Health Qigong is a common technique of Traditional Chinese Medicine applied to strengthen mental and physical health. Several studies report increases in EEG theta and alpha activity after meditative Qigong techniques indicating a relaxed state of mind. To date, little is known on the effects of dynamic Health Qigong techniques that comprise bodily movements on brain activity. In the current study, we compared effects of two dynamic Health Qigong techniques on EEG brain activity. Subjects performed the techniques (five animals play) and (six healing sounds) in a within-subjects design. Eyes-open and eyes-closed resting EEG was recorded before and immediately after each 15-min practice block. Additionally, the Profile of Mood States (POMS) questionnaire was administered at pretest, and after each 15-min practice block. Results show a decrease in alpha activity after 15 min, followed by an increase after 30 min in the Health Qigong technique . Theta activity was decreased after 15 min, followed by an increase after 30 min in the technique . Results of the POMS indicated an increased vigor-activity level with decreased fatigue and tension-anxiety levels in both techniques after 30 min of practice. Our results demonstrate different temporal dynamics in EEG theta and alpha activity for the Health Qigong techniques and . We hypothesize that the found brain activation patterns result from different attentional focusing styles and breathing techniques performed during the investigated Health Qigong techniques.
健身气功是中医用于增强身心健康的一种常见方法。多项研究报告称,冥想气功练习后脑电图的θ波和α波活动增加,表明心境处于放松状态。迄今为止,对于包含身体动作的动态健身气功技术对大脑活动的影响知之甚少。在当前研究中,我们比较了两种动态健身气功技术对脑电图大脑活动的影响。受试者在自身对照设计中进行了两种功法(五禽戏)和(六字诀)的练习。在每个15分钟的练习时段前后,分别记录睁眼和闭眼静息脑电图。此外,在预测试时以及每个15分钟练习时段后,发放情绪状态量表(POMS)问卷。结果显示,在健身气功功法练习15分钟后α波活动减少,30分钟后增加。在功法练习中,θ波活动在15分钟后减少,30分钟后增加。POMS的结果表明,练习30分钟后,两种功法的活力活动水平均有所提高,疲劳和紧张焦虑水平均有所降低。我们的结果证明了健身气功功法和在脑电图θ波和α波活动中存在不同的时间动态变化。我们推测,所发现的大脑激活模式是由所研究的健身气功技术中不同的注意力聚焦方式和呼吸技术导致的。
