Aim. The article deals with studying the features of psychophysiological adaptation to physical load and the functional status of the cardiovascular system in badminton players. Materials and methods. The study was conducted in the premises of Dostoevsky Omsk State University during badminton training activities as a part of Omsk Higher Educational Establishments Spartakiadpreparation in September 2016 – May 2018. Fifteen students aged 18–19 years participated in the study on a voluntary basis. The study was conducted using the electronic surveys placed onhttps://onlinetestpad.com: the Spielberger state-trait anxiety inventory and the Well-Being, Activity, Mood test. To establish the maximum anaerobic capacity of the body, the Margaria testwas used. A Zeugner’s polychromatic rapid test was used for establishing the emotional background. Results. The analysis of the results obtained revealed that the highest heart rate values were registered during a long badminton rally and reached 190 bpm. During pauses heart rate decreased to 160 bpm. A badminton rally of 4–6 seconds allowed maintaining the heart rate at 160 bpm.If followed by pauses heart rate decreased to 130 bpm. Assessing the mechanisms of psychophysiological adaptation and studying the subjective characteristics of situational and personal anxiety, well-being, performance and emotional background before and after training allow identifying athletes with different adaptation capacities and increasing their physical performance. Conclusion. The analysis of the results obtained demonstrated changes in psychophysiological adaptation and the functional status of the cardiovascular system. It was also revealed that physical load provoked stress in the mechanisms of psychophysiological adaptation.

Background. The objective of this study was to establish how accurately elite athletes carried out the task of a coach to perform an exercise at a given intensity. Methods. Cardiovascular indices were registered and analysed during a two-step research process. Two groups including six well-trained long-distance runners and 21 healthy non-athletes performed graded stress exercise up to the inability to continue the task. Runners took part in the second study in which heart rate and running pace were recorded during an aerobic training session. Results. Research findings showed that athletes demonstrated higher physical performance, but the maximum heart rate values achieved in the last fatigue phase did not differ significantly between the groups. No ischemic events were observed in elite athlete group during the entire physical test. Relatively stable heart rate indices in the maximal physical load step were observed in both groups, but heart rate indices were significantly lower during all physical load steps in the group of elite runners. Conclusions. Elite athletes carried out the coach’s task only in the first phase of running and further modified the task by maintaining the stability of the cardiovascular system

Research background and hypothesis. Sports dances at the contest intensity demand great athletic fitness and functional capacity from dancers We still lack research about changes in the heart rate in the group of juvenile dancers’ while dancing  Standard and Latin American dances. The present study aims at verifying the hypothesis that while juvenile dancers dancing contest programmes, the heart rate is changeable and can reach to 160–190 beats/min and above, sports dancers consume much energy.Research aim was to investigate changes in the heart rate and energy consumption in the group of juvenile dancers while dancing Standard and Latin American dances. Research methods. The research participants were 16 dancers (8 girls and 8 boys). The age of girls was 9.88 (0.83) years, and that of boys – 9.86 (1.07) years. We established changes in the heart rate dancing Standard and Latin American dances. During continuous dancing we registered the heart rate using “Polar S 610” Heart Rate Monitor (Finland) with computer data registering system. According to the indices received from the heart rate monitor we calculated the average, maximal and minimal heart rate values and energy consumption (kcal) during the period of sports dancing programme. Research results. The data of HR analysis showed that during a 10-min model practice session dancing Standard and Latin American dances, the heart rate which remains the longest is 160–190 beats/min. During Latin American dances, energy outlay for girls was greater than that for boys (p < 0.05), but lower compared to those when the girls danced the Standard programme. Discussion and conclusions. In contest programmes of sports dancing, physical loads are of changing intensities and thus they have a big impact on the cardiovascular system of young dancers. At the threshold of anaerobic intensity, some moments of the dance are performed at greater intensity then the anaerobic threshold, and even critical intensity limit is reached.Keywords Standard dances, Latin American dances, intensity of physical load, heart rate, energy consumption.

The article is devoted to studying the condition of central and autonomic nervous systems in the recovery period after the refusal of intensive physical load. The study involved 25 young men aged 18, 4 ± 0, 3 year. Each of them, it was offered a test with increasing in intensity step-dosed physical load on the cycle ergometer. &#34;Sports Art 5005&#34; ergometer was used for load testing and the testing itself was conducted under ECG and EEG control. A spectral analysis of ECG and analysis of heart rate variability were conducted. The heart rate, Kerdo index, stroke volume, cardiac output blood flow were calculated. The full EEG spectral power and spectral powers of separate rhythms were evaluated. Blood pressure was measured in the «background» status, at the moment of failure to take the load and after the recovery. The authors evaluated the level of self-feeling and fixed subjective complaints. It is shown, that at the time of failure of intense load subjects reach of the limit of their physical capacity level, which is reflected in the increasing of sympathetic effects. It&#180;s marked in increase in heart rate and hemodynamic parameters. At time when the motoric program was stopped, the subjects were begun to the recovery. It was accompanied by a significant increase in spectral power of delta waves in the prefrontal and occipital cortex of the left and right hemispheres in the 1st minute of recovery. The appearance of delta waves was due to the increasing of inhibitory processes in the cerebral cortex as a result of fatigue and they have of defensive nature. The recovery process is characterized by significant reorganizations of vegetative regulation mechanisms. It was marked a sharp increase in spectral power of VLF -waves on the third minute of recovery and a reducing of heart rate variability to the 6-th minute of recovery. Thus, the recovery process after intense physical load is characterized by significant reorganizations in condition of central nervous system and autonomic nervous system.
