Olympic Games
The Olympic Games programme consists of 35 sports, 30 disciplines and 408 events. For example, wrestling is a Summer Olympic sport, comprising two disciplines: Greco-Roman and Freestyle. It is further broken down into fourteen events for men and four events for women, each representing a different weight class. The Summer Olympics programme includes 26 sports, while the Winter Olympics programme features 15 sports. Athletics, swimming, fencing, and artistic gymnastics are the only summer sports that have never been absent from the Olympic programme. Cross-country skiing, figure skating, ice hockey, Nordic combined, ski jumping, and speed skating have been featured at every Winter Olympics programme since its inception in 1924. Current Olympic sports, like badminton, basketball, and volleyball, first appeared on the programme as demonstration sports, and were later promoted to full Olympic sports. Some sports that were featured in earlier Games were later dropped from the programme.
International University Sports Federation
As of 2019 the list of compulsory sports will be expanded with archery included into the sports programme, as well as badminton in 2021. Optional sports vary from one Summer Universiade to another. Depending on their own interests, Organising Committees may choose from the list of the World University Championships (WUC) up to 3 optional sports to be included in their specific sports programme. For the most recent Universiades in Shenzhen (CHN), Kazan (RUS) and Gwangju (KOR) the total number of sports has reached a peak with 24, 27 and 21 sports featured respectively.In Taipei were 21 again. In order to reduce the scale of the Universiade and more easily find future candidate cities, FISU prefers that the number of optional sports return to the number of 3.
