The aim of the research was to use a system of 25 variables of morphological characteristics on a sample of subjects numbering 200 top athletes, all males (50 handball players,50 volleyball players, 50 basketball players, 50 soccer players), aged 18 to 30, in order to determine their factor structure, which would be in aid of more rational procedures for the continual selection of athletes in these sports and the transformational training process. By means of the component analysis (the direct oblimin) and the GK criterion (ë≥1.00) used to obtain the common characteristic roots and the explained segments of common variance, five latent variables were isolated for the handball players (body mass and voluminosity and the subcutaneous fatty tissue of the upper body, the longitudinal dimension of the skeleton, the subcutaneous fatty tissue of the lower extremities and upper àrm, the transverse dimension of the lower extremities, the transverse dimension of the elbow and shoulder), six latent variables for the volleyball players (the transverse dimension of the wrist and body volume and mass, subcutaneous fatty tissue of trunck, longitudinal dimension of skeleton, the transverse dimension of knee and foot length, lower leg skin folds and fatty tissue of the upper arm,elbow diameter), another five latent variables for basketball players (the longitudinal dimension of the skeleton, body mass and voluminosity and subcutaneous fatty tissue of the trunck, the subcutaneous fatty tissue of the lower extremities and upper arm, transverse dimension of the lower extremities and the wrist, the transverse dimension of pelvis) and six latent variables for the soccer players (the longitudinal dimension of the skeleton, the subcutaneous fatty tissue of the lower extremities and upper arm, body mass and voluminosity, the transverse dimension of the legs, shoulder and hand, the subcutaneous fatty tissue of the trunck, transverse dimension of the arms). On the basis of the identified factor structures of the latent variables, it can be concluded that we are dealing with a case of different morphological structures of the different athletes.
