promover la AF en sus hijos.</p>

<title>Estudio 3.</title>
<p>La fortaleza del tercer estudio (<xref ref-type="bibr" rid="CIT134">Marconnot et al., 2021</xref>) es que se focaliza sobre el punto de vista de los profesores de EF y sobre aquellos factores que pueden condicionar la pr&#x00E1;ctica de la AF en los ni&#x00F1;os y adolescentes inmigrantes.

<p>S&#x00F3;lo se incluyeron participantes de un &#x00FA;nico contexto religioso (es decir, el catolicismo). Ser&#x00ED;a necesario desarrollar futuros estudios con inmigrantes de otras religiones.</p>

<title>Estudio 2.</title>
<p>En primer lugar, no se pudo realizar una agrupaci&#x00F3;n homog&#x00E9;nea de los padres/madres inmigrantes por zonas geogr&#x00E1;ficas bien definidas. No se pudo focalizar el estudio en una poblaci&#x00F3;n espec&#x00ED;fica y originaria de Latino Am&#x00E9;rica exclusivamente. Ser&#x00ED;a necesario desarrollar futuros estudios con inmigrantes de otras zonas geogr&#x00E1;ficas. Adem&#x00E1;s, no se pudo identificar si los ni&#x00F1;os/as hab&#x00ED;an nacido en Espa&#x00F1;a o hab&#x00ED;an sido trasladados desde su pa&#x00ED;s de origen. Pero esa limitaci&#x00F3;n pod&#x00ED;a estar controlada, ya que no se investigaba la perspectiva de los hijos, sino la de los padres y madres. Por &#x00FA;ltimo, este estudio cualitativo de caso se limita en el tiempo y en el lugar y en un contexto determinado. Ser&#x00ED;a necesario otros estudios que incluyesen otros contextos.</p>

<title>Estudio 3.</title>
<p>Los profesores/as incluidos en el estudio no formaban parte de las aulas de enlace, aulas destinadas al apoyo y la adaptaci&#x00F3;n de los ni&#x00F1;os y adolescentes inmigrantes que se incorporan a la escuela. Eso podr&#x00ED;a influir en los resultados. <target target-type="page" id="pges_98"/>Adem&#x00E1;s, no se pregunt&#x00F3; a los profesores sobre el proceso de ense&#x00F1;anza de la EF a los ni&#x00F1;os y adolescentes, lo que podr&#x00ED;a revelar diferencias en la realizaci&#x00F3;n de la AF. Ser&#x00ED;a necesario incorporar a profesores de otras &#x00E1;reas de ense&#x00F1;anza y a profesores de las aulas de enlace. Otro aspecto clave a incluir en pr&#x00F3;ximos estudios, ser&#x00ED;a describir los procesos de ense&#x00F1;anza por los profesores de EF para identificar (si las hay) entre el alumnado espa&#x00F1;ol y el alumnado inmigrante.</p>

