The estimated maximal oxygen uptake and some indices of body size and composition, including body height, weight, and skinfold thickness at two sites have been determined on subjects aged 12, 13 and 18, 19 in Fukuoka during step work. Sex difference in maximal oxygen uptake in aged 18, 19 groups and age difference in body fat percent of weight in females were shown significantly. There were different regression equations of maximal oxygen uptake on body weight with respect to the elevations among age, sex, and region. It is considered partly due to difference in effective muscle mass that can be used to perform the work. On the other hand, the same regression line of maximal oxygen uptake on lean body mass were obtained regardless of sex and age, and it was calculated at Y=-0.012+0.055X. As a result, it esems that in relative sedentary residents irrespective of sex, age and region maximal oxygen uptake is related to the volume of lean body mass.
