Introduction. The lag of Russian sprinters from leading foreign athletes in such prestigious athletics disciplines as running 100, 200 m and 4x100 m relay race necessitates the search for ways to improve the effectiveness of the training process. The purpose of the study: to identify the role of speed endurance, as one of the main components of the result in sprint running, in the development of sportsmanship in athletes of various qualifications. The methodology and organization of the study. Methods of theoretical analysis, synthesis and generalization of information, and mathematical statistics were used. The results of 252 short-distance runners in the 100 and 200 m races were analyzed. The indicator of speed endurance was also determined for athletes according to the generally accepted formula by N.G. Ozolin. The data of the 12 strongest sprinters in Russia was analyzed. For comparison with them, the results in the 100 and 200 m races of the world's strongest sprinters were also analyzed. Research results and discussion. It has been established that the speed endurance, starting from a value of 1.12 s for third-graders, improves to 0.21 s for masters of sports. An analysis of the 12 best results of Russian sprinters for 2022 showed that only two of them have a speed endurance index above the level of a master of sports. A corresponding analysis of the data of 13 Olympic champions made it possible to establish that all of them have values of the speed endurance index, starting from 0.16 s and reaching even negative values - V. Borzov (-0.8 s), U. Bolt (-0.08). Conclusions. Underestimation of the contribution of speed endurance to the progress of sports results in short-distance running occurs in the training of Russian runners, starting from the III sports category and up to the master of sports
