Values are displayed as means ± s.d. number (percent) or median (percentile 25, percentile 75). For normalized data, comparisons between groups were performed using one-way ANOVA followed by LSD test when applicable. For nonnormalized data, comparisons between groups were performed using Kruskal-Wallis test.
BMI: body mass index; FM: fat mass; FFM: fat free mass; FMi: fat mass index; FFMi: fat free mass index; ST: sedentary time; LA: leisure activity.
