Sports dance is a new sports event, which is a combination of sports and dance. It has the duality of sports and art, and is full of the flavor of the times and the nature of sports competition. It was listed as an Olympic performance event and a competition event at the fifth China Sports Science Conference in 2000. The establishment of ancient music and dance in China is also to change the situation that "the people are depressed and stagnant, and their bones and muscles can't reach". American athlete Guric once said: "Dancing can eliminate excess fat and replace it with strong muscle tissue, so that softened, late and inactive muscles are full of vitality and elasticity again." In Germany, someone made a comparison between an amateur sports dancer and a 800-meter runner, and found that the heart rate of the sports dancer was no different from that of the 800-meter runner after skipping the 15 minute quickstep.

2, the value of a healthy attitude

Active participation in sports can not only strengthen the body, but also regulate and promote mental health, which has become the symbol of modern sports concept. This dual effect of sports activities is also being confirmed by more and more modern sports scientific research institutions. The mental health level of holders who actively participate in sports dance activities is obviously higher than that of ordinary people, which shows that sports dance has a very obvious promoting effect on mental health. In recent years, the cardiotonic effect of aerobic exercise has been confirmed by more and more scientific research. For example, studies by Petruzzlo (199 1) and Lafontaine (1992) show that aerobic exercise can not only reduce anxiety, but also reduce depression. Aerobic exercise has therapeutic effect on long-term mild to moderate anxiety and depression. Anaerobic exercise can only regulate and treat depression, but can not effectively reduce anxiety. Therefore, if you want to improve the overall emotional state, it is best to use aerobic exercise, and the heart-building effect of aerobic exercise should be more significant. From the research results of sports dance physiology and biochemistry, we can know that sports dance is an aerobic exercise with moderate exercise intensity. According to the research of Lafontaine and others, this aerobic exercise has a significant regulatory effect on emotional disorders such as anxiety and depression.

From the social value of sports, sports dance is one of the best forms for people to exchange ideas, express their feelings, eliminate barriers and communicate with each other. Accompanied by beautiful dancing and brisk music, people's self-enclosed consciousness will be completely liberated here, and the harmonious, harmonious and elegant atmosphere on the dance floor can also enhance people's communication consciousness. It can be seen that sports dance activities enhance the friendship between partners and dancers, enrich social life and improve the interpersonal skills of participants. According to the research results of Situ Bingkun and others, the scores of sports dance activities on "interpersonal relationship" and "hostility" are significantly lower than the national norm level, which shows that sports dance activities have a significant positive role in promoting these two mental health factors. It can be considered that sports dance is very beneficial to physical and mental health, especially mental health.

3. Ornamental value

Sports dance has not only become a good form for people to establish friendship, cultivate sentiment, exercise and improve skills, but also has unique artistic performance value, which gives dancers and viewers beautiful enjoyment, makes people happy physically and mentally, and then improves people's artistic accomplishment and aesthetic taste.

The predecessor of modern dance is European ballroom dance, which originated from the court dance of Louis Dynasty in France. Social dancing is a necessary accomplishment in Europe and a healthy entertainment for all ages. In the early stage of the evolution from court dance to social dance, men have a set of etiquette moves to invite women, and women also have a set of etiquette moves to accept. This kind of etiquette was necessary when inviting high-class partners at that time. With the development and progress of the times, mutual respect between men and women, especially respect for women, has become the basic requirement of modern social civilization. In modern dance, the ritualized aesthetic tendency still retains the solemn clothing and dignified posture of men, even in the change of light jumping steps, it is elegant. Because the aesthetic orientation of etiquette determines the importance of elegance, there are higher requirements for dancers' appearance and elegance. The first condition to form elegant manners is intuition, which shows health, education, courtesy and self-esteem, and gives people a feeling of happiness, excitement and youthful vitality. These are not only the requirements for dance style, but also the respect for the audience. For example, men are holding women's hands into the venue, guiding their partners to spin quickly and then paying tribute to the audience, while women are offering a classical knee-jerk ceremony to the surrounding audience; After the dance, the male and female dancers not only bowed to the audience, but also the men pointed to the ladies and smiled, which gave people beautiful enjoyment and aftertaste. The famous British philosopher Siqi. Bacon said; "The beauty of beauty, elegance and graceful movements is the essence of beauty". In a performance or competition, players should conform to the purpose of elegance and elegance in both actions and manners.

The regulations on athletes' clothing in sports dance competitions strengthen their appreciation. Modern dance and Latin dance in sports dance have their own special costumes. Because dance styles are different, different styles of clothes are needed to set off. Modern dance, for example, mainly embodies the European style. Men dress in formal etiquette activities, wearing deep and elegant tuxedos, tying a white-collar knot around their necks and shoes at the bottom of the wheels, keeping their hair clean and tidy, showing solemn and noble bearing and beautiful body lines; Women wear backless long evening dresses, and the specific styles and colors also change with the trend of the times. For example, women's dresses before the 1990s were made of silk, and after the 1990s, they were made of yarn, silk and ostrich hair, which made the skirts more elegant and colorful. In Blackpool, England in 2000, silk yarn fabric appeared again. The multi-layer knee-length skirt with ostrich hair removed dances like the wind in the clouds, with fine workmanship and high price. Ladies put on this dress, and immediately they look dazzling. Their bodies are so elegant and charming. They rotate like blooming lotus flowers, giving people a three-dimensional and colorful image and pushing the beauty of clothing to the highest level. Therefore, in the process of showing the beauty of modern dance, it is extremely important for clothing to set off and beautify. Latin dance costumes often show lively, free and unrestrained Latin American sentiment and life breath. Through flexible waist and hip movements, dance deliberately pursues the curvaceous beauty of human movement, showing the graceful dexterity of ladies. In Latin dance costumes, men wear tights, while women can fully show the curvy beauty of their bodies, bareback and bare legs, thus showing the beautiful lines of back, waist, hips and buttocks, and improving the dance style. In recent years, Latin dance costumes have also absorbed others. The distinctive national style of clothing in sports dance doubles the elegance of male and female players. As a manifestation of culture, clothing reflects the cultural characteristics of a nation to some extent.
