碩士 === 國立彰化師範大學 === 運動學系應用運動科學碩士班 === 104 === This study aimed to evaluate the dynamic balance of high school taekwondo athletes. Differences between sexes and legs, in addition to the determinants that cause the difference were examined. 30 male and 25 female taekwondo athletes of high school were recruited to join this study. Each was subjected to the measurements of stature, weight, and a battery of fitness tests consisted of vertical jump, sit-and-reach, hexagon agility test, visual reaction time and the Y-balance test (YBT). Statistical significance was set at 0.05. The results showed the males perform better in the YBT than the females. Leg asymmetry of the dynamic balance was not found both in male and female players. The YBT score was significantly correlated to the vertical jump, stature, age and agility. Stepwise regression analysis showed that 40.8% of the variance of the YBT score of the non-dominant leg can be explained by vertical jump and stature, and 35.2% of the variance of the YBT score of the dominant leg can be explained by stature and age. It is suggested the dissimilarities of the strength and kinematics of the lower extremities are key factors affecting the YBT performance in the male and female taekwondo players.
