A sport is an organized, competitive, entertaining, and skillful activity requiring commitment, strategy, and fair play, in which a winner can be defined by objective means. Generally speaking, a sport is a game based in physical athleticism. Activities such as board games and card games are sometimes classified as "mind sports," but strictly speaking "sport" by itself refers to some physical activity. Non-competitive activities may also qualify, for example though jogging or playing catch are usually classified as forms of recreation, they may also be informally called "sports" due to their similarity to competitive games.
Sports are governed by a set of rules or customs. Physical events such as scoring goals or crossing a line first often define the result of a sport. However, the degree of skill and performance in some sports such as diving, dressage and figure skating is judged according to well-defined criteria. This is in contrast with other judged activities such as beauty pageants and body building, where skill does not have to be shown and the criteria are not as well defined.
Records are kept and updated for most sports at the highest levels, while failures and accomplishments are widely announced in sport news. Sports are most often played just for fun or for the simple fact that people need exercise to stay in good physical condition. However, professional sport is a major source of entertainment.
While practices may vary, sports participants are expected to display good sportsmanship, and observe standards of conduct such as being respectful of opponents and officials, and congratulating the winner when losing
