Abstract

Purpose

To analyze the effect of complex exercise on cognitive ability of the elderly.

Study Design

By means of literature screening and quality assessment, high-quality studies were extracted to comprehensively analyze the effects of complex exercise on cognitive ability of the elderly.

Method

By searching databases such as Web of Science and CNKI, we integrated experimental studies on the effects of complex exercise on cognitive ability in the elderly, conducted literature quality assessment according to Cochrane bias risk assessment tool, and conducted meta-analysis using Review Manager 5.3.

Results

1) A total of 27 articles of high quality literature were included, containing 1072 subjects; 2) Complex exercise had a positive effect on cognitive abilities of older adults (SMD = 0.56; 95 % CI: 0.34, 0.78, P < 0.00001), with differences in the effects on different cognitive abilities, with the best effect on cognitive inhibition (SMD = 0.79; 95 % CI: 0.17, 1.41, P = 0.01), followed by executive function (SMD = 0.76; 95 % CI: 0.41, 1.11, P < 0.0001) and cognitive speed (SMD = 0.48; 95 % CI: 0.13, 0.84, P = 0.008), and a non-significant effect of memory intervention (SMD = 0.07; 95 % CI: -0.2, 0.33, P = 0.62); 3) The literature publication bias detection was more effective.

Conclusion

1) Complex exercise had a moderate effect in promoting cognitive performance in older adults. 2) By subgroup analysis, the order of intervention effect was cognitive inhibition, executive function, and cognitive speed, in descending order. 3) The intervention effect of complex exercise on memory in older adults was not significant.

复杂运动干预对老年人认知表现的meta分析研究。

目的：分析复杂运动对老年人认知能力的影响。研究设计：采用文献筛选和质量评价的方法，提取高质量的研究，综合分析复杂运动对老年人认知能力的影响。方法：检索Web of Science、CNKI等数据库，整合复杂运动对老年人认知能力影响的实验研究，采用Cochrane偏倚风险评估工具进行文献质量评价，采用Review Manager 5.3进行meta分析。结果：1)共纳入优质文献27篇，受试者1072人；2)复杂运动对老年人认知能力有正向影响(SMD = 0.56；95% CI: 0.34, 0.78, P < 0.00001)，对不同认知能力的影响存在差异，其中对认知抑制效果最好(SMD = 0.79；95% CI: 0.17, 1.41, P = 0.01)，其次是执行功能(SMD = 0.76；95% CI: 0.41, 1.11, P < 0.0001)和认知速度(SMD = 0.48；95% CI: 0.13, 0.84, P = 0.008)，记忆干预无显著影响(SMD = 0.07；95% ci: -0.2, 0.33, p = 0.62)；3)文献发表偏倚检测更有效。结论：1)复杂运动对老年人认知能力的促进作用中等。2)经亚组分析，干预效果由大到小依次为认知抑制、执行功能、认知速度。3)复杂运动对老年人记忆的干预作用不显著。

期刊介绍： Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published. Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.
