Background: The aim of the study was to determine differences in the efficiency of executing technical actions by female volleyball players taking into account their positions on the court. Material/Methods: The research material comprised results of the efficiency of female volleyball players’ technical actions (n = 98) participating in the 2015 Women’s European Volleyball Championship. The subjects were divided into five groups: receivers, middle blockers, spikers, setters, and liberoes. The following technical actions were analysed: attack, block, serve, and receiving a serve. In order to determine the differences between the studied groups, statistical tests were used. The Scheffe test was used to compare the efficiency in attack, block, and serve. Student’s T-test was used to compare receiving the serve. Results: Middle blockers are more efficient in attack than spikers by 6.82% (p < 0.05) and receivers by 9.61% (p < 0.001). Middle blockers also gain more points in the block per set than receivers (Δx = 0.39, p < 0.001), setters (Δx = 0.49, p < 0.001) and spikers (Δx = 0.35, p < 0.01). Liberoes present the efficiency in receiving the serve higher by 6.07% (p < 0.05) than receivers. Conclusions: Efficiency in attack, block and receiving a serve significantly diversifies players at differentpositions. Their positions on the court do not affect the efficiency of the serve. These differences may arise from the game tactics of the teams and may be related to different tasks realised at particular positions.

Introduction. Effective preventive measures are necessary not only to reduce the incidence of injuries in volleyball, but also to reduce the costs caused by these injuries. Aim of Study. The aim of the study was to investigate the impact of 10-day proprioceptive training on the results of the functional movement screen FMS in young female volleyball players. Material and Methods. The study was conducted in a group of twelve female volleyball players. The training was performed daily in the form of a circuit for 10 consecutive days. The FMS test was run three times. The first two trials, in one week interval, were conducted before the start of the proprioceptive training. The third assessment was carried out after the completion of 10-day proprioceptive training. Results. The analysis showed differences between studied measurements: first and third as well as second and third (p ≤ 0.001) in the following FMS test trials: deep squat, hurdle squat, push-ups and rotational trunk stability. Based on mean values of the overall FMS test score, an improvement was observed after the application of 10-day proprioceptive training (p ≤ 0.001). The study showed that the number of asymmetries found in the FMS test decreased by 50% after the application of the training. Conclusions. The applied proprioceptive training positively influenced the number of points obtained in the FMS test. It also reduced the number of asymmetries and caused that all of the subjects obtained the total FMS test results of ≥17, which is believed to reduce the likelihood of injury. Research results indicate that proprioceptive training should be taken into account by volleyball coaches in daily training.

Introduction. Modern statistical methods related to team games can be very helpful in improving the quality of analysis. Aim of Study. The aim of the paper was to identify differences in the efficiency of executing technical actions by teams participating in the Men’s and Women’s European Volleyball Championship in 2013-2017, with consideration for the gender and the place taken in the final classification. Material and Methods. The research material consisted of teams (n = 96) divided into five groups: 1 – places 1-4, 2 – places 5-8, 3 – places 9-12, 4 – places 13-16, 5 – all teams. The results of efficiency in the serve, reception, setting the reception, the attack and the block were analysed. Results. Female teams were more efficient than the male ones in reception by 4.45% (p < 0.05) and in the block by 0.32 point (p < 0.05), while the male teams were better than the female ones in setting by 10.24% (p < 0.001) and in the attack by 7.46% (p < 0.001). Female teams from places 1-4 were more efficient in the serve by 0.44 point (p < 0.01), in setting by 13.93% (p < 0.001), in the attack by 9.00% (p < 0.001) and in the block by 1.00 point (p < 0.01) in comparison with teams from places 13-16. Similar results were obtained by men: in the serve by 0.44 point (p < 0.01), in setting by 13.93% (p < 0.001), in the attack by 9.00% (p < 0.001) and in the block by 1.00 point (p < 0.01). Conclusions. The obtained results indicate differences between male and female volleyball players. This necessitates using different methods of training. The efficiency of performing technical actions differentiates between teams from places 1-4 and 13-16. Therefore, in training control, coaches should primarily focus on tools that allow an assessment of the efficiency of male and female players in individual technical elements.

Background: The aim of the study was to analyse sports results and the somatic composition of participants in the 2014 FIVB Volleyball Men's World Championship held in Poland. Material/Methods: Research material involved volleyball players participating in the World Championships (n = 280). Their age, height, weight, one-arm spike reach, both-arm block reach, and Rohrer’s index were analysed. The mean value of the features and their derivatives in individual teams and groups were calculated and verified using statistical tests (t-Student, Mann-Whitney and Cochran-Cox) if the differences were significant. Results: The subjects’ mean age was 26.33 years (SD = 3.90), body height 198.41 cm (SD = 6.05), body weight 89.40 kg (SD = 8.43), spike reach 344.08 cm (SD = 13.37), block reach 326.68 cm (SD = 13.09), Rohrer’s index 1.15 (SD = 0.10). 90.36% of the volleyball players manifested the leptosomatic body composition, 9.28% the athletic one, and 0.36% the pyknic one. The highest and the lowest ranked teams in the analysed tournament significantly differed in the spike reach (P < 0.005) and in body height (P < 0.015). Conclusions: The leptosomatic body composition type is dominant among volleyball players at the top level of sports championship. The body height and the spike reach significantly differentiate the top and the bottom ranked teams participating in the 2014 FIVB Volleyball Men's World Championship. These characteristics should be taken into account in selection to play men's volleyball.
