This study was conducted with the aim of studying the somatotype characteristics of athletes in three different sports branches and identifying the differences in the branches. The study included a total of 58 volunteer athletes from the tennis group (n=18, age=12,05±1,73) Swimming (n=19, age 12,10±1,48) and competition (n=21, age=14,71±,46) in the age group. Anthropometric measurements of the athletes involved in the study, body mass index and somatotype values were calculated by the Heath&Carter method. The data obtained was evaluated by the Anova test and Tukey HSD test in the SPSS program. Compared with the anthropometric characteristics of athletes in different branches, there was no statistically significant difference in size length (p=0,888), body weight (p=0,520) body mass index (p=0,340) values (P0,05). In comparison of somatotype values between branches, there was no statistically significant difference between branches in endomorphic and ectomorphic values (p=0,103, p=0,232) (July0,05). The mesomorphic values (P=0,000) showed a significant difference between the branches (July 0.05).The group observed the significance between competition and tennis (P=0,000) and swimming and tennis (P=0,000). The somatotype structures of the athletes in the competition and swimming industry are mezomorphic, while the athletes in the tennis industry are ectomorphic-endomorphic. As a result, the infrastructure athletes in the competition and swimming industry have been found to have a mesomorphic structure in their body structures, unlike the tennis industry, by joining their training programs.
