This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.
本研究通过比较健康老年女性在4个月运动训练期间进行有组织锻炼的日子和没有进行有组织锻炼的日子，调查了运动对睡眠结果的急性影响。本研究中的参与者（n = 51）在干预中期和干预结束时，至少有3天进行有组织锻炼和3天没有进行有组织锻炼后，有手腕佩戴式活动记录仪记录的睡眠数据。运动干预为跑步机行走。使用多水平模型来检验有组织锻炼是否会影响相应夜晚的睡眠结果。分析中总共纳入了1362个夜晚的数据。在未调整和调整后的模型中，进行一次急性有组织锻炼后的晚上就寝时间明显早于没有进行有组织锻炼的晚上。锻炼日和非锻炼日之间的其他睡眠参数没有差异。了解运动对这个研究较少的人群睡眠的影响可能有助于改善他们的整体睡眠质量。
