Boxing, also called pugilism, is a combat sport in which two men or women fight each other using punching strikes for competition. Boxing is typically supervised by a referee engaged in during a series of one- to three-minute intervals called rounds, and boxers are generally of similar weight. There are four ways to win; if the opponent is knocked out and unable to get up before the referee counts to ten seconds (a knockout, or KO) or if the opponent is deemed too injured to continue (a Technical Knockout, or TKO), if an opponent is disqualified for breaking a rule, or if there is no stoppage of the fight before an agreed number of rounds, a winner is determined either by the referee\'s decision or by judges\' scorecards. A boxing match typically consists of a determined number of three-minute rounds. The birth hour of boxing as a sport may be its acceptance by the ancient Greeks as an Olympic game as early as 688 BC. Modern boxing evolved in Europe, particularly Great Britain. Karate is a martial art developed in the Ryukyu Islands in what is now Okinawa, Japan. It was developed from indigenous fighting methods called te and Chinese kenpô. Karate is a striking art using punching, kicking, knee and elbow strikes, and open-handed techniques such as knife-hands. Grappling, locks, restraints, throws, and vital point strikes are taught in some styles. A karate practitioner is called a karateka. Karate was developed in the Ryukyu Kingdom prior to its 19th-century annexation by Japan. It was brought to the Japanese mainland in the early 20th century during a time of cultural exchanges between the Japanese and the Ryukyuans. In 1922 the Japanese Ministry of Education invited Gichin Funakoshi to Tokyo to give a karate demonstration. In 1924 Keio University established the first university karate club in Japan and by 1932, major Japanese universities had karate clubs. For many practitioners, karate is a deeply philosophical practice. Athletic Prowess can be defined as superior atheletic skill, ability, strength, courage, or daring. Athletics is an exclusive collection of sporting events that involve competitive running, jumping, throwing, and walking. The most common types of athletics competitions are track and field, road running, cross country running, and race walking. The simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most commonly competed sports in the world. Organised athletics are traced back to the Ancient Olympic Games from 776 BC, and most modern events are conducted by the member clubs of the International Association of Athletics Federations. The athletics meeting forms the backbone of the modern Summer Olympics, and other leading international meetings include the IAAF World Championships and World Indoor Championships, and athletes with a physical disability compete at the Summer Paralympics and the IPC Athletics World Championships.
