The Effect of the Controlled Respiration Period on Physiological Phenomena

The history of qigong can be traced back several thousand years in China. But now, it is spreading worldwide as a way for curing and preventing disease. There are many mechanisms in qigong which need to be clarified. One purpose of this research is to explain the mechanism of respiration which is important in the practice of qigong. We use the way normal people control their inhalation and exhalation time and measure their physiological phenomena, for example: SpO2, CO2, ECG, PPG, RSP, blood flow etc. From the results we find that the ability to adjust their own bodies differ between the people, even when they are asked to breath with the same posture and in the same way. This means for the basic exercises in qigong, we must consider how to practice each one properly, because people have different body features.
