The 200 1 version clearly stipulates that athletes will be deducted 0.5 points if they don't dress correctly in the competition, and 0.2 points will be deducted in the 2005 version. It can be seen that as long as it is not the wrong dress, reducing the punishment of incorrect dress is to better reflect the characteristics of aerobics. However, the 2005 version of the rules also conforms to the characteristics of sports and competition norms. The new rules stipulate that the clothes of aerobics athletes must conform to the sports clothes described in competitive aerobics. Dramas, operas and circus costumes are prohibited. Athletes are also allowed to use flesh-colored bandages to protect their joints because of injuries. Male athletes must wear jumpsuits or vests, shorts and underwear. The whole dress must not have any openings, and male athletes must not wear long sleeves or a long-sleeved dress. Female athletes are allowed to wear long sleeves or a long-sleeved dress, but the sleeve length is limited to the wrist joint, otherwise it will be regarded as a dress mistake minus 2.0 points. It can be seen that although the penalty points for aerobics have decreased in the future, the requirements for competitions have not decreased but increased. Aerobics is also developing in a more standardized and athletic direction.
