我们研究了压力是否会影响疲劳，反之亦然，以及调节这种关系的因素。 50 名健康参与者（31 名女性，23.6 +/- 3.2 岁）在期末考试准备的 5 天（考试条件）和常规学期周的 5 天（对照条件）期间完成了多达 5 次压力和疲劳的瞬时评估。睡眠质量是通过醒来时的自我报告来衡量的。一组参与者（n = 25）也收集了唾液样本。疲劳与并发压力、前一个测量点报告的压力以及前一天的压力有关。然而，瞬时压力也可以通过并发疲劳、前一个时间点的疲劳和前一天的疲劳来预测。睡眠质量介导了压力和第二天疲劳之间的关联。皮质醇和α-淀粉酶不介导压力-疲劳关系。总之，应力与疲劳之间存在着相互关系。预防和干预计划都应全面涵盖压力和疲劳如何相互影响。 (C) 2015 Elsevier B.V. 保留所有权利。
We investigated whether stress may influence fatigue, or vice versa, as well as factors mediating this relationship. Fifty healthy participants (31 females, 23.6 +/- 3.2 years) completed up to 5 momentary assessments of stress and fatigue during 5 days of preparation for their final examinations (exam condition) and 5 days of a regular semester week (control condition). Sleep quality was measured by self-report at awakening. A sub-group of participants (n = 25) also collected saliva samples. Fatigue was associated with concurrent stress, stress reported at the previous measurement point, and previous-day stress. However, momentary stress was also predicted by concurrent fatigue, fatigue at the previous time point, and previous-day fatigue. Sleep quality mediated the association between stress and next-day fatigue. Cortisol and alpha-amylase did not mediate the stress-fatigue relationship. In conclusion, there is a reciprocal stress-fatigue relationship. Both prevention and intervention programs should comprehensively cover how stress and fatigue might influence one another.
