Young players took part in 27.03% of the team’s tactical and technical actions. Their effectiveness was 5.81% (p < 0.05). There was a process of unbalancing the team, which led to a decrease in sports results. Comparative analysis of the tactical and technical actions of young volleyball players of the Podillia team in the 2022/2023 and 2023/2024 seasons showed high effectiveness of their actions.

The effectiveness of the group of young players was within 22.26÷26.44% (p < 0.01). Conclusions. The introduction of young players to the main composition of a professional volleyball team is a complex, dynamic process of adapting players to the peculiarities of tactical and technical actions in a new team. Rejuvenation of the team can lead to changes in the quality of the team’s tactical and technical actions and, as a result, to an improvement in results or their deterioration.
