Wireless EEG system for Sport Science: quantitative analysis of movement

The study considered data from EEG rhythms in the eyes-closed at rest and the eyes-open condition during dynamic movements in real-time soccer training. EEG recorded from the orbitofrontal cortex using the NeuroSky single-channel wireless mobile system with pair dry non-contact sensors. The participants included professional male soccer players. Results from this study showed a reduction in the power spectrum of EEG rhythms during soccer training compared to the rest condition and demonstrated statistically significant differences $(\pmb{p} < \mathbf{0.03})$ between the rest and during dynamic movement conditions obtained as the summary value of bands in EEG power spectral estimates (1–50 Hz). The decrease the power spectrum in frontal areas associate with “neural efficiency” among team sports athletes and relationship to cognitive function as well. In addition, the findings are interpreted to suggest that delta rhythm is a plausible neurobiological index of physical fatigue during sport training among soccer players. These findings encourage the application of wireless portable EEG systems for studies of brain functions among sportspersons.
