  Background: The purpose of the present study is to investigate the effect of Chronic L-Carnitine Supplementation on Exercise Performance, Blood Lactate, and Exercise-Induced Oxidative Stress in Resistance-Trained Males Materials and Methods: We examined 35 resistance-trained (1y) male participants (25±2y, 79.8±8.9 kg, 16.1±5.53% body fat) for 9-wk of L-carnitine supplementation in conjunction with resistance training on exercise performance, blood lactate, and exercise-induced oxidative stress. Randomized, placebo-controlled, double-blind treatment of a (1) no intervention, no supplement Control (CON, n=12), (2) maltodextrose Placebo (PLA, 2 g/d, n=11) or (3) L-carnitine (LCR, 2 g/d, n=12). Exercise performance, post-exercise blood lactate (BL) and oxidative stress markers were analyzed at weeks 3, 6, and 9. The PLA and LCR groups followed a specific resistance training program (4 d/w, upper body/lower body split) for a 9-wk. Data were analyzed by GLM and presented as mean (SD) or change (95% CI). Primary outcomes were total lifting volume for the bench (BP) and leg press (LP). Results: The results a significant increase in BP lifting volume at wk-6 (139 kg, 95% CI 49.1, 230) and wk-9 (238 kg, 95% CI 132, 343) for LCR. Similar results were observed for LP. We also observed a significant increase in Wingate mean power (63.4 W, 95% CI 30.5, 96.3) and peak power (239 W/kg, 95% CI 104, 374) at wk-9 for LCR as well as a significant reduction in post-exercise BL levels and oxidative stress responses. No differences were observed in body composition. Conclusion: These findings indicate that LCR supplementation improves exercise performance and attenuates the blood lactate and oxidative stress response to resistance training. تفاصيل المقالة

  Background: Reactive oxygen species are produced in response to strenuous, prolonged exercise, such as swimming, which results in cell damage. The aim of this study was to compare the effect of antioxidant and coenzyme 10Q supplementation on some indicators of muscle injury in water polo boys. Materials and Methods: The 24 boy water polo players with at least 5 years of training experience and in the age range of 17 to 23 years were randomly divided into three groups )8 people (of vitamin C, coenzyme Q10 and control. Subjects in the vitamin C group (500 mg of vitamin C tablets) and subjects in the coenzyme Q10 group (300 mg of coenzyme Q10 tablets) were consumed daily with food for two weeks. Trainings were performed for two weeks, 6 sessions per week and 90 minutes per session. Evaluation of CK, LDH and AST indices in the state of at least twelve hours of fasting was performed in three stages: previous, immediately and 24 hours after the completion of the protocol. One-factor analysis of variance test with repeated measures was used. Results: The results showed that CPK decreased significantly after fourteen days of supplementation in coenzyme Q10 group and increased significantly 24 hours after the last training session and in vitamin C group after fourteen days of supplementation and 24 hours after the last training session increased significantly. There was no significant difference in LDH and AST levels between the groups (P <0.05). Conclusion: It seems taking coenzyme Q10 supplements may possibly reduce some indicators of muscle damage after water polo training. تفاصيل المقالة
