In a randomized, double-blind, placebo-controlled, crossover study involving 15 healthy but sedentary men, supplementation with 100 mg/d coenzyme Q10 for a period of 8 weeks was found to exert performance-enhancing effects during repeated bouts of supramaximal exercises. Subjects completed 5 Wingate tests with 75 g/kg body weight load, with 2 mins between tests, at baseline, after 8 weeks of coenzyme Q10 supplementation, and after 8 weeks of placebo supplementation. In both groups, peak power and mean power decreased and fatigue increased during the Wingate tests. During the Wingate test 5 (WT5), mean power increased after coenzyme Q10 supplementation, and not placebo. In addition, fatigue indexes decreased with CoQ10 supplementation; however, decreases in fatigue index were found with placebo supplementation as well. The results of this study led the authors to conclude that coenzyme Q10 may be beneficial as an ergogenic aid. Additional research is warranted.
