Abstract
[b]Aim of the work.[/b] In order to identify and monitor talents, an evaluation of morphological characteristics and motor abilities of young athletes has become a must. The aim of the study was to ascertain which of the special skill tests contributed most to the differentiation of three different age groups of water polo players.[b]Methods.[/b] Two anthropometrical (body height and mass), one functional (vital capacity) and eight specific technical skills were performed by 264 players categorised in three different age groups 11 to 12 (G1), 13 to14 (G2) and 15 to 16 (G3) years of age.[b]Results.[/b] All variables under observation showed significant differences between the groups (p < 0.05). All the skills evaluated by our tests showed linear progression with respect to the growing up process. The diffe rences remain significant (p < 0.05) even when the three morphological tests were set as covariates in the statistic analysis, suggesting therefore that other factors (non-morphologic) had an important role. Using discriminant analysis we found that G1 and G2 were best differentiated by specific skill tests without a ball, while G2 and G3 were best differentiated by ball handling tests. This might be the cause of a well-known principle of motor learning that is considered in a training process – simpler motor skills without a ball are developed first and are later upgraded to more demanding ball handling skills.[b]Conclusion.[/b] Skill tests without the ball better differentiate between G1 and G2, while tests with the ball better differentiate between G2 and G3.
