Abstract This study aimed to analyse the characteristics of selected typical displacements occurring during match play in elite female volleyball players. One quarterfinal of the Serie A female Italy’s Cup was examined. One set for each of the two teams was analysed. The SIMI Motion Software was used to evaluate the movement of players on the playing surface area (2D). 14 players were tracked using the C7 vertebra as a reference point for the player’s body. A total of 27169 players’ positions were digitised. The examined displacements were those performed when doing the following actions: blocking, defensively exiting from blocking, moving to defend, preparing the spike run-up, doing the spike run-up with and without spiking, covering, receiving. The intra- and interoperatory reliability were assessed using 5% of all digitised points. The mean ± SD intraand inter-operator errors were, respectively, 0.029±.017 and .024±.016 m, then consistent with the previous literature (Jäger et al., 2007). The statistical analysis revealed the following significant (p<0.05) differences between playing positions in the mean distance of displacement: for blocking, between outside hitters/opposite attacker (0.95±.58 m) and middle blockers (1.56 ± 1.03 m); and between middle blockers and setters (0.88±1.05 m) for defensively exiting from the block, between setters (1.14±.9 m) and outside hitters (2.04±.98 m) for defend, between middle blockers (1.01±.56 m) and libero (1.37±.87) for preparing the spike run-up, between middle blockers (2.01±1.12 m) and outside hitters (2.46±1.33 m) in the majority of displacements for covering the attack, between many players positions In conclusion, the specialization of players leads to a variable displacements distance, that is linked to each position’s characteristics. Indeed, rather large distance is shown in defensive displacements by libero, in blocking actions by middle blockers, and by outside hitters for preparing the spike run-up. The present findings are useful to coaches to design training drills guided by the specific characteristics of each playing position. References Jörg M. Jäger & Wolfgang I.
