摘　　要：目的：观察站桩功核心肌群表面肌电图变化,分析站桩功对核心肌群的影响。方法：采用自身前后对照设计,对30名健康志愿者采用表面肌电信号采集技术分别记录自然站立位和太极拳站桩位核心肌群的表面肌电变化,对每块肌肉的肌电均方根值与其最大随意收缩力肌电均方根值的比值进行分析比较。结果：自然站立位和站桩位竖脊肌上段、腹横肌、腹直肌下段、腹外斜肌左右负荷差异明显（P〈0.05）,核心肌群左右负荷不完全等同;站桩位与自然站立位相较竖脊肌、多裂肌、左侧腹横肌和右侧腹直肌上段肌肉负荷明显增加且具有统计学意义（P〈0.05）,站桩功激活核心肌群肌电,锻炼核心肌群功能。结论：站桩功能维持脊柱稳定性,增强腰背部肌力,有效锻炼核心肌群功能。Objective：To observe the variation of core muscles＇ surface electromyography and analysis the effects between standing Qigong and core muscles. Methods：Before-after study in the same patient was used in this study,and 30 healthy participants were volunteered for this study. Surface electromyography was used to record the variation of stance and standing Qigong. The value of root mean square（RMS）were processed on each muscle and each muscle＇s maximum voluntary contraction（MVC）was used for data analysis. Results：Upper erector spinae,transverse abdominis,lower rectus abdominis,external oblique had significant difference between left and right sides at stance（P〈0.05）,the load of core muscles were not equivalent; erector spinae,multifidus,left transverse abdominis,right upper rectus abdominis had muscle load increased at standing Qigong,and significant difference between stance and standing Qigong（P〈0.05）,standing Qigong excited myoelectric activity of core muscles and improved it function. Conclusion：Standing Qigong maintained the stability of spine,increased muscle strength of lumbar spinal cord and excited myoelectric activity of core muscles.
