高低水平太极拳练习者下肢肌肉用力特征肌电分析
首发时间:2012-01-18
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。

Analysis of the Lower Limb Muscles during Tai Chi training in high-level and ordinary-level Taijiquan practitioners
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.
