| 【Objective】To analyze the changes of heart rate variability(HRV)in different visual and auditory stimuli in the process of sports dance viewing,explores the influence of sports dance on the viewer’s physical and mental health,and provides experimental basis for the application of ornamental aesthetic education in sports dance teaching.【Methods】Experimentation.A total of 48 undergraduates(age 19.79 ± 0.71)were selected from Guangzhou Institute of physical education as the research subjects,including 24 males and 24 females.The 48 subjects were divided into three groups(experiment 1 group,experiment 2 group and experiment 3 group),each group included 8 males and 8 females,which enjoy the performance videos of Cha Cha,Rumba and Jive in the order of CRJ,RJC and JCR.The experiment is tested with the physiological coherence and autonomic nerve balance training system(SPCS),and the experimenter collected relevant data before,during and after the experiment,used the system to analyze data by paired t-test and independent sample t-test were used by SPSS19.0 software.【Results】(1)Comparison of HRV changes in different stages.Compared with the experiment before,the mean values of TP,HF,coordination,stability and evaluation indexes in Cha Cha decreased significantly(P<0.05),while HR increased significantly(P<0.01),the mean values of TP,LF and HF decreased significantly(P<0.05)in Rumba and Jive.Compared with the experiment,the mean values of TP and LF in Cha Cha,Rumba and Jive increased significantly(P<0.05).Compared with the experiment before,the HF mean value of Rumba and evaluation index decreased significantly after the experiment(P<0.05).(2)Comparison of HRV changes among different dance species.In the process of Cha Cha and Rumba viewing,compared with the experiment before,the mean value of HR increased significantly,while that of HF decreased significantly(P<0.05),the LF/HF mean value of Cha Cha decreased significantly,while increased significantly in Rumba(P<0.05);compared with the experiment,the mean value ofstability index increased significantly after experiment(P<0.05),the mean value of coordination and evaluation index increased significantly in Cha Cha,while decreased significantly in Rumba(P<0.05).In the process of viewing Rumba and Jive,compared with the experiment before,the LF/HF mean value of Rumba increased significantly,while decreased significantly in Jive(P<0.05).In the process of viewing Cha Cha and Jive,the HR mean value increased significantly before and after the experiment(P<0.01).(3)Comparison of HRV changes between different genders.Compared with the experiment before,the HR mean value of Cha Cha in the experiment increased significantly(P<0.05),and that of girls was higher than that of boys.Compared with the experiment before,the HR mean value of boys decreased significantly,while increased significantly in girls after the experiment(P<0.01).Compared with the experiment,the LF/HF mean value of Jive increased significantly in boys,while decreased significantly in girls(P<0.05).(4)Comparison of HRV changes in viewers with different personalities.In the aspect of introversion and extroversion,compared with the experiment,the mean value of evaluation index in Cha Cha increased significantly in the high group,while decreased significantly in the low group after the experiment(P<0.05);compared with the experiment before,the TP mean value of Cha Cha decreased significantly in the high group,while increased significantly in the low group after the experiment(P<0.05);the mean value of coordination and evaluation index in Rumba decreased significantly in the high and low group(P<0.05),the evaluation index increased significantly in the high group,while decreased significantly in the low group(P<0.01);the LF/HF mean value of Jive increased significantly in the low group,while decreased significantly in the high group(P<0.05).In terms of emotional stability,compared with the experiment,the HF mean value of Rumba increased in high group,while decreased in low group after the experiment(P<0.05).【Conclusion】The heart rate variability of different dance species,different gender and different personality sports dance spectators all had some differences,and showed regular changes in different stages of appreciation. |
