On the basis of the body density, described in the first report, the body fat mass was estimated, and its relations with the skinfold thicknesses at and girths around various parts of the body were studied. The subjects were divided into sport group and non-sport group, and the former was further subdivided by the variety of sport. And the results from different groups and subgroups were compared with each other. The principal findings were as follows: 1) The mean weight of fat(Fat-Kg)for the total 111 cases was 8.0±3.07(X±SD). The mean for a single sport subgroup ranged 10.0?}3.28 for the judo subgroup to 6.6±1.88 for the ball game (baseball, football etc.) subgroup. The percentage of body fat mass to body. weight (%Fat) was 12.0±2.90% for the total cases, when classified by group and subgroup, %Fat was the highest 13.6?±4.44% for the non-sport group, and the lowest 10.3±2.82% for the ball game subgroup. 2) Fat-Kg was highly correlated with both skinfold thickness and girth, especially so with the former in general, giving a higher coefficient. In the judo subgroup, however, both the skinfold thickness and the girth were correlated with Fat-Kg nearly with the same coefficient. 3) when the partial correlation of Fat-Kg to skinfold thickness (total of those at triceps, subcapsular part, and abdomen on midaxillary line) was compared with that to girth (total of those of upper arm, chest and abdomen), with the thickness or the girth fixed, the coefficient was higher for the latter partial correlation than for the former in the judo subgroup. This was characteristic of this subgroup as compared with the others. 4) In the non-sport group, any significant correlation was not observed between the skinfold thickness at the triceps and Fat-Kg. In this respect, the non-sport group was distinguished from the sport group inclusive of the judo subgroup.
