对攀岩运动员不同负荷训练时上肢肌肉疲劳情况的肌电观察

The Evaluating of Surface Electromyography at Different Training Load of the Upper-Limb Muscle Fatigue of Rock Climbing Athletes

通过对攀岩运动员的上肢主要做功肌肉左右腕屈肌、左右腕伸肌的表面肌电信号(sEMG)进行分析,探讨不同负荷的运动诱发肌肉疲劳过程中sEMG信号变化特征及其与肌肉耐力运动的关系。

To analyze the surface electromyography（sEMG） signal of working upper-limb muscle of rock climbing athletes,the paper discusses the different peculiarity of surface electromyography during different training load making fatigue of muscle,and discusses the relations on the peculiarity and the endurance training of muscle.
