Analysis of performance in game actions in volleyball, according to the classification

Abstract

The main objective of this research was to determine the association between performance in the different game actions and the final classification of the teams, in male volleyball. The systematic observation was used to analyse the 7888 game actions corresponding to the 21 teams participating in the male Spanish Championship, U-19 category.The study variables were: performance in all game actions and classification. A Cluster analysis was performed to establish the different classification groups. The data analysis was performed through an inferential analysis with the Chi-Square and Cramer's V. The results showed the significant association between the final classification and the actions of reception, setting, attack, block and defense (p<0.05). These results show that higher performance in all game actions, except serve, are associated with a better position in the final ranking. These results can be taken into account in the training process of male volleyball players, U-19 category. AUTHORS:Manuel Conejero INTRODUCTIONPerformance analysis in sport is based on the interpretation of different performance indicators, which allow us to develop different tactical and technical evaluations (8) , that can be useful in training planning (15) . Among the different performance indicators in sport we can highlight game actions' efficacy (5) , won/lost points (11) , set result (5) , match result (3) , and final classification (10) .In volleyball, the most used indicator for performance analysis is the game actions' efficacy (15) . The actions in volleyball are cyclical and sequential, differentiating four fundamental game complexes (2) . The complex 0 (K0) includes the action of the serve, by which the play starts, and aims to achieve direct point or reduce the options of the opposite attack (17) . Complex 1 (K1), or attack phase, includes the actions of reception, setting, attack and attack coverage. The objective of this complex is to neutralize and counteract the opposing serve, and build an attack to obtain the point (13) . Complex 2 (K2), or defense phase, includes block, defense, setting, counterattack and counterattack coverage. The objective of this complex is to neutralize and counteract the counterattack, and build a counterattack that allows to obtain the point (16) . Complex 3 (K3), or counterattack phase, includes the actions of block, defense, setting, counterattacking and counterattack coverage. Its main objective is to neutralize and counteract the counterattack from the K2 of the opposing team, and to organize a new counterattack (9) . In volleyball, there are two types of actions: intermediate and finalists. Intermediate actions are those with which it is not usual to obtain a direct point (reception, setting and defense) (11) . The finalist actions are those that usually obtain a direct point (serve, attack and block) (12) . Therefore, a player/team can get point mainly in four different ways: by serve, attack, block, or through unforced errors of the opponent (7) . Many studies have analy...

The Attack in Volleyball from the Perspective of Social Network Analysis: Refining Match Analysis through Interconnectivity and Composite of Variables

“…Match analysis, the process of recording individual game actions within a play context (Hughes & Franks, 2008), is one possible application of performance analysis. Match analysis has contributed positively to volleyball research on the influence of reception quality, attack tempo and block type on attack efficacy (Costa, Afonso, Barbosa, Coutinho, & Mesquita, 2014); on the performance links between game actions and the final ranking in the league (Conejero, Claver, González-Silva, Fernández-Echeverría, & Moreno, 2017); and on the creation of references to understand team performance in certain game actions by means of a longitudinal study (Drikos & Tsoukos, 2018).…”

Volleyball Data Analysis System and Method Based on Machine Learning

“…The complete set of all possible patterns may be too large to be covered by the information in the training data. Therefore, the difficulty of machine learning lies in how to get a good generalization from the observed data set in order to be able to generate useful models for new data [11,12]. Many machine learning algorithms have been successfully applied to a wide range of scientific and engineering problems.…”

“…22 The block is an important skill because practices a point or avoid the point. 23 The defense has the objective of avoid the point and starts the counterattack. 24 The Figure 1 illustrates the defined sequence of the skills during the volleyball match.…”
