Table 4: Position vs. jumping parameters of the studied players. biggest difference between libero and the outside hitter. Variations in the positions also occur in the power of lower limbs, most noticeable for attackers and mid-players. The Dunn test presented in Table 7 confirms the statistical significance of the three-movement parameters. At the same time, it shows that in the case of the pace of movement, there are differences between the libero and the middle and receiving players. TStance has the greatest difference between the middle and receiver and the stride width between the setter and receiver. \begin{table}
