Asociación entre indicadores de condición física, estatus de peso corporal y riesgo metabólico en escolares de secundaria / Association between indicators of physical fitness and body weight status in high school students

Introducción: los componentes de la condición física han cobrado suma importancia para determinar problemas de salud en los escolares. Objetivo: analizar la asociación entre indicadores de condición física (ICF), estatus de peso corporal y riesgo metabólico en escolares de secundaria. Métodos: estudio de corte transversal donde se evaluaron 531 escolares, 271 mujeres (51 %) y 260 hombres (49 %) de entre 11 y 15 años. Se utilizaron la batería Alpha Fitness para analizar los ICF y la prueba Pacer para la estimación del VO2máx, y se midió la circunferencia de la cintura (CC) como indicador de obesidad y de riesgo metabólico. Los alumnos se clasificaron según su IMC y CC. Resultados: los ICF muestran un pobre desempeño en la totalidad de los escolares en las variables de flexibilidad (81 %), abdominales (97,7 %), flexión de brazos (95,3 %), velocidad (99,2 %) y VO2máx (64,8 %). Los escolares obesos presentan significativamente un menor desempeño en flexibilidad, fuerza y velocidad (< 0,001) en comparación con los escolares no obesos. Por otra parte, se presenta una relación negativa entre la CC como indicador de riesgo metabólico y la flexibilidad, los abdominales y las flexiones de brazos. Son los hombres quienes presentan mayor riesgo metabólico a diferencia de las mujeres. Conclusiones: la relación entre los ICF y la obesidad pone en evidencia que los escolares con mayor IMC y mayor riesgo metabólico son los que presentan menor desempeño. Es por ello por lo que las políticas educativas deben enfocarse en mejorar los componentes de la condición física para disminuir la obesidad y el riesgo metabólico en los escolares. (AU)

Introduction: the components of physical fitness have become very important to determine health problems in schoolchildren. Objective: to analyze the association between physical condition indicators (PCIs), body weight status, and metabolic risk in high school students. Methods: a cross-sectional study where 531 schoolchildren were evaluated — 271 women (51 %) and 260 men (49 %) between 11 and 15 years old. The Alpha Fitness battery was used to analyze PCIs and the Pacer test to estimate VO2max; waist circumference (WC) was measured as an indicator of obesity and metabolic risk. The students were classified according to their BMI and WC. Results: PCIs showed a poor performance in all schoolchildren in the variables of flexibility (81 %), sit-ups (97.7 %), push-ups (95.3 %), speed (99.2 %) and VO2max (64.8 %). Obese schoolchildren have significantly lower performance in flexibility, strength and speed (< 0.001) when compared to non-obese schoolchildren. On the other hand, there is a negative relationship between WC as indicator of metabolic risk and flexibility, sit-ups, and push-ups. Men are at higher metabolic risk than women. Conclusions: the relationship between HCI and obesity shows that schoolchildren with higher BMI and higher metabolic risk are those with lower performance. That is why educational policies should focus on improving the components of physical fitness to reduce obesity and metabolic risk in schoolchildren. (AU)

Analysis of the Factors That Influence a Quality Physical Education in Mexico: School Supervision's Perspective.

Different international organizations have spoken out in favor of the value of physical activity in the integral development of children and adolescents, which is why different guidelines have been established for governments to facilitate quality Physical Education. In this sense, the objective of this study was to analyze the factors that influence the performance of PE teachers, from the perspective of pedagogical technical advisors and school district supervisors from various school zones from the State of Chihuahua. This was a transversal study, with a qualitative approach and phenomenological focus, which was chosen because it allows the understanding of these aspects from a unique and unrepeatable process; data collection was carried out through focus groups in which PE ATP supervisors participated and data were collaboratively analyzed. The main results indicated that Physical Education does not have the same importance as other subjects, a situation that is reflected in: constant curricular reforms, administrative inconsistencies, dependence on the school organization, and being seldom taken into account in decision-making. It was concluded that strict public policies are required to be applied uniformly throughout the country, as well as privilege Physical Education within the Basic Education curriculum in Mexico.

Mexican physical education teacher's self-reported and self-perception of teaching style / Auto-percepción y auto-reporte de estilos de enseñanza en profesores de educación física mexicanos / Autorrelato e autopercepção do estilo de ensino do professor mexicano de educação física

ABSTRACT To understand the self-reported and perception of teaching style used among Mexican physical education teachers. Participants included 104 (n=41 females and 63 males) elementary physical education teachers from northern Mexico. Results showed that a traditional teaching style tends to be mainly used either by male and female's physical education teachers. Showing differences between genders and teaching styles. Female teachers tend to combine a traditional teaching style with one that connects with students engaging in physical activity, developing positive values and attitudes. Cultural context plays an important aspect when developing a teaching self-perception.

