This research aims to identify the effect of anaerobic training on physical performance endurance and the concentration levels of some biochemical indicators in the blood, namely creatine kinase (CPK), lactate dehydrogenase (LDH), and lactic acid concentration, among players on the Iraqi national futsal team with mild intellectual disabilities. The research problem was the observation of a state of poor skill and physical performance, lack of concentration, and the appearance of signs of fatigue in the second half of official matches, indicating a weakness in the ability to endure performance. The researcher adopted a solution to this problem by developing an anaerobic training program during the special preparation period to determine the effect of anaerobic training on performance endurance and the aforementioned biochemical indicators. The expected results recommend the adoption of targeted anaerobic training, which contributes to improving and raising physical and skill efficiency by developing and improving the concentration of the enzymes under study, along with the concentration of lactic acid in players, and improving blood indicators related to performance endurance. This is closely related to these indicators, which have an impact on Select and know the players' levels through it.
