Background. Volleyball has developed into one of the fastest, strongest and spectacular sports nowadays, improving the speed of the game, strength of attacks and long rallies with a good defence technique. Statistics are often used for an objec­tive analysis of volleyball parameters, coaches seeking to improve weaker aspects of the game and find new ways of training.

Aims. The aim of the study was to calculate the effectiveness of all the attack players distributed in three positions, in the case of the CSU Medicina Tîrgu Mureş team, during the 2016-2017 National Volleyball Championship.

Methods. Following our objective, we determined the quintiles and divided the value range of effectiveness: round 1-22 into five parts, with 5 grades from 1 to 5. The analysis of the relationship between the two variables and the intensity of this relationship was calculated with the Spearman rho r correlation coefficient.

Results. For service in the first part of the championship, we registered the average score of 2.8 points, whereas in the second part the score was 3.2 points. As far as attack was concerned, in the first part of the championship the average score was 3 points compared with 2.4 points in the second part. The 3.5 points average in receiving was better in the first part of the championship than the 3 points in the second part.

Conclusions. The data provided by us are important, but not exclusively as a support for training; the athletes’ level of training and the way they interact with the court remain a determining factor in winning games.

Key words: volleyball, sports performance, training, athletes, attack.
