Bottom Line: Among all nonpharmacological treatments, aerobic or resistance training (RT) has been indicated as a significantly important strategy to control hypertension.The purpose of this study was to compare the outcomes of differing intensities of RT on hypertensive older women.No differences were found in diastolic blood pressure and heart rate measures.

ABSTRACT
Among all nonpharmacological treatments, aerobic or resistance training (RT) has been indicated as a significantly important strategy to control hypertension. However, postexercise hypotension responses after intensity alterations in RT are not yet fully understood. The purpose of this study was to compare the outcomes of differing intensities of RT on hypertensive older women. Twenty hypertensive older women participated voluntarily in this study. After a maximum voluntary contraction test (one repetition maximum) and determination of 40% and 80% experimental loads, the protocol (3 sets/90″ interset rest) was performed in a single session with the following exercises: leg press, leg extension, leg curl, chest press, elbow flexion, elbow extension, upper back row, and abdominal flexion. Systolic and diastolic blood pressures were evaluated at rest, during exercise peak, and after 5, 10, 15, 30, 45, and 60 minutes of exercise and compared to the control. Both experimental loads were effective (P<0.01) in promoting postexercise systolic hypotension (mmHg) compared to controls, after 30, 45, and 60 minutes, respectively, at 40% (113±2, 112±4, and 110±3 mmHg) and 80% (111±3, 111±4, and 110±4 mmHg). Both procedures promoted hypotension with similar systolic blood pressures (40%: -11%±1.0% and 80%: -13%±0.5%), mean arterial blood pressures (40%: -12%±5.5% and 80%: -12%±3.4%), and rate-pressure products (40%: -15%±2.1% and 80%: -17%±2.4%) compared to control measures (systolic blood pressure: 1%±1%, mean arterial blood pressure:\ 0.6%±1.5%, rate-pressure product: 0.33%±1.1%). No differences were found in diastolic blood pressure and heart rate measures. In conclusion, hypertensive older women exhibit postexercise hypotension independently of exercise intensity without expressed cardiovascular overload during the session.

Mentions: In addition, the hypotension perceptual effects after 60 minutes comparing to rest were analyzed between efforts exercise and around groups (Figure 3). The hypotensive effects were similar to effort at 40% (SBP: −11%±1.0%, MBP: 12%±5.5%, and RPP: 15%±2.1%) and 80% (SBP: 13%±0.5%, MBP: 12%±3.4%, and RPP: 17%±2.4%) but effective (P<0.01) as compared to control parameters (SBP: 1%±1%, MBP: 0.6%±1.5%, and RPP: 0.33%±1.1%). In relation to DBP (C: 0.41%±1.5%, 40%: 1%±1.8%, and 80%: 1%±0.80%) and HR (C: 1.0%±0.13%, 40%: 1.1%±0.13%, and 80%: 1.2%±0.10%), no differences were found around efforts.
