IMPACT OF COMPETITIVE ACTIVITY ON THE CARDIOVASCULAR SYSTEM OF YOUNG SKIERS WITH NORMOTONIC TYPE OF AUTONOMIC RESPONSE
We analyzed changes of the hemodynamic parameters in young skiers with normotonic type of autonomic response during the competitive period. Young skiers aged 10-11 years underwent cardiography (with spectral and temporal analysis of heart rate variability) and the assessment of blood circulation parameters using computational and instrumental methods. We found that competitive activity stimulates unequal increase of functional reserves in the organism of young skiers, which depends on the stability of the autonomic nervous system.
