(1) Background: High-Intensity Functional Training (HIFT) is a new exercise modality that emphasizes multi-joint functional movements adaptable to any fitness level and promotes greater muscle recruitment. Previous studies have evaluated the positive effects of HIFT on mental and cognitive health but have not evaluated it in older people. This study aims to conduct a systematic review of randomized controlled trials assessing the effects of HIFT on general cognition in older adults with cognitive impairment. (2) Methods: Following the PRISMA 2020 guideline, articles that did a high-intensity functional physical exercise intervention on cognitive performance in older adults with mild to moderate cognitive impairment (MMSE > 10) or dementia, aged 55 years or older, published between 2011 and 2021 in five different electronic databases: PubMed, Web of Science, Scopus, CINAHL, and Cochrane plus were included. (3) Results: 7 articles were included, all having general cognition as their primary outcome. All assessed general cognition using the Mini-Mental State Examination, the ADAS-Cog, or both. All studies had at least one HIFT experimental group with a frequency of 2 sessions per week and a variable duration between protocols of 12, 13, 16, and 26 weeks. Two articles showed that a progressive HIFT program improves general cognition, four articles showed no significant changes within or between groups and one article concluded that a HIFT intervention does not slow cognitive decline. (4) Conclusions: Evidence exists of the benefits of HIFT on general cognition in older adults with cognitive impairment, assessed using the MMSE, the ADAS-cog, or both. Two articles that showed improvement in cognitive function used progressive HIFT with 80% RM at 6, 12, and 1 weeks; however, in the other articles, due to the heterogeneity of intervention protocols, measurement time points, and control group activities, mixed results were evidenced
(1) 背景：高强度功能训练（HIFT）是一种新的运动方式，强调多关节功能运动，适用于任何健身水平，并能促进更多肌肉参与。以往研究评估了HIFT对心理和认知健康的积极影响，但未在老年人中进行评估。本研究旨在对评估HIFT对认知障碍老年人一般认知影响的随机对照试验进行系统评价。(2) 方法：遵循PRISMA 2020指南，纳入2011年至2021年间在五个不同电子数据库（PubMed、Web of Science、Scopus、CINAHL和Cochrane plus）中发表的、对55岁及以上轻度至中度认知障碍（MMSE>10）或痴呆的老年人认知表现进行高强度功能性体育锻炼干预的文章。(3) 结果：纳入7篇文章，均以一般认知作为主要结局。所有研究均使用简易精神状态检查表、阿尔茨海默病协作研究认知量表或两者来评估一般认知。所有研究至少有一个HIFT实验组，每周训练2次，各方案的持续时间在12、13、16和26周之间不等。两篇文章表明，渐进式HIFT方案可改善一般认知，四篇文章表明组内或组间无显著变化，一篇文章得出结论认为HIFT干预不会减缓认知衰退。(4) 结论：有证据表明，使用MMSE、ADAS-cog或两者评估时，HIFT对认知障碍老年人的一般认知有益。两篇显示认知功能改善的文章使用了渐进式HIFT，在第6、12和1周时负荷为80%1RM；然而，在其他文章中，由于干预方案、测量时间点和对照组活动的异质性，结果不一。
