Abstract
Purpose: The purpose of this study was to investigate the effect of ribose supplementation on total antioxidant capacity (TAC), lipid peroxidation (MDA) and xanthine oxidase (XO) after repeated intensive exercise in wrestlers. Methodology: For this purpose 10 subjects with mean age (22±3 years) and BMI (23±2 kg/m2) voluntary participated in this study. Research was quasi-experimental and was done in double blind design. The protocol included 4 stages with 15 minutes of active rest; Each stage included three lower and upper extremity Wingate test and with alternative pattern with 1 min active rest between each test. First time ribose or placebo (1/0 gr per kg of body weight) were consumed. Also the second dose of supplement or placebo was give after the end of second stage of test and third dose was given after the completion of fourth stage. Blood sample was taken before and after and one hour after recovery. Findings: Data was analyzed with repeated measure (2×3) and the result showed that ribose supplementation decreased the concentration of MDA significantly after exercise (P=0/001). But regarding to observed result, TAC did not correlate to ribose consumption (P=0/07). Also XO was not related to ribose consumption (p=0/71). Conclusion: Generally it seems that ribose acute supplementation have significant effect on fat peroxidation index.
