身体活动的生活方式有助于更好的执行功能。然而，目前尚不清楚高水平的执行功能是否会让人变得更加活跃。本研究使用大样本和多波数据来确定体力活动和执行功能之间是否存在相互关联。参与者是4555名老年人，他们在英国老龄化纵向研究的四次浪潮中进行了跟踪。在每一波中，执行功能通过语言流畅性测试和字母删除任务进行评估，参与者报告了他们的身体活动水平。固定效应回归表明，执行功能的变化与体力活动的变化相对应。在纵向多水平模型中，低水平的体力活动会导致随后的执行功能下降。重要的是，糟糕的执行功能预示着随着时间的推移，体力活动会减少。研究发现，这种关联比体力活动对执行功能变化的贡献要大50%以上。这是第一次有证据表明，随着时间的推移，在一大批老年人中，执行功能和体力活动之间存在明显的双向联系。
Physically active lifestyles contribute to better executive function. However, it is unclear whether high levels of executive function lead people to be more active. This study uses a large sample and multi-wave data to identify whether a reciprocal association exists between physical activity and executive function. Participants were 4555 older adults tracked across four waves of the English Longitudinal Study of Aging. In each wave executive function was assessed using a verbal fluency test and a letter cancelation task and participants reported their physical activity levels. Fixed effects regressions showed that changes in executive function corresponded with changes in physical activity. In longitudinal multilevel models low levels of physical activity led to subsequent declines in executive function. Importantly, poor executive function predicted reductions in physical activity over time. This association was found to be over 50% larger in magnitude than the contribution of physical activity to changes in executive function. This is the first study to identify evidence for a robust bidirectional link between executive function and physical activity in a large sample of older adults tracked over time.
