The global aging population has led to a public health crisis, with cardiovascular disease, hypertension, arterial stiffness, and obesity becoming major concerns. Resistance training (RT) has been shown to improve cardiovascular health, but traditional RT has certain limitations.
The present systematic review and meta-analysis aims to assess the effects of circuit-based resistance training (CBRT) on blood pressure, arterial stiffness as well as body composition in community-dwelling older adults. PubMed, Cochrane library, Embase, Scopus, and Web of Science, five databases in total, were searched until January 2025. The analysis was restricted to randomized controlled trials.
A total of 14 studies, involving 704 participants, were included in the meta-analysis. The primary outcomes assessed were arterial stiffness, blood pressure, and body composition.
Significant intervention effects were identified in 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), brachial-ankle pulse wave velocity (WMD = -101.81 cm/s, 95% CI: -136.92 to -66.70), percentage of body fat (WMD = -3.21%, 95% CI: -4.20 to -2.22), fat mass (WMD = -4.83 kg, 95% CI: -8.80 to -0.86), 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 by training frequency showed that participants with high training frequency (>3 sessions/week) reduce systolic blood pressure more significantly compared to moderate to low training frequency (≤2 sessions/week) while diastolic blood pressure show no difference between subgroups.
CBRT interventions improve blood pressure, arterial stiffness, and body composition in community-dwelling older adults significantly. Additionally, three sessions of CBRT per week show a superior systolic blood pressure lowering effect.

全球人口老龄化引发了一场公共卫生危机，心血管疾病、高血压、动脉僵硬度和肥胖成为主要关注点。抗阻训练（RT）已被证明可改善心血管健康，但传统抗阻训练存在一定局限性。
本系统评价和荟萃分析旨在评估社区居住的老年人进行循环抗阻训练（CBRT）对血压、动脉僵硬度以及身体成分的影响。截至2025年1月，共检索了五个数据库，即PubMed、Cochrane图书馆、Embase、Scopus和Web of Science。分析仅限于随机对照试验。
共有14项研究、704名参与者纳入荟萃分析。评估的主要结局为动脉僵硬度、血压和身体成分。
在收缩压（加权均数差[WMD]=-6.10 mmHg，95%置信区间[CI]：-8.07至-4.12）、舒张压（WMD=-2.88 mmHg，95%CI：-3.96至-1.81）、臂踝脉搏波速度（WMD=-101.81 cm/s，95%CI：-136.92至-66.70）、体脂百分比（WMD=-3.21%，95%CI：-4.20至-2.22）、脂肪量（WMD=-4.83 kg，95%CI：-8.80至-0.86）、去脂体重（WMD=1.36 kg，95%CI：0.83 - 1.89）和股骨颈骨矿物质含量（WMD=0.27 g，95%CI：0.14至0.39）方面发现了显著的干预效果。按训练频率进行的亚组分析显示，与中低训练频率（≤2次/周）相比，高训练频率（>3次/周）的参与者收缩压降低更显著，而舒张压在亚组间无差异。
CBRT干预可显著改善社区居住老年人的血压、动脉僵硬度和身体成分。此外，每周进行三次CBRT显示出更优的降低收缩压效果。
