Abstract(in English) While muscle fatigue appears to be a common phenomenon and experienced in everyday life, the mechanism of its sensation is elusive. In this study, we investigated the hypothesis that fatigue sensation is not only generated by physiological changes and sensory information signaling muscle metabolic state but also modified by information processing of sensorimotor system. In the experiment, subjects answered the change in the sense of fatigue during continuous cyclic finger movement with visual feedback. Results revealed that the muscle fatigue sensation was enhanced with delay of visual feedback of their finger movement, and that this sensation was not ascribed to simple misinterpretation of delay perception because both score tunings against delay were quite different. It is also unlikely that changes in movement intensity caused the enhanced sensation of fatigue because the delay affected neither muscle activity level nor movement phase. Accordingly, we suggest that prediction of motor output based on motor command generation is involved in sensation of muscle fatigue.
