Effects Of Dance Movement Therapy On Sports Mental Fatigue Of Pregame Sanda Athletes With Weight Loss

Athletes belong to high-pressure groups,and are groups that are prone to sports-induced mental fatigue due to physiological and psychological depletion caused by internal and external stress,especially for pre-match weight-reducing athletes.The purpose of this study was to investigate the intervention effect of dance therapy on the mental fatigue of athletes who lost weight before the Sanda competition.Taking the 23 male athletes of the professional Sanda competition in Fujian Province Sports Vocational and Technical College,using the literature method,questionnaire method,measurement method,mathematical statistics method and interview method,by measuring the sports mental fatigue questionnaire(ABQ),heart rate variability(HRV)and Stroop task indicators and interview evaluations were used to assess the impact of dance intervention on mental fatigue.The results are as follows: 1.ABQ questionnaire: The scores of the three dimensions of the experimental group's decline in sense of accomplishment,emotional/physical exhaustion and negative sports evaluation were lower than before.The number of severe mental fatigue decreased from 11 before the intervention to 6 and the percentage of severe mental fatigue decreased from 91.7% before intervention to 50%.The five subjects with severe mental fatigue before intervention were converted to mild mental fatigue after intervention.In the control group,the scores of the three dimensions of decline in sense of accomplishment,emotional/physical exhaustion,and negative exercise evaluation increased.The number of severe mental fatigue increased from 9 to 11 before intervention,and the percentage of severe mental fatigue increased from 81.8% before intervention to100%.Two patients with mild mental fatigue before the intervention developed severe psychological fatigue without intervention.2.Heart rate variability: HF,TP,SDNN,and RMSSD in the experimental group HRV index were significantly increased,and LF/HF decreased significantly.The LF/HF in the HRV index of the control group was significantly increased.3.Stroop task: The reaction time of the experimental group was significantly shortened,and the correct rate was significantly improved.There was no significant change in the reaction time and the correct rate of the control group.4.Interview evaluation of the participants: The influence of the surrounding dance exerciseson the participants was relaxation,calmness,release,self-confidence,unity support,concentration,and sleep improvement.In summary,the surrounding dance intervention can alleviate sports mental fatigue to a certain extent.Improve the activity of the autonomic nervous system and central nervous function.Moreover,after the intervention,the athletes felt that the performance of each dimension of psychological fatigue improved earlier,and they tend to relax,calm,autonomous and support each other.
