Title Fire fighters' physical and mental fatigue in 24-hour shift work
Original title 24-Jikan kakujitsu kinmusha no hirō tokusei - shōbō taiin o taishō to shite [in Japanese]
Bibliographic information 1 June 1992, Vol.7, No.1, p.63-74. Illus. 11 ref.
Abstract Heart rate, blood pressure at rest, handgrip force, vertical jumping, body flexibility, physical working capacity, perceived exertion during bicycle exercise and subjective symptoms of 14 firefighters (aged 29-48) were measured for 10 consecutive days during which the subjects alternated between 24h on duty and 24hr off. The only statistically significant change over this period was a slight decrease in the height to which subjects could jump. Perceived exertion increased over the observation period for subjects in their 40s and decreased for the younger ones. Subjective symptoms of physical, mental and sensory fatigue increased over the 10 days, i.e., the 24hr off-duty period was insufficient for recovery. The 24hr shift, which involves mainly sedentary work at night, seems to produce psychological discomfort but to have little physical effect.
