This study examined whether plasma total glutathione levels could explain the intersubject variability in the creatine kinase (CK) response to eccentric exercise. We hypothesized that the increase in plasma CK activity after eccentric exercise would be lower for individuals with low plasma total glutathione (<2.5 micromol x L-1) compared with individuals with high total glutathione (>3.8 micromol x L-1), but other indicators of muscle damage would be the same between groups.
