The reason why curling competition should wipe ice is because friction can increase the temperature of the ice surface and make the ice surface quickly melt into a thin layer of water. With a thin layer of water, the direct contact area between curling and ice is reduced, that is to say, the friction between curling and ice can be reduced and it can slide further. Increasing the speed can also control the trajectory of curling. Those balls that bypass the obstacle course must pass through it to reach. Figure skating clothing also has a history of gradual improvement. At the beginning of this century, figure skating was still an outdoor ice event in winter. In order to resist the cold weather, clothes are thick. Female athletes wear tight buttons, long skirts and feet. Male players wear tall hats, long tuxedos and long suit pants. In the 1920s, sonja henie, the world champion of 10 and the winner of three-time Winter Olympics, made a bold reform in women's wear, raising the skirt to the knee. This amazing pioneering work has created favorable conditions for the progress of women's single skating technology.

At the same time, men's wear has also improved, and waist-length short suit tops and ballet tights are much more convenient to slide. After the 1940s, women's skirts became shorter and shorter, and a short skirt with a top and skirt appeared. In order to meet the needs of performance, the clothes are decorated with raw edges, sequins, beads and so on. After World War II, female skaters began to wear white or flesh-colored skates. Work hard on fashion design and production. Due to the development of modern industry, spandex and other fabrics have appeared, which are more suitable for the training and competition of figure skating. The selection, coordination and design of colors are conducive to the expression of musical characteristics and dance styles, which greatly improves the artistic performance effect. Clothing has become an important part of the players' complete set of movements and artistic performances.
