摘要
In recent years, EEG-neurofeedback training (EEG-NFB) has been increasingly used to optimize various brain functions. Better perfoimance in various activities was also reported after relaxation trainings, another popular method in therapeutic practice. Both these methods are used as a part of professional coaching in sports training centers. In the present study, we aimed to evaluate the impact of such holistic training on physiological (EEG) and behavioral measures on semi-professional athletes. EEG-NFB paradigm was intended for amplification of the amplitudes of SAM (12-15 Hz) and betal (13-20 Hz) bands and simultaneous redaction of the amplitude of theta (4-7.5 Hz) and beta2 (20-30 Hz). Participation in NFB sessions was accompanied with self-administration of relaxing, audio-visual stimulation after each daily athletic training session.
The training program resulted in the increase of alpha and betal power of trained participants when assessed in rest with eyes-closed. In eyes - open state, participants of the trained group maintained the same level in all frequency bands, in opposite to the control subjects, whose power decreased in the second measurement in betal band when compared to the first one. The trained group exhibited greater reduction of reaction times in a test-of visual attention than the control group and showed improvement in several performance measures of Kraepeli-n's work-curve, used to evaluate speed, effectiveness and work accuracy. Together, these results present initial support for the use of holistic, rteurophysiological training in sports workout.
