• Subjects: Athletes; Background: Quercetin is a bioflavonoid which occurs in many food items. Some previous studies on quercetin showed inconsistent results on exercise performance; Badminton; Bicycling; Biosynthesis; Body composition; Body fat; body fat percentage and VO2 max did not show any significant difference (P > 0/05) after eight weeks of suppl; Body mass index; Clinical trials; Dietary supplements; double blind clinical trial was conducted on 26 badminton players for eight weeks. The subjects were randomly assigned to one of two groups to receive quercetin (1000 mg) or placebo (1000 mg dextrose). VO2 and time to exhaustion (TTE) for measuring performance and body fat percentage (BFP) were measured before and after intervention. Plasma sample swere obtained for the determination of plasma lactate before and after intervention. Results: Lactate concentration; Exercise; Exhaustion; Fatigue; Food science; Food supply; Free radicals; Lactic acid; Males; Metabolism; muscle damage and body muscle in athletes. The aim of this study was to determine the effects of eight weeks of quercetin supplementation on exercise performance; muscle damage indices and body muscle in badminton players.
