Dynamic resistance training significantly reduces resting blood pressure in populations with varying baseline levels

ObjectiveThis study aimed to systematically evaluate the effects of dynamic resistance training (DRT) on populations with varying baseline blood pressure (BP) levels, compare the commonalities and differences across subgroups, and explore potential sources of heterogeneity.MethodsA systematic literature search of databases including PubMed, Embase, the Cochrane Library, and Web of Science was conducted from inception to January 2026. Randomized controlled trials (RCTs) investigating DRT as the intervention and resting BP as the outcome were included. A random-effects model was employed to calculate the pooled mean differences (MDs) and 95% confidence intervals (CIs). Subgroup analyses were performed based on baseline BP classifications and antihypertensive medication status, while meta-regression was used to assess the moderating effect of age. The Risk of Bias 2 (RoB 2) tool was used to assess the risk of bias, and the certainty of evidence was evaluated using the GRADE approach.ResultsEighteen studies were ultimately included in this meta-analysis. For systolic blood pressure (SBP), 18 studies comprising 27 effect sizes and 328 participants were pooled, revealing a significant reduction following DRT (MD = −7.57 mmHg; 95% CI: [−9.40, −5.74]; p
