摘　　要：目的系统评价抗阻运动干预与老年人下肢肌肉力量及功能提升的剂量-效应关系。方法计算机检索EBSCO、PubMed、Web of Science、CNKI、VIP和WanFang Data数据库,搜集关于抗阻运动对老年人下肢肌肉力量及功能影响的随机对照试验(RCT),检索时限均从建库至2022年7月。由2名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后,采用RevMan 5.4和Stata 15.0软件进行网状Meta分析。结果共纳入32个RCT,总样本量1594人。网状Meta分析结果显示,强度50%~70%1RM、周期8~12周、频率3~4次/周、时间30~45分钟、间歇1.1~2分钟的抗阻运动干预效果最佳。结论抗阻运动改善老年人下肢肌肉力量及功能的最佳选择为中等运动强度(50%~70%1RM)、持续8~12周、每周运动3~4次、每次运动时间30~45分钟、组间间歇1.1~2分钟。Objective To systematically review the dose-effect relationship between resistance exercise intervention and lower extremity muscle strength and function enhancement in the aging.Methods EBSCO,PubMed,Web of Science,CNKI,VIP,and WanFang Data databases were electronically searched to collect randomized controlled trials(RCTs)on the effects of resistance exercise on muscle strength and function of the lower extremities in older adults from inception to July 2022.Two reviewers independently screened literature,extracted data and assessed the risk of bias of the included studies.A network meta-analysis was then performed by using RevMan 5.4 and Stata 15.0 software.Results A total of 32 RCTs with a total sample size of 1594 individuals were included.The results of network metaanalysis showed that the elements of resistance exercise prescription:intensity 50%-70%1RM,period 8-12 weeks,frequency 3-4 times/week,duration 30-45 min,and intervals 1.1-2 min were superior to other doses.Conclusion The optimal dose of resistance exercise for improving lower extremity muscle strength and function in older adults is moderate exercise intensity(50%-70%1RM)for 8-12 weeks,3-4 times per week,30-45 min per exercise,and 1.1-2 min interval between sets.
