Executive function will gradually decline with the increase of age, which will have a negative impact on the quality of life and general health. Exercise intervention can improve executive function and prevent its deterioration, but the evidence from randomized controlled trials is not consistent.
To assess the effect of exercise intervention on executive function of healthy middle-aged and elderly people, and briefly describe its mechanism.
A search was conducted using PubMed, Web of science and EBSCO. The searches were limited to English articles published from January 2010 to January 2022. The information is extracted from searched articles included or excluded based on certain criteria.
The search returned 2,746 records, of which 11 articles were included in the systematic review, and 8 articles were supplemented according to the references included and related reviews. The results show that different types of exercise intervention have positive effects on the executive function of the middle-aged and elderly people. The intervention prescriptions in most studies are executed in medium to low frequency, medium intensity and medium duration, while only 11% of the studies were followed up.
The intervention, which was executed twice a week with 30-60 min single intervention time and over 12 weeks total duration, showed a good intervention effect. Exercise intervention is to improve executive function by affecting the activation of brain network and the synthesis of neurotransmitters.
执行功能会随着年龄的增长而逐渐衰退，这会对生活质量和总体健康产生负面影响。运动干预可以改善执行功能并防止其恶化，但随机对照试验的证据并不一致。
评估运动干预对健康中老年人执行功能的影响，并简要描述其机制。
使用PubMed、科学网和EBSCO进行检索。检索限于2010年1月至2022年1月发表的英文文章。根据特定标准从检索到的文章中提取纳入或排除的信息。
检索返回2746条记录，其中11篇文章纳入系统评价，根据纳入的参考文献和相关综述补充8篇文章。结果表明，不同类型的运动干预对中老年人的执行功能有积极影响。大多数研究中的干预方案以中低频、中等强度和中等时长执行，而只有11%的研究进行了随访。
每周进行两次干预，单次干预时间为30 - 60分钟，总时长超过12周，显示出良好的干预效果。运动干预通过影响脑网络激活和神经递质合成来改善执行功能。
