NCT02281851
Lead Sponsor
University of Birmingham
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Difference in Resting Levels of Endogenous Antioxidant Proteins in Skeletal Muscle - Superoxide Dismutase 2 (SOD-2)Protein concentrations will be measured at baseline only

To examine the effects of habitual vitamin and antioxidant supplementation on endogenous antioxidant production, participants will have a muscle biopsy taken at rest to examine any differences in endogenous antioxidant protein concentrations
