背景：在研究这些情绪时，将精力和疲劳作为一种双相情绪的研究主要集中在单个变量上，通常是疲劳。目的：本研究的目的是确定分别预测精力和疲劳感觉的因素，同时检测与这些情绪状态相关的多个领域。方法：77名参与者来自纽约北部一所小学校的医生助理、物理治疗和职业治疗项目。参与者完成了一系列调查，以衡量情绪、饮食、在校和非在校期间的脑力劳动负荷强度，以及体力活动。参与者还在iPad上完成了连线测试B部分的任务，并测量了他们的静息代谢率(RMR)和肌肉耗氧量mVO2。结果：预测变量对疲劳和能量的贡献率分别为46.1%和22.7%。在不上学的日子里，更多的疲惫与更差的睡眠质量、更多的坐着时间和更高的精神负担强度有关。更多的能量与更好的睡眠质量、更高的肌肉血氧饱和度、更低的RMR和更快的精神运动表现相关。结论：本研究结果表明，能量和疲劳是独立的，但重叠的结构可以通过不同的变量预测不同的准确性。我们的结果表明，小的生活方式改变可能是改善疲劳感的必要之举，但改善精力和疲劳感的综合干预可能是必要的。
Background: Studies examining energy and fatigue as a bipolar mood have focused on a single variable, usually fatigue, when studying these moods.Objective: The purpose of this study was to identify factors predicting feelings of energy and fatigue separately while simultaneously examining multiple domains related to these mood states in graduate health sciences students.Method: Seventy-seven participants were recruited from a Physician Assistant, Physical Therapy and Occupational Therapy program at a small school in Northern New York. Participants completed a series of surveys to measure mood, diet, mental work load intensity on school days and non-school days, and physical activity. Participants also completed the Trail-making Test Part B task on an iPad and their Resting Metabolic Rate (RMR) and muscle oxygen consumption mVO2 was measured. A backwards linear regression was used to determine the relationship between energy, fatigue and multiple variables.Results: The predictor variables accounted for 46.1% and 22.7% of the variance in fatigue and energy, respectively. More fatigue was associated with worse sleep quality, more time spent sitting and higher perceived intensity of mental workload on non-school days. More energy was associated with better sleep quality, higher muscle oxygen saturation, lower RMR, and faster psychomotor performance.Conclusion: The results of this study indicate that energy and fatigue are separate, yet overlapping constructs that are predicted with different accuracy by different variables. Our results indicate that small lifestyle changes may be necessary to improve feelings of fatigue but comprehensive interventions may be necessary to improve feelings of energy and fatigue.
