  Background : Delayed onset muscle soreness (DOMS) is a common experience after unusual activities (particularly eccentric exercises ). The aim of the present study was to investigate the effect of short-term consumption of CoQ10 supplement on DOMS in athletic and nonathletic boys aged 15 to 17 years.

  Methods : Twenty athletic and non-athletic boys who had no muscle soreness history in previous six months, voluntarily participated in this study and were assigned into two groups of 10 athletic and 10 non-athletic boys . Physical activity program for DOMS was 70 forearm eccentric contractions . Duration of every contraction was 3 seconds and between two contractions they rest for 10 seconds . Also, they had one minute rest between every 10 contractions . Dependent variables ( LD H and CK ) at baseline ( before) and 48h after exercise soreness were measured . For data analysis ANOVA with repeated measure was used and p ≤ 0.05 was considered as significant .

  Results : Delayed soreness was investigated by measuring the biochemical changes of studied enzymes and self-report factors (i.e. muscle strength, fatigue, and stinging pain). Statistical analysis showed that there were no significant changes in LDH and CK levels of athletic and non-athletic groups (p ≤ 0.05). Both groups’ verbal representation showed that the short term consumption of CoQ10 yields reduction of muscle pain, stinging and fatigue.

  Conclusion: Short term consumption of CoQ10 supplement reduces the levels of main markers of DOMS and muscle pain and fatigue , but this decrease was not significant .
