Abstract：
OBJECTIVE: To comprehensively synthesise existing evidence from systematic reviews regarding the effects of exercise interventions on physical, psychological and social outcomes in frail older adults to provide reference for clinical practice.
BACKGROUND: Frailty is highly prevalent in older adults and associated with increased adverse health outcomes. Some systematic reviews have assessed the effectiveness of exercise interventions in frail older adults with varied inclusion criteria, methodology quality, types of exercise and outcome measures.
METHODS: An overview of systematic reviews reported following the PRISMA checklist.
METHODS: PubMed, Embase, CINAHL, Web of Science and Cochrane database were searched from inception until June 2023 to identify relevant systematic reviews with or without meta-analysis of randomised controlled trails. Two reviewers independently selected articles, extracted data, assessed quality and summarised findings.
RESULTS: A total of 17 systematic reviews were included, with methodology quality varying from moderate to critically low. The most frequent types of exercise were multicomponent exercise and resistance-based exercise in community and long-term care facilities, respectively. Exercise interventions had positive effects on most physical outcomes and depression, but inconsistent effects on cognitive function and quality of life. The quality of the evidence for most outcomes was low and very low.
CONCLUSIONS: This overview highlights the importance of exercise interventions to improve physical, psychological and social aspects in frail older adults and provides evidence on characteristics of exercise interventions for frailty in various settings.
CONCLUSIONS: Multicomponent exercise and resistance-based exercise should be recommended for frail older adults. There is a need of more well-designed research with large sample size and validated definition of frailty. Long-term effects, adherence during and after exercise interventions, adverse events and cost-effectiveness should be emphasised in future studies.
UNASSIGNED: The overview protocol was registered on the International Prospective Register of Systematic reviews (CRD 42021281327).
UNASSIGNED: No patient or public contribution.
UNASSIGNED: The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were applied to report the results.

摘要：
目的：全面综合现有的关于运动干预对身体影响的系统评价证据，体弱老年人的心理和社会结果为临床实践提供参考。
背景：虚弱在老年人中非常普遍，并且与不良健康结局增加有关。一些系统评价评估了不同纳入标准的体弱老年人运动干预的有效性。方法论质量，锻炼类型和结果测量。
方法：根据PRISMA检查表报告的系统综述。
方法：PubMed，Embase,CINAHL,从开始到2023年6月搜索WebofScience和Cochrane数据库，以识别有或没有随机对照研究的荟萃分析的相关系统评价。两名审稿人独立选择文章，提取的数据，评估质量和总结结果。
结果：共纳入17篇系统综述，方法学质量从中等到极低不等。最常见的运动类型是在社区和长期护理机构中的多组分运动和基于阻力的运动，分别。运动干预对大多数身体结果和抑郁有积极影响，但对认知功能和生活质量的影响不一致。大多数结果的证据质量很低，而且非常低。
结论：本概述强调了运动干预对改善身体，脆弱的老年人的心理和社会方面，并提供了各种情况下针对虚弱的运动干预措施的特征的证据。
结论：对于体弱的老年人，应该推荐多分量运动和基于阻力的运动。需要更精心设计的研究，样本量大，对脆弱的定义经过验证。长期影响,运动干预期间和之后的依从性，在未来的研究中应强调不良事件和成本效益.
■概述方案已在国际前瞻性系统评价登记册（CRD42021281327）上注册。
■没有患者或公众捐款。
■应用系统评价和荟萃分析（PRISMA）指南的首选报告项目报告结果。
