The Statistical Analysis of the Game Actions of the Middle-Blocker Based on the Application of the “Data Volley” Software

Abstract

The purpose of the present study is to increase the action efficiency of the center players in the Arcada Galaţi Club by using the ”Data Volley” Software, analysing the attack and defense of our own players, as well as the analysis of the opponent centre players participating in the national senior voleyball championships. As coaches of the Arcada Galaţi team it was possible for us to access the tracking statistics of 24 centre players participating in the 2018 National Senior Volleyball Championships and evaluate our own centre players in relation to the national level statistics, as well as the actions within the team. In the ample statistics for each play action, rotation, upon analysing 18 matches (stage I-III) we observed the efficiency of the serve and attack at national level as 43% and 36% respectively, as compared to 48% and 43% as it was recorded for the average centre in Arcada Galaţi.The differences of 5% for the serve and 7% for the attack over the national level point to an advantage in the attack phase. The centre play’s low blocking efficiency of 10% as compared to the 40% national average was the point of interest in the technico-tactical training for a three-month period, so that based on the distribution of the opponents’ passes/attacks an improvement of 8% was achieved in comparison to the initial analysis of the defense phase.
