Objective of the study was to analyze the dynamics changes in the cardiovascular system with vestibular irritation among representatives of game sports. Methods and structure of the study. Sampled for the study were 63 males (23.6±1.4 years), second-class athletes or higher level from team sports, with at least three years of sports experience: hockey (n=21), volleyball (n=22), football (n=20). The Control Group (n=19) was made of the apparently healthy students (22.1±0.9 years old), who performed significant muscle loads only during the university physical education classes. V.I. Voyachek standard turning test to determine functional changes in the cardiovascular system under the influence of vestibular irritation. The cardiovascular response was evaluated by recording the heart rate and blood pressure before and after the turning test (standard option - 5 rotations in 10 s). To include a large number of receptors of the semi-circular canals of the vestibular system, the subjects were asked to rotate turning their heads in both directions (5 rotations in 10 s). To increase the size of the rotation on the vestibular system, the duration of V.I. Voyachek standard turning test was doubled (10 rotations in 20 s). Results and conclusion. According to the findings, the cardiovascular rate in the hockey players, volleyball players, and footballers was within the normal limits: 64.2±0.59; 61.0±0.75 and 59.6±0.59 bpm, respectively. In Control Group, this rate was also within the norm, though slightly higher than in EG (70.2±0.93 bpm). The subjects` heart rate in response to the vestibular load increased in both groups. Regular team sports driven training activities increase the level of adaptation to vestibular loads and train the muscle of the heart. In different game sports, motor actions contribute to the formation of a pronounced heart reaction to the turning test with a change in the head position in space. The physiological shifts in the myocardium were seen in the heart rate changes and were most biologically advantageous for the footballers, slightly surpassing those in the volleyball and hockey players. In team sports, the vascular tone and associated blood pressure level do not seem to be clearly related to the specific movements.
