Blood pressure (BP) and hemodynamic response to heated water-based (HEx) land-based exercise (LEx) were assessed in 15 (6 men) older hypertensives (age 66.4±4.9 yr) under pharmacological treatment. Participants were randomly assigned to perform 30 min of moderate-intensity HEx (walking inside the pool), LEx (walking on a treadmill) and non-exercise control (CON) intervention. Resting BP, arterial stiffness, endothelial reactivity and heart rate variability (HRV) were measured before, immediately after, and 45 min after interventions. 24-h ambulatory BP monitoring was performed after interventions. Resting systolic (but not diastolic) BP reduced 9.9±3.1 mmHg (<0.01) 45 min after HEx only. 24-h systolic and diastolic, daytime diastolic and nightime systolic BP were lower (<0.05) after HEx than both LEx and CON. Daytime systolic BP was also lower (<0.05) after HEx than CON. Nighttime diastolic was not different between interventions. HEx-induced ambulatory BP reduction ranged 4.5±1.3 mmHg (24-h diastolic BP) to 9.5±3.0 mmHg (nighttime systolic BP), and persisted for 18/11 h in systolic/diastolic BP, when compared with CON. No significant changes in arterial stiffness, endothelial reactivity and HRV were found during any intervention. These results suggest that HEx may have important implications for managing BP in older hypertensive under pharmacological treatment.
在接受药物治疗的15名（6名男性）老年高血压患者（年龄66.4±4.9岁）中，评估了血压（BP）和对热水基（HEx）陆地运动（LEx）的血流动力学反应。参与者被随机分配进行30分钟的中等强度HEx（在游泳池内行走）、LEx（在跑步机上行走）和非运动对照（CON）干预。在干预前、干预后立即以及干预后45分钟测量静息血压、动脉僵硬度、内皮反应性和心率变异性（HRV）。干预后进行24小时动态血压监测。仅在HEx后45分钟，静息收缩压（而非舒张压）降低了9.9±3.1 mmHg（<0.01）。与LEx和CON相比，HEx后24小时收缩压和舒张压、白天舒张压和夜间收缩压均较低（<0.05）。HEx后白天收缩压也低于CON（<0.05）。各干预组之间夜间舒张压无差异。与CON相比，HEx引起的动态血压降低范围为4.5±1.3 mmHg（24小时舒张压）至9.5±3.0 mmHg（夜间收缩压），收缩压/舒张压持续18/11小时。在任何干预过程中，未发现动脉僵硬度、内皮反应性和HRV有显著变化。这些结果表明，HEx可能对接受药物治疗的老年高血压患者的血压管理具有重要意义。
