抄録

The present study aimed to identify potential indices of mental fatigue. The participants were 15 male university students. After providing written informed consent, the participants performed a 5-minute rest period, mental arithmetic tasks (five 20-minute trials), a 5-minute rest period, and also a 5-minute rest period after a 20-minute recovery period. After each period, subjective ratings of mental fatigue were collected and the participants' performance on a simple visual search test was measured. Physiological indices were measured during both the tasks and all the rest periods. In order to investigate the indices that show mental fatigue, a comparison was executed between the results during three rest periods; before and after tasks, and after the recovery period. Significant changes were detected in subjective evaluations of fatigue, search time in the visual search test, heart rate, nasal tissue blood flow, the coefficient of variation of R-R intervals on ECG, and the total power of heart rate variability and its low frequency component. These changes were considered to be caused by mental fatigue. The results suggested that these indices could be used to assess mental fatigue.
