The part difference of change of body fat in Japanese young women

Abstract

The purpose of this study was to clarify the part difference of change of body fat in Japanese young women. Subjects were 142 healthy female university students who were living in a dormitory. In particular, 21 subjects who showed the remarkable increased percentage of total body fat were grouped as the increase group. 24 subjects who showed the remarkable decreased percentage of total body fat were grouped as the decrease group. Body weight, total and regional body fat and mus-cle volume were measured by bioelectrical impedance analysis method. Each item was measured for two times in June and December. The difference of change in the percentage of body fat of a trunk showed the highest value in parts of the body. The difference of change in the percentage of body fat of an arm was higher than that of a leg. From these results, the part difference existed to a change of the body fat. It was suggested that the part in which body fat tends to increase is the part in which it tends to decreases.
