| Outline of Final Research Achievements |
It has been suggested that rapid and high-intensity movements may include decreased muscle activity (muscle relaxation), but few reports have been reported. In this study, we focused on the sharp forward step combined with an attack technique performed in kendo and karate, and conducted research using electrophysiological methods and optical motion capture system. As a result, it was found that rapid and powerful forward stepping movements include a vertical downward motion of the body by momentary relaxing the front leg, and this motion may be included in the brain's motor preparation. The results of this study are expected to contribute to the improvement of movements not only for athletes but also in various fields such as helping children acquire motor skills and preventing the decline of motor abilities in middle-aged and elderly people.
