COMPARISON OF THE SPIKE VELOCITY BETWEEN DIFFERENT GROUPS OF VOLLEYBALL PLAYERS

Spiking efficacy is one of the key factors for success of one volleyball team. The fact that one team wins most of the points in the set/match with the spike (Bellendier, 2003 ; Marelić et al., 2005) makes this element very interesting for analysis. Besides technical – tactical diversity the key factor on high competitive level is the spiking velocity. The aim of this study was to compare the spiking velocity among three different groups of volleyball players. Nineteen senior male volleyball players were divided into three different groups according to their quality: G1 (national team members), G2 (premiere league players) and G3 (second league players). Each volleyball player performed three spikes. Spiking velocity was measured using STALKER PRO radar in km/h. The means and SE were calculated for each tested group. Results between the groups were compared using ANOVA (Tukey HSD post – hoc test). Significant differences in spiking velocity were found (p<0.05). Using Tukey post-hoc test significant differences were found between all three groups (p<0.05). The speed of the spike increases according the level of the tested group (G1: 106.3±5.83, G2: 97.5±2.81, G3: 90.9±2.96). The obtained results are almost identical to the previous results obtained on similar samples (Christopher, 2001 ; Coleman et al., 1993 ; Forthomme et al., 2005). Considering the importance of a spike in the structure of points scored during a set/match it may be concluded that the spiking velocity may represent important criteria in the selection process in volleyball especially at the top level.
