Abstract

Objective: To assess the effect of exercise training as a single intervention (ie, Exercise-Only) and exercise combined with other lifestyle interventions (ie, Exercise-Plus) on executive functions, memory and processing speed of older adults living without dementia.

Design: We performed a systematic review with pairwise meta-analyses and network meta-analysis to examine the effects of: (1) Exercise-Only versus Control; (2) Exercise-Plus versus Control; and (3) Exercise-Plus versus Exercise-Only.

Data sources: We searched four databases (Medline, Embase, PsycINFO and CINAHL) between database inception and March 2026.

Eligibility criteria: We included randomised controlled trials that examined the effects of exercise training as a single domain or multidomain intervention on cognitive function of adults aged over 60 living without dementia.

Results: We included 227 studies in the pairwise meta-analyses (Exercise-Only=178, Exercise-Plus=67) and 105 studies in the subset for the network meta-analysis (Exercise-Only=76, Exercise-Plus=36). Cognitive training and cognitively engaging activities were the most common Plus component in the included studies. Exercise-Only produced statistically significant improvements across all three cognitive domains compared with Control. Exercise-Plus was only significantly better than Control for memory. Exercise-Plus was also significantly better than Exercise-Only for executive functions and processing speed but not for memory.

Conclusion: We recommend the promotion of exercise training to improve cognitive outcomes of older adults. Further research is needed to determine the added benefit of multidomain exercise interventions.

仅运动干预和基于运动的多领域生活方式干预促进无痴呆老年人认知功能:一项系统综述和荟萃分析
目的:评估运动训练作为单一干预(即运动- only)和运动结合其他生活方式干预(即运动- plus)对无痴呆老年人执行功能、记忆和处理速度的影响。设计:我们采用两两荟萃分析和网络荟萃分析进行了系统回顾,以检验:(1)纯运动与对照组的影响;(2)运动+与控制;(3)运动+与运动+。数据来源:从数据库建立到2026年3月,我们检索了四个数据库(Medline, Embase, PsycINFO和CINAHL)。入选标准:我们纳入了随机对照试验,这些试验检验了运动训练作为单领域或多领域干预对60岁以上无痴呆成年人认知功能的影响。结果:我们在两两荟萃分析中纳入了227项研究(Exercise-Only=178, Exercise-Plus=67),在网络荟萃分析中纳入了105项研究(Exercise-Only=76, Exercise-Plus=36)。在纳入的研究中,认知训练和认知参与活动是最常见的Plus成分。与对照组相比,单纯运动在所有三个认知领域都产生了统计学上显著的改善。在记忆力方面,运动加组只明显好于对照组。在执行功能和处理速度方面,Exercise-Plus也明显优于Exercise-Only,但在记忆方面则不然。结论:我们建议促进运动训练以改善老年人的认知结果。需要进一步的研究来确定多领域运动干预的额外益处。普洛斯彼罗注册号:CRD42022322199。

期刊介绍: The British Journal of Sports Medicine (BJSM) is a dynamic platform that presents groundbreaking research, thought-provoking reviews, and meaningful discussions on sport and exercise medicine. Our focus encompasses various clinically-relevant aspects such as physiotherapy, physical therapy, and rehabilitation. With an aim to foster innovation, education, and knowledge translation, we strive to bridge the gap between research and practical implementation in the field. Our multi-media approach, including web, print, video, and audio resources, along with our active presence on social media, connects a global community of healthcare professionals dedicated to treating active individuals.
