Use of urgent information for evaluation and correction of biomechanical characteristics of ball serve

Aim. The paper aims to justify the effectiveness of the means of urgent information for acquiring and enhancing serving skills in volleyball players. Materials and methods. The study involved 37 volleyball players, ages 18-24. Biomechanical parameters were recorded during serving with the Videoanalyz-Biosoft 3D system. Following the analysis of the data obtained, a comprehensive program was proposed aimed at eliminating technical errors during floating or jump serves. Serving skills were evaluated with the traditional tests used in sports schools and professional training. The accuracy of hitting zones 1, 6, 5, 2, 4, and the velocity data of the ball's flight trajectory were assessed. Serving performance was evaluated using protocols in 16 matches of 5 tournaments. Results. The kinematic characteristics of floating and jump serves were identified in an unsupported position. The relationship between serve technique in an unsupported position and its efficacy was established. Based on the data of the computer system, the main technical errors were identified, and a comprehensive method aimed at enhancing serving skills was proposed. Conclusion. The paper shows the prospect for using urgent information in the training of volleyball players of different levels. The proposed method, which includes special preparatory and competitive exercises, contributed to the elimination of errors and enhancement of serving skills.
