VAS score (A) and CIR (B) throughout the experiment. VAS score was used as subjectively assessment of muscle soreness in the exercised arm. CIR value as an indirect marker of muscle damage is presented as differences from the respective BEx. Both parameters were also shown as the AUC from BEx to Day4. Abbreviations: VAS, visual analog scale; AUC, area under the curve; CIR, upper arm circumference. Data are expressed as means ± S.E. *P < 0.05 versus the PLCB group by one-way ANOVA. a,b,c,d show the significant difference compared with the corresponding Pre in the PLCB, BCAA, TAU, and COMB groups, respectively, and single and double characters mean P < 0.05 and P < 0.01, respectively, by repeated measures ANOVA.
