• 19才から25才までの男性被検者31名の体密度測定を実施し, 身体各部位の皮脂厚及び周径から体密度を推定する式を作成した。水中体重測定法により求めた体密度は平均1.073g/m1で, 他研究にみられる数値の中間的な値を示した。ステップワイズ重回帰分析により皮脂厚と周径を説明変数とする体密度推定式を作成した結果, 皮脂厚のみを説明変数とする2変数と4変数からなる2つの式が得られた。得られた式の体密度推定精度は他研究の式と比較して体密度測定値との誤差をより少なくするものであった。This study was attempted to make equations for predicting body density of Japanese young men from skinfold and/or girth measurements. The subjects were 31 healthy young men aged from 19 to 25 years old. Body density and some anthropometric parameters, such as body weight, height, skinfold thickness and girth, were determined. The body density was estimated by underwater weighing method. Subjects were immersed underwater in the squat position and instructed to breathe out as completely as possible. Then underwater weight was measured with use of load cells. The residual lung volume measured outside the water tank by neon dilution technique in the same position as underwater weighing. The mean body density of young men was 1.073 g/ml and located atthe middle level of the other data for various populations. Two prediction of body density with a high degree of accuracy wer obtained from the stepwise multiple regression analysis. One equation used triceps and abdominal skinfolds and the other consisted of chest, triceps, subscapular and iliac skinfolds as predictor variables (cf. Table 2). On the basis of present data, differences between the actual and predicted values from variousus prediction equations obtained by the authors and other investigators (cf. Tables 3, 4) were compared to evaluate the validity of the equations.
