Purpose: Our study aimed at determining and comparing the mechanism of cardiovascular protection variables in moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT) in patients with stable coronary heart disease (CHD) after coronary stenting.
Participants and Methods: This experimental study used the same subject and cross-over design, involving eleven stable CHD patients after coronary stenting. These were randomly divided into two groups; MICT for 29 minutes at 50– 60% heart rate reserve and HIIT with 4x4 minute intervals at 60– 80% heart rate reserve, each followed by three minutes of active recovery at 40– 50% heart rate reserve. These were conducted three times a week for two weeks. The participants’ levels of adrenaline, noradrenaline, endothelial nitric oxide synthase (eNOS), extracellular superoxide dismutase (EC-SOD) activity assayed, and flow-mediated dilatation (FMD) were examined before and after treatments were completed.
Results: The HIIT significantly increased the levels of noradrenaline and eNOS compared with MICT (p< 0.05). Also, HIIT was better in maintaining EC-SOD activity and FMD compared with MICT (p< 0.05). Through the noradrenalin pathway, HIIT had a direct and significant effect on eNOS and FMD (p< 0.05) but MICT, through the noradrenaline pathways, had a direct and significant effect on eNOS (p< 0.05), and through the EC-SOD activity pathways had a direct and significant effect on FMD (p< 0.05). MICT reduced EC-SOD activity and also decreased the FMD value.
Conclusion: HIIT is superior to MICT in increasing cardiovascular protection by increasing the concentrations of noradrenalin and eNOS, maintaining EC-SOD activity, and FMD in stable CHD patients after coronary stenting.
