This study investigated the acute blood pressure (BP) effects of different exercise modalities in older adults with hypertension. Sixty volunteers were randomly assigned (n = 15 / group) into different exercise protocols: resistance, bike, water-based exercise (WE), and a control session-all for approximately 45 min. Clinic BP measurements were taken before, immediately after, and 15 and 30 min after protocols. The data were analyzed by one-way analysis of variance; generalized estimating equations, following Bonferroni post hoc (p < 0.05). Immediately after exercise, the systolic BP (SBP) increased in all exercise protocols (resistance exercise = delta 10.3, bike exercise = delta 5.8, WE = delta 9.5 mmHg; p < 0.001), while the diastolic BP was not altered. Afterward, the SBP reached the value observed before exercise. In Minute 30, only WE presented a significant reduction for SBP (WE = delta -4.6 mmHg; p < 0.05). This study has important clinical implications in hemodynamic safety for acute BP increases immediately after exercises, as well as, in the SBP, reduction benefits for older adults with hypertension.
