Study of performance indicators in male volleyball according to the set results

Abstract

The present study aimed to identify in which performance indicators are there differences between the teams that win and lose the sets in Volleyball matches. Archival data were obtained from 65.949 game actions in 550 sets from the men's 2005 World League. The "Volleyball Information System" was used for data gathering. Descriptive statistics were performed on all variables and the student t -test was used. Kappa of Cohen analysis and percentage of agreement demonstrated good inter-observer reliability which confirmed the accuracy of observations. This study showed that the teams that win their sets have best performance in all game actions (attack, block, serve, dig, set, reception) due to higher frequency of point/excellent actions (with the exception of the number of excellent receptions) and a lower frequency of errors. The teams that win those sets have a more balanced distribution of points earned between the three terminal actions (attack, block and service) than the teams that lose their sets. For the losing teams, the attack represents a greater weight in the total points earned through the terminal actions.
