Abstract

In this project, the mental stress of both young and middle to elderly aged female sales clerks in a large-scale department store in Japan was investigated. Six subjects in each of the two age groups were from 27-33 years and 49-56 years. Measures were recorded regarding the function of concentration TAF-test), CFF-test, multiple choice reaction time, the displacement of body's center of gravity per one minute with eyes opened, tapping ability test per 20 sec., crural circumference and blood pressure. Heart rate was also measured during working hours. Questionnaires were administrated to establish their attitude toward their jobs, and to evaluate their subjective feelings of fatigue and state of health.
Results indicated that the function of concentration (TAF) when compared with pre-work values was significantly reduced only in the middle to elderly group. In both groups, the CFF showed a significant lowering and the crural circumference was significantly increased compared with pre-work values. The level of CFF value and tapping ability in the middle to elderly group lowerd significantly in comparison with the younger group. However, compared with the younger group, the middle to elderly group felt a decrease in sujective feelings of fatigue and bordom. Moreover, another interesting finding was that the displacement of body's center of gravity in the middle to elderly group was markedly smaller than that of the younger group due to years spent standing erect during their work.
