In order to analyze the cause and effect of accidents by middle-aged and elderly workers engaged in janitor services, a physical fitness test recommended for elderly people was conducted in 1988 and 1995. 0ne hundred male and two hundred fifteen female workers participated in either of the tests. 0n the other hand, mental and physical factors were analyzed form the reports on accidents occurred during janitor services. Change in the rate of various types of accidents due to aging was then analyzed as relative to physical fitness levels of different age groups. Results of the physical fitness tests showed the age related change in grip and reflex. Marked deterioration on both factors was found in their 40's. Suppleness of male workers continuously deteriorated when they get old. Analyses from the reports showed that falling down was most frequent and occurred during floor polishing. The rate of accidents by falling down increased with age for male workers. However, it rather decreased with age for female workers due partly to their total fitness levels that do not change with age that much. The most plausible cause of falling down may be loss of body balance. We have then focused on the relationship between physical fitness and the rate of accidents. According to the multiple regression analysis, falling down may be well correlated with grip and body balance. Therefore, middle-aged and elderly workers must undergo a physical fitness test periodically for prevention of accidents.
