Figure 6. Protein expression of endogenous antioxidant enzymes before and after a period of exercise training and either placebo or resveratrol supplementation in aged men.

Protein expression of catalase (CAT), gluthatione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1), superoxide dismutase 2 (SOD2) and NAD(P)H oxidase (NOX) in homogenates from m. vastus lateralis. Data are presented as mean ± SEM. *Significantly different from pre training; ^$significant effect of time (P < 0.05).
