In order to product the equation for estimating body fat using the circumference and skinfold methods, twenty healthy female university subjects were participated in this experiments. The results obtained in this study are summarized as followed. 1. Body density and %fat determined by underwater weighting method was 1.0580±0.0092 and 17.7±3.8% respectively. 2. Body circumferences which presented the hightest correlation with the underwater weighting was abdominal (r=0.736, P＜0.001) and hip (r=0.587, P＜0.01) circumference. 3. Skinfold which presented the hightest correlation with the underwater weighting was abdominal (r=0.636, P＜0.01), subscapular (r=0.559, P＜0.01) and Pectoralis major (r=0.554, P＜0.01) circumference.
