The results obtained were as follows.\n1. Though 2/3 of the subject took excercise regularly, mean body density was 1.0751 ± 0.0117g/m1.\nBecause of the characteristic of the subject (2/3 excercised ). the average value of 4°k/body weight was\nexpected to be rather high. However it was 2.19 ± 0.19g/kg, which was lower than that for Katsunuma\nand Taguchi et a1. at the ages of the subject.\n2. As for the estimation of the percent body fat from body density and 4°k, the percent body fat\nobtained from 4°k ( 17.59 ± 7.21% ) tended to be higher than that from body density ( 10.93 ± 4.64% ).\n3. On the estimation of body density and the fat contents from the anthropometric measurements,\nskinfold thichness. circumferences and physique index show higher correlation coefficients in due order.\nAs for the regional correlation of body density and fat contents \\vith the skinfold thickness. abdomen and\nsuprailiac were more highly correlated than the two regions such as triceps and subscapular.\nConsequently it would be highly required to involve these two regions to descuss body composition from\nthe viewpoint of skinfold thickness.\n4. Mean values of body density ( g/ml ) and
