Abstract
This study was attempted to make new equation for predicting body composition of Japanese young females at any levels of habitual physical activity. Female athletes (n=51) and non-athletes (n=23) were measured for body composition using 16 anthropometric dimensions and hydrostatic weighing.
The analysis of covariance confirmed that the relationship between body density and skinfold measurements was significantly different between the groups. On the other hand, the relationship between total body volume and body weight or girth measurements was similar between the groups. Therefore, the prediction equation of total body volume was derived from body weight and girth measurements. The equation for total body volume was calculated as follows ; TBV=0.8912BW+0.0702CG+0.0578WG+0.0957TG-10.957 (R=0.997, S. E. E.=0.455) where TBV, BW, CG, WG and TG were total body volume in liter, body weight in kg, chest, waist and thigh girth in cm, respectively. The equation for %Fat was also calculated by substituting the equation for TBV into BROZEK et al. formula for %Fat as follows ;%Fat=(32.08CG+26.41WG+43.73TG-6.92BW-5007.35)/BW
(R=0.710, SEE=3.12).
