Abstract
This paper studies the relationship between EMG and ECG parameters during intensified stepdosed physical exercises with the use of a bicycle ergometer in subjects doing regular exercises and sports. The dynamics of changes in EMG and ECG parameters is observed in subjects during a step-dosed intensification of exercises. Specifically, if physical activity is not intense, muscular effort is mainly due to an increase in the heart rate; if it is highly intense, the electrophysiological processes of the whole myocardium are involved. The interrelation of the parameters of the muscular and cardiovascular systems is shown to increase with the intensity of physical activity.
