The effects of four various Qigong breathing pattern on variability of heart rate have been observed by R-R interval spectral analysis in 26 healthy volunteers. The differences in the shape of peaks in spectra were found to be correlated with the Qigong breathing pattern. The amplitude of peak in high-frequency area increased with a reduction of the low-frequency 2/high-frequency (LF2/HF) ratio during the Qigong breathing pattern A, B, and C, indicating the vagal activity increased during above-mentioned three Qigong breathing pattern. However, the amplitude of peak decreased and LF2/HF ratio increased during the Qigong breathing pattern D, it reflected the increase of sympathetic activities. Thus, the results suggested that the Qigong could indirectly regulate the function of viscera after controlling the direct breathing pattern.
