From: Prior exercise and antioxidant supplementation: effect on oxidative stress and muscle injury

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).
