| Outline of Final Research Achievements |
This study aimed to detailed clarify changes in the pathways to the information-processing system of the brain of kendo players, as well as their motor nervous and muscular systems, by neuroscientifically examining players with long-term experience of continuously playing kendo using the P300, N140, and NOGO components of brain potentials, collision technique to measure the motor nerve conduction velocity, and electromyography. On comparison with individuals of the general public, kendo players were shown to need markedly less time to activate motor nerves in motor-related brain areas. Their maximum nerve conduction velocity peaked at 46 and 33 m/sec on the dominant and non-dominant sides, respectively. The results suggest the possibility of the maximum nerve conduction velocity changing due to the influence of training.
