Kickboxing is a group of stand-up combat sports based on kicking and punching, historically developed from karate mixed with 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.
