To analyze studies that investigated the association between physical activity assessed by accelerometry and cognitive function in older people.
A systematic review was carried out in four electronic databases (PubMed, Web of Science, Scopus, and SportsDiscus).
In total, 195 records were identified. Fifty-two studies were selected for a full evaluation; 23 were selected according to the inclusion criteria adopted and divided into four chapters (characteristics of the studies, the association between physical activity level and cognitive function decline, effects of physical activity in reducing the chances of cognitive function decline and effects of physical activity on brain plasticity. The cross-sectional studies had an average score of 7 points, and the cohort studies obtained 10 points, indicating the high quality of the selected studies. Seven studies indicated an association between Moderate to vigorous physical activities (MVPA) and cognitive function, two specifically indicated a reduction in the chances of cognitive function decline according to the interquartile of MVPA, and three studies indicated improvements in MVPA in brain plasticity.
Measured by accelerometry, seems to be favorably associated with important outcomes in cognitive function assessed through questionnaires, imaging analyses, and biochemical markers with older adults.
分析通过加速度计评估的身体活动与老年人认知功能之间关联的研究。
在四个电子数据库（PubMed、科学网、Scopus和SportsDiscus）中进行了系统综述。
总共识别出195条记录。选择了52项研究进行全面评估；根据所采用的纳入标准选择了23项研究，并分为四章（研究特征、身体活动水平与认知功能下降之间的关联、身体活动在降低认知功能下降几率方面的作用以及身体活动对脑可塑性的影响）。横断面研究的平均得分为7分，队列研究得10分，表明所选研究质量较高。七项研究表明中度至剧烈身体活动（MVPA）与认知功能之间存在关联，两项研究特别指出根据MVPA的四分位数间距认知功能下降几率降低，三项研究表明MVPA在脑可塑性方面有所改善。
通过加速度计测量，似乎与通过问卷调查、成像分析和生化标记评估的老年人认知功能的重要结果呈正相关。
