[The role of aerobic capacity and efficiency in determining the intensity of training therapy and physical rehabilitation in chronic ischemic heart disease].

A number of values based on ergospirography results determining and limiting physical aerobic working capacity were studied by way of comparison in 35 patients with angina of effort with different threshold oxygen consumption. It was first established that aerobic capacities in chronic CHD were characterized not only by the power or cardiorespiratory productivity but also by the efficacy of the oxygen mechanism of energy production and realization of aerobic potentialities unrelated to one another. The informative value and usefulness of values of the threshold of anaerobic metabolism for determination of the optimum intensity of exercise therapy were revealed for expanding the aerobic capacities of patients with chronic CHD.
