【摘要】 目的 探讨弹性抗阻运动对老年人肌肉力量和躯体功能的影响。方法 选取Cochrane library、Medline、Web of Science、Embase、CINAHL等数据库从建库至2022年1月发表的探讨弹性抗阻运动对老年人肌肉力量和（或）躯体功能改善效果的英文RCT研究。对所有文献进行整理和分析，并使用Cochrane handbook(5.1.0)质量评价标准对文献进行质量评估，分析弹性抗阻运动对老年人握力、椅立试验（timed chair rise test, TCR）、步速（gait speed, GS）、起立-行走计时测试（timed up and go test, TUG）的影响。结果 共检索文献612篇，最终纳入有效文献9篇，共涉及研究对象544例，其中7篇文献质量为A级、2篇文献质量为B级。Meta分析结果显示，弹性抗阻运动可以改善老年人的握力（MD=-1.48,95%CI:-2.07～-0.88,P=0.19,I~2=30%）、TCR成绩（MD=-2.05,95%CI:-2.62～-1.47,P=0.17,I~2=37%）和TUG成绩（MD=-1.91,95%CI:-2.32～-1.50,P=0.63,I~2=0%），可能提高老年人的GS(MD=-0.03,95%CI:-0.10～0.02,P=0.05,I~2=56%)。结论 弹性抗阻运动可以有效改善老年人的握力和躯体功能。更多还原

【Abstract】 Objective To explore the effect of elastic resistance exercise on muscle strength and physical function of the elderly. Methods The English RCT studies on the improvement of muscle strength and/or physical function of elastic resistance exercise of the elderly from establishment to January 2022 were selected from Cochrane library, Medline, Web of Science, Embase and CINAHL databases. All the literatures were sorted out and analyzed, and were evaluated by Cochrane handbook(5.1.0) quality evaluation standard, and the influence of elastic resistance exercise on grip strength, timed chair rise test(TCR), gait speed(GS) and timed up and go test(TUG) of the elderly were analyzed. Results A total of 612 literatures were retrieved, and nine valid articles were finally included, involving 544 subjects, of which seven articles were of Grade A and two were of Grade B. Meta-analysis showed that elastic resistance exercise improved the grip strength(MD =-1.48,95%CI :-2.07--0.88, P = 0.19, I~2 = 30%), TCR score(MD =-2.05, 95%CI:-2.62--1.47, P = 0.17, I~2 = 37%) and TUG scores(MD =-1.91, 95%CI:-2.32--1.50, P = 0.63, I~2 = 0%) of the elderly, and might increase the GS(MD =-0.03,95%CI:-0.10-0.02, P = 0.05, I~2 = 56%) of the elderly. Conclusions Elastic resistance exercise can effectively improve the grip strength and physical function of the elderly.更多还原
