| 摘要: | 本研究目的為探討“核心力量”訓練對芭蕾技巧Grand Rond de jambe en láir的改善。本研究假設在介入“核心力量”訓練後，能增進舞者對芭蕾技巧－Grand Rond de jambe en láir的執行能力，包括增加靜態髖外旋角度、增加髖外旋及外展肌力，並能使舞者Grand Rond de jambe en láir動作更具完整性。方法：本研究對象為大學舞蹈系女學生20位，分為實驗組10位學生，對照組10位學生，測試共為3種：1、利用Motion Analysis Corporation (100Hz)擷取運動學資料，2、以手持式肌力測量器測量髖外旋及外展肌力，3、以手持式關節角度器測量靜態髖外旋角度。對照組未作任何訓練，而實驗組介入核心力量訓練的方法：運用彈力帶及大籠球和沙袋加強髖關節開度的訓練，為期八週，每週1個半小時，為舞者提高Adagio類動作的能力，施以一系列的輔助訓練的方案。統計方法使用SPSS統計軟體，以平均值(MEAN)及標準差(SD)呈現受試者基本資料及所有試驗數據資料，以混合設計2因子變異數分析(2有無訓練情況ⅹ2前後測)考驗有無訓練情況以及介入訓練前後各項參數之差異顯著性，統計顯著水準皆定為α=.05。根據研究目的，研究結果與結論，獲得綜合結論如下：
1. 透過“核心力量”訓練對芭蕾技巧－Grand Rond de jambe en láir動作效果有顯著的進步。
2. 透過“核心力量”訓練對芭蕾舞者外旋肌力效果有顯著的進步。
3. 透過“核心力量”訓練對芭蕾舞者外展肌力效果有顯著的進步。
4. 透過“核心力量”訓練對芭蕾舞者靜態髖外旋角度效果有顯著的進步。
由研究結果顯示八週核心力量動作訓練，對於舞者在身體穩定控制的能力有明顯的提升，是可以應用在舞者軀幹身體核心肌群之輔助訓練方法。以上研究結果能提供教學者不同的輔助訓練方法，藉由核心力量動作的訓練，讓學習者對身體有更清楚更快速的學習，進而提升舞蹈之表現力。
The aim of this study was to improve a ballet dancer’s performance in Grand Rond de Jambe en Láir through “core strength training”. It was hypothesized that with “core strength training”, dancers could execute adagio exercises such as Grand Rond de Jambe en Lair more precisely. Such training would enhance the hip rotation, increase lateral rotation, and hip abduction, which makes perfect the Grand Rond de Jambe en Láir from the beginning to the end.
Twenty undergraduate dance major students were chosen to participate in this study: ten of them were in an experimental group who received intervention, and the others were in a control group who received no training. There were three methods used in this study: 1.) use Motion Capture (100 Hz) developed by Motion Analysis Corporation to collect and analyze kinematic data, 2.) use handheld muscle strength measurement to measure hip lateral rotation and abduction strength, 3.) use handheld goniometer to measure hip external rotation in static. The intervention of this core strength training also used elastic exercise bands, a core stability ball, as well as a sand bag to increase the degree of turnout within the pelvis area. Each session was one and a half hours weekly for a total of eight weeks. There were a series of training to assist dancers with improving their ability performing adagio exercises.
The data from each training session and testers’ basic information was entered in SPSS statistical software. These were shown in the average (mean) and standard deviation (SD). The analysis depended on: 1.) whether training was received and 2.) the data collected before and after training. The results of the statistical significance level, after considering the differences between groups and before and after the intervention, was set at alpha = .05.
In conclusion, this study proved the following:
1.) Through the core strength training, the ballet dancers had improved their ability in performing Grand Rond de Jambe en Láir as well as adagio exercises;
2.) Through the core strength training, the ballet dancers had enhanced their external hip rotation;
3.) Through the core strength training, the dancers had increased the degree of lateral rotation;
4.) Through the core strength training, the dancers had gained control of hip abduction.
The research showed that the eight-week core strength training intervention had improved the dancers’ stability and control of their body, and such intervention could be applied in training a dancer’s core muscle group. This study not only provided supplementary training methods to dance teachers, but also refined dancer’s Adagio movements and performance more precisely and quickly after receiving the core strength training. |
