title: Effects of programmed physical activity on body composition in post-pubertal schoolchildren.
abstract: OBJECTIVE
  To assess body composition modifications in post-pubertal schoolchildren after practice of a physical activity program during one school year.
  
  
  METHODS
  The sample consisted of 386 students aged between 15 and 17 years and divided into two groups: the study group (SG) comprised 195 students and the control group (CG), 191. The SG was submitted to a physical activity program and the CG attended conventional physical education classes. Body composition was assessed using body mass index (BMI), percentage of body fat (%BF), fat mass (FM), and lean mass (LM).
  
  
  RESULTS
  A positive effect of the physical activity program on body composition in the SG (p<0.001) was observed, as well as on the interaction time x group in all the variables analyzed in both genders. A reduction in %BF (mean of differences = -5.58%) and waist circumference (-2.33 cm), as well as an increase in LM (+2.05 kg) were observed in the SG for both genders, whereas the opposite was observed in the CG.
  
  
  CONCLUSIONS
  The practice of programmed physical activity promotes significant reduction of body fat in post-pubertal schoolchildren.
