The goal of the present meta-analysis was to address studies that examined the relationship between walking as one of the most prevalent types of leisure-time activity and executive function being a higher-order cognitive function essential for independent functioning.
The following data sources were used: English-language publications in PubMed, EMBASE, PsycINFO, Cinahl, and Cochrane; the last search took place in January 2012. From these data sources, only randomized controlled trials including older people with (N = 3) and without (N = 5) cognitive impairment were selected.
Walking has been shown to improve set-shifting and inhibition in sedentary older persons without cognitive impairment (d = 0.36; 95% confidence interval: 0.16-0.55; z = 3.56; p <0.0001). In older persons with cognitive impairment, walking did not show improvements in executive functioning (d = 0.14; 95% confidence interval: -0.36-0.64; z = 0.35; p = 0.56).
This finding is clinically relevant because participation in a walking program may prevent or postpone a (further) decline in executive function in those who are sedentary.
本荟萃分析旨在研究作为最常见的休闲活动之一的散步与执行功能（一种对独立功能至关重要的高级认知功能）之间的关系。
使用了以下数据源：PubMed、EMBASE、PsycINFO、Cinahl 和 Cochrane 中的英文出版物；最后一次搜索于 2012 年 1 月进行。从这些数据源中，仅选择了包括有（N=3）和没有（N=5）认知障碍的老年人的随机对照试验。
散步已被证明可以改善无认知障碍的久坐老年人的定势转移和抑制能力（d=0.36；95%置信区间：0.16-0.55；z=3.56；p<0.0001）。在有认知障碍的老年人中，散步并没有改善执行功能（d=0.14；95%置信区间：-0.36-0.64；z=0.35；p=0.56）。
这一发现具有临床意义，因为参加散步计划可能有助于预防或延缓久坐不动的老年人执行功能的（进一步）下降。
