Changes in somatotypes of European males between 17 and 24 years.

In order to examine the possible changes in somatotype of young males, 14 boys who had been somatotyped annually from 11 to 18 years by the Health-Carter anthropometric rating method were re-somatotyped at 24 years. The analysis focused on years 17, 18 and 24. Discriminant analysis, somatotype dispersion indices and distances, and the I-index were used to analyze the data. The findings showed a significant shift in somatotype from ectomorphmesomorph towards endo-mesomorphy between 17 and 24 years. This shift was greater than that observed by Zuk ('58), and was in the same direction. It is hypothesized that the somatotypes of males become more endo-mesomorphic from 17 years to the mid-twenties.
