Coenzyme Q10 is a fat-soluble vitamin-like substance that carries electrons in the mitochondria. It plays an important role in anti-oxidant activities and energy production. The aim of this study was to compare the effects of coenzyme Q10 supplementation on aerobic capacity, anaerobic and some selected indicators on Muscle soreness in athletes and non-athletes boys.
This quasi- experimental research was conducted on 20 male students of 60 volunteers with an average age, height and weight, respectively (16.30±0.8 years, 172±6 cm, 62.76±7.55 kg) in two groups: Athletes (n= 10) and non-athletes (n= 10) were classified. Both groups were sampled 4 times (Every time 5cc of the elbow vein) in two steps (before and after serving supplementation) and the basic level and delay soreness index changes (LDH and CK), using Pars laboratory test kit and Autoanalaizer AT- classical alpha were evaluated. The protocol of this study was, Bruce (using a treadmill to assess VO2max) and Faulkner (using the treadmill, V= 12.9 km/h and g= 20, to assess aerobic power). Bruce and Faulkner test reliability was obtained at 0.95 to 0.99 and 0.76 to 0.91, respectively. To examine the differences in the various stages of sampling, as well as intra-group and out-group differences, repeated measure, ANOVA, dependent and independent tests were used.
The findings showed that short-term use of CoQ10 supplements led to no significant change, CK (P= 0.19), LDH (P= 0.12), anaerobic power (P= 0.17) and aerobic power (P= 0.43) in both groups of athletes and non-athletes.
The overall results indicate that the level of physical fitness (compared to the athlete or athletes being), had no effect on aerobic, and anaerobic capacity and muscle soreness due to coenzyme Q10 supplementation. Both groups benefited equally from the supplement.

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.

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.

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.

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.
