目的:本研究目的為比較不同的羽球殺球球速下,肘關節及腕關節之角速度差異及與球速間的關聯程度。方法:本研究以14名男子羽球選手為受試者,進行正拍式殺球,利用三維動作捕捉系統(VICON)及測速槍,進行共20次的殺球測驗,進行關節角速度與球速分析。實驗數據以SPSS 20.0統計軟體進行單因子變異數分析(One-way ANOVA)與皮爾森相關係數(Pearson correlation coefficient)分析。結果:結果顯示,隨著球速的提高腕關節角速度也隨之增加,且與球速間達顯著正相關(r=.959*, p<.05),肘關節角速度則與球速無顯著性相關(r=-.219, p>.05)。結論:腕關節角速度的提升可明顯地增加殺球球速。
The purpose of this study was to evaluate the relationship between shuttle velocity and arm motion during badminton smash. Methods: Fourteen healthy male college students were required to forhand smash for 20 times by using badminton racket, using three-dimensional motion capture system (VICON) and the speed gun. The data were analyzed by Pearson correlation analysis with SPSS 18.0 statistical software. Results: Analysis results showed that the shuttle velocity was associated with a significant angular acceleration of the wrist (r=.959, p<.05). No correlation shuttle velocity with a significant angular acceleration of the elbow (r=-.219, p>.05). Conclusion: Enhance of the angular velocity of the wrist can significantly increase the speed of badminton smash.
