Efeitos agudos do exercício aeróbico com restrição de fluxo sanguíneo sobre a pressão arterial: uma revisão sistemática

Introduction: The acute effects of aerobic exercise with blood flow restriction (AE+BFR) on systolic, diastolic, and mean blood pressure remain scarce and inconsistent in the literature. Objective: To systematically review the acute effects of AE+BFR on systolic (SBP), diastolic (DBP), and mean blood pressure (MBP) in adults and older adults. Methods: Searches were conducted in October 2025 in PubMed, EMBASE, Cochrane Library, LILACS, Scopus, and gray literature. Randomized controlled trials comparing the acute effects of a single session of AE+BFR with conventional aerobic exercise (AE-C) on blood pressure were included. Two independent reviewers performed study selection, data extraction, and assessment of risk of bias (RoB 2) and certainty of evidence (GRADE). Results: Eight studies, totaling 130 participants, were included. The qualitative synthesis indicated that seven studies found no differences in SBP, DBP, or MBP after AE+BFR compared with AE-C. One study reported an increase in DBP immediately after AE+BFR (79.23 ± 10.56 vs. 69.69 ± 8.79 mmHg; p = 0.001). All studies showed some concerns regarding risk of bias, and the certainty of evidence was rated as very low for all three outcomes. Conclusions: Most studies indicate that AE+BFR does not acutely change SBP, DBP, or MBP compared with conventional aerobic exercise. However, the small number of studies, heterogeneity of protocols, and very low certainty of evidence suggest that the findings should be interpreted with caution.
