[The characteristics of the intracardiac and systemic hemodynamics in young, healthy, untrained subjects during physical loading of moderate intensity].

Intracardial and systemic hemodynamics have been studied in 107 healthy men aged 18-24 years during their functional rest and physical loads of 60 Wt. The echocardiographic method with hard fixation of an echo sensor was applied. Normal values of the heart functional volumes, heart output, ino- and chronotropic activity, arterial pressure and myocardial energy exchange were determined during the functional rest and under physical loads.
