Abstract

Development of  biomechanical elements associated with  performance and precision of some fundamental volleyball skills is where  research is most important using exercises on  training device (vertimax), which considers  demands of  particular talent when training on it, as training is carried out according to  motor paths of each skill independently to advance  physical elements of  trained skills, which are reflected in  biomechanical aspects of each skill, which differs from  traditional methods of giving physical exercises, as  physical and skill training on this device is closer to  nature of  players' talent performance on  field. In addition,  exercises have been built on a mechanical basis that matches  character of  skill's real on-field performance.   research's objectives are to design exercises with  Verti Max device that are appropriate for  research sample's abilities and to determine how these exercises affect  development of certain biomechanical markers of young volleyball players' proficiency with  undulating serve from  jump.  research community consists of young volleyball players from Babylon clubs (Al-Mahaweel Club) youth category, numbering (16) players.  following criteria were used to choose  research sample:  They will be  Al-Mahaweel Sports Club's young players for  2022–2023 season, and there will be ten of them.   players were split up into two groups by  researcher: a control group and an experimental group, which was assigned a number of five, numbering (5), and they constitute (63%) of  total community. This was done by drawing lots, as  investigator came to  conclusion that  suggested workouts have an effect in developing  skill of crushing in some biomechanical variables (angular velocity of  striking arm, shoulder angle now of striking, instantaneous velocity of  ball’s exit, and torso angle at  moment of striking).

Abstract

Background. Due to the fact that these are the player's own position changes, its important to work on improving these skills whether it be starting them or making sure we achieve those top levels of performance achievable. This is what the game is based on, along with a lot of basic technical skills — the player must move purposefully and variationally in as little time and with as little effort as possible. It also allows the player to toggle back and forth between offensive and defensive tasks. Knowledge of his work is part of success and part greatness. Objectives. The objective of the study is to develop training programs that can enhance agility and skill performance of junior volleyball players and determine how exercises enables junior volleyball players to increase their agility and skill performance. Method. By the trial method, the researcher had established comparable groups that were appropriate for the situation's kind. The study group consisted of players from Babylon Sports Club participating in the Iraqi Junior Volleyball League Championship for the period of 2024–2025. The participants were divided into two groups: The experimental group used workout sessions to increase speed and skill for hitting the volleyball, while the control group did not perform anything. This experimental group consisted of six junior volleyball players in addition to the team trainer. Results. This indicates that agility training improved performance of the skills. The researcher believes that it was the players' adherence to a standardized science-based training program that improved their performance on skill. Performance level indicates that this results in physical improvements and leads to the progress of volleyball-specific physical abilities. Conclusion. The study concluded that the recommended exercises have an effect in exercise volleyball spiking skills and agility skills volleyball spiking.
