電刺激對武術正踢腿的即時效應研究

目的：探討立即性電刺激對武術正踢腿表現的影響。方法：招募師範大學武術專選班8名男性學生作為實驗對象，平均身高175.88±5.82公分，體重66.50±6.65公斤，年齡21.63±0.92歲。實驗過程中將17顆感測器裝置於研究參與者身上，並利用慣性式動作捕捉系統完成運動學參數之蒐集。每位受試者第一次測驗（T1）盡最大努力完成正踢腿動作，第二次測驗（T2）先進行30分鐘的NMES介入，再盡最大努力完成正踢腿動作（T1與T2需間隔72小時以上）。以描述性統計計算平均數和標準差，再以Wilcoxon signed-rank test檢驗T1與T2運動學參數差異，顯著水準定為α=.05。結果：在離地瞬間時，大腿加速度T2大於T1且呈現顯著水準（z=-2.521, P=.012）。其他各運動學參數均無顯著差異（P>.05）。結論：武術正踢腿動作技術方面，NMES的介入效果明顯優於傳統訓練，顯著提升了離地瞬間的大腿加速度。透過對肌肉柔韌性和力量的雙重調節，NMES介入有助於使正踢腿動作更加流暢且有效。然而短時間的NMES介入為本研究限制，為了全面評估其效益，建議未來研究深入探討週期性與較長時間的NMES介入訓練成效。

Purpose: To explore the effect of immediate electrical stimulation on the performance of forward kicking in Wushu. Methods: Eight male students from the special Wushu class of Normal University were recruited as experimental participants (average height 175.88 ± 5.82 cm, weight 66.50 ± 6.65 kg, age 21.63 ± 0.92 years old). During the experiment, 17 sensors were installed on the research participants, and an inertial motion capture system was used to complete the collection of kinematic parameters. Each participant tried his best to complete the forward kicking action in the first test (T1), and in the second test (T2), he had 30 minutes of NMES intervention first, and then tried his best to complete the forward kicking action (T1 and T2 need to be separated more than 72 hours). Descriptive statistics were used to calculate the mean and standard deviation, and then Wilcoxon signed-rank test was used to test the differences between T1 and T2 kinematic parameters, and the significance level was set at α = .05. Results: Thigh acceleration T2 was significantly greater than T1 at the instant of liftoff (z = -2.521, P = .012). There were no significant differences in other kinematic parameters (P > .05). Conclusion: In terms of martial arts positive kicking technique, the intervention effect of NMES was significantly better than that of traditional training, and it significantly improves the thigh acceleration at the moment of leaving the ground. Through dual regulation of muscle flexibility and strength, NMES intervention helps make the forward kicking movement smoother and more effective. However, short-term NMES intervention is a limitation of this study. In order to comprehensively evaluate its effectiveness, future research is recommended to further explore the effectiveness of periodic and longer-term NMES intervention training.
