Aim: This study aims to examine the effects of oral coenzyme Q10 (CoQ10) on preventing the accumulation of lactic acid developing during the exercise performances of endurance skiing athletes. Materials and Methods: The study population was composed of 15 volunteering male athletes. The blood samples thus collected were utilized for the measurement of athletes’ CoQ10, lactate, lactate dehydrogenase (LDH), creatine phosphokinase (CPK), heart rate and blood pressure. Results: Significant decreases were identified in the systolic and diastolic blood pressures, pulses and plasma lactate levels of the athletes in the trial group when their pre- and post-exercise results were compared (p<0,01; p<0,001) while an increase of p<0,01 was observed in their plasma CoQ10 levels. However, plasma LDH and CPK levels of the trial group athletes using 100 and 200 mg CoQ10 were observed to increase less when compared to the results of the control group athletes in seven days (p<0,001; p<0,01). Conclusion: regular and gradual exercise is considered to enhance physical performance depending on the usage of CoQ10 while it decreases the accumulation of La and thus delays fatigue.
