Abstract: The aim of this study was to determine the effects of six weeks of quercetin supplementation on exercise performance, muscle damage indices and body muscle in boxer. It included 20 voluntary male athletes. The sportsmen were separated into two groups as the control group (n = 10) and Quercetin group (n = 10). The athletes were supplemented with 500 mg quercetin for six weeks before their exercise programs. Before (B.T.) and after (A.T.) the training, blood samples were taken from athletes in order to determine aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), glutamyl transpeptidase (GG), lactate dehydrogenase (LDH), Creatine kinase (CK) enzyme activities and VO2max. According to the findings, there was no significant difference detected between the groups when they were compared before exercise; however, there were a decrease in the VO2max levels of the control group (P<0.01) and a significant increase in the VO2max levels of quercetin group (P<0.001) when they were compared after being given quercetin. In addition, significant increase (P<0.01) were obtained in the levels of AST, ALT, ALP, GG, LDH and CK of the control group compared to those of the quercetin group. As a result, Trial group AST, ALT, ALP, DD, while the LDH and CK levels are the liver and muscle enzyme activity compared to controls low VO2max levels was concluded to be due to the use of Quercetin be higher.
