以8名无经验驾驶员为受试者，在340 km的高速公路上研究了驾驶距离对3个疲劳指标的影响。使用的生理变量是0.05-0.15 Hz区域（0.1 Hz HRV）中心率变异性[HRV]的频谱值，并补充心率平均值（SD HRV）和心率平均值（HR）的SD。分析表明，0.1 Hz HRV与驾驶距离有显著相关性，而SD HRV与HR无直接关系。讨论了这种差异对3个生理变量的影响的原因，并得出结论，0.1 Hz HRV似乎是驾驶疲劳的敏感指标。
The effect of distance driven on 3 physiological variables taken to be indicators of fatigue was investigated on a 340 km highway circuit with 8 inexperienced drivers as subjects. The physiological variables used were spectral values of heart rate variability [HRV] in the 0.05-0.15 Hz region (0.1 Hz HRV) supplemented by SD of heart rate mean (SD HRV) and heart rate mean (HR). The analysis showed a significant relationship between 0.1 Hz HRV and distance driven while SD HRV and HR showed no direct relationship. The reason for this differential effect on the 3 physiological variables was discussed, and it was concluded that 0.1 Hz HRV seems to be a sensitive indicator of drive fatigue.
