The aim of the study was to determine the kinanthropometric parameters of swimmers placed in talented youth groups of the Slovak Swimming Federation, related to their swimming specialisation. The selected group consisted of 35 swimmers [13 boys and 22 girls], and the average age of the group was 13.8 years. The following basic anthropometric indicators were recorded: body height, body weight, ten skinfolds, and width parameters: epicondylus humeri, epicondylus femoris and thigh and arm circumference. A standard anthropometric set was used in order to gain the data, which served as a basis when determining the subcutaneous fat percentage and the somatotype by means of Somato software. Based upon the information obtained, the swimmers were consequently divided into five categories of motor performance, reflecting the relation between the somatotypes and kinetic abilities of the swimmers. The swimming specialisation was determined by the performances with the highest points scored during the calendar year. The results of the selected group point at a significant heterogeneity of kinanthropometric parameters. It is highly probable that, when selecting a swimming discipline specialisation, the somatotype requirements of particular swimming styles were not taken into consideration. Ectomorphic component was dominant with 51,4% and the average somatotype was 2,7-3,2-4,3 for boys and 3,6-3,0-4,0 for girls. The average value of subcutaneous fat was defined as low, 11,8% at boys and reduced, 16,2% at girls. Predominant category of five categories of motor performance was determined as D at boys and A at girls.
