Abstract

The rapid development in achieving achievements and higher levels in various sports, whether in team or individual games, and that upgrading this level did not come from a vacuum, but science was and still is the basis for it, and accordingly, scientific research has tended towards the study of various sciences, including chemistry and physiology Sports and employing it to serve the science of sports training in order to raise the level of athletes in all sports because of this science of fundamental importance in developing and correcting training methods, and knowing the responses and adaptations that occur during the practice of sports activity, as knowing the biochemical changes that occur within the muscle cell to produce energy It is important for sports performance because it gives us an impression of the impact of the training method used, as well as the goal it achieves
