太极拳锻炼对老龄人双下肢骨骼肌IEMG影响的研究

The Effect of Taijiquan Exercise on the IEMG of the Lower Limbs Skeletal Muscles in the Elderly

目的:了解不同锻炼年限24式简化太极拳练习中下肢左右侧骨骼肌的参与状况。方法:采用芬兰造16导Mega6000型便携式肌电图仪,对18名老龄人进行24式简化太极拳运动中下肢骨骼进行积分肌电图(Integral electromyography IEMG)量化评定测试。结果:对照组右侧胫骨前肌和股外侧肌IEMG大于左侧,实验组右侧股内侧肌和股外侧肌IEMG大于左侧、左侧臀大肌IEMG大于右侧;对照组右侧下肢胫骨前肌承受的负荷相对较大;太极拳锻炼缺乏对股二头肌、腓肠肌等大腿和小腿后群肌力的练习。结论:对照组在练习太极拳后更应当注意对右侧胫骨前肌、股外侧肌的放松练习,实验组更应当注意对右侧股内侧肌和左侧臀大肌的放松练习以消除疲劳,同时本研究对太极拳的合理化锻炼提供一定指导意义。

Objective:To investigate the participation status of the left and right skeletal muscles of the lower limbs in the Simplified 24-form Taijiquan practice by investigating different exercise years.Method:A 16-conductor Mega6000 portable electromyograph made in Finland was used to perform an integral electromyography(IEMG)quantitative assessment test on the lower extremity bones of 24 elderly Taijiquan exercises in 18 elderly people.Results:The IEMG of the right tibialis anterior and lateral femoral muscles of the control group was larger than the left side.The IEMG of the right lateral femoral and lateral femoral muscles of the experimental group was greater than that of the left and left gluteus maximus IEMG.The load on the anterior muscle is relatively large;Taijiquan exercise lacks exercises on the thigh and calf muscles of the biceps femoris and gastrocnemius.Conclusion:After practicing Tai Chi,the control group should pay more attention to the relaxation exercise of the right tibialis anterior and lateral femoral muscles.The experimental group should pay more attention to the relaxation exercise of the right medial femoral muscle and the left gluteus maximus to eliminate fatigue.At the same time,it provides guiding significance for the rationalization exercise of Taijiquan.
