Data are mean±SD. ΔAPHV=difference from age at peak height velocity, BM=body mass, BMI=body mass index, BF=body fat, FM=fat mass, FFM=fat-free mass. The symbols *, † and ‡ denote significance level of p<0.05, p<0.01 and p<0.001, respectively, for differences between normal and overweight participants using independent student t-test.
