Eleven subjects reacted to a randomly timed auditory stimulus by extending their right elbows as rapidly as possible under agonist muscle normal state, pretensed and relaxed conditions. Integrated electromyography (emg) was used to validate and quantify muscle state. Total reaction time was divided into premotor reaction time and motor reaction time components, and elbow movement time was measured under all conditions. Significant differences were observed in the integrated emg between the pretensed and relaxed experimental conditions. Differences were observed in total reaction time and premotor time, but not in motor reaction time or movement time.
11名受试者在主动肌正常状态、预收缩和放松状态下，对随机定时的听觉刺激做出反应，尽可能快地伸展右肘。采用表面肌电图（emg）来验证和量化肌肉状态。总反应时间分为运动前反应时间和运动反应时间成分，并在所有条件下测量肘部运动时间。在预收缩和放松实验条件下，表面肌电图积分值存在显著差异。在总反应时间和运动前时间上观察到差异，但在运动反应时间或运动时间上未观察到差异。
