Data are expressed as mean ± standard deviation. P (TxG): group-by-time interaction (p < 0.05). Two-factor repeated-measures ANOVA. *: Significant difference between study points (T1 vs. T2). p < 0.05. PLG: Placebo group; CrMG: Creatine monohydrate supplemented group; HMBG: HMB supplemented group; CrM-HMBG: Creatine monohydrate plus HMB supplemented group.
