BACKGROUND: Heavy exercise cause muscle damage associated with production of inflammatory agents. The purpose of present study was to determine the effect of acute and 14-day Coenzyme Q10 supplementation on inflammatory, blood lactate and muscle damage in male middle-distance runners.

METHODS: Eighteen male middle-distance runners in a randomized and quasi experimental study were allocated into two equal groups: supplement group (n=9, Coenzyme Q10: 5mg/kg/day) and placebo group (n= 9, Dextrose: 5mg/kg/day). After acute (1day) and 14-day supplementation, all subjects were participated in a training like running (competitive 3000 meters). Blood samples were obtained in the four phases: one hour before and 18-24 hours after two running protocols. Lactate, serum interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP) and creatine kinase (CK) were analyzed. Repeated ANOVA and Bonferuni as a post hoc tests were used to determine the changes in four stages. Differences between groups were determined by t-test.

RESULTS: The results showed that acute and short-term Coenzyme Q10 supplementation had not significant effect on basal parameters. The acute coenzyme Q10 supplementation attenuated only the exercise-induced increase in response of the plasma CRP. The short-term (14-day) coenzyme Q10 supplementation attenuated the exercise-induced increase in response of the lactate, serum interleukin- 6, tumor necrosis factor-alpha, and CRP in male middle-distance runners. However, the acute and short-term coenzyme Q10 supplementation had not any significant effect on the exerciseinduced increase response of total serum creatine kinase.

CONCLUSION: Based on the present results, it can be concluded that the 14-day coenzyme Q10 supplementation ( is more effective than the acute supplementation to overcome the exercise-induced adverse responses in some oxidative, inflammatory and biochemical parameters. Therefore, short-term coenzyme Q10 supplementation is recommended to reduce exercise-induced adverse consequences.
