Adaptability of cardiorespiratory system in normotensive and hypotensive female students with different impact of the autonomic nervous system subdivisions

Abstract

It was carried out the analysis of the body adaptability in the situation of training loads stress in students with normotension and hypotension and predominance of different types of autonomic nervous system regulatory influence on the cardiorespiratory system. In 103 second-year female students of KNMU systolic, diastolic blood pressure, pulse pressure, heart rate were measured, the Kerdo index and the Robinson index were determined. Functional breathing tests with breathing delay on the inhalation (Stange) and on the exhalation (Genchi) were conducted. They are the indicators of the cardiorespiratory system functional state and sensitivity to a decrease of oxygen saturation in arterial blood (hypoxemia) and carbon dioxide increase in blood (hypercapnia). Psycho-emotional stress in second-year female students causes a deficiency in the body adaptation reserves. Formation of adaptating to learning stress is carried out at the limit of the functional capabilities of the body and may lead to a breakdown of adaptation
