Abstract

This purpose of this study was to examine the influence of age and gender on whole and body regional muscle mass and distribution using dual energy X-ray absorptiometry(DEXA). The subjects consisted of healthy adult men and women who had participated in body composition studies at Korea University. The subjects varied in age(20~73 yr) and body mass index(15.6~42.5). None of the subjects was taking medications known to affect the study variables. They were divided three groups according to age. The major findings in this study were summarized as follows : 1.
