The aim of this research was to determine the extent of the influence of the power of back and leg extensor muscles on the specific motor skills of young, school-aged water polo players. The sample of participants in this paper consisted of 20 water polo players (N=20), chronological age 12-14, average body weight 85,95kg (±27,15kg), average body height 174,5cm (±10,25cm), seated height 84,25cm (±7,55cm), arm range 183,70cm (±11,30cm), average thorax volume 103,15cm (±15,65cm), upper arm volume 33,45cm (±6,75cm), upper leg volume 62,10cm (±10,60cm) and body mass index 26,02 (±7,05). The anthropometric characteristics were measured using standard anthropometric instruments (GPM, Switzerland). In order to evaluate muscle power, the IMADA 32X-1100 Japanese digital instrument for measuring power, with the software program WinWedge 3.4, was used. In order to evaluate the specific motor abilities, we used a battery of 6 tests (4 tests for the evaluation of swimmer fitness in the horizontal position and 2 two tests for the evaluation of specific motor skills in the vertical position of water polo players). In order to determine the level of muscle power influence we used the canonical correlation analysis and the regression analysis. By using Bartlett`s Lambda test we determined that the variables of power and specific motor tests are linked to a single pair of canonical factors at the B=0,05 level. The canonical correlational analysis indicated that the greatest influence of muscle power was realized on the variable 30SCBJ (-0,76). The regression analysis showed that there is a midintensity correlation between absolute and relative values of back extensor muscle power and the tests of specific motor skills. A partial analysis of the criterion variables indicated that the factors of muscle power realize the greatest statistically significant influence on the 10XCBJ test at the level of B=0,05. The results of this study have indicated that the program based on specific extensive high intensity exercise can achieve significantly better results in the development of certain anthropological dimensions, as well as that they are significantly correlated in the sample of young water polo players. The generalization of the results obtained in this study can primarily be applied to the population of young water polo players included in this study.
