In order to probe some characteristic physiological changes on the human body under the qigong state, and to probe the length of the time the practiser of qigong must need according to this data, the CBF, EBF etc. were checked on 25 patients who practised qigong exercises to compare with 10 patients in the control group. During this experiment, we got initial significant results.
Out of the 25 patients, 10 practise Zhoutiangong, 5 internal qigong, 5 Xuminggong, 5 Fenxineryonggong. They did the qigong exercises four times daily, one hour for each. At the same time, they must do Daoyinxing qigong to prevent deviation, each time for half an hour.
Before the qigong exercise, each patient was examined of CBF, stroke volume (SV), upper limb blood flow (ULBF), lower limb blood flow (LLBF) and breathing frequency (BF). Then they did the exercise under the guide of a qigong master. Two months later, the percentage of each item under the qigong state and normal physiological state was calculated. The control group was examined and calculated in the same way.
Through observation there was no marked difference in CBF, ULBF, LLBF and BF in 5 minutes or 10 minutes after the qigong state either in the qigong group or in the control group.
Two months after the qigong exercise, the BF, CBF in the qigong group decreased by 26 percent, 3.9 percent respectively. The BF and CBF in the control group decreased by 3.9, 1.6 percent respectively (P<0.01). There was remarked difference on statistics. This shows that the slowed CBF and decreased BF are two important items in the qigong state.
Although the BF and CBF have dropped remarkably 5 minutes under the qigong state, the BF and CBF have increased 3.2 percent and 0.2 percent respectively 10 minutes earlier. This indicates that these people are in the primary stage, conforming to the ancient saying 'the primary stage needs 100 days in Xiaozhoutian'. In other words, the qigong practisers who are at the beginning stage at least do the qigong exercise for two months.
Clinically, 10 out of the qigong group suffered from different chronic disease. After two months of practising Zhoutiangong, they all recovered to some extent. 2 out of 10 were cured, 7 were on the mend. Only one patient failed. This tells us that the Zhoutiangong is effective to some chronic disease.
