Orthostastic stability in the vegetative maintenance of the working ability of elite athletes
Orthostatic stability in the vegetative maintenance of the working capacity in elite athletes was studied on a group of 203 people, including 109 men and 94 women from two sports - volleyball (104 athletes) and rowing (99 athletes). A program and criteria for the evaluation of operational diagnostics of the functional state of the autonomic nervous system, including an orthoprobe with an assessment of heart rate, blood pressure, and ECG in conditions of monitoring training and precompetitive loads of the annual cycle of training were developed. The interrelation of the level of orthostatic stability in the vegetative maintenance of working capacity of volleyball players with the account of growth indicators and game role is revealed. In tall diabolic and central blocking volleyball players, the symptoms of disadaptation of the cardiovascular system in a reaction to orthostasis are more often diagnosed. In the group of athletes rowing, the relationship between the level of orthostatic resistance with age and sex was revealed: in young men and juniors, the symptoms of disadaptation often appear in response to orthostasis and to the maximum physical load on the rower ergometer “CONCEPT”. It was revealed that speed-strength loads of male oarsmen are more often reflected in the appearance of hypertension and hypertonic reaction in work to failure on a rowing ergometer. Prompt diagnosis of the orthostatic vegetative stability allows us to determine the early signs of cardiovascular overstrain and can be used as signal for correction of loads and recovery.
