The Effects of Four Weeks of CoQ10 Supplement Consumption on VO2max, Anaerobic Power and Specific Endurance in Indoor Soccer Players

The aim of this study was to evaluate the effects of four weeks of CoQ10 supplement consumption on VO2max, peak anaerobic power and specific endurance in indoor soccer players. 14 indoor soccer players (age 21.42±1.69 yr, peak anaerobic power 437.94±54.63 watt, VO2max 48.84±3.87 ml/kg/min) who were experienced in national college championships were randomly divided into two groups where supplement group (N=8) consumed CoQ10 supplement (300 gr/day) and placebo group (n=6) consumed placebo. Both groups trained for four 90-min. sessions per week. Supplement and control groups consumed 300 mg of CoQ10 and placebo respectively daily. Bruce test was performed on a treadmill to measure VO2max and time to exhaustion, Rast test and Hoff test were used to measure peak anaerobic power and specific endurance. The values were obtained before and after the intervention period and compared using student paired and unpaired t tests. Findings showed that after supplement consumption, posttest VO2max did not change in supplement group (from 48.65 ml/kg/min to 51.58 ml/kg/min). Time to exhaustion (from 811.87 seconds to 816.66 seconds) and specific endurance (from 1291.25m to 1381.25m) did not significantly change. It can be concluded that four weeks of CoQ10 supplement consumption could not increase VO2max, time to exhaustion, anaerobic power and specific endurance of indoor soccer players. So the consumers should take this supplement longer so that they can benefit from its positive effects.
