摘　　要：要全面准确分析运动技术,了解运动规律,必须实现各种运动生物力学测试手段的同步检测。本文设计和制作的电路,分别同时给予处在正常工作状态下的SEMG和摄像机以单脉冲信号和光信号,从而实现间接同步。In surface electromyography （SEMG）, the electrical activity of individual muscles or muscle groups is detected amplified and analyzed by a computer. However, each method has its advantages and disadvantages. At this point of view, how to design and combine the different kinds of biomechanical methods for analyzing sports techniques more exactly is becoming increasingly important. In this paper, a novel electrocircuit was designed and described in an easy-to-be-understood way, which offered single pulse signal and the light signal to the SEMG and the camera simultaneously when all the equipments were in normal state. The expected synchronization of the biomechanical test was fulfilled.
