运动训练中， Sauders曾指出，肌酸激酶 (CK)是肌肉应激最敏感的指标，可用于机能评定。然而 CK同工程酶受应激影响下变化特点是什么，报道尚少。本文旨在以田径运动员为研究对象，观察和比较不同负荷，调整恢复时总 CK、 CK－ MM、 CK－ MB的变化特点，及运动能力与酶活性变化 During exercise training, Sauders pointed out that creatine kinase (CK) is the most sensitive indicator of muscle stress and can be used for functional assessment. However, CK with engineering enzymes under the influence of stress changes in what is characterized by little. This article aims to track and field athletes as the research object, observe and compare different load, adjust the recovery of total CK, CK-MM, CK-MB changes, and exercise capacity and enzyme activity changes
