The purpose of this study was to investigate and evaluate balance abili-ty, isokinetic moments, and physical fitness according to the growth pe-riod from middle school to university in male taekwondo players. Thirty- five taekwondo players (middle school, n=11; high school, n=15; uni-versity, n=9) participated in this study. The anteriorposterior and medi-al-lateral CoP displacement at balance ability was better in university players than in high school and middle school players. The isokinetic knee joint muscle strength of the right extension and flexion % body weight (BW) at 60°/s was higher in university players than in high school players. The average power of right flexion BW at 180°/sec was higher in middle school players than in high school players. Back strength was higher in university players than in middle and high school players. The repeated jump was higher in high school players than in middle school players. The standing broad jump was higher in university players than in middle school players. The side-step was higher in university players than in high school players. The average power and total energy of an-aerobic power were higher in university and high school players than in middle school players. The peak drop in anaerobic power was higher in middle school players than in high school players. Based on the results of the present study, the growth period should be considered when ap-plying training such as balance, isokinetic moments, and physical fitness to male taekwondo players.
