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.

A Look at the Interconnection of Dimensions of Knowledge in Physical Education Teacher Training in Chile.

The massive fragmentation of knowledge that exists in the current field of physical education enables us to research pedagogical and disciplinary aspects in the educational processes of teachers in training, as this has significant implications for future educational practices. This study proposes to assess the dimensions of knowledge (conceptual, procedural and attitudinal) that stem from the learnings that emerge in physical education teacher training in terms of the disciplinary standards proposed by the Chilean Education Ministry for the Preservice Teacher Education. The study methodology was descriptive and inferential, and the cohort was cross-sectional. A total of 750 fourth- and fifth-year students in training from 13 Chilean universities participated. Of these, 619 subjects were considered: 54.6% (338) men and 45.4% (281) women between the ages of 21 and 25. The questionnaire used for data collection was the "Questionnaire on Conceptual, Procedural and Attitudinal Learning in Preservice Teacher Education in Physical Education" (CACPA-FIDEF), prepared as part of Fondecyt project No. 11190537. The main results indicate that there are no statistically significant differences in the three dimensions in terms of students' sex and type of schooling, with p values > 0.05. In conclusion, the study observed a weak conceptual management of the discipline in future teachers, revealing once again the need to seek out didactic alternatives that enable teachers in training to understand the importance of the conceptual dimension in their learning and teaching processes.

Pattern analysis of a complete Achilles tendon rupture suffered during high jump preparation in an official national-level athletic competition.

Elite athletes are subject to injuries like the Achilles tendon rupture. This injury requires a long recovery process, with no guarantee of returning to the pre-injury level. When a rupture happens during natural life, movement analysis can provide useful insights concerning patterns of rupture to understand and prevent Achilles tendon injuries. Here we determined the pattern of rupture of an Achilles tendon (AT) in an elite high-jumper athlete who ruptured an AT during the straight line running phase in preparation for a high-jump attempt. This study is a novel case report regarding a national-level elite athlete. The main outcomes were kinematics parameters obtained from video analysis. The pattern of the rupture was determined by pixel intensity and outlier analysis. The rupture occurred at 44% of the single stance. The injured leg showed a higher ankle dorsal flexion and knee-ankle ratio, and a lower knee flexion compared to contralateral leg. An eccentric pattern of rupture occurred during the transition from the mid to terminal stance phases of running. The lower knee flexion and the increased ankle dorsal flexion during the stance suggest a loss of knee-ankle coordination. This might have favoured a major elongation of Achilles tendon causing the rupture.

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.

Comparison of body composition and physical performance between college and professional basketball players / Comparación de la composición corporal y rendimiento físico entre jugadores de baloncesto universitario y profesional

Introduction: The body composition, anthropometrics and physical performance of basketball players are fundamental for their practice of the sport. The purpose of this study was to evaluate and compare body composition and physical performance among college and professional basketball players. Method: The sample consisted of 2 groups of male basketball players (n=17) (age: 23.61±3.45): Group 1 college players (n=9; age: 22.48±3.79 years), and Group 2 professional players (n=8; age: 24.88±2.69 years). Weight, height, fat mass and muscle mass were measured. Physical performance was measured in throwing the ball (m/s), gripping strength (Kg), speed over 20 metres, jumping and reactive strength. The mean height of the college basketball players was 179.44±7.97 cm, weight 83.61±14.64 kg, body mass index (BMI) 25.94±3.95 kg/m2, % body fat mass 16.64±7.07, % Muscle mass 47.59±4.01; the mean height of the professional players was 181.50±8.42 cm, weight 89.73±25.56 kg, BMI 26.94±5.87 kg/m2, % body fat mass 19.26±8.20, % Muscle mass 46.26±4.55. Results: There were no significant differences in the % of body fat and muscle mass, similar results to those found in handgrip strength, ball-throwing speed and speed in 20 meters with and without the ball (p >0.05). For physical performance only the Q index and the floor contact time (DJ-t) in drop jumps presented statistical differences (p <0.05), with better results achieved by the college players. Conclusion: College and professional basketball players do not show significant differences in body composition and variables associated with physical performance, especially the vertical jump capacity that is lower in both groups compared to what is reported in the scientific literature

