Changes in alpha wave and state anxiety during ChunDoSunBup Qi-training in trainees with open eyes

Abstract

We investigated the effects of ChunDoSurBup(CDSB) Qi-training, one of the Korean popular Qi-training systems, on EEG patterns, activation coefficients and state anxiety in 13 trainees with open eyes. CDSB Qi-training procedure consists of 3 stages: sound exercise, reciting Chunmoon, which is similar to a mantra; haeng-gong, a kind of body motion; and meditation. Compared to the control state (resting state before Qi-training), subjects reported less state anxiety, their activation coefficients decreased significantly during sound exercise and meditation in the occipital regions. Mean relative power and changes of mean absolute power of alpha wave increased significantly during sound exercise and meditation in the occipital regions. These results suggest that sound exercise and meditation in ChunDoSunBup Qi-training may reduce activation of the visual cortex and influence the thalamus and other functions of the brain. These could reduce anxiety levels and modulate the psychological, neurological, and physiological functions in man.
