一、大学生运动员疲劳产生的原因1.肌肉的疲劳。在极量和近极量有氧强度练习时,产生疲劳的原因主要是氧运输系统工作能力的限制,致使工作肌供氧不足。主要能源是肌糖原和肝糖原的消耗。当激烈运动时,ATP和CP被大量消耗,肌糖原便在无氧条件下分解为乳酸参与供能。并在供能过程中在肌肉中产生乳酸,随着运动时间加 First, college athletes cause fatigue 1. Muscle fatigue. In extreme and near extreme aerobic strength practice, the main cause of fatigue is the ability of oxygen transport system limits, resulting in lack of oxygen in the work of muscle. The main energy is the consumption of muscle glycogen and glycogen. When intense exercise, ATP and CP are consumed in large quantities, muscle glycogen in the anaerobic conditions, decomposition of lactic acid involved in energy supply. And in the energy supply process in the production of lactic acid in the muscle, with exercise time plus
