Abstract:
Background

 The creatine phosphokinase-MB (CPK-MB) isoenzyme level is useful in determining the myocardial infarction (MI) extent and time. Evidence indicates the possible effect of exercise training on reducing the amount of CPK-MB, but the proper intensity of exercise is still unclear.

Objectives

 In this study the effect of intensity of exercise training on creatinine kinas after a myocardial infarction in plasma levels of male Wistar rats was comparing.

Methods

 Thirty two male Wistar rats at 10 weeks of age were divided in to four groups [low (N = 8), moderate (N = 8), and high (N = 8) intensity interval training and a control (N = 8) group (no exercise)]. Six weeks later, rats became MI patients through surgery. CPK-MB plasma levels were investigated before training, immediately after training for six weeks as well as 12 hours after MI. The data were analyzed by ANOVA with repeated measure and Tukey (α ≥ 0.05).

Results

 The results showed that changes in CK enzyme at 12 hours after MI in LIIT (113.88 ± 19.25), MIIT (135.88 ± 35.58) and HIIT (105.75 ± 19.05) were statistically significant compared to the control group (124.62 ± 23.41) only in 12 hours after MI and this reduction in the low-intensity interval training group was significant than the other two groups (P = 0.0001).

Conclusions

 In this study, six weeks of interval training with each intensity was likely to make cardiac cells resistant to necrosis resulting in low levels of the CPK-MB enzyme compared to the control group after the myocardial infarction event.
