Physical exercise, particularly resistance training (RT), is proven treatment to reduce the accelerated decline in muscle strength exhibited by older adults, but its effect is hindered by low adherence rate, even under well-structured programs.
We investigated the efficacy of circuit resistance training (CRT) on muscle strength, lean mass and aerobic capacity in older adults based on report in MEDLINE, EMBASE, ClinicalTrials.gov and Cochrane electronic (through 8/2016).
middle and older aged men and/or women who followed a structured program, assigned to CRT.
Out of 237 originally identified articles, 10 articles were included with a total of 362 patients with mean: age -64.5±7.4 years; 3±1.15 sessions/week; session duration 41.8±15.9min.
Upper body strength modestly increased, by 1.14kg (95% CI; 0.28-2.00), whereas larger increment was seen in lower body strength (11.99; 2.92-21.06). Higher program volume (>24 sessions) positively influenced upper body strength and aerobic capacity.
(1) variability in the studies' validity; (2) relatively low number of studies.
CRT is a valid alternative to conventional RT. Its shorter duration and lower intensity relative to traditional RT, may increase adherence to training in older adults.
体育锻炼，特别是抗阻训练（RT），已被证实是一种治疗方法，可以减少老年人肌肉力量的加速下降，但即使在结构良好的方案下，其效果也受到低依从率的阻碍。
我们基于 MEDLINE、EMBASE、ClinicalTrials.gov 和 Cochrane 电子数据库（截至 2016 年 8 月）的报告，研究了循环抗阻训练（CRT）对老年人肌肉力量、瘦体重和有氧能力的疗效。
接受过结构化方案、被分配到 CRT 的中老年男性和/或女性。
在最初确定的 237 篇文章中，有 10 篇文章被纳入，共纳入 362 名患者，平均年龄为 64.5±7.4 岁；每周 3±1.15 次；每次持续时间 41.8±15.9 分钟。
上肢力量适度增加 1.14kg（95%置信区间；0.28-2.00），而下肢力量增加更大（11.99；2.92-21.06）。更高的方案量（>24 次）对上肢力量和有氧能力有积极影响。
（1）研究有效性的变异性；（2）研究数量相对较少。
CRT 是传统 RT 的有效替代方法。与传统 RT 相比，其持续时间更短，强度更低，可能会增加老年人对训练的依从性。
