Abstract:
The purpose of this study was to analyse the association of different physical activity indexes, in school (IAFE), organized sports (IAFD) and leisure time (IAFTL), with body fat and physical fitness levels in prepubescent children. The sample consisted of 302 children, 147 boys and 155 girls, aged between 10 and 11 years old (10.81 ± 0.43). Physical activity indexes were evaluated using the Baecke questionnaire. Skinfold thickness measurements and body fat percentage were used in the evaluation of fat mass. With the exception of the IAFTL, there were significant and negative correlations between the different physical activity indexes and the subcutaneous fat mass and body fat percentage. There were significant and positive correlations between the IAFE and the aerobic capacity, strength and muscular endurance, speed and agility; between the IAFD and the aerobic capacity, strength and muscular endurance, speed, agility and anaerobic muscular power; and between the IAFTL and the aerobic capacity and agility. These data may help to better understand the association between the physical activity in different environment and the physical fitness of prepubescent children.
