The purposes of this study were to determine the anthropometric, body composition, and somatotype characteristics of elite Turkish junior female tennis players, and to compare their values with the normative reference group. Methods: Subjects were top national female junior tennis players (n= 12, age= 15.9 ± 1.1 years) who participated in winter Fed Cup development camp in 2016. A total of 16 anthropometric variables (height, weight, eight skinfolds, four girths, and two breadths) were measured. BMI, body fat percentage (Siri, 1956), muscle mass percentage (Poortmans et al., 2005), sum of skinfolds (three, six, and eight), and somatotype components (Carter and Heath, 1990) were calculated accordingly. Results: The mean height and weight values of subjects were found as 169.5 ± 5.8 and 64.1 ± 9.1 respectively. The average scores for body composition parameters were as such; 22.3 ± 3.3 for BMI, 28.0 ± 3.6 for body fat (%), 44.3 ± 13.6 for sum of three skinfolds, 105.7 ± 28.7 for sum of six skinfolds, 133.8 ± 36.7 for sum of eight skinfolds, 38.9 ± 2.1 for muscle mass (%). The mean somatotype profi le of the subjects was determined as meso-endomorphic (4.1 - 3.4 - 2.6). Discussion: Results were compared with the fi ndings of the Sánchez-Muñoz et al. (2007) which investigated the morphological characteristics of best junior (n= 12, age= 15.9 ± 0.6 years) female tennis players in the world. Comparison indicated that participants of the study are heavier (+ 2.1 kg) but shorter (- 0.5 cm) than their top ranked counterparts. They have higher values for BMI (+ 0.8 kg/m2), sum of six skinfolds (+ 3.5 mm), and sum of eight skinfolds (+ 9.5 mm). On the other hand, they have lower values for percentage of body fat (- 0.6), sum of three skinfolds (- 0.6 mm), and percentage of muscle mass (- 6.0). Results also revealed a discrepancy between the somatotype profi les. Dominant component of top ranked players was stated as mesomorph (3.7 – 4.6 – 2.9) by Sánchez-Muñoz et al. (2007) whereas participants of the current study were found as endomorph dominantly. In conclusion, this is the fi rst study that analyzes the morphological features of top Turkish junior female players. Results of the study mainly suggest and recommend strength and conditioning coaches of the top Turkish junior female players to dwell on increasing the percentage of muscle mass that may alter the body sizes of the players and consequently may boost their performances.
