The Commonwealth Games sports comprise all the sports officially recognised and approved by the Commonwealth Games Federation (CGF). There are a total of 16 core sports and a further 4 core para-sports that are competed at every games. In addition, the CGF allow organising committees to choose from various optional sports and disciplines to complete their games' program. At the 1930 British Empire Games, the precursor to the modern Games, there were six sports: athletics, aquatics (swimming and diving), boxing, lawn bowls, rowing, and wrestling. Sports, disciplines, events If a number of activities are controlled by the same international federation then the Commonwealth Games Federation recognises each activity as a discipline, which belongs to the respective sport. For example, shooting, which is organised by the International Shooting Sport Federation, is a sport at the Commonwealth Games that comprises four disciplines: clay target, full bore, pistol, and small bore. Furthermore, events for elite athletes with a disability (EAD) comprise a separate discipline within a sport from events for able-bodied athletes. This is the case both for sports where events for EAD and able-bodied athletes are organised by the different federations, as with athletics and World Athletics and the International Paralympic Committee, and for sports where there is a single federation, as with lawn bowls and the World Bowls. Sports and disciplines feature separate events for which athletes can receive medals. For example, boxing has a number of weight divisions, gymnastics and diving have a number of styles, while athletics has numerous events based upon a wide range of activities. Types The Commonwealth Games sports are divided into three main types: core sports, optional sports, and recognised sports. Sixteen core sports and four core para-sports must be included in the Games program, while the host nation may choose to include a number of optional sports and disciplines. Recognised sports are sports which have been approved by the CGF but are deemed to need further growth before their inclusion. The host nation may also apply for the inclusion of a maximum of four team sports to the CGF General Assembly, as the Melbourne organising committee did with basketball for the 2006 Games. The CGF recognises Commonwealth Games records for a number of sports. In 2002, the CGF introduced the David Dixon Award for the outstanding athlete of the Games.
