Plyometric training on different surfaces may be associated with different training-induced effects on some neuromuscular factors related to the efficiency of the stretch-shortening cycle
(Impellizzeri et al., 2008). Vertical jump on sand surface is lower than hard surface because of sand surface is more instability and this instability decreases maximum power and take off
velocity.Furthermore jump kinematics is different on sand surface than hard surface (Giatsis et al., 2004). Arazi et al. (2014) recommended that training on hard surface for sprint, jump performance
and trainin on sand surface for agility and strength performance according to results their study performed 6 week plyometric training on different surface of healthy male subjects (Arazi et al.,
2014). Although the majority of studies in volleyball players performance were evaluated on hard surfaces and there are very limited studies the effects of different hard surfaces such as wooden or
synthetic material on volleyball performance. Therefore the aim of these study was to investigate the effect of 8 week plyometric training performed on two different surfaces that wooden and
synthetic surfaces on jumping performance of adult male volleyball players.
Thirty six male volleyball players whose ages differs between 18-24 were voluntarily participated in this study. All participants were randomly divided 3 groups; wooden surface (n:12), synthetic
surface (n:12) and control group (n:12). Wooden and synthetic surface experimental training groups performed 3 days a week for 8 weeks.The training program that include 20 different plyometric
exercise drills and these drills performed through that 8 week training period. All tests were performed by the subjects for three groups before and after 8-week plyometric training. SPSS program was
used to evaluate the data. Paired samples t test was used to determine the difference between measurements. One-way ANOVA was performed to determine the difference between groups.
Statistically significant difference was found after the 8 weeks plyometric training on the vertical and horizontal jump parameters in favor of the experimental group (p<0.05). But, no significant
difference was found between wooden and synthetic surface volleyball players jump performance (p>0.05). It is observed that wooden and synthetic surface doesn't affect to jump performance of
volleyball players. According to these results plyometric training program effective on jump performance of volleyball players despite this training surface doesn't effect on jumping performance.
As a conclusion, plyometric training was found to increase the jump capacity of volleyball players. The comparison of wooden and synthetic surface groups did not revealed a statistically significant
difference which shows that wooden and synthetic surfaces has not a positive effect on athletes jump performance and only plyometric training makes a positive difference. This study will contribute to
literature and will shed light on sport training studies to be conducted and will contribute coaches while preparing training programs.
