Article: 9 | Published online: 06 May 2022

Figures & data

Table 1 Characteristics of 30 resistance trained men.

Table 2 Timeline to investigate the effects of prior exercise and antioxidants on muscle injury and oxidative stress.

Table 3 Dietary intake of resistance trained men before and following the eccentric exercise protocol.

Figure 1 Creatine kinase activity (A), C-reactive protein (B), protein carbonyls (C) and peroxides (D) before and following an acute bout of eccentric resistance exercise in trained men. No prior exercise + placebo (NoP); no prior exercise + antioxidant (NoA); prior exercise + placebo (ExP); prior exercise + antioxidant (ExA). No significant group differences noted for any variables (P > 0.05). A time main effect was noted only for creatine kinase activity (P < 0.0001).

Figure 2 Muscle soreness (A), maximal isometric force (B), peak velocity (C), and maximal dynamic force (D) before and following an acute bout of eccentric resistance exercise in trained men. No prior exercise + placebo (NoP); no prior exercise + antioxidant (NoA); prior exercise + placebo (ExP); prior exercise + antioxidant (ExA). No significant group differences noted for any variables (P > 0.05). Time main effects were noted for muscle soreness, maximal isometric force, and peak velocity (P < 0.0001).
