In the last few years, especially at the level of senior players, the volleyball game has become very dynamic, with a remarkably high speed of execution of the game elements, which requires the utmost involvement and mobilization of the players. In this case, it is very difficult to monitor all the sequences of the game without specialised programmes of statistical analysis. The statistical analysis of the sportsmen performances is essential in professional volleyball, where top-of-the-range software programmes are used, which were designed to help the coaches. The evaluation of the players by statistical data is a tool used very often in modern volleyball. As such, the nowadays coaches constantly use the statistical analysis in all the training lessons, friendly or official games, having available at all times objective data about their own team, but also of the opposite team. Such a methodology of statistical analysis is the Data Volley software which can be used in the training process, as well as in the preparation process of the friendly or official games, of the volleyball teams, at all levels. With the help of the data offered by the Data Volley software programme, we can analyse a multitude of technical or physical indicators, tactics, basically every area related to performance. In this research we were interested in how the game qualitative indicators of the senior volleyball teams have evolved, teams which participated in the pedagogical experiment where the Data Volley software was used to obtain the most objective statistical data of the game actions.
