Abstract
Aim. The purpose of the study is to conduct a comparative analysis of the effectiveness of physical aerobic training in the mode of interval and constant loads in patients who have had a myocardial infarction with subsequent percutaneous coronary intervention. Materials and methods. 35 patients aged from 46 to 67 years old were examined in the process of passing a 3-week course of physical rehabilitation in a day hospital. Of these, 18 people (group 1) performed daily training on cardiovascular machines in the mode of interval loads, 17 people (group 2) - in the mode of moderate loads with constant intensity. Results. When conducting physical training in different training regimens, both groups of patients showed an improvement in exercise tolerance. At the same time, the interval training as compared to the constant intensity training provided a more pronounced training effect on the cardiorespiratory system due to high-intensity loading phases and at the same time a low level of hemodynamic load due to the presence of relatively low-intensity phases. Conclusion. Interval training is preferred in patients who have had a myocardial infarction followed by percutaneous coronary intervention, due to their high efficacy and safety.
