Indices of functional condition for central nervous system, sympathetic nervous and cardiovascular systems in terms of qualifying grades for swimmers-sprinters

The main aim of the work was to determine the diagnostic significance of physiological criteria of functional condition for central nervous system, sympathetic nervous and cardiovascular systems from the point of qualifying grades (Master of Sport and Candidate Master of Sport) for athletes specializing in swimming for short-distances. According to the obtained data the important physiological parameters from total analyzed complex are the emotional stability as for hardware-software device "Origins of Health", power of slow first-order waves as for variation pulsometry, relation R/T in V4-V6 as for electrocardiography and diameter of aortic root as for Doppler echocardiography.
