Abstract
Ballistic training is one of the training methods to develop speed and strength through the full range of motion. The performance of ballistic training depends on the theory of using resistance proportional to the strength and speed of the elasticity of the muscles so that the goal of the training program is achieved by developing maximum muscular ability as a means of developing the mechanical effectiveness of the working muscles to reach a better level. In motor performance, from the above, the importance of the research lies in the researchers’ endeavour to use ballistic training to develop some biomechanical variables that constitute an essential essence for the technical performance of the skill. The ace serves in volleyball, in addition to achieving accuracy in performance, by developing the strength of the legs to reach the highest possible height to hit the ball, thus achieving the best performance in the game of volleyball. As for the problem of research, through following up on developments in the game of volleyball in general and the development taking place in the skill of the ace serve in particular at the global, Arab and local levels, and because of its impact in deciding the outcome of the match. Through the observation of the researchers, they noticed that the technical level of this skill is not consistent with the development taking place and that there is weakness and significant fluctuation among young players in the accuracy of performance. The researchers attribute this weakness to not taking care of improving the skill aspect in accordance with the foundations and rules of the game, and it is considered one of the most critical problems facing those in charge of the training process. Hence, the researchers decided to study this problem by preparing ballistic exercises to develop some bio-kinematic variables, thus developing the volleyball ace skill. The objectives of the research are to prepare ballistic exercises to develop some Biomechanical variables and the accuracy of the ace serve in volleyball for youth and identify the statistical differences between the pre-and post-tests of the control and experimental groups for some biomechanical variables and the accuracy of the ace serve in volleyball for youth, and identifying the statistical differences between Post-tests for the control and experimental groups for some biomechanical variables and the accuracy of the smash serve in volleyball for youth. The researchers used the experimental method by designing two equal control and experimental groups as it is the most appropriate for such a study. As for the research community and sample, the researchers determined the research community in an intentional way and they represent the players of the Specialized Volleyball Center in the district. Al-Shatra in Dhi Qa Governorate (youth category) aged (16-18) years and numbering (15) players, where (5) players were selected from the research community and outside the sample To conduct the exploratory experiment and (10) players representing the research sample, the sample percentage was (66.66%) from the original population, and the most important conclusions were the development of the level of accuracy of the aces skill among the members of the research sample through the differences that appeared in the results of the post-test and in favor of the experimental group.
