Effect Of Baduanjin Exercise On Implicit Regulation Of Negative Emotion

Baduanjin exercise is a kind of Chinese traditional physical and mental exercise.During the practice,in addition to paying attention to the form of action,it is also necessary to be accompanied by application of mind concentration,breathing and coordinating breathing with mind.Previous studies have shown that Baduanjin exercise can relieve the individual's severe negative emotions,but the psychological and neural mechanisms of Baduanjin exercise on negative emotions are still unclear.Inhibition control is the basis of emotional regulation.Studies have shown that Baduanjin exercise can promote individuals' inhibition control.Therefore,this study speculates that Baduanjin exercise can promote inhibition of negative emotions,that is,promoting the implicit regulation of negative emotion.To test this hypothesis,40 general college students were recruited,divided into experimental groups and control groups.Both groups included 20 individuals.The experimental group had 8 weeks of intervention by Baduanjin,and the control group did not perform any extra intervention to maintain the normal life and habits.Psychological,behavioral and ERP measurements were performed before and after the intervention.Measurements included the measurement of emotional Go/Nogo tasks,Psychological Stress Scale,Anxiety Scale,and Mood State Scale.A total of 34 subjects completed the entire experiment,including 17 in the experimental group(12 females),with an average age of 20.18�2.16 years and 17 in the control group(11females),with an average age of 21.24�2.25 years.There was no significant difference in the average age and sex ratio between the two groups.The results showed that: In terms of psychological measurement,there was no significant interaction between pre-test and post-test in perceived psychological stress,anxiety traits,total score of mood state scale,and subscale scores.The behavioral findings showed that the reaction accuracy rate showed that the measurement time(pre-test,post-test)� reaction type(Go,Nogo)� group(experimental group,control group)had significant interaction.Further simple effect analysis found that under the condition of post-test Nogo reaction type,the correct rate of the experimental group was significantly higher than that of the control group.There was no significant difference between the groups under other conditions.The N2 amplitude showed a similar pattern with the correct rate,that is,the reaction time � reaction type � group interaction was significant.Under the conditions of post-testNogo reaction type,the amplitude of N2 in the experimental group was significantly greater than that of the control group.More importantly,the N2 amplitude also showed measurement time(pretest,posttest)� response type(Go,Nogo)� emotional face type(neutral emotional face,negative emotional face)�group(experimental group,control Group)4 factor interactions.Under the conditions of post-test negative emotion expression Nogo reaction type,the amplitude of N2 in the experimental group was significantly greater than that of the control group,and the difference between the groups was not significant under other conditions.There was no significant interaction effect of N2 latency.The interaction of P3 mean amplitude measurement time � response type � emotional face type � group was significant.Under the conditions of post-test negative emotion face Nogo reaction type,the amplitude of P3 in the experimental group was significantly smaller than that of the control group.Under the condition of post-test neutral emotional face Go reaction,the amplitude of P3 in the experimental group was significantly lower than that of the control group.Response type � emotional face type � group interaction was significant.After simple effect analysis,it found that in the experimental group negative emotional face condition,the amplitude of Nogo reaction type was significantly greater than that of Go reaction type.The interaction of N170 latency response type � emotional face type � group was significant.Underthe conditions of post-testin the experimental group,negative emotional face conditions,the latencyof the Nogo reaction type was greater than that of the Go reaction type.Conclusion: After 8 weeks exercise of Baduanjin,the reaction of the experimental group to negative emotions was inhibited,suggesting that Baduanjin exercise promoted the adjustment of exercisers' implicit emotions.
