Condición física y calidad de vida en escolares de 8 a 12 años

Abstract

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.

Análisis de la condición física según sexo, edad, índice de masa corporal y nivel de actividad física en estudiantes de primaria en España

“…17 PA was measured with the Physician-based Assessment and Counseling for Exercise (PACE) 43 instrument, which consists of 2 items that estimate the weekly PA performed by an individual for at least 60 minutes (PACE 1, how many times in the last week; PACE 2, how many days in a typical week). Internal consistency, reliability and validity were verified in individuals of similar ages by Rosa-Guillamón et al 3 , and Cronbach's Alpha for the present study was 0.847.…”

“…Scientific evidence suggests that health status and quality of life in students are directly related to their physical fitness (PF). 1 PF is understood as a set of capacities and functions that allows people to perform physical and sport-based exercises and physical activities with vigour 2 and efficiency 3 in their daily life.…”

“…6 This relationship includes both genetic 25 and lifestyle factors, including a deficit of physical activity (PA) and PF. 3 According to the scientific literature, regular and adequate physical activity is one of the best (complementary) strategies to combat increasing rates of overweight and obesity in children and adolescents. 3,26 Therefore, physical exercise is understood as the practice of PA in a structured, planned, and systematic way with the objective of improving one or more components of PF.…”

“…3 According to the scientific literature, regular and adequate physical activity is one of the best (complementary) strategies to combat increasing rates of overweight and obesity in children and adolescents. 3,26 Therefore, physical exercise is understood as the practice of PA in a structured, planned, and systematic way with the objective of improving one or more components of PF. 25 Although much of the variability of PF is determined by genes, environmental constraints, especially PA, can influence it, 25 perhaps in a two-way relationship.…”

“…25 Although much of the variability of PF is determined by genes, environmental constraints, especially PA, can influence it, 25 perhaps in a two-way relationship. 3 However, whether this relationship is consistent has been questioned, considering that PA performance among young people is characterized by being unpredictable, unsystematic and of short duration and, consequently, may not change the status of PF, especially at the cardiovascular level. 27 In summary, in young individuals, it has been described that being younger, 13,28 female, 17,29 overweight, [30][31][32][33] and having a PA deficit is associated with a worse PF status.…”
