The purposes of this study were to compare the differences between dominant and non-dominant leg during Slide -Roundhouse kick for elite Taekwondo athletes. Six national Taekwondo team players, 3 males and 3 females, were participated in this study (a mean height of 177.2 ± 7.6 cm, a mean body weight of 67.6 ± 6.8 kg and a mean age of 22.0 ± 2.3 yrs). The dominant leg preference during Slide-Roundhouse Kick was based on the previous questionnaire results. The ground-reaction forces after initiating the movement in all six subjects and the time differences between front leg and back leg takeoffs were measured by two AMTI Force Platforms. The force and speed during kicking were recorded by three-axis accelerometer and one digital camcorder. Differences between both legs in kinematic and kinetic variables were analyzed by using the independent t-test. The finding indicated that the comparison between dominant leg and non-dominant leg in reaction time, motion time, attacking time and takeoff time from both legs between dominant and non-dominant side had no statistical significant differences. In comparison of the impulse from anterior-posterior direction, the front leg from dominant side had a greater impulse volume than non-dominant side. No significant difference in comparison of the ground-reaction force between legs in the vertical direction, however, the ground -reaction force in both vertical and anterior -posterior direction of the back leg is greater than the front leg. The data of speed and force during both legs Slide-Roundhouse Kick showed significant differences. Although the speed of kick speed of dominant leg is faster than non-dominant leg, the force of kick is weaker than non-dominant leg. The result of this study revealed that during the process of kicking in elite Taekwondo athletes still had differences between legs.目　次 第壹章　緒論…………………………………………………………1 　第一節　前言………………………………………………………1 　第二節　問題背景…………………………………………………2 　第三節　研究目的…………………………………………………5 　第四節　研究假設…………………………………………………5 　第五節　研究範圍…………………………………………………6 　第六節　研究限制…………………………………………………6 　第七節　名詞解釋與操作性定義…………………………………7 第貳章　文獻探討……………………………………………………8 　第一節　跆拳道滑步旋踢動作特徵………………………………8 　第二節　踢擊動作之運動學與動力學……………………………9 　第三節　慣用腳與非慣用腳之比較………………………………13 　第四節　文獻總結…………………………………………………16 第參章　研究方法與步驟……………………………………………17 　第一節　研究對象…………………………………………………17 　第二節　研究時間與地點…………………………………………18 　第三節　實驗儀器與設備…………………………………………18 　第四節　實驗流程與步驟…………………………………………22 　第五節　資料收集與處理…………………………………………24 　第六節　統計分析…………………………………………………26 第肆章　結果…………………………………………………………27 　第一節　攻擊動作之反應時間、動作時間和攻擊時間…………27 　第二節　慣用邊與非慣用邊之前後腳離地時間差與 　　　　　地面作用力………………………………………………30 　第三節　攻擊腳之踢擊速度與力量………………………………36 第伍章　討論…………………………………………………………38 　第一節　慣用與非慣用腳之反應、動作和攻擊時間……………38 　第二節　慣用邊與非慣用邊前後腳離地時間差與 　　　　　地面反作用力……………………………………………41 　第三節　攻擊腳之踢擊速度與力量………………………………43 第陸章　結論與建議…………………………………………………46 　第一節　結論………………………………………………………46 　第二節　建議………………………………………………………47 參考文獻………………………………………………………………48 　一、中文部份………………………………………………………48 　二、西文部份………………………………………………………51456658 bytesapplication/pdf滑步旋踢;慣用腳;跆拳道Slide-Roundhouse Kick;dominant leg;Taekwondothesis
