摘要

Purpose

To verify the longitudinal association between leisure-time physical activity (PA) and physical fitness.

Methods

A longitudinal study with 360 schoolchildren (6–17 years; 57.5% female) from Southern Brazil. Data collection occurred in 2014 (baseline) and 2016 (follow-up), respecting a minimum difference of 1 and a half years between assessments. Leisure-time PA at baseline was assessed using a self-reported questionnaire. According to PA recommendations, students were classified as active (≥ 420 min/week) and inactive. The practice of any PA was also considered. Physical fitness tests were carried out at baseline and follow-up, evaluating: lower and upper limb power, flexibility, abdominal resistance, agility, velocity, and cardiorespiratory fitness. The associations were tested by multiple linear regression.

Results

Active students showed better results for the upper limb power (β 0.095; 95% CI 0.036; 0.155), flexibility (β 0.084; 95% CI 0.008; 0.160), and velocity (β − 0.105; 95% CI − 0.039; − 0.024), compared to inactive ones. Furthermore, students who performed any AP showed better results in the assessments of agility (β − 0.088; 95% CI − 0.173; − 0.003) and velocity (β − 0.097; 95% CI − 0.181; − 0.014), than students who do not declare any activity.

Conclusions

Our results highlight the importance of PA programs in childhood and adolescence, encompassing all components of physical fitness.
