研究已经证明了睡眠和身体活动之间的相关关系，尽管这项工作在很大程度上是横截面的，并且未能证明时间关系。这项研究的目的是测试睡眠和身体活动之间的日常双向关系，以及这种关系在工作日和周末之间是否存在差异。54名健康的年轻人在6天的研究期间佩戴Fitbit Flex来测量睡眠和身体活动。结果混合线性模型显示，体力活动不能预测随后的夜间睡眠。然而，当参与者的睡眠时间超过他们自己的平均总睡眠时间，并且在睡眠开始后超过他们自己的平均清醒时间时，这预示着第二天的身体活动较少。结论结果表明，在健康的年轻人中，体力活动可能不会促进健康的后续睡眠，但睡眠时间和连续性以自己的方式影响体力活动。年轻人可能会对健康促进工作做出不同的反应，更好地了解这些时间关联可以提高这些工作的有效性。
Background Research has demonstrated a correlational relationship between sleep and physical activity, though this work has been largely cross sectional and fails to demonstrate temporal relationships. The purpose of this study was to test the daily, bidirectional relationships between sleep and physical activity, and whether this varied between weekdays and weekend days. Method Fifty-four healthy, young adults wore a Fitbit Flex to measure sleep and physical activity during a 6-day study period. Results Mixed linear models revealed that physical activity did not predict subsequent night's sleep. However, on nights when participants had longer than their own average total sleep time, and greater than their own average wake after sleep onset, this predicted less physical activity the following day. Conclusion Results suggest that, in healthy young adults, physical activity may not promote healthier subsequent sleep, but sleep duration and continuity influence physical activity in their own way. Young adults may respond differently to health promotion efforts, and a greater understanding of these temporal associations can enhance the efficacy of these efforts.
