| Outline of Final Research Achievements |
The purpose of this research project was to comprehensively analyze the physical functions of patients with chronic heart failure, such as cardiorespiratory response, muscle activity, autonomic nerve activity, and peripheral hemodynamics of lower limb skeletal muscles, when exercising on a supine ergometer exercise machine, and to consider exercise programs based on the differences in exercise load in patients with chronic heart failure.
As a result, differences were found in the blood flow velocity of the dorsalis pedis artery, muscle activity of the tibialis anterior muscle, and sympathetic nerve activity in patients with chronic heart failure compared to seated ergometer exercise. Furthermore, double products and perceived exertion showed exercise load responses equivalent to those of seated ergometer exercise, suggesting that supine ergometer exercise is an exercise style with a similar cardiac load.

本研究の成果は，臥位エルゴメーター運動機器を活用した運動が，自律神経調整の破綻が生じやすい慢性心不全患者において，積極的な運動負荷を処方する前段階として取り組む運動様式としての有用性が示唆された．そのため，さらに運動の介入期間や慢性心不全の重症度分類の適応性を明らかにすることで，臥位エルゴメーター運動を臨床的に実用できる手がかりになると推察できる．
