The aim of this study was to describe the somatotype of Chilean professional soccer players, and to determine the variability in the somatotype by playing position. One hundred professional male players (age 23±4.4) participants in the Chilean national soccer championship were included in the study. We performed the measurement of 10 anthropometric variables according to the rules of the International Society for the Advancement of Kinanthropometry (ISAK). We calculated the 3 components of the Heath-Carter somatotype for each playing position. The somatotype of the sample group presents a balanced mesomorph classification (2.25-5.32-2.26),especially among defenders. The positions with less dispersion in their somatotype were the defenses and goalkeepers, while the flyers and forwards show more variability. In conclusion, although there is a common somatotype, differences in the variances between playing positions provide information about the relevance of morphological optimization in a playing position.
