Brief Summary

This study examines the effects of a 16-week structured physical activity program on physical fitness, steps number, and body mass index in children aged 8 to 10 years. Participants were randomly assigned to either an intervention group that participated in the physical activity program or a control group that continued with their usual daily activities without additional intervention. Physical fitness outcomes include standing broad jump, handgrip strength, and 20-meter shuttle run performance. Body mass index is calculated from measured height and body mass. The goal of the study is to determine whether participation in a multicomponent physical activity intervention leads to greater improvements in physical fitness, steps number, and body composition compared with no additional intervention.

Conditions
