Data presented as mean ± SD. One-way ANOVA for weight (p < 0.001, η2p: 0.67), height (p < 0.001, η2p: 0.63), BMI (p < 0.001, η2p: 0.40), BFMI (p < 0.001, η2p: 0.22), and FFMI (p < 0.001, η2p: 0.48). Significant differences from previous age model (post hoc comparison Fisher’s LSD): *p < 0.05, **p < 0.01, ***p < 0.001. BFMI, body fat mass index; CV, coefficient of variation; FFMI, fat-free mass index; X ± SD, mean ± standard deviation.
