Although there have been reports on changes in breathing and brain blood volume during Qigong, the relationship between them was not clear. In this study, the relationship between the total hemoglobin concentration of the cerebral cortex and breathing of six Qigong trainers during Qigong was analyzed. As a result, there was no correlation between the brain blood volume and the amount of breath per minute. It is suggested that the brain blood volume of Qigong trainers changed by consciousness activities of the Qi-emission task, and not by breathing.
