Submission wrestling in the context of "Marco Ruas"

Wrestling is a martial art, combat sport, and form of entertainment that involves grappling with an opponent and striving to obtain a position of advantage through different throws or techniques, within a given ruleset. Wrestling involves different grappling-type techniques, such as clinch fighting, throws and takedowns, joint locks, pins, and other grappling holds. Many different wrestling techniques have been incorporated into martial arts, combat sports, and military systems.

Wrestling comes in different forms, the most popular being professional wrestling, which is a form of athletic theatre. Other legitimate competitive forms include Greco-Roman, freestyle, judo, sambo, folkstyle, catch, shoot, luta livre, submission, sumo, pehlwani, shuai jiao, and more. Wrestling first appeared in the ancient Olympic Games as an event during the 18th Olympiad in 708 BC. There are a wide range of styles with varying rules, with both traditional historic and modern styles. The term "wrestling" in Modern English originated from the late Old English term wræstlunge.

A leglock is a joint lock that is directed at joints of the leg such as the ankle, knee or hip joint. A leglock which is directed at joints in the foot is sometimes referred to as a foot lock and a lock at the hip as a hip lock. Leglocks are featured, with various levels of restrictions, in combat sports and martial arts such as Sambo, Brazilian Jiu-Jitsu, catch wrestling, mixed martial arts, Shootwrestling and submission wrestling, but are banned in some sports featuring joint locks such as judo. The technique has been seen across a wide range of different combat sports and is reportedly over 2,500 years old, having been seen in the lost art of Pankration in the original Olympic Games.

As with other jointlocks, leglocks are more effective with full body leverage. Some attack the large joints of the knee or hip and involve utilizing leverage to counteract the larger muscle groups, while others directly attack ligaments in the knee or the smaller joint of the ankle. Leglocks can involve control positions such as the inside leg triangle or leg knot to maintain control while applying the attack or transitioning between two attacks, though they and some other control positions are banned in Brazilian Jiu-jitsu competition. Some other leglock control positions have been adopted into modern BJJ and submission grappling competitions as "guards" such as the snake guard, one-legged X-guard, and 50/50 Guard, where they are used for both leglocks and to reverse into dominant positions from the bottom.
