Application Of High-intensity Interval Training In Improving Aerobic Capacity Of Chinese Classical Dancers

High intensity interval training as a popular sports training mode at home and abroad,with time-saving,efficient advantages.In this study,high intensity interval training is applied to dance.According to the particularity of dance training,combined with the actual situation of dancers and based on the Gihon content of dance,an appropriate high intensity interval dance training method is designed,aiming to provide a scientific and effective method reference for the training of dancers’aerobic capacity.Research Methods:The subjects of this study were 20 female students majoring in Chinese classical dance,who were divided into2 groups:the experimental group and the control group,which adopted two kinds of exercises:high-intensity interval dance training and traditional basic skills training.The intervention content of the experimental group was to select and integrate the action combinations on the basis of Chinese classical dance Gihon combinations,so as to adapt to the target exercise intensity.The action combinations of turning and jumping training were mainly adopted,and the exercise intensity was 80-95%HR_max.The intervention content of the control group was the Chinese classical dance Gihon training,and the exercise intensity was 70～85%HR_max.The ratio of exercise time to interval time was 1:1.Both groups were trained 3 times a week for 8 weeks.Before and after intervention,a20-meter return run was used to test the maximum oxygen uptake.Paired sample t-test and independent sample t-test were performed on the test results.During the intervention,heart rate meter was used to monitor the resting heart rate and recovery heart rate during exercise,and repeated measurement variance test was performed on the monitoring results.Results:There was no statistical difference in each index between the two groups before training intervention.（1）The maximum oxygen uptake in the experimental group decreased significantly after intervention（Table values:p=0.001<0.05;Formula value:p=0.001<0.05）,while there was no statistical difference in the control group before and after intervention（Table values:p=0.603>0.05;Formula value:p=0.404>0.05）.（2）In terms of body shape,there was no statistical difference in body weight and body fat percentage between the two groups before and after intervention,but there was no statistical difference between the two groups（The experimental group:p=0.000<0.05,The control group:p=0.008<0.05）.（3）There was no significant difference in subjective fatigue（RPE）between the experimental group and the control group after intervention（p=0.023<0.05）,but there was no significant difference between the two groups.（4）During the 8-week intervention,the resting heart rate in the experimental group decreased significantly,as did the control group.The decrease rate in the experimental group was greater than that in the control group,and there were significant differences between the two groups at different time points（p=0.022<0.05）.（5）In the experimental group,the heart rate recovery rate at 1,2 and 3 minutes after exercise significantly increased,while in the control group,the rate fluctuated,and there were significant differences between the two groups.Conclusion:High intensity interval dance training can significantly improve the maximum oxygen intake of dancers,reduce the resting heart rate,speed up the recovery of heart rate significantly,and delay the appearance of exercise fatigue.It can effectively improve the aerobic capacity of dancers,and its effect is better than that of traditional dance basic training.
