碩士 === 國立彰化師範大學 === 運動健康研究所 === 101 === This study aimed to compare the dynamic balance and strength of the lower extremities between adolescent karate and taekwondo athletes. 30 karate athletes (17.1±1.1 years) and 30 taekwondo athletes (17.0±0.6 years) participated in the study. Dynamic balance was evaluated bilaterally by using the star excursion balance test (SEBT). The anterior (A), postero-medial (PM), and postero-lateral (PL) reach distances of the left and right legs were measured, and then normalized with the leg length. Isometric strengths of knee and ankle were measured by a hand-held dynamometer. Data were analyzed by SPSS18.0, with independent-samples T-test, paired T-test and Pearson correlation coefficient were used. An alpha level of .05 was used for all analyses. The results showed that karate athletes performed better in SEBT test and isometric strengths of knee than the Taekwondo athletes. Moreover, SEBT performance was moderately correlated with the knee extension strength, and lowly negative correlated with the weight and height. The better performance of karate athletes may be attributed the deep squat emphasized in the training and competition. On the other hand, it is suggested the taekwondo athletes need to improve the dynamic balance and strength of the legs, in respect to injury prevention.
