Functional state in young wrestlers

Actuality. The modern stage of sports science is characterized by the development of studies of adaptation processes in athletes during intensive physical and emotional competitive activity. The main problems in sports training are the control of functional state of athletes. Modern young sport characterized of healthy and sport orientations. Non adequate loads without taking into account the age-related characteristics of morpho-functional and psychophysiological development provoke of deterioration of mood and well-being. Wrestling has a great popularity among youth all over the world. The researches of morphological and functional properties, psychological diagnostics and preparedness of young wrestlers are presented. But there are lack criteria for the functional state of young wrestlers. Purpose was the study of functional state in young wrestlers. Methods of research Were examined 31 young wrestlers, members of the Sport Club in Kremenchuk (age 15.85+2.15). All athletes agreed in writing to those received for participation in research in accordance with the recommendations of the ethical standards of the Declaration of Helsinki. To assess the functional state, a "Fazagraf" cardiomonitor was used. HR, NN, SDNN, Stress Index were evaluated. Functional mobility and balance of the nervous process were studied using "Multipsychometry-05". "Statistica 10" package was used for statistical analysis. Findings and results According to study of heart rate variability we calculated the indicator of Stress Index. This is parameter indicates the ability of athletes to stress resistant. All of athletes were separated by Stress Index: with low level of tension of autonomic nervous system (17 persons) and with high level tension of autonomic nervous system (14 persons). Wrestlers with a high Stress Index have tachycardia. A decrease in the SDNN value in wrestlers with a higher level of Stress Index is associated with an increasing activation of the sympathetic tone. This result is associated with a high level of stress. The study of the balance of the nervous process revealed differences between the groups of athletes in all values According to the results obtained, wrestlers with a high level of Stress Index exhibit arousal of the nervous system. In wrestlers with a low level of Stress Index, the nervous system is characterized by a balance between the processes of arousal and inhibition. Thus, a high level of tension of the regulation of the autonomic system corresponds to the arousal of the nervous system. The results show the functional mobility of the nervous processes in young wrestlers with different levels of Stress Index. This obtained indicate a decrease in decision-making time in wrestlers with a high level of Stress Index. This is due to better decision-making abilities with increasing tension in the autonomic nervous system. The presence of significant differences in the parameter of impulsiveness between both groups indicates the predominance of uncontrolled movements in wrestlers with a high Stress Index. In fact, an increase in the tension of the autonomic regulatory system leads to stochastic, uncontrolled movements in young wrestlers. The revealed fact indicates the mechanisms of stress management, which increase the ability to optimize the functional state of wrestlers. Conclusions and recommendations The main topic of our study was the research of the functional state of young wrestlers. Functional state including some links that support the ability of athletes to the effectiveness of competitive activity. One of the important properties of athletes' preparedness is heart rate variability. No less impossible for development of results in wrestling is the psychophysiological state. Some links of the psychophysiological state of wrestlers contribute to the improvement of perception and processing of information from the external environment. An increase in the tension of autonomic regulation leads to a predominance of arousal. In wrestlers with a low level of Stress Index, the nervous system is characterized by a balance between the processes of arousal and inhibition. When studying the functional mobility of the nervous process, it was found that against the background of an increase in the Stress Index, additional uncontrolled movements are a mechanism for stimulating stress in young wrestlers.
