Patterns of physiological reactions to standardized cardiorespiratory load as markers of age-related changes

The aging process is associated with a decrease in cardiorespiratory endurance. The profile of changes in hemodynamic parameters, respiratory and metabolic profile during cardiopulmonary exercise testing in the elderly can identify patients with subclinical forms of diseases. It is necessary to develop a standardized approach to the interpretation of parameters that can serve as diagnostic signs of an abnormal response of physiological parameters to physical activity and have optimal prognostic and differential diagnostic value.
