In British English, sporting activities are commonly denoted by the mass noun "sport". In American English, "sports" is more used. In all English dialects, "sports" is the term used for more than one specific sport. For example, "football and swimming are my favourite sports", would sound natural to all English speakers, whereas "I enjoy sport" would sound less natural than "I enjoy sports" to North Americans.
The term "sport" is sometimes extended to encompass all competitive activities, regardless of the level of physical activity. Both games of skill and motor sport exhibit many of the characteristics of physical sports, such as skill, sportsmanship, and at the highest levels, even professional sponsorship associated with physical sports. Air sports, billiards, bridge, chess, motorcycle racing, and powerboating are all recognized as sports by the International Olympic Committee with their world governing bodies represented in the Association of the IOC Recognised International Sports Federations.
