Statistical analysis of the beijing 2008 olympic games men's volleyball competitions

Main aim of this study was to determine the factors that affect success in volleyball through statistical analysis of 19 matches which were played in 2008 Beijing Olympics by 9 men volleyball teams (12x9=108 players) . All matches were analyzed using the ?Data Volley 2007 Professional 3.4.0? program to reach the values of each team for each skills. For each variable value that comes from the average of the data which is obtained from matches by each team and analyzed and graphics were obtained by the ?Microsoft Excel? program. Using the `?Spearman?s rho?? test in the ?SPSS 11.5? program, the relationship among the physical values and also between the physical values and success were analyzed .As a result of this study, negative and significant high level correlation(r=,917) was found between success and break-point. The block was obtained as the determinant skill that differentiates the teams in the criterion of being successful or not. The results also showed that there was a positive significant relation (r=,817) among attack efficiency and success while there was a negative significant correlation (r=,720) among side-out and success. It was found that the efficiency of the attack and the efficiency of the block had very high relations with the success. However, the results showed that the block efficiency was much more determinant factor than the attack efficiency.The relationship between the technical and physical parameters were also studied but no significant relations could be obtained among them .Key words : Volleyball , Match Analyses , Olympic Games.
