Abstract
During a judo tournament day, athletes often participate in several matches that are generally separated by a minimum recovery period. Mitochondria-targeted antioxidants such as Q10 may prevent metabolic stress damage by increasing buffering power. However, the effect of Q10 on recovery after judo match is currently unknown. Here, In this study, the acute and chronic effect of Q10 supplementation on lactate, creatine kinase and specific performance after judo match protocol.
Methods: 20 competitive male judokas were selected and randomly divided into two groups: placebo (Dextrose: 2.5 mg/kg/day) and supplement (Q10: 2.5 mg/kg/day). After acute (1day, 2 hours before the judo match) and chronic (21-day supplementation), all subjects were participated in a judo match protocol (three 4-minute simulated judo matches with an interval of 20 minutes). A special judo fitness test (SJFT) was performed 5 hours after last competition. SJFT consists of 3 consecutive rounds (1×15 s, 2×30 s with 10-s recovery intervals between them) of “Ippon-seoinage” throws performed by the judoka on two partners. Lactate was assessed at Pre, Post and 15 min following judo math. Creatine kinase and the number of throws in SJFT were evaluated at Pre and 5 h following judo math. Repeated ANOVA and Bonferuni as a post hoc tests were used for data analysis.
Results: The results showed that acute Q10 supplementation had not significant effect on lactate, number of throws and creatine kinase. The chronic (21-day) Q10 supplementation attenuated the exercise-induced increase in response of the lactate (F=1/614, p=0/041) and creatine kinase (F=0/0804, p=0/013). chronic Q10 supplementation had not any significant effect on number of throws (F=0/679, p=0/126).
Conclusion: Based on the present results, 21-day Q10 supplementation (2.5 mg/kg/day) is more effective than the acute supplementation to overcome the exercise-induced adverse responses in lactate and creatine kinase. Therefore, chronic Q10 supplementation is recommended to improve recovery after judo match.
