[Relationship between the Parameters of Muscular and Cardiovascular Systems in Graded Exercise Testing in Subjects Doing Regular Exercises and Sports].
We analyzed the relationship between EMG and ECG parameters during graded step-dosed exercises with the use of bicycle ergometer in subjects doing regular exercises and sports. We observed the dynamics of EMG and ECG parameters in graded exercise testing. During physical activity of low intensity, muscular effort is mainly due to an increase in the heart rate; during activity of high intensity, the electrophysiological processes of the whole myocardium are involved. The interrelation of the parameters of muscular and cardiovascular systems was proved to increase with the intensity of physical activity.
