Grappling: In hand-to-hand combat, grappling is a close fighting technique used to gain a physical advantage such as improving relative position, or causing injury to the opponent. Grappling covers techniques used in many disciplines, styles and martial arts that are practiced both as combat sports and for self-defense.
Grappling most commonly does not include striking or the use of weapons. However, some fighting styles or martial arts known especially for their grappling techniques teach tactics that include strikes and weapons either alongside grappling or combined with it.[1]
Brazilian jiu-jitsu is a martial art and combat sport system that focuses on grappling with particular emphasis on ground fighting. Brazilian jiu-jitsu was developed from Kodokan judo ground fighting (newaza) fundamentals that were taught by a number of Japanese individuals including Takeo Yano, Mitsuyo Maeda, Soshihiro Satake, and Isao Okano. Brazilian jiu-jitsu eventually came to be its own combat sport when mainstream Judo grew towards becoming an Olympic sport;[8] as well as through the innovations, practices, and adaptation of judo, jujutsu and wrestling through Carlos and Hélio Gracie (who passed their knowledge on to their extended family) as well as other instructors (who were likely students of the Judoka Maeda, such as Luiz França, and their later successors in Brazil and elsewhere).
Aikido is a modern Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs. Ueshiba's goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.[1][2] Aikido is often translated as "the way of unifying (with) life energy"[3] or as "the way of harmonious spirit".[4]
Judo ("gentle way") was created as a physical, mental and moral pedagogy in Japan, in 1882, by Jigoro Kano (嘉納治五郎). It is generally categorized as a modern martial art which later evolved into a combat and Olympic sport. Its most prominent feature is its competitive element, where the objective is to either throw or takedownan opponent to the ground, immobilize or otherwise subdue an opponent with a pin, or force an opponent to submit with a joint lock or a choke. Strikes and thrusts by hands and feet as well as weapons defenses are a part of judo, but only in pre-arranged forms (kata, 形) and are not allowed in judo competition or free practice (randori, 乱取り). A judo practitioner is called a judoka.
Hapkido (UK: /ˌhæpkiːˈdoʊ/ HAP-kee-DOH,[1] US: /hɑːpˈkiːdoʊ/ hahp-KEE-doh,[2] also spelled hap ki do or hapki-do; from Korean hapgido [hap̚.k͈i.do]) is a highly eclectic Korean martial art. It is a form of self-defense that employs joint locks, grappling, and throwing techniques similar to those of other martial arts, as well as kicks, punches, and other striking attacks. It also teaches the use of traditional weapons, including knife, sword, rope, ssang juhl bong (nunchaku), cane (ji pang ee), short stick (dan bong), and middle-length staff (joong bong, gun (analogous to the Japanese jō), and bō (Japanese)), which vary in emphasis depending on the particular tradition examined.
Those are SOME fighting styles.
