the cortical and extra-cortical bioelectrical processes determining the neurobiofeedback success and efficiency of sportsmen

The changes of the functional condition of the 35 highly qualified sportsmen, neurodynamic and its changes of the frequency characteristic of the heart rate in the background recording during open and closed eyes before and after 15-days neurobiofeedback course is analyzed. It is discovered, that the functional left hemisphere asymmetry was typical for sportsmen having the quiet wakefulness condition according the power of all main rhythms of the EEG. It is defined, that the predictor of the training efficiency is the theta-rhythm power in the recording during open eyes. The VLF-wave and the HF-wave middle power of the heart rate frequency and probably the hormonal cycle of women body have the material effect to training success.
