Sequence and effectivity of game complexes in male youth volleyball categories

The objectives of this study were: i) to analyze the sequence of game complexes in male youth volleyball categories, considering their frequency and effectivity of final actions, ii) to assess the importance of each complex within the overall game by the Social Network Analysis. We analyzed the behavior of 16 teams that participated in the Brazilian Selection Championship in 2019 in two levels (Special and First Division). The 56 games resulted in 200 sets, totaling 357,707 actions. We used the Fisher exact test, calculation of the significance of observation independence, and Social Network Analysis using eigenvector centrality. As result, there were fewer cases than expected for error in K0, continuity in KI and KV, and point in K0; there were more cases than expected for error in KI, continuity in K0, and point in KI and KV. The most frequent sequences of complexes and effectivity were K0E1-KIE2, K0E1-KIE0, K0E0, K0E2E2, K0E1-KIE1-KIIE2. The Eigenvector Centrality presented as results: KIIIE1, KIVE1, KV(2)E1, KIII(2)E1, KIII(3)E1 in the Special Division; KIII(3)E1, KIII(2)E1, KVE1, KV(2)E1, KIVE1 in the First Division. This study highlighted the main sequences, effectivity and differences that occurred in the Brazilian U-17 Male Selection Championship, assisting coaches in problem solving for training.
