Abstract :
    Introduction Endurance is the ability to work at a certain intensity for a long period of time. Fatigue is one of the main factors that affect and limit the way you work. It can be said that an athlete s endurance is good when he does not get tired easily or when he is able to continue his activity in the stage of fatigue, that is, with the accumulation of lactic acid in his muscles (Ahmed et al., 2023; Bai et al., 2023). We divide endurance into two basic types: aerobic endurance Anaerobic endurance aerobic endurance Aerobic means movement or muscle activity with oxygen and aerobic endurance, in which the muscle uses oxygen to produce the energy needed for work or to produce power from stored resources. Aerobic exercises increase the heart s efficiency by increasing the volume of cavities and the ability of heart muscles to contract and thus increase the stroke volume. The energy needed to perform aerobic exercises is provided by glucose and fat, so to reduce aerobic exercise, it is the best type of exercise to reduce blood fat or body fat weight. If the athlete performs aerobic exercises and has good endurance, a lot of oxygen is transferred to the mitochondria of the muscle cells, thus aerobic metabolism is provided. , has a good aerobic capacity (Asghar et al.; Sarasht & Mahmoud, 2016; Kemri et al., 2023). Anaerobic endurance Anaerobic means lack of oxygen. Anaerobic endurance refers to the activity of energy devices that stimulate muscle activity by using their stored energy. Therefore, muscles cannot use oxygen during exercise or performing skills. Anaerobic endurance allows the athlete to tolerate the lactic acid produced in his body (Loprinzi et al., 2023). Two types of anaerobic endurance are considered: Endurance at speed Endurance in power Special endurance
