A kick is a physical strike using the foot, leg, or knee (the latter is also known as a knee strike). This type of attack is used frequently by hooved animals as well as humans in the context of stand-up fighting. Kicks play a significant role in many forms of martial arts, such as Taekwondo, Sikaran, Karate, Pankration, Kung fu, Vovinam, Kickboxing, Muay Thai, Capoeira, Silat, and Kalarippayattu.
Karate (空手) (//; Japanese pronunciation: [kaɽate] ( )) is a martial art developed in the Ryukyu Islands in what is now Okinawa, Japan. It developed from the indigenous martial arts of Ryukyu Islands (called te (手), literally "hand"; tii in Okinawan) under the influence of Chinese martial arts, particularly to that of the Fujian White Crane. Karate is a striking art using punching, kicking, knee strikes, elbow strikes and open hand techniques such as knife-hands, spear-hands, and palm-heel strikes. In some styles, grappling, throws, joint locks, restraints, and vital point strikes are also taught. A karate practitioner is called a karateka (空手家).
Sport (or sports) is all forms of usually competitive physical activity which, through casual or organised participation, aim to use, maintain or improve physical ability and skills while providing entertainment to participants, and in some cases, spectators. Hundreds of sports exist, from those requiring only two participants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals.
Sport is generally recognised as activities which are based in physical athleticism or physical dexterity, with the largest major competitions such as the Olympic Games admitting only sports meeting this definition, and other organisations such as the Council of Europe using definitions precluding activities without a physical element from classification as sports. However, a number of competitive, but non-physical, activities claim recognition as mind sports. The International Olympic Committee (through ARISF) recognises both chess and bridge as bona fide sports, and SportAccord, the international sports federation association, recognises five non-physical sports, although limits the amount of mind games which can be admitted as sports.
Sports are usually governed by a set of rules or customs, which serve to ensure fair competition, and allow consistent adjudication of the winner. Winning can be determined by physical events such as scoring goals or crossing a line first, or by the determination of judges who are scoring elements of the sporting performance, including objective or subjective measures such as technical performance or artistic impression.
