| Outline of Final Research Achievements |
In this study, we focused on spinal excitability in order to elucidate the mechanism of increase in muscle stiffness. Muscle stiffness increased after muscle cooling, but there ware no significant changes in spinal excitability during and after muscle cooling. The resuluts suggested that spinal excitability does not affect the increase in muscle stiffness accompanying peripheral changes.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では，スポーツやリハビリテーション領域で苦慮する筋スティフネス（硬度）増加のメカニズムを解明するために，脊髄興奮性に着目した実験を行った．その結果，末梢部分の変化による筋スティフネスは影響を及ぼさないことが明らかとなった．この結果より，末梢部分の変化による筋スティフネス増加には他の要素が影響していると考えられる．
