Abstract: In recent years, there has been significant uptake of meditation and related relaxation techniques, as a means of alleviating stress and fostering an attentive mind. Several electroencephalogram (EEG) studies have reported changes in spectral band frequencies during Qigong meditation indicating a relaxed state. Much less is reported about effects on brain activation patterns induced by Qigong techniques involving bodily movement. In this study we tested whether (1) physical Qigong training alters EEG alpha activation after a six-week intervention, (2) differences in brain activation patterns occur in novice compared to advanced practitioners, and (3) high frequency training leads to increased alpha activation in novice practitioners. Two beginner groups (two and five training sessions per week) and one advanced group (two training sessions per week) underwent a six-week Qigong intervention. Spontaneous resting EEG was recorded before and immediately after each 15-minute exercise in the first and sixth week. Increased alpha power was obtained in frontal and central regions in advanced practitioners after Qigong exercise in pre- and post-test. A high frequency training schedule did not increase alpha activity in beginners. Results indicate that alterations of brain activation patterns induced by acute Qigong exercise are promoted by a long-term training process.
