Purpose: The present study aimed to examine changes in the sensory and motor processing system in the brains of people who have practiced kendo for a long period of time, based on the P300 amplitude - an event-related potential. Methods: The subjects were five long-term kendo practitioners and five people who had never experienced it. They performed the somatosensory Go/NoGo paradigms task. In the present experiment, images were used as S1, and square-wave electricity as S2. S2 further consists of a Go stimulus applied to the thumb of the left hand and NoGo stimulus. The subjects were asked to grip the handle with the right hand as quickly as possible when the "Go stimulus" was applied, and ignore the "NoGo stimulus". Results: The NoGo P300 amplitude at the F4 site of kendo practitioners was significantly higher than that of people who had not experienced kendo. The NoGo P300 amplitude was significantly higher than the Go P300 amplitude at the F3, Fz, and F4 sites, or the frontal brain region, of kendo practitioners. Discussion: In kendo practitioners, who frequently control their planned movements in kendo matches, the functions of the frontal lobe related to decision-making and behavioral decisions are promoted, which increases the efficiency of the neural activity associated with the control of body movements.
