奧運跆拳道男子選手專項踢擊能力之量分析－個案研究

本研究利用科學儀器設備，擷取我國參加2004年雅典奧運跆拳道第一量級選手－朱木炎專項踢擊動作之反應時間、動作速度及踢擊力量。測試動作乃依據受試者個人專長或競賽需求決定，包括5項單一中端攻擊動作、3項單一中端反擊動作及3項單一上端攻擊動作。測試中，加速規黏貼於踢擊人形靶背部，受試者選擇一最佳距離並站立於踢擊人形靶前，當全身反應器光源箱發出紅色訊號時，受試者需儘速完成踢擊動作。反應時間會記錄於全身反應器之螢幕上，而踢擊速度由攻擊距離除以動作時間計算取得，踢擊力量則取加速規瞬間產生訊號之最大值表示(√x^2+y^2+z^2)。研究結果顯示：單一中端攻擊動作之反應時間最快為左腳滑步旋踢。動作速度及踢擊力量最佳的動作為右腳中端旋踢。單一中端反擊動作部分，反應時間及動作速度最快之動作為左腳反擊旋踢，踢擊力量最大之動作為左腳反擊後踢。單一上端攻擊動作中，反應時間最快之動作為左腳下壓踢，動作速度及踢擊力量最佳的動作均為左腳上端旋踢。

The purpose of this study was to use scientific instrumentation to monitor Chu Mu Yen's specific kicking performance before Athens Olympic Games. Subject was Olympic athlete and chose kicking movements according to his special skills and necessary of competition. The test movements include 5 middle section attack kicks, 3 middle section counterattack kicks, and 3upper section attack kicks. An accelerometer was attached on the back of dummy to catch time and impact acceleration of dummy. When the test begins, subject standing in front of dummy and chose a suitable distance. Subject has to kick the target of dummy as rapidly as possible while trigger was flashed red light. The reaction time was displaced on monitor of WRM. The kicking velocity was displacement divided by movement time (m/sec). The kicking power was the square root of 3 dimensional impact accelerations of the tri-axial accelerometer while subject kicked the dummy. The result indicated that fastest reaction movements were middle section of left leg slide Roundhouse attack kick, middle section of left leg Roundhouse counterattack kick, and upper section of Roundhouse attack kick. The fastest velocity movements were middle section of right leg Roundhouse attack kick, middle section of left leg Roundhouse counterattack kick, and upper section of Roundhouse attack kick. The greatest kicking power movements were middle section of right leg Roundhouse attack kick, middle section of left leg back counterattack kick, and upper section of Roundhouse attack kick.
