The effects of daily coenzyme Q10 supplementation on VO2max, vVO2max and intermittent exercise performance in soccer players

The aim of this study is to assess aerobic, anaerobic and performance indexes changes after a short period of coenzyme Q10 Supplementation in soccer players. 16 soccer players (Weight 57.1±20.72, height 171.4±4.92, and age 22.30±1.41) randomized and divided into two groups. Where supplement group (N=10) consumed CoQ10 supplement (300 mg/day) and placebo group (n=6) consumed placebo. Both of them practiced for 4 weeks and each one 90 minutes. After that, supplement group started to consume CoQ10 in amount of 300 mg/day for one month. Findings has been showed that 4-week supplement consumption caused significant changes in VO2max and performance in soccer players, while this intervention did not result in significant effect in body composition, maximum running speed, peak anaerobic power and fatigue index. The major findings of the present study were that 4-week of CoQ10 supplement consumption in college soccer players led to increase aerobic power and performance in high intensity aerobic interval test. From the other point of view, these variations were not significant in placebo group. We can conclude that although increase in maximum running speed (vVO2max) was not significant, four weeks of CoQ10 supplement consumption may increase in maximal oxygen consumption and performance in college soccer players. Finally, in this case consumption of this supplement could improve player's performance in competition conditions.
