本研究的目的是检查的假设，即日本女护士的心率变异性（HRV）的总功率（TP）的组成部分减少将显示在夜间工作的交感迷走神经活动的不平衡。我们对10名健康女性护士（30.9 ± 3.1岁）进行了这项研究，夜班时间为16：00至09：00。测量心率（HR）和HRV的不同频率功率分量以估计交感迷走神经活动的个体模式。交感迷走神经活动的潜在不平衡被定义为较高的HR和降低的TP，受试者被分为两组的基础上夜班前的TP值。为了评估中枢疲劳，我们对所有受试者在夜间工作前后进行了三种不同的疲劳测试。我们的研究结果表明，降低心率变异性的护士有交感迷走神经活动的不平衡，但不受中枢疲劳的影响。
The aim of this study was to examine the hypothesis that Japanese female nurses with a reduced total power (TP) component of heart rate variability (HRV) will show an imbalance in sympathovagal activity during night-time work. We carried out this study on 10 healthy female nurses (30.9 ± 3.1 years) working a night shift from 16:00 to 09:00. Heart rate (HR) and the different frequency power components of HRV were measured to estimate individual patterns of sympathovagal activity. A latent imbalance of sympathovagal activity was defined as higher HR and reduced TP, and subjects were divided into two groups based on TP values taken before the night shift. To evaluate central fatigue, we performed three different fatigue tests before and after night work in all subjects. Our results suggest that nurses with reduced HRV have an imbalance of sympathovagal activity but do not suffer from the effects of central fatigue.
