From the results of this study, there was a significant difference (p<0.05) between 2018 and 2022 in the number of back attacks, points, scoring rate, and number of bats for OH players. A significant difference (p<0.05) was observed between 2018 and 2022 in the score ratio of back attacks in the league as a whole and the score ratio of OH players. In 2018, only a significant positive correlation (r=0.708) was observed for the set rate and back attack of each team, but in 2022, each team's A significant positive correlation (r=0.798) was observed between the set rate and the goal scoring rate of the team as a whole, and a strong positive correlation (r=0.779) was also observed for the goal scoring rate of the OH players. A moderately significant correlation (r=0.684) was observed, and a moderately significant correlation (r=0.644) was also observed for OH players' back attack scores. This result suggests that it is necessary to pay attention to the back attack trends of OH players in terms of offensive tactics at the top level of university men's. In addition, in order to incorporate tactics according to the team situation, we believe that it is important to collect information in advance, such as the opponent's tactical tendency and the effective tactical pattern of the own team, and we were able to confirm the necessity of establishing the environment and system.
