Abstract:
Two animal models were established in this experiment to investigate the relationships between muscle damage and plasma activity of CK and its isoenzymes of rats after different modes of exercise.Model 1: untrained male Sprague-Dawley rats undertook swimming exercise of three different durations:25 minutes, 50 minutes and exhaustion. Model 2:after 2-week′s downhill running, male Wister rats undertook a 3-graded downhill running finally. Plasma and soleus muscle samples were taken to observe the changes of CK, CK isoenzymes and muscle damage. The linear correlation coefficients between plasma CK activity, CK-MM% and the Z-band abnormity rate of soleus muscle immediately after swimming in model 1 were 0.875 ( P
