Eccentric stretching exercises are of great importance to muscles which is used in the allocate activity, as the development of strength, speed, and accuracy in performance and reaching max desired are import to achieve to the high level, as nature of the spike performance requires the player to smooth the motor performance and the speed of reaction High and fast explosive ability of the muscles of the legs and arms and neuromuscular compatibility. The importance of the research lies in the fact that strength training by eccentric extension is one of the modern training methods that contribute to the development of the accuracy index because of its obvious importance in developing the spike hit in the volleyball game.
As for the research problem, it is that some coaches did not resort to such modern and advanced methods in the field of training, which negatively affected the technical performance of the players in the skill of overwhelming , which requires great physical effort and for longer periods of time during the game. Therefore, the researcher decided to study this problem by developing decentralized strength training exercises that would develop the strength that the player needs in order to correct it and reach the best technical performance in the indicator of the accuracy of the spike hit with volleyball.
The research objectives were: Preparing strength exercises by eccentric stretching to influence the accuracy index of the spike skill of youth volleyball. And to identify the effect of strength training by decentralized stretching in the indicator of the accuracy of the spike skill of volleyball for youth. And to identify the preference of the two groups (experimental and control) in the studied research variables for the skill of spike volleyball for young people.
