Active and passive intervals (AI, PI) between exercise series promote different hemodynamic responses; however, the impact of these intervals on the blood pressure response has not yet been investigated. The objective of this study was to compare the impact of AIs and PIs during resistance exercises with the magnitude of postexercise hypotension (PEH). Elderly hypertensive women (n = 21, 61.2 ± 2 years of age) completed 4 sessions for upper or lower limbs with AI or PI (3 sets, 15 repetitions, 60% load of 15 repetition maximum (RM), and an interval of 90 seconds between sets). Blood pressure was measured 10 minutes before and at 10, 20, 30, 40, and 50 minutes after the exercise sessions. The heart rate at the end of each AI was always significantly higher than that after the PI, but the perceived exertion as measured by the Perceived Exertion Scale (OMNI-RPE) was similar to that of PI exercise protocols. In the lower limb exercises, AI resulted in significantly and consistently higher PEH than in exercises with PI for both systolic (from 20 minutes postexercise) and diastolic (from 10 minutes postexercise) pressures. The upper limb exercises promoted much more discrete PEH in relation to the lower limb exercises, given that the AI promoted significantly higher PEH relative to the PI protocols, but only for systolic PEH and only from 30 minutes postexercise. This is the first time that AIs between sets in a session of resistance exercises have been shown to be a highly effective methodological strategy to increase PEH in elderly hypertensive women.
主动和被动间隔（AI、PI）在运动系列之间会促进不同的血液动力学反应；然而，这些间隔对血压反应的影响尚未得到研究。本研究的目的是比较阻力运动中 AI 和 PI 对运动后低血压（PEH）幅度的影响。老年高血压女性（n=21，61.2±2 岁）完成了 4 次上肢或下肢的 AI 或 PI 运动（3 组，15 次重复，60%的 15 次重复最大负荷（RM），每组之间间隔 90 秒）。在运动前 10 分钟和运动后 10、20、30、40 和 50 分钟测量血压。AI 结束时的心率始终显著高于 PI 后，但是 OMNI-RPE 感知的用力与 PI 运动方案相似。在下肢运动中，AI 导致的收缩压（从运动后 20 分钟开始）和舒张压（从运动后 10 分钟开始）的 PEH 显著且持续高于 PI 运动。与下肢运动相比，上肢运动引起的 PEH 更为离散，因为 AI 与 PI 方案相比，显著提高了 PEH，但仅针对收缩压 PEH，并且仅在运动后 30 分钟。这是首次表明，在阻力运动中，一组运动之间的 AI 是一种非常有效的方法策略，可以提高老年高血压女性的 PEH。
