Plasma creatine kinase (CK) and lactate dehydrogenase (LDH) concentrations in rats after eccentric exercise
Values are expressed as the mean ± SD (n = 8/group). The rats performed a graded treadmill run to fatigue on a customized rodent treadmill. The protocol consisted of having rats run upward at a speed of 25 cm/sec (0~2 weeks); 30 cm/sec (2~4 weeks) and 35 cm/sec (4~8 weeks). Blood samples were collected at 0 (before exercise) and at 30 min after exercise. *p < 0.05 (vs. EC).
