Outline of Final Research Achievements

I considered the lag between physical acceleration and Heart rate variability to reflect the coordination between physical acceleration and the autonomic nervous system. Therefore, I researched the mechanism of those connections including sleep quality with reflecting the mental performance.
I concluded that the coordination between Heart rate variability and physical acceleration diminished by fatigability in younger in the hour before sleep.
I also found that close associations between high oxygen desaturation index and discoordination between HRV and physical acceleration may be due to higher parasympathetic nervous system activity after waking.

Academic Significance and Societal Importance of the Research Achievements

独自指標である自律神経活動―身体加速度の％Lag0指標を睡眠に関連することができたため、より臨床現場での活躍に近づけた可能性を考える。
朝方の副交感神経活動が夜間睡眠にとどまらず、前夜の行動に影響を受ける結果が示唆されたため、朝方の疲労感や倦怠感の原因を考える上での一端を担える可能性がある。
