一、写在研制之前40年代,Alwell and Elber曾测定中学生和大学生的全身反应时。50年代,Cwreton,T.K 始用弹簧跳台测定声、光、声光同时的全身反应时间,60年代,Fitts,P·M·and Peferson,J·R 进行了反应时间与动作时间的连续测定,猪饲、浅见等借助应力计和肌电图测定了各项运动员、锻炼者和非锻炼者以及一流选手的全身反应时间。另外,还探讨了反应过程中的动作开始时间 First, written in the 40’s before the development, Alwell and Elber had measured the systemic reaction of middle school students and college students. In the 1950s, Cwreton and TK used spring-loaded platform to measure simultaneous systemic reaction time of sound, light, sound and light. In the 1960s, Fitts, PM and Peferson, JR performed continuous determination of reaction time and action time. Feeding, humble opinion, etc. With the help of stress meter and EMG, the body reaction time of athletes, exercisers and non-exercisers as well as first-class players was determined. In addition, the reaction start time was also discussed
