NCT01444170

Brief Summary

The objectives of this study are to assess the effectiveness of a nutritional supplement on muscle functional recovery following induced muscle damage from high intensity resistance exercise. The investigators hypothesize that a short-term dietary supplementation will significantly improve muscle functional recovery following an intense bout of eccentric exercise compared to a placebo.
