To become an Olympic event, a sport must first be recognized by the IOC. To obtain this recognition, the sport must have an international association, and there must be at least. 75 national teams in the men's division and 50 national teams in the women's division. Furthermore, there must be a national association in each of these countries, and regular competitions must be held every year.
但要成為奧運項目，首先要被奧委會承認，條件是成立國際性組織，男子比賽項目要有七十五個會員國，女子比賽要有五十個會員國，除這些國家都已成立協會，每年也要固定舉辦比賽。
