The purpose of this paper is to preparing special exercises to develop speed tolerance and blood electrolytes, and to complete the 800-meter run for young, and identify the effect of the use of exercises in endurance speed, blood electrolytes, and achievement of running 800 m for youth. The experimental approach was used with one group design with a pre and post-test due to its suitability to the nature of the research. The research community was determined from the runners of the youth clubs of Wasit Governorate by the intentional method, as the research community consisted of six runners representing the clubs (Kut, Al-Nahrain, Damok, Wasit, Al-Azza, Al-Mowafaqia), a player for each club. One of the most important results reached by the researcher is that: Speed endurance training according to the anaerobic system has an effective role in developing speed endurance as well as in electrolyte indicators, and use of gradation and ripple with high load has an effective role in developing the digital achievement of the sample. One of the most important recommendations recommended by the researchers is that: Ensuring the use of speed endurance exercises in a variety of distances in the 800-meter run and conducting research using high-intensity interval training on young men and boys.
