Abstract:
The aim of this semi-experimental study was to examine the effects of 2 and 4 weeks of CoQ10 supplementation on the ventilator threshold and respiratory compensation point in Young male endurance athletes. Fourteen (22.4±1/2 y, 12.5±4.4 fat percent, 53.3±2.7 ml.kg-1.min-1) young male athletes randomly were divided into two equal groups (n=7). In a double-blind four weeks study, experimental group and control group consumed 60 mg/daily CoQ10 and dextrose, respectively. Two groups performed Iliev GXT on the treadmill to measure ventilator threshold (VT) and respiratory compensation point (RCP) on the 1, 14 and 28 days. Respiratory gases collected automatically through the gas analyzer breath by breath and VO2, VCO2 and VE recorded. VO2 equivalent to VT and RCP automatically calculated at 15s intervals. Analysis of variance and Bonferroni post hoc test (within group), independent t test (between groups) have been used (P0.05). In none of the groups, RCP hadnt a significant difference in three stages (F(2,12)=1.19, P=0.34). Therefore, supplementation with 60 mg/d CoQ10 for either 2 or 4 weeks had no significant effects on the ventilator threshold (VT) and respiratory compensation threshold (RCP) in young male endurance athletes.
