B.J.J.
Brazilian Jiu-Jitsu is a martial art, combat sport and a form of self-defense that focuses on grappling and especially ground fighting. The art was derived from the Japanese martial art of Kodokan judo in the early 20th century, which was itself developed from a number of schools of Japanese jujutsu in the 19th century.
It promotes the principle that a smaller, weaker person can successfully defend them self against a bigger, stronger assailant by using leverage and proper technique — most notably by applying joint-locks and chokeholds to defeat the other person. Brazilian Jiu Jitsu can be trained for sport grappling tournaments and mixed martial arts (MMA) competition or self-defense. Sparring (commonly referred to as 'rolling') and live drilling play a major role in training, and a premium is placed on performance, especially in competition.
Brazilian jiu jitsu is done while wearing a gi. A Brazilian jiu jitsu gi is the kimono uniform worn in traditional BJJ grappling. Similar to a judo gi, a Brazilian jiu-jitsu gi is made of heavy-weave fabric and designed to stand up to the rigorous pulling, lifting, and throwing actions of martial arts, BJJ, grappling, and submission technique
NO GI , otherwise known as submission grappling, or Combat wrestling in Japan, is a formula of competition and a general term describing the aspect of martial arts and combat sports that focus on clinch and ground fighting with the aim of obtaining a submission using submission holds.
The sport of submission arts wrestling brings together techniques from Folk American Wrestling (Catch-as-catch-can), Luta Livre Esportiva, Freestyle Wrestling, Judo and Sambo. Submission fighting as an element of a larger sport setting is very common in mixed martial arts, Pankration, catch wrestling and others. Submission wrestlers or grapplers usually wear shorts, skin-sticky clothing such as Rash guards, speedos and mixed short clothes so they do not rip off in combat.
BJJ Grappling vs. Submission Wrestling: Major Differences
The difference between BJJ grappling and no-gi submission grappling is in the grips. In the stand-up game, the grips provided by the Brazilian jiu jitsu gi allow for many judo-style throwing and submission techniques, while no-gi submission wrestling takedowns resemble those of Greco-roman and freestyle wrestling. Grips also come into play on the ground. Where the BJJ grappling ground game is slow, measured, and technical, no-gi combat submission wrestling moves tend to be more fluid and fast-paced.
