Ma used a set of moves that shocked the world in the uneven bars final of the Los Angeles Olympic Games. After somersault 360 degrees, because the difficulty coefficient of this movement is too high, he later named it after the horse directly, which is called "under the horse". But this action was restricted soon after it came out, and the method of restricting this action was even more surprising.
In fact, the International Gymnastics Center changed the distance between uneven bars because of the horse's action, because they think that this action is not only dangerous, but also has deep hidden dangers for athletes, especially female athletes, because they often hit the lower abdomen during training, which is very unfavorable to women. With the revision of the rules, athletes can make more ornamental and difficult loops. In addition, Ma announced his retirement after the Olympic Games, so Ma's next move was gradually lost.
To sum up, we can know that the main reason why the gymnastics movement "dismount" is banned is that the women in this action team have been greatly hurt in the competition, and it will eventually be banned. Although it is a pity to do gymnastics like this, just like God, no matter what exercise you do, your own safety must come first, so the ban is also the protection for other gymnasts.
