Kickboxing is a group of martial arts and 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. Kickboxing has a number of different rulesets. For example, American Kickboxing restricts to strikes using punches and higher kicks; whereas some other arts often regarded as "kickboxing" allow low kicks and even knee strikes, elbows, and grappling maneuvers. All forms of kickboxing use an identical scoring system, however. A winner is declared during the bout if there is a submission (fighter quits or fighter's corner throws in the towel), knockout (KO), or referee stoppage (technical knockout, or TKO).
