NMES的介入對武術騰空雙飛腳的影響

目的：本研究對武術騰空雙飛腳的主要受力肌群進行NMES介入，以啟動肌肉的興奮度，藉此了解NMES介入對騰空雙飛腳重心最低點瞬間、雙腳離地瞬間、騰空雙飛腳瞬間三階段的運動學參數差異。方法：本研究招募師範大學武術隊15名男生作為研究對象，其均掌握武術的基本功和基本技巧，平均身高175.53±4.98公分，平均體重66.87±6.20公斤，平均年齡22.00±1.46歲。結果：重心最低點瞬間時，各運動學參數均無顯著差異（p>0.05）。雙腳離地瞬間時，垂直速度NMES介入後較介入前快，且呈現顯著水準（z=-3.295,p=0.001）；大腿角速度NMES介入後較介入前快，且呈現顯著水準（z=-3.408,p=0.001）；小腿角速度NMES介入後較介入前快，且呈現顯著水準（z=-2.329,p=0.020）。騰空雙飛腳瞬間時，各運動學參數均無顯著差異（p>0.05）。結論：通過NMES訓練對人體肌肉力量提高是有效果的，NMES介入後雙腿力量得到提高，騰空雙飛腳的動作品質要比介入完成的更好。建議未來研究中可以增加實驗對象人數與女性研究對象，也可以藉此在武術基本跳躍動作訓練中輔以NMES介入，進一步提高武術跳躍動作品質，給予教練與運動員做為參考。

Purpose: This study conducts NMES intervention on the main force-bearing muscles of martial arts flying feet in order to activate the excitement of the muscles, so as to understand the effects of NMES intervention on the instant of the lowest point of gravity of the flying feet, the instant when both feet were off the ground, and the instant of flying feet. Differences in kinematic parameters of the three phases. Methods: This study recruited 15 boys from the martial arts team of Normal University as the research subjects. All of them mastered the basic skills and skills of martial arts (Average height 175.53 ± 4.98 cm, weight 66.87 ± 6.20 kg, age 22.00 ± 1.46 years). Results: At the instant of the lowest point of the center of gravity, there was no significant difference in the kinematic parameters (p > 0.05). When the feet were off the ground, the vertical velocity after NMES intervention was faster than that before intervention, and showed a high level of significance (z = -3.295, p = 0.001); the thigh angular velocity after NMES intervention was faster than before intervention, and showed a high level of significance (z = -3.408, p = 0.001); calf angular velocity after NMES intervention was faster than before intervention, and showed a high level of significance (z = -2.329, p = 0.020). There was no significant difference in the kinematic parameters at the instant of the double-flying feet (p > 0.05). Conclusion: NMES training was effective in improving human muscle strength. After NMES intervention, the strength of the legs is improved, the degree of physical fatigue was reduced, and the quality of the movement of flying feet in the air was better than the intervention. It was suggested that in future research, the number of experimental subjects and female research subjects can be increased, and NMES can also be used to intervene in the basic martial arts jumping training to further improve the quality of martial arts jumping movements, and provide coaches and athletes as a reference.
