陕西女子摔跤运动员关键技术动作表面肌电研究

A surface EMG research of key technical movement of female wrestlers in Shaanxi Province

运用运动生物力学摄像与肌电图同步测试手段,对我省现役4名高水平女子摔跤运动员在完成摔跤关键技术动作过程中,肌肉表面肌电图(SEMG)进行测试分析,结果表明:她们所测试的肌肉肌电变化有两种不同特征,景瑞雪的肌肉活动具有一定的变化节奏,协调能力较好;其他队员则表现出部分肌肉持续用力的时间较长,协调能力相对较差。肌肉表现出活动与用力程度最大的肌肉为右侧肱二头肌。在完成抱腿摔过程中肱二头肌为主要的用力肌肉。右侧股直肌的活动程度相对较小。

By using the methods of sports biomechanics camera and EMG synchronous test,this paper analyses the EMG of four high-level female wrestlers during doing wrestling key technical movement.The results show that there are two different characteristics of the changes of muscle EMG,the muscle activity of Jing Ruixue has a certain variation rules and coordination ability is better;other members show that partial muscle sustainable exertion time is longer,and coordination ability is relatively worse.The right biceps muscle shows the largest activity and exertion.The biceps muscle is the main exertion muscle in the completed of the crotch fell.The activity degree of right rectus is relatively small.
