摘　　要：从受试肌群的选取、测试步骤、指标选取和数据处理等方面详细介绍了无线表面肌电测试系统在手枪射击运动员的动作技术诊断中的应用。以国家射击队手枪慢射运动员石兴隆为例,介绍如何从肌电原始信号图、持枪臂各主要肌群参与工作贡献率和击发前三秒肌群肌电平均振幅等方面对手枪运动员持枪臂肌群用力特征和射击动作稳定性进行研究。This paper introduced the application of the wireless surface electromyography test system on pistol ath-letes diagnosis in terms of the selected test muscle, test pro- cedures, selected parameters and data processing. Taking for example a national pistol shooting team member Shi Xin-glong, this paper described how to study pistol athletes＇ gun ann muscle strength characteristics and shooting motion sta-bility in terms of the original EMG signal diagram, the major muscle groups contributions rate and the first three second muscle EMG average amplitude before firing of the gun arm.
