Key-words: echocardiography, cardiac hypertrophy, aerobic capacity. Subject of the study. Endurance athletes' left ventricular morphofunction. Background. Whether left ventricular structure and function depend on the mode of the regularly performed endurance exercise is not conclusive. If it depended indeed, specialists in sports medicine, exercise physiologist, as well as athletic coaches would have a great possibility to design the architecture and predict the function of athletes' and possibly certain type of patients myocardium in response to aerobic exercise of different kind. Aim. To determine the peculiarities of the left ventricular structure and function between athletes of different endurance sports. Objectives: 1. To compare endurance athletes' left ventricular structure and function with that of healthy sedentaries. 2. To compare left ventricular structure between athletes of different endurance sports. 3. To compare left ventricular function between athletes of different endurance sports. Hypothesis. Distance-running- and swimming-induced haemodynamic overload triggers more substantial eccentric left ventricular remodelling when compared with canoe-kayak- and road-cycling-training. Regular paddling induces concentric left ventricular hypertrophic adaptation to similar extent as road cyclists' performed loads. Either mode of endurance exercise training has negative effect upon myocardial function. Conclusions. Myocardial mass is significantly greater in endurance... [to full text]
