Mikhalyuk E. Diagnostics of the boundary and pathological conditions on the terminal physical exertion in the Olympic and professional sport

The thesis is dedicated to improving the diagnostics methods of the boundary and pathological conditions on the terminal physical exertion in the Olympic and professional sport in order to prevent the harmful influence of overexertion on the sportsment's cardiovascular system. We have studied the influence of elevated training loads on HRV indices, central hemodynamics and physical efficiency in high class sportsmens of acycling and cycling kinds of sport and changes this parameters of sportsmen depending on the qualification level and sex have been analysed. It has been proved that sportsmen's skill improving, irrespective of the kind of sport, is accompanied by forming hypokinetic type of central hemodynamics which is associated with the increase of activity vegetative nervous system parasympathetic section, and relative indices of physical efficiency in men and women come nearer.The method of complex diagnostics, echocardiographyc and biochemical (troponin I) criteria of metabolic cardiomyopathy inconsequence of chronic physical overexertion in sportsmen has been devised. Diagnostic sensitivity of stress Echo-tests - submaximum test PWC170 and on the threshold of individual tolerance with twin troponines I in verification of the cardiopathy coincides and amounts 25,9 % and 25,0 % respectively.
