Title: Relationship between quality of serving and the defensive phase at net in men Volleyball at the Olympic Games 2008 in Beijing. Objective: The purpose of this thesis was to find out relationship between quality of serving and the defensive phase at net in elite volleyball teams. The thesis should also give a more detailed view on progress of this relationship in time, and to show what is the character of the relationship in best teams. Methods: The main method used in this work was, standardized indirect observation.

Results: The results refer to significant relationship between quality of serving and the defensive phase at net.

By comparing of this relationship in best teams we did not find statistically significant differences, but we consider as a big advantage for team to be able to group a two-person block after poor quality service.
