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.
本研究旨在探讨不同运动方式对高血压老年患者的急性血压（BP）影响。60 名志愿者被随机分配到不同的运动方案中（n = 15/组）：阻力、自行车、水上运动（WE）和对照组——所有方案均持续约 45 分钟。在方案前、后即刻以及 15 和 30 分钟时测量诊所 BP。采用单因素方差分析对数据进行分析；采用广义估计方程，随后进行 Bonferroni 事后检验（p <.05）。运动后即刻，所有运动方案的收缩压（SBP）均升高（阻力运动=Δ10.3mmHg，自行车运动=Δ5.8mmHg，WE=Δ9.5mmHg；p <.001），而舒张压没有改变。之后，SBP 恢复到运动前的水平。在第 30 分钟时，只有 WE 方案的 SBP 显著降低（WE=Δ-4.6mmHg；p <.05）。本研究对高血压老年患者运动后即刻急性血压升高的血流动力学安全性以及 SBP 降低具有重要的临床意义。
