Exploring the mediating role of promoting school physical activity on the relationship between low socioeconomic status and academic achievement and school climate: evidence from 4,990 Chilean schools.

There is evidence that promoting school physical activity (PSPA) benefits children and adolescents, but little is understood about how this promotion may relate to academic achievement and school climate across varying levels of socioeconomic status (SES). Hence, the study aimed to address this knowledge gap by examining two main objectives: (1) determining the association between PSPA and academic achievement and school climate according to schools' SES and (2) exploring the potential mediating role of PSPA in the relationship between schools' SES and academic achievement and school climate. This cross-sectional study at the school level focused on 4,990 schools (including public, subsidized, and private schools) that participated in the National Educational Study 2018 (Chile), which was applied to primary schoolchildren (4th grade, aged 8-10 years). Schools were divided into non-PSPA (n = 4,280) and PSPA (n = 710) during the year 2018. Changes in academic achievement from 2017 to 2018 and school climate were considered. PSPA was associated with improvements in maths (low-SES OR: 1.80, p < 0.001) and reading (middle-SES OR: 1.45, p = 0.029; low-SES OR: 1.47, p < 0.001). The indirect effect (IE) showed that PSPA partially mediated the relationship between SES and academic achievement in reading (IE = 1.017; SE = 0.12; 95%CI, -1.27, -0.77), maths (IE = -1.019; SE = 0.12; 95%CI, -1.25, -0.78), and school climate (IE = -0.46; SE = 0.52; 95%CI, -0.56, -0.35). In conclusion, PSPA was linked to positive changes in academic achievement, especially among low SES, and PSPA presented a potential mediating role in the relationship between SES of schools and academic achievement and school climate.

Concepciones y Prácticas Evaluativas en la Formación Inicial del Profesorado en Educación Física

La evaluación ha dejado de ser una instancia que sólo certifica el logro alcanzado a través de una calificación, sino actualmente se entiende como un elemento fundamental para favorecer los procesos de enseñanza-aprendizaje. El objetivo del presente estudio fue "Conocer las concepciones y prácticas evaluativas del alumnado y profesorado de la FIPEF (Formación Inicial del Profesorado en Educación Física) de dos campus universitarios de la zona sur austral de Chile". Para ello, se contó con una muestra de 219 alumnos y alumnas (edad M = 21.6 y dt. = 2.8) de dos campus universitarios que cursaban Formación Inicial del Profesorado en Educación Física (FIPEF) y 21 profesores y profesoras (edad M = 50.3 y dt. = 13.2). Se aplicó el "Cuestionario para el estudio del sistema de evaluación en la formación inicial del profesorado de educación física" de forma virtual, sometiendo los resultados a pruebas estadísticas como la media, desviación típica y pruebas inferenciales. Los principales resultados dejan ver la presencia de metodologías e instrumentos tradicionales de evaluación, así como, una apreciación diferenciada entre alumnado vs. profesorado. Sin embargo, se puede constatar la presencia de intencionalidad formativa en las acciones implementadas por el profesorado.

The evaluation has ceased to be a mere instance that only certifies the achievement through a grade; rather, it is currently understood as a fundamental element to promote teaching and learning processes. The objective of the present study was to "Understand the conceptions and evaluative practices of students and faculty in the FIPEF (Initial Teacher Education in Physical Education) of two university campuses in the southernmost region of Chile." For this purpose, a sample of 219 students (age M = 21.6 and SD = 2.8) from two university campuses undergoing Initial Teacher Education in Physical Education (FIPEF) and 21 teachers (age M = 50.3 and SD = 13.2) was used. The "Questionnaire for the study of the evaluation system in the initial teacher education of physical education" was administered in a virtual manner, subjecting the results to statistical tests such as mean, standard deviation, and inferential tests. The main results reveal the presence of traditional evaluation methodologies and instruments, as well as a differentiated perception between students and faculty. However, there is evidence of formative intent in the actions implemented by the faculty.

A avaliação deixou de ser apenas uma instância que certifica a conquista por meio de uma nota; atualmente, é compreendida como um elemento fundamental para promover os processos de ensino e aprendizagem. O objetivo do presente estudo foi "Compreender as concepções e práticas avaliativas dos estudantes e professores da FIPEF (Formação Inicial de Professores de Educação Física) de dois campi universitários na região sul-austral do Chile." Para isso, contamos com uma amostra de 219 alunos (idade M = 21,6 e dp. = 2,8) de dois campi universitários que cursavam a Formação Inicial de Professores de Educação Física (FIPEF) e 21 professores (idade M = 50,3 e dp. = 13,2). Foi aplicado o "Questionário para o estudo do sistema de avaliação na formação inicial de professores de educação física" de forma virtual, sujeitando os resultados a testes estatísticos como média, desvio padrão e testes inferenciais. Os principais resultados revelam a presença de metodologias e instrumentos tradicionais de avaliação, bem como uma percepção diferenciada entre alunos e professores. No entanto, há evidências de intencionalidade formativa nas ações implementadas pelos professores.