Assessing the Relationship between Autonomy Support and Student Group Cohesion across Ibero-American Countries.

Teacher-endorsed supporting behaviors present themselves as key influencers of student adaptive academic and social functions. The objective of this paper was twofold. First, this study sought to test a model in which student-perceived autonomy support was associated with group cohesion, considering the mediating role of basic psychological needs satisfaction and intrinsic motivation. Second, the current study examined the dimensionality of the model across five Western countries, namely Spain, Portugal, Brazil, Chile, and Mexico. A convenience sample of 3033 college students (Mage = 21.51 ± SD = 3.71) were recruited for the analysis. The results revealed that perceived autonomy support was positively associated with needs satisfaction, being consequently associated with intrinsic motivation and, ultimately, with group cohesion. Additionally, a multigroup analysis revealed that the model was invariant across college students from the different countries. The current results are discussed around the promotion of teacher uses of autonomy-supportive behaviors fostering adaptive outcomes in students regarding positive social relations and that the cultures of Ibero-American countries are equivalent in this process.

How is my teaching? teaching styles among Mexican physical education teachers / Bomo está meu ensino?: estilos de ensino entre professores de educação física mexicanos / ¿Como es mi enseñanza?: estilos de enseñanza entre docentes mexicanos de educación física

Abstract Purpose: To compare teaching styles (TS) and years of experience among Mexican Physical Education (PE) teachers. Method: 129 PE teachers from the City of Chihuahua completed the Teaching Styles in Physical Education questionnaire; average age: 42.3 (±9.6) years; average time teaching PE: 15.7 (±7.9) years. Subjects were divided in 6 groups according to years of experience: -6, 6-11, 12-17, 18-23, 24-29 and 30+. Results: no differences were found in traditional TS among groups, but all PE teachers showed high tendency to use that TS. The 30+ group showed values higher than 6-11 (p<0.05). Conclusion: There is a tendency to implement a traditional teaching style, although years of experience allow PE teachers to use teaching styles that fit students' needs and their interest to participate in Physical Education classes.

Resumo Objetivo: comparar estilos de ensino (EE) e anos de experiência entre professores de Educação Física (EF) mexicanos. Método: 129 professores de EF da cidade de Chihuahua, média de idade: 42,3 anos (± 9,6) anos; experiência como professor de EF: 15,7 (± 7,9) anos; completaram o Questionário sobre EE em EF. Os sujeitos foram divididos em seis grupos de acordo com os anos de experiência: - 6, 6-11, 12-17, 18-23, 24-29 e 30+. Resultados: não foram encontradas diferenças em EE tradicional por grupo, mas todos os professores de EF mostraram tendência elevada a usar esse EE. O grupo 30+ apresentou valores superiores ao grupo 6-11 entre estilo cognitivo e escala criativa (p <0,05). Conclusão: há uma tendência a implementar o EE tradicional, embora os anos de experiência permitam aos professores de EF usar um EE ajustado às necessidades e interesses dos alunos em participar do curso de EF.

Autoconcepto físico, género y cuidado de la salud en universitarios mexicanos / Autoconceito físico, genero e cuidado de saude em universitários mexicanos / Physical self-concept, gender and health care in Mexican university students

Esta investigación, mediante modelos de ecuaciones estructurales, analiza los efectos directos e indirectos del género y el cuidado de la salud sobre el autoconcepto físico. La muestra total fue de 938 universitarios mexicanos, con una edad media de 20.46 años (DE=1.83). Los resultados indican que el género y los hábitos saludables son las variables con mayor poder explicativo sobre la competencia motora y el atractivo físico. También destaca la capacidad mediadora del estrés entre los hábitos no saludables y el autoconcepto físico. Futuras investigaciones deberían replicar estos hallazgos en muestras más amplias (AU)

This research, through structural equation models, analyze the direct and indirect effects of gender and health care on physical self-concept. The total sample was of 938 Mexican university students, with an average age of 20.46 years (SD = 1.83). The proposed model obtains a satisfactory fit. Being significant the majority of the hypothesized relationships. Gender and healthy habits are the variables with greater explanatory power over motor competence and physical attractiveness. It also emphasizes the mediator capacity of stress between unhealthy habits and physical self-concept. Future research should replicate these findings in larger samples (AU)
