title: Effects of Qi-training (Qigong) on forearm blood gas concentrations.
abstract: Using an ABA' design, the authors investigated the effects of Qi-training on blood gas concentrations with a 20 min control rest period (A), 1 h of Qi-training (B), and a 20-min rest period (A'). The blood partial pressures of oxygen (PO2) and carbon dioxide (PCO2), and oxygen content, oxygen saturation, and pH were significantly altered. The mean PO2 value increased significantly during Qi-training by 14 mmHg (about 24%, p < .01) compared with control A. During Qi-training, the mean decrease in PCO2 was 3 mmHg (about 10%). These results suggest that the practical application of Qi-training may exert a positive regulatory function on physiological status.
