This overview aims to summarize the effectiveness of cognitive-motor dual-task and exergame interventions on cognitive, physical and dual-task functions in healthy older adults, as well as the feasibility, safety, adherence, transfer and retention of benefits of these interventions. We searched for systematic reviews or meta-analyses assessing the effects of cognitive-motor dual-task and exergame interventions on cognitive, physical and dual-task functions in cognitively healthy older adults through eight databases (CDSR (Cochrane), MEDLINE (PubMed), Scopus, EMBASE, CINAHL, PsycINFO, ProQuest and SportDiscus). Two reviewers performed the selection, data extraction and risk of bias evaluation independently (PROSPERO ID: CRD42019143185). Eighteen reviews were included in this overview. Overall, positive effects of cognitive-motor dual-task interventions on cognitive, physical and dual-task functions, as well as exergames on cognitive functions only, were observed in cognitively healthy older adults. In contrast, the effects of exergames on physical functions are more controversial, and their effects on dual-task functions have not been studied. The feasibility, safety, adherence, transfer and retention of benefits for both intervention types are still unclear. Future studies should follow more rigorous methodological standards in order to improve the quality of evidence and provide guidelines for the use of cognitive-motor dual-task and exergame interventions in older adults.

本概述旨在总结认知运动双重任务和运动游戏干预对健康老年人的认知、身体和双重任务功能的有效性，以及这些干预措施的可行性、安全性、依从性、转移和保留益处。我们通过八个数据库（CDSR (Cochrane)、MEDLINE (PubMed)、 Scopus、EMBASE、CINAHL、PsycINFO、ProQuest 和 SportDiscus）。两名审稿人独立进行了选择、数据提取和偏倚风险评估（PROSPERO ID：CRD42019143185）。此概述中包含 18 条评论。全面的，在认知健康的老年人中观察到认知运动双任务干预对认知、身体和双任务功能的积极影响，以及仅对认知功能的运动游戏。相比之下，exergames 对身体功能的影响更具争议性，其对双重任务功能的影响尚未得到研究。两种干预类型的可行性、安全性、依从性、转移和收益保留仍不清楚。未来的研究应遵循更严格的方法学标准，以提高证据质量，并为老年人使用认知-运动双重任务和运动游戏干预提供指南。exergames 对身体功能的影响更具争议性，并且尚未研究其对双重任务功能的影响。两种干预类型的可行性、安全性、依从性、转移和收益保留仍不清楚。未来的研究应遵循更严格的方法学标准，以提高证据质量，并为老年人使用认知-运动双重任务和运动游戏干预提供指南。exergames 对身体功能的影响更具争议性，并且尚未研究其对双重任务功能的影响。两种干预类型的可行性、安全性、依从性、转移和收益保留仍不清楚。未来的研究应遵循更严格的方法学标准，以提高证据质量，并为老年人使用认知-运动双重任务和运动游戏干预提供指南。
