The Effect of Eight Weeks of Incremental Endurance Training on The Levels of Matrix Metalloproteinase-1 (MMP1) and Thrombosponidine-1 (TSP1) in the Rats, Induced by Myocardial Infarction by Isoproterenol.
Background and AimExtensive prevalence of myocardial infraction, and an increase of 36% in total deaths due to it by 2020, and attention to the causes and methods of alternative therapy is very important. There are different ways in treating these patients that endurance training is one of them. The aim of this study was to evaluate the effect of 8 weeks of incremental endurance training on serum levels of TSP-1 and MMP-1 in male Wistar rats with myocardial infarction.
Materials and MethodsIn this controled experimental study with control group, 20 rats weighing 230 ±30 g (8-week-old) were randomly divided into incremental endurance training and control, after induction of infarction with Isoproteronol (150 mg/kg). The training group performed an 8-week training session (3 sessions a week, for 20 to 50 minutes at 12 to 18 meters per minute).Then, 24 hours later, the venous blood sample was collected to evaluate serum concentrations of TSP-1 and MMP-1 and transferred to the laboratory. Independent t-test was used to analyze the data at a significant level of p <0.05 to Graphed Pad software.
Ethical ConsiderationsThis study with research ethics code IR.IAU.ARAK.REC.1397.007 was approved in Research Ethics Committee of Islamic Azad University, Arak branch, Iran.
FindingsThe results showed that endurance training significantly increased serum MMP1 levels (p = 0.048) in rats with myocardial infraction, while there was no significant effect (p = 0.092) on the exercise program in serum TSP-1 levels.
Conclusionthe result of this study suggests that increasing endurance training may increase MMP-1 in rats with myocardial infraction, which can play an important role in angiogenesis and replacement of capillaries.
