IMPROVEMENT IN PEAK PERFORMANCE AS A RESULT OF THE INHIBITION OF BETA 2 BANDS (EEG) IN NEUROFEEDBACKEEG TRAINING IN MOTION.

Mikicin, Mirosław; Kowalczyk, Marek

Background: The motor cortex in humans is more active during exercise than at rest. This study examined the effect of neurofeedback-EEG training, which consisted in a reduction in the amplitude of the beta2 band (20-30 Hz) during exercise, on the results of behavioural tests that evaluated attention, reaction time and the shape of the work curve. The relationships between the EEG bands during exercise and the performance of the mind were also analysed. Material/ Methods: Electroencephalography (EEG) recordings were used to measure the bioelectrical brain activity in a group of 20 subjects performing exercise on a swimming ergometer (10 people) and an elliptical ergometer (10 people). The subjects were supposed to concentrate their attention on the visual stimuli presented on the screen installed c.a. 1 meter in front of their face. Before and after the EEG recording and after 20 neurofeedback-EEG training sessions, the subjects performed the Kraepelin work curve test (paper version). Results: After 20 neurofeedback training sessions, the amplitude in the inhibited beta 2 band was reduced. These changes in brain activity were accompanied by a reduction in reaction time, in the attention-reaction test, and in certain measures of the Kraepelin's work curve. Simultaneously, the relationships between measures of the work curve and the beta2 bands were observed. These relationships demonstrate a longer time of maintenance of quick working rate, high energy and persistence, maintaining attention and consistency in physical activity. Conclusions: Neurofeedback-EEG training in motion might be an effective method of improving work performance, connected with the engagement of attention while doing exercise. It can also ensure attention concentration for motion control and provide useful information about brain activity during physical activity and rehabilitation. Our data reveal that, under conditions of constant speed of movement, the brain shows stability and it even reduces its bioelectrical activity.
