dc.description.abstractThis study investigated the effects of vigorous physical activity (VPA) and VPA-dose response on percent body fat (%BF) and cardiorespiratory fitness (CRF) between high and low adiposity children. The study data were obtained from a randomized controlled physical activity (PA)-based childhood obesity prevention --- Medical College of Georgia FitKid Project (MCG FitKid). The 40-minute VPA session from MCG FitKid was used to investigate the effects of VPA on %BF and CRF. The program attendance was used to quantify the dose of VPA (< 15 min/d VPA and 15 min/d VPA). A total of 498 participants were included in this study. Based on median split of baseline %BF, participants were split into high and low adiposity levels. Mixed-model ANOVA was used to test study hypotheses. There was no significant difference between high-adiposity intervention children and other three subgroups (low-adiposity intervention children, high and low adiposity children in control groups) on %BF and CRF changes. There was a significant difference between high-adiposity children with 15 min/d VPA and high-adiposity children with < 15 min/d VPA on %BF changes. There was no significant difference between high and low adiposity children with the same dose of VPA on %BF and CRF changes. The results suggested that 15 min/d could be an effective VPA dose to lower %BF in children with high-level adiposity. It remains unclear whether there are differential impacts of VPA on high-adiposity and low-adiposity children.
