Effect of New Rules on the Correlation between Situation Parameters and Performance in Beach Volleyball

The aim of the study was to assess the effect of basic technical-tactical elements, i.e. specific motor abilities, on performance in beach volleyball, with special reference to differences between the old and new official rules. Analysis of variance for 6 variables of technical-tactical elements between the winning and defeated teams included a sample of 129 sets played according to the old official rules (1995 and 1996) and 74 sets played according to the new official rules (2003). This was followed by regression analysis between these technical-tactical elements as predictors and a variable, i.e. score difference at which the team won or lost the game, as a criterion. Results of the analysis of variance between the winning and defeated teams showed highest differences in the performance of attack-hit, followed by counterattack- hit and blocking in both game types. However, difference in the performance of serve reception, serve, and field defense between the winning and defeated teams decreased significantly with the use of new rules as compared with the old ones. Results of regression analysis indicated the sets played according to the new rules relative to old ones to increase the predominant impact of technical-tactical elements in the above-net actions, especially attack-hit and block, on the final result in beach volleyball
