Abstract
Aim: This study aimed to investigate the effects of short-term supplementation with coenzyme Q10 (CoQ10) on markers of oxidative stress and inflammation, specifically superoxide dismutase (SOD), malondialdehyde (MDA), and interleukin-6 (IL-6), following exhaustive aerobic exercise in judo athletes.
Method: Sixteen male judo athletes participated in a randomized, double-blind, crossover study in which they received CoQ10 or placebo. Participants received CoQ10 supplementation for 30 days after completing a first bout of exhaustive aerobic exercise, then completed a second bout of exhaustive exercise. Blood samples were collected before exercise, immediately, and 24 hours after exercise during the two bouts to measure levels of SOD, MDA, and IL-6. These markers were analyzed using enzyme-linked immunosorbent assay (ELISA) and spectrophotometric techniques.
Results: CoQ10 supplementation significantly increased SOD levels after 30 days of supplementation compared to the placebo group (p<0.05). MDA and IL-6 levels were significantly reduced during the recovery period after CoQ10 supplementation (p<0.05). These findings suggest that CoQ10 effectively enhances antioxidant defences and reduces lipid peroxidation and inflammation induced by exhaustive aerobic exercise.
Conclusion: CoQ10 supplementation improves oxidative stress and inflammatory responses in judo athletes after exhaustive aerobic exercise. CoQ10 may be an effective nutritional strategy to enhance recovery and reduce exercise-induced cellular damage in high-intensity sports
