Success of taekwondo athlete's was evaluated by the rate of gaining international, national medals and so on. Descriptive statistical and pearson correlation were used for analyzing data. The result showed that, there was a significant relationship between balance (p<0.05, r= 0.486), back flexibility (p<0.05, r=0.474), anaerobic power (p<0.05, r=0.559) and elite male taekwondo athletes success. According to this results, successes in taekwondo needs to numerous factors and male teaekwondo athletes must have excellent waist flexibility to gaining wide range of motion at waist, having continuity on keeping balance to creation of conceesive kicks at the balanced postures, and finally high level of anaerobic power to performing fast and explosive kicks and other skills.
