Background Continuous aerobic exercise (CE) is one of the main non-pharmacological recommendations for hypertension prevention and treatment. CE is safe and effective to reduce blood pressure chronically, as well as in the first few hours after its performance, a phenomenon known as post-exercise hypotension (PEH). Interval exercise (IE) also results in PEH. Objective This systematic review and meta-analysis sought to compare the magnitude of PEH between CE and IE in adults. Methods A systematic review of studies published in journals indexed in the PubMed, Web of Knowledge, Scopus and CENTRAL databases was performed until March 2020, which compared the magnitude of PEH between CE and IE. PEH was defined as between 45-60 minutes post-exercise. The differences between groups on blood pressure were analyzed using the random effects model. Data were reported as weighted mean difference (WMD) and 95% confidence interval (CI). A p-value <0.05 was considered statistically significant. The TESTEX scale (0-15) was used to verify the methodological quality of the studies. Results The IE showed a higher magnitude of PEH on systolic blood pressure (WMD: -2.93 mmHg [95% CI: -4.96, -0.90], p = 0.005, I2 = 50%) and diastolic blood pressure (WMD: -1,73 mmHg [IC95%: 2,94, -0,51], p= 0.005, I2= 0%) when compared to CE (12 studies, 196 participants). The scores of the studies on the TEXTEX scale varied from 10 to 11 points. Conclusions The IE resulted in a higher magnitude of PEH when compared to CE between 45 and 60 minutes post-exercise. The absence of adverse event data during IE and CE in the studies prevents comparisons of the safety of these strategies. (Arq Bras Cardiol. 2020; 115(1):5-14).
持续有氧运动（CE）是预防和治疗高血压的主要非药物建议之一。CE 安全有效，可长期降低血压，在运动后数小时内也可降低血压，这种现象称为运动后低血压（PEH）。间歇运动（IE）也会导致 PEH。目的：本系统评价和荟萃分析旨在比较 CE 和 IE 对成年人 PEH 程度的影响。方法：检索了截至 2020 年 3 月在 PubMed、Web of Knowledge、Scopus 和 CENTRAL 数据库中发表的期刊中的研究，比较了 CE 和 IE 之间 PEH 的程度。PEH 定义为运动后 45-60 分钟。采用随机效应模型分析两组间血压差异。数据以加权均数差（WMD）和 95%置信区间（CI）表示。p 值<0.05 为统计学意义。采用 TESTEX 量表（0-15）评估研究的方法学质量。结果：IE 在收缩压（WMD：-2.93mmHg [95%CI：-4.96，-0.90]，p=0.005，I2=50%）和舒张压（WMD：-1.73mmHg [95%CI：2.94，-0.51]，p=0.005，I2=0%）上比 CE 有更大的 PEH 幅度（12 项研究，196 名参与者）。TESTEX 量表上的研究评分从 10 到 11 分不等。结论：与 CE 相比，IE 在运动后 45-60 分钟时会导致更大幅度的 PEH。IE 和 CE 研究中缺乏运动期间的不良事件数据，使得无法比较这些策略的安全性。
