Abstract：
OBJECTIVE: Provide a synthesis of the current literature about the effects of detraining on cognitive functions in older adults.
METHODS: The PICOS acronym strategy was performed in PubMed/MEDLINE, Web of Science, Cochrane Library and PsycINFO database. The Preferred Reporting Items for Systematic Review and Meta-Analyses statement had been followed in the present study, in which the search was conducted on October 2023. The study selection consisted in original articles including older adults, detraining after training exercise period, use of tests or scales to measure cognitive function. The Downs and Black checklist had been used to assess the studies quality. Sample characteristics, type of previous training, detraining period, cognitive functions measurements and main results were extracted by 2 investigators.
RESULTS: From 1927 studies, 12 studies were included, being 11 studies identified via systematic research, and 1 study by citation search. Older adults, ranged from 60 to 87 years old, were assessed after detraining. The cognitive functions most evaluated were global cognition and executive functions. One study evaluated both cognitive outcome and cerebral blood flow. Most of the studies demonstrated a decline in the cognitive function after detraining.
CONCLUSIONS: Exercise detraining period, ranging from 10 days to 16 weeks, can effect negatively the cognitive function in older adults.

摘要：
目的：提供有关去训练对老年人认知功能影响的现有文献的综合。
方法：PICOS首字母缩写词策略在PubMed/MEDLINE中进行，WebofScience,Cochrane图书馆和PsycINFO数据库。本研究遵循了系统评价和荟萃分析声明的首选报告项目，其中搜索于2023年10月进行。研究选择包括原始文章，包括老年人，训练锻炼期结束后的去训练，使用测试或量表来测量认知功能。Downs和Black检查表已用于评估研究质量。样品特征,以前的培训类型，去训练期，2名研究者提取了认知功能测量值和主要结果.
结果：从1927年的研究，包括12项研究，是通过系统研究确定的11项研究，和1项通过引文搜索进行的研究。老年人,年龄从60岁到87岁，在去训练后进行评估。评估最多的认知功能是整体认知和执行功能。一项研究评估了认知结果和脑血流量。大多数研究表明，训练后认知功能下降。
结论：运动训练期，从10天到16周，会对老年人的认知功能产生负面影响。
