INFLUENCE OF MUSIC RHYTHM ON DANCE EFFECTS AND EXERCISE INTENSITY IN QI DANCE ARRANGEMENT: AN EXPERIMENTAL STUDY

Abstract

As a form of exercise that integrates sports, music, dance and national culture, Qi dance is widely popular for its unique fitness effect and viewing value. However, there is still a lack of in-depth research on the specific mechanism of music rhythm in Qi dance. Therefore, this study systematically analyzes the effects of different rhythm music on Qi dance performance and exercise intensity through experimental design. This study selected 32 Qi dance enthusiasts and divided them into two groups. Half of the subjects performed Qi dance exercises under fast-tempo music (above 120 BPM), and the other half performed the same Qi dance exercises under slow-tempo music (60-80 BPM). The pre-test data were the data of the subjects performing Qi dance exercises under medium music rhythm (80-120 BPM). The exercise intensity was indicated by measuring the data of red blood cells, hemoglobin, hematocrit, and mean corpuscular volume, the dance performance effect was evaluated by expert scoring, and the physical health status was indicated by GDS (Geriatric Depression Scale), MMSE (Mini-Mental State Examination), and SQS (Sleep Quality Scale). The independent sample t test was used to compare the differences in exercise intensity, dance effect, and physical health status between fast and medium rhythms, and between medium and slow rhythms. The experimental results showed that, except for the mean corpuscular volume data, the red blood cells, hemoglobin, and hematocrit of the fast music rhythm were greater than those of the medium music rhythm data (P<0.001), and the red blood cells, hemoglobin, and hematocrit of the slow music rhythm were less than those of the medium music rhythm data (P<0.05). The fast music rhythm increased the exercise intensity. The expert scoring results of the dance effect showed that the dance expressiveness, strength, and total score of the fast music rhythm were higher than those of the medium music rhythm data (P<0.05), while the dance strength and total score of the slow music rhythm were lower than those of the medium music rhythm data (P<0.05). The SQS data of the fast music rhythm was higher than that of the medium music rhythm (P<0.05), while the SQS data of the slow music rhythm was lower than that of the medium music rhythm (P<0.05). The intervention of slow music rhythm will improve sleep quality. Music rhythm plays an important role in Qi Dance arrangement. Fast-paced music can increase exercise intensity and enhance the fitness effect of dance.