<p>Las conclusiones de la presente tesis responden a las preguntas de investigaci&#x00F3;n propuestas.</p>
<p><bold>Estudio 1:</bold> &#x00BF;Qu&#x00E9; barreras encuentran los padres, profesores, directores de escuela y lideres de comunidades a la hora de promover la AF entre los ni&#x00F1;os reci&#x00E9;n inmigrados que se enfrentan a un nuevo contexto cultural?</p>
<list list-type="bullet">
<list-item><p>Se identific&#x00F3; la carga acad&#x00E9;mica (deberes) como un factor limitante importante a la hora de promover la AF en sus hijos.</p></list-item>
<list-item><p>Existen dificultades de conciliaci&#x00F3;n familiar entre carga laboral y familiar que afecta a la AF. Los padres y madres trabajan muchas horas fuera de casa y en horarios a veces incompatibles con el horario escolar.</p></list-item>
<list-item><p>Los problemas econ&#x00F3;micos pueden limitar la AF de sus hijos. Muchos de ellos se encuentran en situaciones econ&#x00F3;micas que no les permiten hacer frente a los gastos que conllevan la pr&#x00E1;ctica de AF extraescolar.</p></list-item>
<list-item><p>Los padres y madres describen como su entorno afecta a promover AF: falta de infraestructuras deportivas accesibles, parques poco seguros, problemas de transportes. Los barrios de ciudades no est&#x00E1;n organizado y estructurados de forma correcta para facilitar a las familias una pr&#x00E1;ctica adecuada de AF.</p></list-item>
</list>
<p><bold>Estudio 2:</bold> &#x00BF;Qu&#x00E9; significado y que perspectiva tienen las familias de ni&#x00F1;os/as inmigrantes sobre la pr&#x00E1;ctica de la AF?</p>
<list list-type="bullet">
<list-item><p>Los padres y madres describen el nivel socioecon&#x00F3;mico como una barrera para promover la AF en sus hijos. Apuntar a sus hijos a actividades extraescolares tiene un coste (inscripci&#x00F3;n, material deportivo) que muchas familias no pueden hacer frente.</p></list-item>
<list-item><p>Aparece la limitaci&#x00F3;n de tiempo y barreras en la conciliaci&#x00F3;n familiar. Las familias tienen horarios de trabajo incompatible con el horario escolar y la organizaci&#x00F3;n familiar entre los hermanos y las tareas dom&#x00E9;sticas.</p></list-item>
<list-item><p>Describen como los barrios donde residen influye sobre la pr&#x00E1;ctica de AF. Los barrios presentan problemas de inseguridad. Las infraestructuras deportivas o de ocio al aire libre (parques) no siempre se encuentran cerca de sus domicilios, lo que a&#x00F1;ade problemas de transporte y de accesibilidad.</p></list-item>
</list>
<p><target target-type="page" id="pges_100"/><bold>Estudio 3:</bold> &#x00BF;Cu&#x00E1;l es la perspectiva de los profesores/as que imparten EF en ni&#x00F1;os/as y j&#x00F3;venes inmigrantes sobre la AF en el medio escolar?</p>
<list list-type="bullet">
<list-item><p>Los profesores describen que la pr&#x00E1;ctica habitual de AF y la utilizaci&#x00F3;n de la EF son unos medios de integraci&#x00F3;n social importante en la vida de los ni&#x00F1;os y j&#x00F3;venes inmigrantes. La AF ayuda en la lucha contra las discriminaciones y la exclusi&#x00F3;n social que pueden parecer los alumnos extranjeros cuando llegan en un nuevo pa&#x00ED;s.</p></list-item>
<list-item><p>No existe una formaci&#x00F3;n adecuada en el profesorado para conocer y manejar alumnos/as con culturas y creencias diferente.</p></list-item>
<list-item><p>Los profesores identifican el nivel educativo de los padres como una limitaci&#x00F3;n a la pr&#x00E1;ctica de AF de sus hijos. Identifican falta de conocimiento respecto a los beneficios de la AF en la salud y el desarrollo de los ni&#x00F1;os.</p></list-item>
<list-item><p>Los problemas econ&#x00F3;micos que padecen las familias podr&#x00ED;an explicar la participaci&#x00F3;n en los programas deportivos (IPAFD) de los colegios e institutos por los alumnos/as extranjeros, debido a su bajo coste.</p></list-item>
<list-item><p>Existen dificultades para manejar componentes culturales y religiosos. Los profesores describen como las creencias religiosas pueden dificultar la pr&#x00E1;ctica de AF de las ni&#x00F1;as sobre todo en la poblaci&#x00F3;n Magreb&#x00ED;.</p></list-item>
<list-item><p>A pesar de que los profesores de EF muestran una perspectiva cr&#x00ED;tica a la promoci&#x00F3;n de AF en alumnos/as inmigrantes, su discurso es positivo y de aceptaci&#x00F3;n. Existiendo una mayor tendencia a la positividad de su perspectiva ante el fen&#x00F3;meno de la pr&#x00E1;ctica de AF en alumnos/as de origen extranjero.</p></list-item>
