Why the study?

Resistance training improves cardiovascular health, but traditional resistance training has limitations, warranting an assessment of the effects of circuit-based resistance training on blood pressure, arterial stiffness, and body composition in community-dwelling older adults.

Does circuit-based resistance training improve blood pressure, arterial stiffness, and body composition in community-dwelling older adults?

Key Points

To assess the effects of circuit-based resistance training on blood pressure, arterial stiffness, and body composition in community-dwelling older adults.
Systematic review and meta-analysis of randomized controlled trials searched across five databases (PubMed, Cochrane Library, Embase, Scopus, Web of Science) through January 2025 (PROSPERO CRD42025646360).
Included 14 randomized controlled trials comprising a total of 704 community-dwelling older adults.
Circuit training significantly reduced systolic blood pressure (WMD = -6.10 mmHg, 95% CI: -8.07 to -4.12), diastolic blood pressure (WMD = -2.88 mmHg, 95% CI: -3.96 to -1.81), and arterial stiffness assessed by brachial-ankle pulse wave velocity (WMD = -101.81 cm/s, 95% CI: -136.92 to -66.70).
Interventions produced significant improvements in body composition, reducing body fat percentage (WMD = -3.21%, 95% CI: -4.20 to -2.22) and fat mass (WMD = -4.83 kg, 95% CI: -8.80 to -0.86) while increasing lean body mass (WMD = 1.36 kg, 95% CI: 0.83-1.89) and femoral neck bone mineral content (WMD = 0.27 g, 95% CI: 0.14-0.39).
Subgroup analysis indicated that higher training frequencies (>3 sessions/week) led to significantly greater systolic blood pressure reductions compared to lower frequencies (≤2 sessions/week), with no subgroup differences observed for diastolic blood pressure.
