1. Evaluation of cardiopulmonary endurance: 50-meter running is a short-distance and high-intensity exercise, which requires high cardiopulmonary endurance. In the 50-meter running test, candidates need to complete the running task within the specified time, which can evaluate the level of cardiopulmonary endurance. Cardiopulmonary endurance refers to the ability of cardiovascular system and respiratory system to work together during exercise, which is one of the important indexes to evaluate physical health.
2. Evaluation of muscle explosive power: 50-meter running needs rapid acceleration and rapid stop in a short time, which requires high muscle explosive power. Muscle explosive force refers to the ability of muscle to produce maximum strength in a short time, which is one of the important indexes in exercise.
3. Evaluation of speed and coordination: The 50-meter running test requires candidates to complete running tasks within a specified time, which requires high speed and coordination. Speed and coordination is one of the important indexes in sports, which can reflect the physical coordination and sports skill level of the subjects.
