Abstract

Human body volumes in females were calculated from the measurements of body height and body weight. Empirical equations suited to express the relations of height, weight and surface area to show the female body volume were derived from the body volume measurements by means of underwater weighing method. Underwater body weights were corrected for the residual volume of lung obtained by the Rahn's three breath method. Underwater weighing was performed on 171 female subjects aged between 13 and 45 years. Subjects were divided into 4 age groups, namely, 1316 years group of 31 subjects, 16-19 years group of 48 women, 18-23 years group of college women consisted of 50, and middle-aged group (33-45 years) of 42 women. The group division was made on the basis of physical growth and development. The following results were obtained. 1. Body height (H, em), body weight (W, kg), body surface area (S, m'), and body volume (V,l) interrelated closely. VIS showed a high correlation with W/H and the coefficient of correlation was r=0.936 in the total 171 women group. Subsequently the following regression equation was obtained. V=SX (53. 25W/H+15. 69) The agreement of body volume values calculated by the empirical equation and underwater weighing was good. The mean deviation of calculated from the measured value ranged between ±O. 48 and ±O. 76 liters (standard error of estimate was between 1. 25% and 2.57%). 2. The calculated values of body volume in women were: 38.1 1 (equivalent to the body density value of 1. 0371 kg/l) in 13-16 years group, 47.1 l(equivalent to body density of 1. 0358 kg/I) in 16-19 years group, 49.6 1 (equivalent to body density value of 1. 0396 kg/}) in college women, and 49.5 1 (equivalent to body density value of 1. 0339 ks/D in middle-aged women. 3. The correlation between VIS and mean skinfold thickness of 4 sites (arm, back, waist and abdomen) was high, namely, the coefficient of correlation was r=0.724. The coefficient of correlatjon between V/S and the Rohrer index ranged between r=O. 778 and O. 915 affected by the difference in the group age of the subjects. The body volume (V) alone correlated poorly than V/S with mean skinfold thickness(r=O. 683) and the Rohrer index (r ranged between 0.524 and 0.779).
