Analysis of measurements on physique, skinfold thickness and plasma protein concentration obtained from a sample of 2,219 college entrants (male students: 1,947 persons and female students: 272 persons) in the academic year of 1979 disclosed the following conclusions. 1. Average values of the height, weight and chest circumference for the male and female students were as follows: Male students Female students Height 169.3±5.26㎝ 157.0±5.01㎝ Weight 58.7±6.89㎏ 51.4±5.49㎏ Chest circumf. 88.5±5.33㎝ 81.3±5.52㎝ 2. It was noted that the mean values of the physical measurements in the male students showed the significant increase in the values during the past decade since 1970 (p＜0.01), but there were no differences in the female students. 3. Mean values of skinfold thickness in both sexes were as follows: Male students Female students Triceps skinfold 8.52±4.18㎜ 20.21±6.54㎜ Subscapular skinfold 10.24±6.24㎜ 22.40±6.54㎜ 4. Average values of the skinfold thickness, except the triceps skinfold thickness for the male students, showed the emarkable increase in comparison with those in 1970. 5. The highest value in the skinfold thickness appeared at their age of 1718 in both sexes, then showing the sharper decrease with age in the female than in the male students. 6. Average values of plasma protein concentration in the female students, 7.92±0.46g/100ml, was significantly higher than that in the male students, 7.78±0.10g/100ml. 7. The average plasma protein concentration in the female students reached the highest value at their age of 17-18, dropping sharply with age. No significant difference by in plasma protein concentration age was found in the male students. The differenc in the plasma protein concentration between sexes was found only in groups under 20 years of age. 8. It was evident that there was no correlation of plasma protein cencentration on physical measurements and the skinfold thickness in both sexes.
