摘要

本研究試圖以運動科學的研究方法，對中國舞蹈後踢腿動作加以分析，以瞭解中國舞蹈後踢腿動作中，肌肉動作細微變化，並尋找影響此技巧動作表現的因素。本研究之受試者為自願參與實驗之22名舞蹈系女學生，以肌電圖、荷重元件及關節角度器等工具，評估中國舞蹈後踢腿動作中，肌肉電位變化、主要肌群肌力及柔軟度等對技巧動作表現的影響。結果發現慣用側豎脊肌、臀大肌反應時間大於非慣用側；高表現群總肌電訊號作用時間及二分之一最大強度肌電作用期間皆顯著大於低表現群；高表現群之無肌電訊號反應時間顯著小於低表現群。由本研究可知中國舞蹈後踢腿動作中，非慣用側之臀大肌、豎脊肌等核心肌肉群反應時間較短，以提供技巧動作變化中較佳之穩定度；高表現群舞者運用增加總肌電訊號時間，延長二分之一最大肌電強度時間，並以較大的臀大肌肌力與更佳的髖關節柔軟度為策略，以提高中國舞蹈後踢腿動作表現。因此，舞者可藉由以髖關節周圍肌群為主的核心肌肉群之肌力及柔軟度訓練，以提升中國舞蹈動作後踢腿之動作表現。

Purpose: The purposes of this study were to analyze the technique movement as grand battement derrie in Chinese dance, to examine the tiny change in muscles during this skill, and to know what factor dominate this technique. Methods: Twenty-two female university in dance department students volunteered to participate in this study. Strength of bilateral paraspinatus muscles and gluteus muscles were calculated using load-cells, flexibility of trunk and hip were evaluated by goniometers, and the fine changes of muscular activity were measured by electromyography. All subjects performed eight times of grand battement in Chinese dance and scored by professional dancer to define the esthetics score of this technique. Results: The dominant side exhibited shorter reaction time than non-dominant side in paraspinatus muscles and gluteus muscles, high level group showed longer muscular activity and shorter resting time than lower level group, which were observed by electromyography. Higher level group were significant greater and better than lower level group in gluteus muscular strength and hip flexibility, but not in trunk. There was significant positive correlation between muscular strength of gluteus and score of technique, but not in trunk. There was significant positive correlation between hip flexibility and esthetics score of technique, yet not in trunk. Conclusion: There are faster reaction times in dominate side to provide the stability before motion occurred. The gluteus muscles and hip flexibilities are the key factor for the performance in grand battement derrie in Chinese dance.
