Outline of Final Research Achievements

The present study showed that the resistance-trained group demonstrated a higher arterial stiffness, lower arterial compliance, and lower arterial baroreflex sensitivity compared with the control group. In addition, arterial baroreflex sensitivity was inversely and positively correlated with the arterial stiffness and compliance, respectively (Fig 2A and B). These findings suggest that greater arterial stiffness with resistance training may blunt arterial baroreflex sensitivity.

Academic Significance and Societal Importance of the Research Achievements

筋力トレーニングが動脈硬化を引き起こすことが明らかになってから20年になり、その間に多くの研究グループがその「メカニズム」や「予防改善策」に焦点を当ててきた。しかし、この動脈硬化が及ぼす影響まで追求している研究は極めて少ない。筋力トレーニングは骨格筋量の増加および筋力の増強、ひいては寝たきりを防ぐ有効的なトレーニング様式であるため、本研究課題はより安全な筋力トレーニングの処方につながるエビデンスの提供につながると考えられる。
