Objective of the study was to assess the hemodynamic status and left ventricle function in athletes trained on a regular basis. Methods and structure of the study. Subject to the study were 22 male athletes (12 first-rank athletes and 10 Candidate Masters of Sport of Russia) aged 18-23 years. All the track-and-field athletes taken under observation were trained on a daily basis. The subjects` total years in track-and-field athletics equaled 4. The Control Group was made of 32 apparently healthy volunteer university students aged 18-23 years, who were subjected to physical loads at the academic physical education classes only. Results and Conclusions. It is believed that the high myocardial relaxation velocity is common to regularly trained individuals. The weight of evidence suggests that the maximum rate of the left ventricular relaxation in the posterior wall, as a value that indirectly characterizes the time of development of this process during the diastole. Regular physical loads affect the hemodynamic status and heart contractile function of track-and-field athletes. Long-term track-and-field sports training is accompanied by the growth of the left ventricular mass with the absence of its dilation and preservation of the central hemodynamics and cardiac functionality. Under the influence of the long-term track-and-field sports training, there is a tendency to a functionally advantageous increase in the maximum velocity of relaxation of the left ventricular posterior wall.
