| Abstrakt: | The optimal psychophysiological state reflects a high level of adaptation, physical and psychological fitness of athletes for the effective implementation of sports and training activity. The biofeedback technology, based on the principles of biofeedback, allows one to master the skills of regulating the psychophysiological state according to the selected parameters for controlling the physiological function of the body. There is insufficient data on application of neurofeedback of the beta rhythm for regulation of the psychophysiological state in conditions of complex sports activity. Objective: To examine the effect of biofeedback training on the beta rhythm of the brain on the level of anxiety and the endogenous time estimation of athletes, depending on the nature of motor activity. Material and Methods: 1020 young men aged 18-21 years old were studied. The biofeedback training on the beta rhythm of the brain was carried out with active wakefulness and open eyes, with a bipolar installation of electrodes in the Fz-Cz lead and a free electrode on the earlobe. The level of anxiety of athletes was identified with the Ch. Spielberger questionnaire [1]. The endogenous time estimation was carried out according to the «Individual minute» test (according to F. Halberg) [2]. Results: The biofeedback training contributed to multidirectional changes in the studied psychophysiological indicators, depending on the nature of the motor activity of athletes. After the training, in the group of cyclic sports athletes, there was a decrease in anxiety, remaining in the range of values of a high level, which may reflect the processes of fatigue or under-recovery. Representatives of speed-strength sports had a decrease in anxiety with varying values in the range of a moderate level, which reflects the achievement of a generally comfortable psychophysiological state. In the group of athletes of single combat sports, accelerated perception of time was noted, accompanied by anxiety, fussiness, decreased attention span and increased stress. Athletes of team sports had a unidirectional tendency of increasing anxiety with a variation of values in the range of moderate stress levels, which may be associated with an adaptive transition to a new level of the body functioning after the training. Conclusion: The use of the biofeedback training on the beta rhythm of the brain in the practice of sports and rehabilitation medicine requires a thorough and detailed study of its effect on various parameters of the psychophysiological state of athletes. The development of methods for the differential application of the method, taking into account the polymetric characteristics of the initial state, type of sports activity and other factors, calls for special attention. |
