Generally, the weight as well as the height have a tendency of increase of recent years.a) Generally, the Koreans have heavier weight, are taller than the Japanese, but slightly smaller than the Europeans.3. Generally, the Rohrer's index in youth is larger, in male than in female, but this difference gradually decreases with age and above 13 the index inl, male becomes smaller than in female.4. The span of arms is slightly smaller than the height with the difference in sex and age.5. The average span of arms of Koreans is slightly larger than the cbrresponding measure of Japanese, but smaller than that of Europeans.6. The span of arms of Europeans is larger than their height, but in Koreans the span is smaller than their height.
