体育活动对老年人的执行功能（EF）是有益的，但当他们认知脆弱时，如在抑郁发作期间，可能特别保护EF。干预研究支持体育活动对临床抑郁老年人EF的更有效影响，尽管这些结果可能对健康社区老年人的日常情绪和体育活动具有有限的推广作用。目前的研究旨在测试老年人在轻度抑郁症状升高引起的认知脆弱性期间，身体活动是否更能保护EF。每半年收集150名总体健康的社区老年人的纵向数据，并用多层次模型进行分析。在抑郁症状相对加重的时期，体育活动对EF的保护作用更大。在认知脆弱期，身体活动对EF的保护作用可能扩展到社区居住的非临床抑郁症状水平的老年人。
Physical activity is beneficial for the executive functioning (EF) of older adults, but may be particularly protective of EF when they are cognitively vulnerable, such as during depressive episodes. Intervention studies support more potent effects of physical activity on EF among clinically depressed older adults, though these results may have limited generalizability to the daily mood and physical activity of healthy, community dwelling older adults. The current study aimed to test whether physical activity among older adults was more protective of EF during periods of cognitive vulnerability due to mildly elevated depressive symptoms. Longitudinal data from 150 generally healthy, community dwelling older adults were collected semi-annually and analyzed with multilevel modeling. Physical activity was more protective of EF within individuals during periods of relatively elevated depressive symptoms. The power of physical activity to protect EF during periods of cognitive vulnerability may extend to community dwelling older adults with non-clinical levels of depressive symptoms.
