Transient exhaustion of the voluntary movement accompanied by sensation of fatigue was investigated by mean of discharge pattern of the single NMU, using the electro-myographic technique, with the object to obtain a glimpse into the cause. 1. Subjects were ordered to make intensive muscular work, and when they felt it impossible to continue if further, discharge pattern of the single NMU was sought. The pattern showed remarkably larger fluctuation than before the work, and as the result the τ-S relation tended to deviate remarkably to the left as compared with the inital one. 2. There was some difference between the upper and lower limb in this tendency, being more remarkable in the latter. 3. The leftward shift returned to the normal pattern, after some time, but it seemed to take longer time than the recovery from exhaustion of the vertebral motoneuron. From these facts it was estimated thet the cause of transient exhaustion of the voluntary movement accompanied by sensation of fatigue must be sought in the nerval circuit which governs the γ system.
