Aim: Cardiovascular disease, due to its chronicity, often affects everyday activities of the individual and is the leading cause of death in the world. The purpose of this study was to investigate the effect of increasing endurance training on adjustment indicators Apoptosis is indicated in samples of patients with myocardial infarction.
Methodology: In this study, 20 Wistar rats aged 8-10 weeks with a mean weight of 230±30 for two groups of infarction control (Sed.MI) and infarction (Ex.MI). After induction of experimental myocardial infarction with two intraperitoneal isoproterenol injections at a dose of 150 mg/kg for 24 hours, the exercise group performed an endurance training protocol on the treadmill for eight weeks. Applying in the same conditions followed at least 24 hours after the last training session. To examine the significant changes in the levels of Caspase-3, Caspase-8 and Cytochrome-C, independent t-test was used in Graph Pad program.
Results: The results showed that serum levels of Caspase-8, cytochrome-C and Caspase 3 in Ex.MI group were higher than that of Sed.MI group. This increase was not significant in the cases of Caspase-3(p=0.65) and cytochrome-c (p=0.25) between Sed.MI and Ex.MI. But increase in caspase-8 values showed significant differences (p=0.04).
Conclusion: According to the results of this study, it seems that application of non-pharmacological strategies such as incremental endurance training cannot improve apoptosis rate in samples with myocardial infarction.
