Introducción. La condición física (CF) es un importante indicador fisiológico del estado de salud de la población en general y de los escolares en particular.Objetivo. Analizar la relación entre CF y calidad de vida (CV) en una muestra de escolares de primaria.Materiales y métodos. Estudio transversal en el que participaron 298 escolares (159 mujeres y 139 varones) de entre 8 y 12 años de la región de Murcia, en España, durante el periodo 2013-2014. La CF se valoró mediante la batería ALPHA-fitness y su nivel (bajo, medio y alto) fue categorizado con base en estudios previos, la CV se valoró mediante el cuestionario KIDSCREEN-10 Index y para establecer la relación entre ambas variables se realizó un análisis de varianza simple.Resultados. El valor global de la CF se asoció de manera positiva con la CV (F=3.997; p=0.019).Conclusiones. Los resultados sugieren que los escolares con un mejor estado de CF tienen una mayor CV. Se precisan estudios de intervención dirigidos al desarrollo de la CF para evaluar las posibles mejoras en los niveles de CV de los jóvenes.
Objectives: The purpose of this study was to analyze the relationship between general self-concept and health-related physical fitness in primary school children. Design: Cross-sectional design and descriptive court. Method: A total of 216 schoolchildren (9.26 ± 1.26 years) participated in the measurement of the speed-agility, muscle strength and aerobic capacity as physical fitness components. Six dimensions of self-concept (intellectual, behavioral, physical, lack of anxiety, social and life satisfaction) were assessed by the Self-Concept Scale Piers-Harris. Results: No significant differences were found among the self-concept dimensions between men and women. Males showed higher scores on the test of 4 × 10 m (p < 0.05), manual dynamometry (p < 0.005) and Course-Navette (p < 0.005). An increased fitness level was positively and significantly related with higher values of overall self-concept (p < 0.005) in both genres. Conclusion: The results of this study suggest that those students with a higher overall fitness level show higher levels of general self-concept. More investigation is needed to know which physical fitness parameters are more related with the self-concept.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
