Objective: Used skin electric resistance as an indicator to find the relationship between mental stability and practicing Qigong.
Methods: Twenty-five healthy male college students served as subjects. They were divided into three groups: long-term Qigong practicing group (Group A, 5 subjects, who had practiced Qigong over 2 years); short-term Qigong practicing group (Group B, 10 subjects, who had practiced Qigong for about 6-8 months); no practicing Qigong group (Group C, 10 subjects). All were volunteers.
To begin, 100db and 3000Hz noise were measured as the inhibitory stimulus, every 10 seconds until the value of the skin electric resistance no longer changed. This notes the maximum change two seconds after the stimulation and measures the electrode that was put on the two acupoints of the right hand: neiguan and shaochong. Then the continuous value of the skin electric resistance of the acupoints of the lower dantian and the right neiguan was measured for approximately 30 minutes (five minutes for silent standing, 20 minutes for standing exercise of Qigong, and 5 minutes for finishing the exercise).
1. The changes of value caused by the noise: The value of Group A did not change any more after 5 times, while Group B and C did so until 10 times. A one-way ANOVA was performed (F =118.7, (2, 22), P<0.01). The results show a significant difference between the Qigong group and the no-Qigong group.
2. The continuous value of the skin electric resistance: In Group A and B the value was improved (p<0.01) while in Group C the value did not change significantly (p>0.05). At the same time, significant difference was shown between Group A and B (p<0.01).
1. The subjects practicing Qigong have the ability to resist the negative simulation more readily than the groups without practicing Qigong, which suggests that mind stability can be improved by practicing Qigong.
2. Qigong can improve the excitation of parasympathetic nerve. At the same time, the level of the improvement has certain relationships with the duration of practicing Qigong.
