Researchers in China studied the EEG pattern of a Qigong practitioner with 50 years of experiences in Qigong practice (Qin et al., 2009). They found that after 50 years of practice, the resting EEG of the practitioner had frontally dominant alpha-1, compared with the occipitally dominant alpha-2 observed in the year of 1962.
The researchers observed that during the Qigong practice, alph-1 increased very fast and were much more significant than it was 50 years ago (Qin et al., 2009). These findings indicate that long-term practice of Qigong may influence the EEG pattern of the brain, as well as the neurophysiology activities.
Such changes may have biomedical effects and clinical impacts that have been observed in long-term Qigong practitioners. Further studies are necessary to elucidate the mechanisms of these changes and their possible beneficial effects on health.
