Lean body mass (a), fat mass (b), lower limb fat-free mass (c), lower limb muscle mass (d), and lower limb fat mass (e). Participants consumed 20 g of their supplementary protein powder after exercise (6 days a week). Changes of body composition from 0 to 4 months were expressed as mean change ±95% CI, and changes completely above or below the baseline are significant changes. *p < 0.05, significant difference between W group and EW group
