| Summary: | 碩士 === 國立臺灣體育運動大學 === 競技運動學系碩士班 === 104 === This research aims to analyze the characteristics of Taekwondo’s side kick, sliding side kick, and sliding back side kick by comparing the differences between the reaction times and the execution times. Six male and six female athletes from National Taiwan University of Physical Education and Sport’s Taekwondo representative team participates in this study. Each athlete performs all three side kick techniques. This research uses Vicon System to analyze the biomechanics, two impact force sensor Kistler plates to analyze the mechanics and kinematics, and Dae Do Electric Scoring Equipment to measure the impact forces. The statistical data are analyzed using one-way analysis of variance (one-way ANOVA). The research concludes multiple results. There are no significant differences among the three kicks when comparing athlete’s reaction times. Side kicks have the fastest execution times and overall times. There are no significant differences among three kicks when comparing the absolute impact forces and the relative impact forces when data are normalized for athlete’s weights. There are no significant differences among the three kicks when comparing the fastest speeds of the joint with the largest angle of the athlete’s lower extremities. When athletes perform sliding back side kicks, their bodies tilt later than side kicks or sliding side kicks. There are no significant differences among the three kicks when comparing the summation of the forces acting upon the non-kicking legs. Side kicks have the smallest knee joint angles and ranges, but this difference compared to sliding side kick’s and sliding back side kick’s is not significant.
