The aim of the study was to determine the anthropometric characteristics and body composition in young Chilean elite tennis players aged 14 to 16 years. It was a descriptive crosssectional study. A non-probability convenience sampling of 84 tennis players (58 males 15.5 +/- 0.76 years old and 26 females, 15.3 +/- 0.8 years old) was selected. Anthropometric variables of weight, height. sitting height, skin folds (biceps, triceps, subscapular, supraspinal, abdominal, anterior thigh and medial leg), perimeters (flexed arm, middle thigh and leg) and diameters (humerus and femur) were evaluated. Anthropometric analysis and calculations were performed to determine the body composition and somatotype of the participanting subjects. The results for males were, body weight 64.3 +/- 7.94 kg, height 1.74 +/- 0.08 in, percentage of fat 16.6 +/- 4.1%, balanced mesomorph component. The females had a body weight of 49.8 +/- 6.9 kg, height of 1.65 +/- 0.03 in, percentage of fat 19.3 +/- 4.8%, balanced ectomorph component. In general, both groups showed similar anthropometric and body composition characteristics as compared to other groups of young tennis players, with the exception of the somatotype in the case of the females.
