Six healthy college girls were selected as subjects, each two of them belonged respectively to obese, ordinary, and lean type, of each type one being tall and the other short in height.Besides ordinary biometrical measurements, center of body gravity, body density, basal metabolism, relative metabolic rate (RMR) of walking and Step Test, and some components of blood and urine were measured.The greatest difference between the obese and lean typed girls was found in skinfold, the former being several times greater, and the next remarkable differences were seen in circumferences especially of thigh, abdomen and upper arm.The basal metabolism per kg, body weight was markedly lower nearly by 40% in the obese than in the lean, whereas expressing per unit of body surface or of fat-free mass there was little difference between the two types.RMR in speedy walking showed a distinctly higher value in the obese than in the lean, though a little difference was observed in low speed walking.RMR in Step Test of the obese girls was higher as much as 50% than of the lean girls.Though no difference was seen in specific gravity of whole blood, serum cholesterol concentration was much higher in the obese and 17-ketosteroid excretion per day per kg. was also farely more in the obese than in the lean girls.
