Whey Protein, but Not Soy Protein, Supplementation Alleviates Exerciseinduced Lipid Peroxidation in Female Endurance Athletes

Purpose: The objective of this study was to assess the protective effects of whey and soy protein supplementa- tion on inflammatory response, oxidative damage and body composition in active female endurance athletes. Methods: Healthy female endurance athletes (18-25 y; n = 18) running at least one hour per day, five days per week were randomly assigned to consume 40 g whey or soy protein daily, in a 6-wk double-blind study. Blood samples were ob- tained following completion of a one hour run at baseline and wk 6, and analyzed for inflammatory and oxidative bio- markers. DXA scans were completed to determine body composition. Results: Whey protein intervention decreased (P< 0.05) plasma TBARS concentrations, indicating suppressed lipid per- oxidation. Supplementation with soy protein had no effect on markers of oxidative damage and inflammation, but de- creased (P< 0.05) reduced glutathione indicating a reduction in antioxidant activity. Protein supplementation had no sig- nificant effect on body composition. Conclusions: Supplementation with whey protein decreased lipid peroxidation in in female endurance athletes suggesting a potential antioxidative action, while soy protein did not improve biomarkers of oxidative damage and inflammation.
