武術不同難度旋風腿之運動學分析

Tornado Kick with Full Twist and Tornado Kick with One and Half Twist Motion Analysis with Martial Art

摘要


目的:本研究在探討A級與B級旋風腿的擊響前跟擊響後軀幹轉動角速度與跳躍高度之差異。方法:本研究徵求10名大專武術選手,分別進行A級與B級旋風腿動作各五次,使用7台紅外線攝影機收集動作數據,並以SPSS20.0軟體以獨立樣本T檢定分析A級與B級旋風腿的跳躍高度跟擊響前後軀幹角速度。結果:在不同等級旋風腿之擊響後角速度與跳躍高度皆達顯著性差異(p=.00),而擊響前角速度則無達顯著性差異(p>.05)。結論:A級與B級旋風腿在擊響前為保持動作結構,故角速度未達顯著,而為達成B級旋風腿動作,在動作初增加跳躍高度跟擊響後增加轉動速度,故擊響後轉動速度跟跳躍高度上達到顯著。

Purpose: The purpose of this study was to investigate differences between Whirlwindkick with full twist and Whirlwind-kick with one and half twist by the data of the angular velocity of body rotation and the height of jumping. Methods: Adopting seven VICON infrared cameras to gain the data, ten active female players separately finished Whirlwindkick with full twist and Whirlwind-kick with one and half twist five times each one. The independent sample t-test examined the height and angular velocity of full twist and one and half twist when slapping before and after. Results: The height of performances and turning velocity when slapping before and after of Whirlwind-kick with full twist and Whirlwind-kick revealed significant difference (p=.00). Conclusions: Before slapping, Whirlwind-kick with full twist and Whirlwind-kick with one and half twist did not reveal significant in the turning velocity in order to keep the structure of the motions. Increasing the jumping height when beginning and the turning velocity after slapping were for the purpose of achieving Whirlwind-kick with one and half twist.
