Research on the Influence of TCM Qigong Static Exercise on HRV of College Students

Abstract

To observe the influence of TCM Qigong static on HRV of college students, in this study 60 college students were randomly divided into an experimental group and a control group (30 students per group).Then the experimental group performed TCM Qigong exercises for 2 months, and the control group did not do any intervention. Finally the HRV data of the two groups of subjects under different conditions were recorded and analyzed. As a result, the RMSSD and PNN50 of the experimental group (in the state of TCM Qigong) were significantly higher than those in the third stage (sitting state) of the control group, (p<0.0l); in the experimental group, the RMSSD value was significantly higher in the Qigong state compared with the meditation state and the anxiety state (p<0.0l), and the PNN50 value also increased significantly (p<0.05); while the RMSSD and PNN50 of the control group changed during the three stages, the difference was not statistically significant (p>0.05). Compared with the first stage (meditation state) and the second stage (anxious state), there was no significant difference in HRV frequency domain indicators between the two groups (p>0.05). In the third stage, compared with the control group (mediation state), the experimental group (Qigong state) had significantly lower VLF, LF, and LF/HF values (p<0.05), and its HF value was significantly higher (p < 0.05). Therefore TCM Qigong exercises can regulate the activity of the heart’s autonomic nervous system (ANS) and make the activity of ANS more balanced.
