BICYCLE EXERCISE EFFECTS ON CENTRAL HEMODYNAMICS IN POSTMYOCARDIAL INFARCTION PATIENTS ON SANATORIUM TREATMENT

Aim. To study central hemodynamics response to bicycle exercise with o ptimal pedalling rate (OPR) and in free-choice regimen of pedalling as regards the initial pedalling rate in postmyocardial infarction (PMI) patients on sanatorium treatment. Materials and methods, Bicycle ergo metry and tetrapolar rheography examinations were performed in 124 PMI male patients. Bicycle exercise was carried oat in three regimens: a) optimal pedalling rate (1), b) muscular load chosen by the patient at the first training kept further for daily training (2), c) free-choic e daily toad (3). Results. In OPR 30 and 45 rpm, patients on regimen 3 improved their myocardial contractility both at rest and exercise. In OPR 60 rpm, exercise in regimen 1 was more effective. Regimen 2 was n ot effective. Conclusion. Hemodynamic effects were most pronounced (im proved myocardial contractility in move effective cardiac performance) in the regimen of OPR 60 rpm.
