武術旋子轉體之運動生物力學機制

Study of Biomechanics of Spinning Butterfly in Wushu

摘要


旋子轉體是武術套路中最具代表性的動作之一。旋子轉體動作分為助跑、起跳、擺腿、空中轉體、落地等五個階段,其中助跑階段與起跳階段重點在於水平速度的增加與垂直速度的轉換,擺腿跟空中轉體在於減少轉動慣量以達到增加角速度進而完成轉體動作。在落地階段盡量要求兩腳同時落地已達到穩定落地減少失誤。本文就旋子轉體之動作程序與競賽評分規範及旋子轉體動作的生物力學機制進行探討。教練與選手可透過了解武術旋子轉體之運動生物力學機制,再適當調整訓練方法,以便有效且正面的幫助運動員的學習以及技術表現。

The spinning butterfly is one of the most classical actions in Wushu. The movement could be separated into run-up, take off, leg swing, twist during flight, and landing phases. In the run-up and take off phases, the martial artists need to increase the horizontal velocity and vertical velocity at crucial point. Consequently, the leg swing and twist during flight phases are aimed to reduce the moment of inertia to improve the angular velocity for body twist. Finally, the athletes are required to simultaneously landing in the field with both foots during the landing phase to reduce the mistakes and increase the stability. In this study, the rules and movement procedures were discussed. Thus, the coaches and athletics should have an insight into the biomechanics of spinning butterfly in Wushu and modification on training programs to advance in motor learning and improve the performances.
