The term "sport" refers to any kind of physical competition or game that is designed to enhance, maintain, or develop athletic ability and performance as well as provide enjoyment to the participants and, at times entertaining for spectators. Sports can, through either casual or organised participation, improve one's physical health. Hundreds of sports exist with a variety of different types, from sports that involve single contestants, through to those that involve hundreds of simultaneous participants, either in teams or as individuals. In certain sports such as racing, a lot of contestants participate simultaneously or in a series, with one winner; in others, the contest (a match) is between two teams, each attempting to exceed the other. Certain sports allow the possibility of a "tie" or "draw" that has no winner. Other sports provide tie-breaking techniques to ensure one winner and one loser. A number of contests may be held in a tournament that result in a winner. Many leagues of sports create an annual champion with the help of games in a regular sports season. They are then followed in a few instances by playoffs.
Sport is generally recognised as system of activities based in physical dexterity or athleticism, with major competitions such as the Olympic Games admitting only sports that are in line with this definition. Other organisations, such as the Council of Europe, preclude any activities with no physical element from classification as sports. There are however a few competitive, but non-physical, activities are recognized for mind games. The International Olympic Committee (through ARISF) recognizes both chess and bridge as legitimate sport, as well as Sport Accord, an international sports federation association, recognises five non-physical sports that include bridge, chess Draughts (checkers) Go, draughts, and xiangqi. It also limits the number of mind games that can be admitted as sports.
The rules of sport are usually rules or conventions, which provide fair competition, and allow to ensure that the winner is a fair adjudication. Winners can be determined using physical events such as scoring points or crossing a line first. It could also be determined by judges who have the task of scoring the athletic performance, including scores that are objective or subjective, like technical performance or artistic impression.
he performance records of athletes are frequently maintained, and in the case of popular sports, these records can be announced widely or included in sport news. Sport is also a key source of entertainment and entertainment for those not participating and spectator sports draw huge crowds to sporting venues, and reaching wider audiences via broadcasting.

Artifacts and structures suggest sport existed in China beginning as early as 2000 BC. Gymnastics appears to have been commonplace in China's earlier times. Monuments to the Pharaohs show that a variety of sports, including fishing and swimming were well-developed , and were regulated millennia earlier in the era of ancient Egypt.

Sports science is an incredibly popular academic disciplinethat is applicable to areas like athlete performance, for instance as using video analysis to refine techniques, or to the design of equipment that are more efficient, such as running shoes or competitive swimwear. Sports engineering became an academic discipline in 1998, with an increasing focus not just on the design of materials but also on the use of technology in sports which ranges from analytics to big information to technology that wears. To regulate the effect technological advancements on fair playing, governing institutions often have specific rules that are set to limit the impact of technological advantages between athletes. In 2010, for instance, full-body, non-textile swimsuits were removed by FINA since they were enhancing swimmers' performance.

There isn't enough evidence which proves the effectiveness of the interventions designed to increase participation in the community sports , like mass media campaignsor educational sessions, or changes in policy. Also, there are no high-quality research studies to examine the effects of these interventions in promoting healthy behaviors in the community.

Sport can be conducted either on an amateur, professional or semi-professional basis, based on whether participants are incentivised for their participation (usually through the payment of wages or salaries). Sport participation for amateurs at lower levels is usually called "grassroots sport".
The growing popularity of sport for spectators as a leisure activity for non-participants has made sport an important business in its own right. this has incentivised a high earning professional sports culture in which the best athletes receive a salary far higher than the average wage and could reach million dollars.
Some sports, or the individual events within a sport are permitted only amateur competition. In the beginning, Olympic Games started with a basis of amateur competition, with the athletes who competed professionally thought to be having disadvantages over those who played just for fun.
