Drinking habits and health are very important topics (Imura .et al., 1988; Morimoto et al., 1988). Bando et al. (1988) reported the results of a series of investigations conducted on this subject at the Japanese Association of Rural Medicine. They stated that serum γ-glutamyl transpeptidase (γ-GTP) activity is one of the most useful biochemical indices for an objective evaluation of the consumption of alcoholic beverages (Rosalki and Rau, 1972). On the other hand, there is rapidly rising interest in athletic activities such as jogging and the marathon. It is believed to be worthwhile in the field of sports medicine as well as for daily health management to establish the range of variation of serum γ-GTP activity levels in healthy individuals who engage in these athletic activities. Studies have been conducted on the relationship between physical activities and serum enzyme activity. However most of these studies were conducted on male adults, and female adults were rarely selected as subjects. Furthermore the subjects in many studies were athletes who engaged in intense physical activity and the data were obtained before and after the athletic activity (Krauss et al., 1977; Lewis et al., 1976). In this study, three types of tests were conducted to evaluate the relationship between serum γ-GTP level and physical activity; survey on energy expenditure, a shortterm exercise test, and a 6-week exercise program.
