DIFFERENCES IN THE CONDITIONING AND MORPHOLOGICAL CHARACTERISTICS BETWEEN JUNIOR AND SENIOR VOLLEYBALL PLAYERS

The intention of this research is to determine if there are statistically significant differences in the indicators of motor and functional abilities and morphological characteristics between two groups of volleyball players of different age categories, that is, between juniors and seniors. The sample of subjects is composed of 12 junior (17, 8 &plusmn ; 0, 72 years) and 9 senior volleyball players (22, 2&plusmn ; 2, 1 years). For the purpose of this research a battery of tests including 14 variables is made, eleven of which serve for the evaluation of motor and functional abilities and three for the evaluation of morphological characteristics. For all 14 variables, including the AGE variable, descriptive parameters (mean and standard deviation) are calculated, and statistically significant differences between juniors and seniors are estimated using Student&#8217; s t-test for independent samples on the level of significance p<0.05. Significant differences are found in the following variables: Height of jump in block and spike (BLJH and SPJH), Spike reach (SPREACH), Volleyball polygon (VOLPOL), and finally, Running 12-minutes (RUN12MIN). From the obtained results one can conclude that seniors achieved significantly better results than juniors in the variables that estimate the explosive jumping performance and specific quickness, and significantly worse results in the variable that estimates aerobic endurance.
