Outline of Final Research Achievements

Community-dwelling older adults participated in a program as a part of the training group (30-minutes aerobic exercise and lower-limb resistance exercises using one’s body weight, 3 times/week, 6 weeks) or the control group (asked not to modify their lifestyle). Systolic blood pressure (SBP) during a one-hand arm curl exercise at 20% and 40% one-repetition maximum was lower after versus before the intervention in the training group. Additionally, aerobic capacity, muscular strength and endurance, and arterial stiffness improved with the exercise training in the training group. These results suggest that combined aerobic and low-intensity resistance exercise training decreases SBP during resistance exercise in older adults.

Academic Significance and Societal Importance of the Research Achievements

本研究は複合運動トレーニングにより抵抗性運動時の血圧が低下することを示した初めての研究である．抵抗性運動時血圧は比較的簡便に測定でき，安静時血圧よりもトレーニング効果に鋭敏なので，トレーニング効果の新たな指標に発展する可能性がある．抵抗性運動時の血圧は仮面性高血圧症および将来の高血圧発症との関連が指摘されており，また，抵抗性運動は日常生活動作に多く含まれている．本研究は，運動トレーニングの新しい価値を示したものであるとも言える．
