as well as the conditions for comprehensive development in all fields, including sports. Nowadays, as the level of, sports expertise has developed significantly, the demands placed on instructors are increasingly high. To achieve good results in middle-distance running, instructors must employ a variety of exercises and competition strategies, among which specialized endurance is a crucial factor that determines performance. If a middle-distance runner does not have good specialized endurance their ability to resist fatigue in extreme conditions will weaken, preventing them from completing the exercises set by the instructor and leading to a decline in competition results. Therefore, enhancing specialized endurance for the 23rd cohort of middle-distance runners is essential and indispensable. To achieve that goal and idea our Party and State focus on and identify the human factor as always being the objective and driving force in the cause of building and developing the country. The strategy emphasizes the need to develop physical education and sports in schools in the armed forces and among the general public, especially focusing on developing high-performance sports and professional sports. Based on this requirement, the author has chosen the topic: “Research on selecting exercises to develop specialized endurance for students of the Physical Education Department, class 23 at Dong Thap University.”
