THE ROLE OF SPORTS ACTIVITY DRIVING FORCE AND BODY TENSION IN ACHIEVING SPORTS RESULTS

The purpose: to study the role of the driving force of sports behavior and the tension of the body's regulatory systems in achieving sports results. 

Organization and research methods. Free-divers, basketball players and athletes’ driving force of the sports behavior was measured. Then all athletes rotated the pedals of the bicycle ergometer to the limit of their physical capabilities with simultaneous intermittent breath delays from 20 to 60 seconds. The body tension was assessed by the value of the standard deviation of the duration of cardiac cycles.

Research results. In all three groups of athletes, the driving force of behavior (62.4, 59.6 and 50.0%) was more than their result of sports activity (52.5, 31.3 and 20.3%). The body tension in the pre-start state was sufficient for sports activity in all three groups of athletes (64.8, 74.7 and 63.9%). During sports activity, the body tension decreased to 35.9% in free-divers, did not change in basketball players and increased to 78.9% in athletes. 

Conclusion. The athletes' psychophysiological capabilities allowed to achieve better results. Free-divers had an increased parasympathetic nervous system tone, basketball players had a preserved vagosympathetic balance, and athletes had an increased sympathetic nervous system tone.
