The Effect of Muscle Balance Training on Some Biomechanical Indicators of the Smash Skill in Youth Volleyball

Abstract

The importance of this research lies in highlighting the improvement of muscular efficiency in female badminton players, which manifests itself in enhanced technical and physical performance. Improving balance in body muscle strength helps players perform better in the smash skill and achieve better biomechanical indicators. This is achieved through a proposed approach to developing balanced muscular strength and bringing it to an appropriate level. Regarding the research problem, the researchers summarized the study's problem as the lack of ability to control force exertion at the required level, and the inability to suppress that force, stop it from being exerted, or direct it to specific points in the motor pathway for the smash skill. This is directly caused by a lack of attention to developing strength in a balanced manner between the working muscles, the auxiliary muscles, and the opposing muscles responsible for performance. The research objectives were to conduct muscle balance training based on exciton contraction for youth volleyball players, as well as to identify the effect of muscle balance training on some biomechanical indicators of the smash in volleyball for the research group, as well as to identify the impact of muscle balance training on the values of some biomechanical indicators of the smash in volleyball. On the differences in the values of some biokinematic variables of the crushing volleyball for a group. As for the research method, the researchers used the experimental method, with a single experimental group design. As for the research sample, (6) young players from Al-Furat Sports Club were chosen in volleyball deliberately in order to implement the study and achieve its objectives. The values of the skewness coefficients were all limited between (1-1+). This indicates the homogeneity of the individuals of the research sample in the research variables. As for the most important conclusions, they were that whenever there was an ideal mixture for the training load when applying muscle balance exercises according to the percentage of maximum intensity of the capacity of each part of the body, it is considered a constructive and preventive training to avoid the occurrence of an imbalance in muscle strength during special preparation periods                                           .
