 高低水平太极拳练习者下肢肌肉用力特征 肌电分析# 何辉，熊开宇* 5 10 15 20 25 30 35 40 （北京体育大学教学实验中心，北京 100084） 摘要：本研究利用肌电测试技术完成测试，分析高水平 24 式太极拳练习者下肢肌肉肌电特 征，以及低水平练习者与其存在的主要差异，为低水平太极拳练习者提高太极拳水平提供参 考。研究方法：用 ME-6000 肌电仪与摄像机对 8 名高水平和 8 名低水平太极拳练习者进行单 套 24 式太极拳测试；用 MegaWin 软件并结合同步视频对 24 式太极拳整体套路下肢肌肉进行 肌电分析。数据统计学分析采用独立样本 T 检验、配对样本 T 检验。研究结果：高水平组完 成 24 式太极拳，下肢肌肉放电较多的为股内侧肌、股外侧肌、阔筋膜张肌、胫骨前肌、股 直肌；下肢左右侧肌肉积分对比都无显著性差异。研究结论：高水平组 24 式太极拳主要用 力肌肉为股内侧肌、股外侧肌、阔筋膜张肌、胫骨前肌、股直肌；左右侧下肢承受负荷均衡。 关键词：太极拳；表面肌电；积分肌电 中图分类号：G804.2 Analysis of the Lower Limb Muscles during Tai Chi training in high-level and ordinary-level Taijiquan practitioners HE hui, XIONG Kaiyu (Beijing Sport University Teaching Experiment Center, Beijing 100084) Abstract: IThrough using the method of electronic test this study attempts to conclude the lower limb muscle EMG features of high levels of 24-style Taijiquan practitioners,and analyzing the differences existed between the higher-level and the lower-level practitioners,and providing refrence for the low-level practitioners to improve the level of Tai Chi Chuan. Methods:Simultaneous ME-6000 apparatus and videotaping to the experiment of one set of 24-style Taijiquan for eight the higher-level and the lower-level practitioners,the study analyze the features of the lower limb muscle EMG in a whole 24-style Taijiquan by MegaWin software with simultaneous video.Data statistics processing uses independent samples t test and paired samples t test.Results: The iEMG of vastus medialis and vastus lateralis tensor and fascia lata and tibialis anterior and rectus femoris is more in a whole 24-style Taijiquan of the low-level group; there is no significant difference between left and right side lower extremity muscles; there is fluctuating changes in muscle iEMG during 24-style Taijiquan and the peak and the trough appear at the same time. Conclusions: Vastus medialis and vastus lateralis tensor and fascia lata and tibialis anterior and rectus femoris the main force muscle in a whole. Keywords: Taichiquan; sE
