Sažetak
The partial potential successfulness of the sample of 42 tennis players, aged between 12 and 14 years, was evaluated in some chosen spaces of the psychosomatic status, using regression analysis and the Tennis Expert System. The model of potential successfulness of young tennis players was designed on the basis of the existing research work and its findings. The model consisted of motor, morphological and functional dimensions. The model was tested by both methods at the highest level and also at individual levels. Regression analysis was performed separately on the motor, morphological and functional parts of the tree of partial potential successfulness model. By means of morphological predictor variables 37% of the criterion variable was explained, by means of functional variables 38% and by means of motor variables 66%. Using standardized predicted estimations for individual areas, regression analysis was also performed at the highest level of the three dimensions that explained 74% of the criterion variable.
The association among the values of the partial potential successfulness obtained through the Tennis Expert System and the criterion variable is somewhat lower as is the case in regression analysis. The value at the highest level of the model of partial potential successfulness as correlated was at its highest 0.63, the value in the space of motor dimensions 0.65, the value in the space of functional dimensions 0.53 and the value in the space of morphological dimensions 0.45. A congruity of the results obtained by the Tennis Expert System and regression analysis turned out to be 0.69 with the morphological dimensions, 0.70 with the motor dimensions and 0.88 with the functional dimensions. At the highest level of the model of partial potential successfulness of young tennis players the congruity of results turned out to be 0.78.