After-school sports programmes and social inclusion processes in culturally diverse contexts: Results of an international multicase study.

This research aimed to understand the role of after-school sports programs in social inclusion processes in culturally diverse contexts through a multicase study within two locations. The first location was in Spain where immigrant and Spanish students were enrolled, and the other was in Chile with Mapuche-Huilliche students, immigrant and Chilean students. The implemented programs at both sites were similar in their educational focus on socio-educational values, and teaching models (hybridization of teaching games for understanding and cooperative learning) that enhance social inclusion. Using individual and group interviews with teachers, sports coordinators, parents, and students, a qualitative approach was used to identify the factors that facilitate or hinder the social inclusion processes. In addition, the researchers used qualitative observations of the programs over six months using "notes logbook" to record their impressions during the observation process. Results indicated that the implemented sports programs successfully facilitated social inclusion processes, enabling the development of interpersonal skills and relationships between students from different cultural backgrounds. The previous training and experiences of teachers in culturally diverse contexts, and incorporation of traditional sporting games from all cultures, seems to be an important facilitator factor for the inclusion potential of the implemented programs.

Negative Physical Self-Concept Is Associated to Low Cardiorespiratory Fitness, Negative Lifestyle and Poor Mental Health in Chilean Schoolchildren.

Background: Evidence suggests that physical self-concept (PSC) is linked to well-being in children and adolescents. Objective: The objective was to investigate the association of PSC with mental health (i.e., depression and body image), physical status (i.e., fitness and weight status) and lifestyle (physical activity (PA) patterns and nutritional level) in Chilean schoolchildren. Methods: A total of 617 schoolchildren (n = 271 girls and n = 346 boys) aged 10−14 years participated in this study. Self-concept, depression and body image dissatisfaction were determined by questionnaires. Physical fitness, PA, screen time (ST), Mediterranean diet (MD) adherence and anthropometric parameters were also included. Results: Poor PSC was linked to bad cardiorespiratory fitness (CRF) (<42 VO2max) (OR 1.64; 95%CI 1.12−2.34; p = 0.01), severe body image dissatisfaction (OR 2.51, 95%CI 0.99−6.35; p = 0.05), ST of more than two hours a day (OR 2.1; 95%CI 1.41−3.12; p < 0.001), PA after school of no more than two hours per week (OR 1.52; 95%CI 1.08−2.13; p = 0.015) and depression (OR 1.80; 95%CI 1.1−2.92; p = 0.017). High nutritional level showed an association with general PSC and general self-concept (p < 0.05). Absence of body image dissatisfaction was related to general self-concept (p < 0.01) and physical condition dimensions (p < 0.05). Conclusions: PSC is associated with CRF, PA after school, ST and nutritional level. According to mental health variables, poor PSC is related to depression in Chilean schoolchildren. Therefore, promoting a healthy lifestyle among children should be a target of community- and school-based interventions to promote PSC.

Psychological well-being related to screen time, physical activity after school, and weight status in Chilean schoolchildren.

INTRODUCTION: Background: the relationship between physical activity (PA) patterns and mental health in children is receiving considerable attention. Aims: the aim of this study was to compare psychological well-being in groups of schoolchildren according to PA patterns and weight status, and to determinate the association between psychological well-being and both screen time and PA after school. Material and methods: in a cross-sectional sample of girls (n = 272, aged 11.93 ± 0.94 years) and boys (n = 333, aged 12.09 ± 1.00 years), we assessed body mass index (BMI), waist circumference and body fat. Self-esteem, body image dissatisfaction, depression, screen time, and after-school PA were also included. Results: according to PA patterns, there were significant differences between good PA and bad PA groups in self-esteem (p = 0.013) and depression (p = 0.035). BMI was associated with depression (ß: 0.36; 95% CI: 0.19, 0.53; p < 0.001). Screen time was positively associated with depression (ß: 0.88; 95% CI: 0.32, 1.44; p = 0.002) and inversely associated with self-esteem (ß: -1.12; 95% CI: -1.79, -0.45; p < 0.001). Finally, after-school PA had an inverse association with depression levels (ß: -0.55; 95% CI: 0.10, 1.00; p = 0.016). Conclusion: psychological well-being was associated with screen time, after-school PA and weight status in schoolchildren.

