Outline of Final Research Achievements

Recently, the attitudes regarding exercise for patients with chronic kidney disease are shifting from exercise restriction to exercise therapy. Exercise prescription is needed to ensure safe and effective exercise for patients with chronic kidney disease to obtain the beneficial effects from habitual exercise. The purpose of this study is to examine the influence of moderate-intensity continuous exercise on renal hemodynamics. A single bout of moderate-intensity continuous exercise did not induce the decrease in renal blood flow. There were no significant changes in kidney damage and injury parameters before and after exercise, in the recovery phase. Our findings demonstrate that a single bout of moderate-intensity continuous exercise maintained renal blood flow and did not induce kidney damage and injury.

Academic Significance and Societal Importance of the Research Achievements

今日、慢性腎臓病患者に対する最適な運動トレーニングプログラムは未だに確立されておらず、腎臓への負担を最小限に抑える安全で効果的な運動条件も十分に整備されていない。慢性腎臓病患者に対する安全で効果的な運動条件の解明は透析導入や医療費増大の抑制に向けた喫緊の課題である。本研究で我々は中強度の持続運動が腎血流量を維持し、いかなる腎損傷および障害を誘発しないことを明らかにした。本研究成果は腎機能低下予防のための効果的な運動プログラムを作成するための重要なデータとなり、社会的意義が高いと思われる。
