| 中文摘要: |
| 应用R-R间期频谱分析方法观察了4种不同气功调息方式对心率变异的影响。对26名受试者的实验结果表明,不同调息方式有着不同的调息谱峰,当气功调息处于A、B和C形式时,其高频峰幅增大,低频(2)/高频比值(LF2/HF)下降,意味着迷走神经活动增强;而当气功处于调息形式D时,则其峰幅下降,LF2/HF增大,反映交感神经活动增强。提示气功能够通过对呼吸形式的直接控制来达到对内脏功能的间接调节目的。 |

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