SUPERNORMAL DIASTOLIC LEFT VENTRICULAR FUNCTION AS A FUNCTIONAL INDICATOR OF THE ATHLETE’S HEART
Abstract
Abstract. Aim. The paper aims to identify and analyze hemodynamic parameters of the athlete’s heart as markers of adaptation to aerobic and anaerobic exercise in skilled athletes. Materials and methods. The following methods and tests were used in the course of the study: somatoscopy (physical development), Doppler echo (morphometric and hemodynamic measurements of the athlete’s heart), Cooper test (general performance), 300-m running performance (special performance and glycolytic capacity under anaerobic conditions). Results. The paper describes the change of transmitral flow pattern (the so-called supernormal type) in the diastolic period of cardiac adaptation to aerobic and anaerobic exercise with respect to muscular metabolism and morphofunctional cardiac parameters in the form of normal left ventricular geometry. The relationships were found between running performance, morphometric and hemodynamic parameters in males aged 18–29 years (athletes and nonathletes). Conclusion. Hemodynamic parameters of transmitral flow reflect the level of cardiac adaptation to aerobic and anaerobic exercise in skilled athletes. At the same time, morphometric parameters should correspond to physiological norms.
