We integrate perspectives from research on recovery from work and perspectives from day-of-week research to predict continuous as well as discontinuous changes in vitality and fatigue. We examine whether changes in recovery experiences and sleep quality predict changes in human energy over the course of the weekend. Furthermore, we consider positive anticipation of work at the start of the workweek and effort during the workweek to predict changes in energy. We collected experience sampling data from 87 employees over the course of 12 days. In total, 2,187 observations nested in 972 days were eligible for analysis. Applying discontinuous growth curve modeling, we found that human energy increases continuously during the weekend, drops on Monday, follows a passageway trajectory from Monday to Thursday, and increases on Friday again. Changes in recovery experiences did not predict changes in energy but increases in sleep quality did. Positive anticipation of work attenuated the drop in vitality on Monday. Effort did not predict changes in energy over the course of the workweek. Our results suggest that the transition between weekends and workweeks and vice versa accounts for considerable changes in human energy and that weekends are recuperative, particularly because they provide the opportunity for better sleep.

过渡中的连续性：结合恢复和每周的角度来了解员工在每周 7 天的精力变化

我们整合了工作恢复研究的观点和每周研究的观点，以预测活力和疲劳的连续和不连续变化。我们研究了恢复体验和睡眠质量的变化是否能预测周末期间人体能量的变化。此外，我们考虑在工作周开始时对工作的积极预期以及在工作周期间预测能量变化的努力。我们在 12 天内收集了 87 名员工的经验抽样数据。总共有 2,187 次嵌套在 972 天内的观察符合分析条件。应用不连续增长曲线模型，我们发现人体能量在周末持续增加，周一下降，周一到周四遵循通道轨迹，周五再次增加。恢复体验的变化并不能预测能量的变化，但睡眠质量的提高可以。对工作的积极预期减弱了周一活力的下降。努力并没有预测工作周过程中的能量变化。我们的研究结果表明，周末和工作周之间的过渡以及反之亦然是人类能量发生相当大变化的原因，而且周末是恢复性的，特别是因为它们提供了更好的睡眠机会。