Introducción: La composición corporal, antropométrica y el rendimiento físico de los jugadores de baloncesto, son fundamentales en el desempeño deportivo. El propósito de este estudio fue evaluar y comparar la composición corporal y el rendimiento físico entre jugadores de baloncesto universitario y profesional. Método: La muestra estuvo constituida por 2 grupos de jugadores de baloncesto varones (n=17) (edad: 23,61±3,45), el grupo 1 por universitarios (n=9; Edad: 22,48± 3,79 años) y el grupo 2 por profesionales (n=8; Edad: 24,88± 2,69 años). Se evaluó peso, talla, masa grasa y muscular. El rendimiento físico se midió a través del lanzamiento de balón (m/s), fuerza prensil (Kg), velocidad en 20 metros, capacidad de salto y fuerza reactiva. El grupo de jugadores de baloncesto universitario presentó una talla promedio de 179,44 ± 7,97 cm, peso corporal 83,61 ± 14,64 kg, índice de masa corporal (IMC) 25,94 ± 3,95 Kg/m2, % masa grasa 16,64±7,07, % masa muscular 47,59±4,01, en cambio los profesionales presentaron una talla de 181,50 ± 8,42 cm, peso corporal 89,73 ± 25,56 kg, IMC 26,94 ± 5,87 Kg/m2, % masa grasa 19,26 ± 8,20 y % masa muscular 46,26 ± 4,55. Resultados: En la comparación del % de grasa corporal y masa muscular no existieron diferencias significativas, resultados similares a los encontrados en fuerza prensil, velocidad de lanzamiento del balón y velocidad en 20 metros con y sin el balón (p >0,05). En relación al rendimiento físico solo el índice Q y el tiempo de contacto en Drop Jump (DJ-t) presentaron diferencias estadísticas (p <0,05), con mejores resultados en el grupo universitario. Conclusiones: Los jugadores de baloncesto universitario y profesional no muestran diferencias significativas en la composición corporal y las variables asociadas con el rendimiento físico sobretodo la capacidad de salto vertical que es menor en ambos grupos comparado con lo reportado en la literatura científica

Intersession and Intrasession Reliability and Validity of the My Jump App for Measuring Different Jump Actions in Trained Male and Female Athletes.

Gallardo-Fuentes, F, Gallardo-Fuentes, J, Ramírez-Campillo, R, Balsalobre-Fernández, C, Martínez, C, Caniuqueo, A, Cañas, R, Banzer, W, Loturco, I, Nakamura, FY, and Izquierdo, M. Intersession and intrasession reliability and validity of the My Jump app for measuring different jump actions in trained male and female athletes. J Strength Cond Res 30(7): 2049-2056, 2016-The purpose of this study was to analyze the concurrent validity and reliability of the iPhone app named My Jump for measuring jump height in 40-cm drop jumps (DJs), countermovement jumps (CMJs), and squat jumps (SJs). To do this, 21 male and female athletes (age, 22.1 ± 3.6 years) completed 5 maximal DJs, CMJs, and SJs on 2 separate days, which were evaluated using a contact platform and the app My Jump, developed to calculate jump height from flight time using the high-speed video recording facility on the iPhone. A total of 630 jumps were compared using the intraclass correlation coefficient (ICC), Bland-Altman plots, Pearson's product moment correlation coefficient (r), Cronbach's alpha (α), and coefficient of variation (CV). There was almost perfect agreement between the measurement instruments for all jump height values (ICC = 0.97-0.99), with no differences between the instruments (p > 0.05; mean difference of 0.2 cm). Almost perfect correlation was observed between the measurement instruments for SJs, CMJs, and DJs (r = 0.96-0.99). My Jump showed very good within-subject reliability (α = 0.94-0.99; CV = 3.8-7.6) and interday reliability (r = 0.86-0.95) for SJs, CMJs, and DJs in all subjects. Therefore, the iPhone app named My Jump provides reliable intersession and intrasession data, as well as valid measurements for maximal jump height during fast (i.e., DJs) and slow (i.e., CMJs) stretch-shortening cycle muscle actions, and during concentric-only explosive muscle actions (i.e., SJs), in both male and female athletes in comparison with a professional contact platform.
