The effect of plyometric exercises according to the difficulty of the training unit to develop the reaction speed of the limbs and some basic skills in volleyball for advanced players

Abstract

The importance of the research comes from raising the level of reaction speed of the limbs for advanced volleyball players after using plyometric exercises and regulating the load according to the difficulty of the training unit. Thus, we may show that plyometric exercises help in developing other qualities and not just muscle strength, as it deals with additional weight exercises and can be applied in exercises that depend on speed and response speed. The research problem was: The response speed of volleyball players is important and essential in performing skills in attack and defense, which requires developing it or developing the working muscles of the limbs by building the required strength and speed and according to sudden situations that work to raise the response speed using the correct exercises and the regulated load according to the difficulty of the training units. The most important objectives were: To know the effect of plyometric exercises according to the difficulty of the training unit to develop the reaction speed of the limbs and the skill performance of the applicants. The most important conclusions were: Plyometric exercises according to the difficulty of the training unit helped in developing the reaction speed of the limbs and some basic skills of the applicants. The researcher recommended: Adopting plyometric exercises according to the difficulty of the training unit because they helped in developing the reaction speed of the limbs and the skill performance of the applicants.
