Examining Endogenous Antioxidant Levels in Well Trained Cyclists

The Effects of Habitual Antioxidant Supplementation on Endogenous Antioxidants and Oxidative Damage in Well Trained Cyclists

This study will investigate whether increased habitual intake of antioxidant supplements effects the concentration of endogenous antioxidants, the response of antioxidants to exercise, and differences in oxidative damage compared to a non-supplemented group.
