Key result
At 30 minutes post-exercise, only water-based exercise produced a significant reduction in systolic blood pressure (Δ-4.6 mmHg; p < .05) among older women with hypertension.
Why the study?
The acute blood pressure effects of different exercise modalities in older adults with hypertension had not been established.
Do different modalities of exercise (resistance, bike, water-based) reduce acute blood pressure in older adults with hypertension compared to a control session?

Mean Difference: -4.6
p-value: p=<.05
Water-based exercise uniquely provides a significant reduction in systolic blood pressure 30 minutes post-exercise in older adults with hypertension, despite an initial acute increase in blood pressure seen across all exercise modalities.
Transient post-exercise SBP rises warrant monitoring in older hypertensives; leaves open whether water-based exercise confers sustained BP benefit.
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 ∼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 < .05). Immediately after exercise, the systolic BP (SBP) increased in all exercise protocols (resistance exercise = Δ10.3, bike exercise = Δ5.8, WE = Δ9.5 mmHg; p < .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 = Δ-4.6 mmHg; p < .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.

Cunha et al. (2021) conducted an RCT in Hypertension (n=60). Resistance, bike, and water-based exercise vs. Control session was evaluated on Systolic blood pressure change at 30 minutes post-exercise (Δ-4.6 mmHg, p=<.05). At 30 minutes post-exercise, only water-based exercise produced a significant reduction in systolic blood pressure (Δ-4.6 mmHg; p < .05) among older women with hypertension.
