GAME ACTION EFFICIENCY ON VOLLEYBALL GAME STRUCTURES ACCORDING TO THE OPPONENTS’ LEVEL

Performance volleyball is composed of two fundamental game structures, namely: structure I (at own service), which includes as game actions the service, block, dig, pass and attack, and structure II (at service reception), which is made up of game actions from service, pass, attack, block and dig. This study highlights the differences between the efficiency indices of game actions on game structures at the Știința Bacău team depending on the opponents’ level. This is based on analysing the performance of the teams during the Romanian National Women’s Volleyball Championship, 1st Division, which consisted of 18 games, out of which 10 games with level 1 teams and 8 games with level 2 teams. The research hypothesis aimed at verifying the dependence of the efficiency indices of game actions on game structures according to the opponents’ level. The subjects of this study were the players of the Știința Bacău team in the 2017-2018 season. As a result of this study, we have found that there are statistically significant differences between the efficiency indices of game actions on game structures according to the opponents’ level for service (p = 0.047) and dig (p = 0.006) in structure I and for attack (p = 0.015) in structure II, which confirms the hypothesis of our research.