INTRODUCCIÓN: Antecedentes: la relación entre los patrones de actividad física (AF) y la salud mental en los niños está recibiendo una atención considerable. Objetivos: el objetivo de este estudio fue comparar el bienestar psicológico en grupos de escolares de acuerdo con los patrones de AF y el estado de peso, y determinar la asociación entre el bienestar psicológico y tanto el tiempo frente a la pantalla como la AF después de la escuela. Material y métodos: en una muestra transversal de niñas (n = 272, de 11,93 ± 0,94 años) y niños (n = 333, de 12,09 ± 1,00 años), evaluamos el índice de masa corporal (IMC), la circunferencia de la cintura y la grasa corporal. También se incluyeron la autoestima, la insatisfacción con la imagen corporal, la depresión, el tiempo frente a la pantalla y la AF después de la escuela. Resultados: de acuerdo con los patrones de AF, hubo diferencias significativas entre los buenos niveles de AF y la malos niveles de AF en la autoestima (p = 0,013) y la depresión (p = 0,035). El IMC de los participantes se asoció con depresión (ß: 0,36; IC 95%: 0,19 a 0,53; p < 0,001). El tiempo de pantalla se asoció positivamente con la depresión (ß: 0,88; IC 95%: 0,32 a 1,44; p = 0,002) e inversamente con la autoestima (ß: -1,12; IC 95%: -1,79 a -0,45; p < 0,001). Finalmente, la AF después de la escuela tuvo una asociación inversa con los niveles de depresión (ß: -0,55; IC 95%: 0,10 a 1,00; p = 0.016). Conclusión: el bienestar psicológico se asoció con el tiempo frente a la pantalla, la PA después de la escuela y el estado de peso de los escolares.

Relación entre salud y deporte escolar desde una perspectiva intercultural, un estudio multicaso / Correlation between health and school sports from an intercultural perspective: multiple case study

Resumen Introducción. La salud y el deporte configuran prácticas, creencias y relaciones culturales particulares en cada contexto. Objetivo. Analizar las creencias de estudiantes inmigrantes y mapuche-huilliche sobre la relación entre deporte escolar y salud. Materiales y métodos. Se desarrolló un estudio multicaso cualitativo con enfoque etnográfico. Participaron 71 sujetos subdivididos en dos grupos: uno constituido por estudiantes inmigrantes que participaban de un programa de deporte escolar con principios comprensivos de enseñanza en España (n=47) y otro compuesto por alumnos de la etnia Mapuche-Huilliche que participaban de un programa análogo en Chile (n=24). Para la recolección de datos se aplican tres entrevistas colectivas a cada grupo. Resultados. Ambos colectivos perciben una asociación positiva entre la participación en deporte escolar y el desarrollo de la salud en diferentes dimensiones. Existen diferencias respecto a la interpretación cultural que ambos grupos otorgan al concepto salud y sus posibles relaciones con el deporte escolar. Sin embargo, en ambos contextos existen situaciones en que se considera de forma parcial la cultura de los estudiantes para trabajar sobre estos temas. Conclusiones. Estudiantes inmigrantes y mapuche-huilliche establecen creencias positivas sobre la relación entre deporte escolar y desarrollo de salud en sus diferentes manifestaciones.

Abstract Introduction: Health and sports shape particular practices, beliefs and cultural relationships in different contexts. Objective: To analyze the beliefs of immigrant and Huilliche-Mapuche students about the correlation between school sports and health. Materials and methods: A qualitative multiple-case study was developed based on an ethnographic approach. Participants included 71 subjects subdivided into two groups: one made up of immigrant students who participated in a school sports program with comprehensive teaching principles in Spain (n=47) and another made up of Huilliche-Mapuche students who participated in a similar program in Chile (n=24). Three group interviews were applied to each group for data collection. Results: Both groups perceived a positive association between participation in school sports and the development of health in different dimensions. There are differences regarding the cultural interpretation that both groups give to the concept of health and its possible correlation with school sports. However, both contexts present situations in which the culture of students is partially considered to work on these issues. Conclusions: Migrant and Huilliche-Mapuche students reported positive beliefs about the correlation between school sports and health development in its different manifestations.

Prescripcion del ejercicio fisico para la salud, influencia del entrenamiento de la fuerza intermitente y en la composición corporal de universitarios sedentarios con ascendencia étnica diversa / Prescription of physical exercise for health impact of training in strength indicator body composition of university sedentary with different ethnic ancestry

El objetivo del estudio es determinar si el entrenamiento de fuerza de tipo intermitente modifica la composición corporal principalmente el porcentaje de grasa y masa muscular de jóvenes sedentarios universitarios. Estudio cuasi experimental con pre prueba y pos-prueba en una muestra de 8 sujetos sin grupo control, seleccionados de manera intencionada. Se realizó medición antropométrica al comienzo y al finalizar el programa de entrenamiento. Se concluyó que un programa de entrenamiento de 2 meses de duración con 3 sesiones semanales en días alternos, provoca disminución significativa (p<0,05) en la masa grasa y un aumento significativo (p<0,05) en la masa muscular, por lo cual se comprueba que el entrenamiento intermitente con sobrecarga, provoca cambios significativos en la fuerza máxima, y composición corporal en personas sedentarias.

The aim of the study is to determine whether strength training intermittent type body composition changes mainly fat percentage and muscle mass of young university sedentary. Quasi experimental study with pre-test and post-test on a sample of 8 subjects with no control group, selected intentionally. Anthropometric at the beginning and end of the training program was conducted measurement. It was concluded that a training program 2 months with 3 sessions per week on alternate days caused significant decrease (p <0.05) in fat mass and a significant increase (p <0.05) in muscle mass, which is proven by the intermittent resistance training causes significant changes in maximal strength, and body composition in sedentary people.
