An increase in blood pressure (BP) occurs during resistance exercise; attention to this response may be necessary in older individuals with hypertension. We compared the BP responses following high- (HSRE) and moderate-speed resistance exercise (MSRE) (4 × 8 repetitions at 60% one-repetition maximum) and control protocol in 15 older adults with hypertension. HSRE and MSRE increased systolic BP (SBP) by the end of each set compared with preexercise and control protocol. Immediately after the fourth set, a higher SBP was observed in MSRE than HSRE (147 ± 14 vs. 141 ± 12 mmHg; p = .01). Taking an exploratory analysis of the individual response, we observed that MSRE resulted in greater mean changes and number of SBP exposures to values ≥150 mmHg (22-fold) than HSRE (10-fold). Diastolic BP increased (p < .05) with exercise, but only MSRE increased compared with the control condition (p < .05). HSRE may be an alternative for individuals in which SBP peak should be avoided.
血压（BP）在抗阻运动中升高；对于患有高血压的老年人，可能需要注意这种反应。我们比较了 15 名高血压老年患者进行高强度（HSRE）和中速（MSRE）阻力运动（60%一次最大重复次数的 4×8 次重复）以及对照方案后的血压反应。与运动前和对照方案相比，每组结束时 HSRE 和 MSRE 都会使收缩压（SBP）升高。在第四组结束后，MSRE 时的 SBP 高于 HSRE（147 ± 14 比 141 ± 12 mmHg；p =.01）。对个体反应进行探索性分析，我们观察到 MSRE 导致 SBP 暴露于≥150 mmHg 值的平均变化和次数大于 HSRE（22 倍比 10 倍）。运动时舒张压升高（p <.05），但只有 MSRE 与对照条件相比有所升高（p <.05）。对于需要避免 SBP 峰值的个体，HSRE 可能是一种替代方法。
