World championship

A world championship is generally an international sports competition open to elite competitors from across the world, representing their nations, and winning such an event will be considered the highest or near highest achievement in the sport or contest.

The title is usually awarded through a combination of specific contests or, less commonly, ranking systems (e.g. the ICC Test Championship), or a combination of the two (e.g. World Triathlon Championships in Triathlon). This determines a 'world champion', who or which is commonly considered the best nation, team, individual (or other entity) in the world in a particular field, although the vagaries of sport ensure that the competitor recognised at the best in an event is not always the 'world champion' (see Underdog).

Certain sports do not have a world championship, instead they may organise a world cup competition, or they may organize both. Often, the use of the term cup or championship in this sense is just a choice of words. Some sports have multiple champions because of multiple organizations such as mixed martial arts, boxing and wrestling.

Kickboxing

Kickboxing (in Japanese キックボクシング kikkubokushingu) is a group of stand-up combat sports based on kicking and punching, historically developed from karate, Muay Thai, and Western boxing. Kickboxing is practiced for self-defense, general fitness, or as a contact sport.

Japanese kickboxing originated in the 1960s, with competitions held since then. American kickboxing originated in the 1970s and was brought to prominence in September 1974, when the Professional Karate Association (PKA) held the first World Championships. Historically, kickboxing can be considered a hybrid martial art formed from the combination of elements of various traditional styles. This approach became increasingly popular since the 1970s, and since the 1990s, kickboxing has contributed to the emergence of mixed martial arts via further hybridization with ground fighting techniques from Brazilian jiu-jitsu and Folk wrestling.

There is no single international governing body. International governing bodies include International Combat Organisation, World Association of Kickboxing Organizations, World Kickboxing Association, International Sport Karate Association, International Kickboxing Federation, World Sport Kickboxing Federation, among others. Consequently, there is no single kickboxing world championship, and champion titles are issued by individual promotions, such as K-1, Glory, SUPERKOMBAT, Lumpinee Boxing Stadium, among others. Bouts organized under different governing bodies apply different rules, such as allowing the use of knees or clinching, etc.

Martial arts

Martial arts are codified systems and traditions of combat practices, which are practiced for a variety of reasons: as self-defense, military and law enforcement applications; as competition, physical fitness, mental and spiritual development; as well as entertainment and the preservation of a nation's Intangible cultural heritage.

Although the term martial art has become associated with the fighting arts of eastern Asia, it originally referred to the combat systems of Europe as early as the 1550s. The term is derived from Latin, and means "arts of Mars", the Roman god of war. Some authors have argued that fighting arts or fighting systems would be more appropriate on the basis that many martial arts were never "martial" in the sense of being used or created by professional warriors.

Variation and scope

Martial arts may be categorized along a variety of criteria, including:
