武術側踹腿及側踢動作之生物力學分析

本研究以四名武術散手擂台賽國家代表隊的選手作為研究受試對象。透過比較武術側踹腿及側踢動作，來了解兩組動作之差異性及在比賽過程中所適用之時機點。使用AcqKnowledge Biopack system加速規測量系統對實驗參加者的攻擊力量進行測試，並以二部Redlake motion scope 1000高速攝影機以250HZ的拍攝頻率對實驗參加者的側踹腿及側踢動作進行同步的攝影。在統計方法部分使用相依樣本t檢驗的統計方法，其檢定水準為□=.05。經本實驗後，實驗結果如下：在攻擊力量方面，側踹腿及側踢動作兩者間達顯著差異(t=-4.928，p<.05)，側踢動作在攻擊力量上明顯大於側踹腿。在動作時間方面，雖然側踹腿及側踢兩者間未達顯著差異(t=0.551，p>.05)，但大部分實驗參加者側踢動作時間卻明顯短於側踹腿腿動作，顯示側踢動作相較於側踹腿動作，在攻擊的時機點上具有較佳的優勢。側踹腿及側踢攻擊腿活動順序與人體由大關節到小關節的運動順序及鞭打原理並不相符。原因與其動作型態的專項性及動作不需要克服大的阻力有關。側踹腿主要是透過攻擊腿先屈後伸的蹬腿動作在擊中目標物後對目標物進行攻擊；而側踢動作則比較傾向於是在擊中目標物前因主動肌群作用所獲得的動量來對目標物進行撞擊。

The purpose of this study was to compare push kick and side kick of martial arts. Four martial arts Shanshou national team athletes participated as subjects. The striking power of the side-stamp and side-kick were measured with AcqKnowledge Biopack system. And 2 Redlake motion scope 1000 high-speed cameras were used to film (250Hz) the side-stamp and side-kick of the subjects. Data of the study were analyzed in dependent t-test. The result revealed as following: The striking power of side kick was significantly greater than side-stamp (t=-4.928,p<.05). The movement time of side kick was shorter than side-stamp though not significantly(t=0.551,p>.05). This revealed that side kick was somehow faster than push kicks. The sequence of the joints activated did not conform to the whipping principle. The reason might be the characteristics of the kicks and it was not necessary for the subject to overcome high resistance. The power of side-stamp was generated by flexing and stretching the legs and than pushing the target after contact. Whereas the side kick used the momentum generated by muscles to hit the target.
