摘要：

The aim of the current study was to examine the relationship between workload and objective/subjective fatigue for a regularly rotating work schedule. Twenty male shift-workers working a 12-h schedule at a metallurgic smelter were involved in the study. Data were collected for a 14-day period while the participants continued their work schedule and duties. Shifts with high and low workload were separated and compared. Trends were observed for the increase of fatigue with a higher workload. Subjective fatigue was significantly higher at the end of the 12-h night shift (P<0.05), and psychomotor vigilance test lapses occurred during the first half of the night shift (P<0.05). These results imply that the relationships between workload, performance and subjective fatigue are complex and that further research is required.
