Brazilian Jiu-Jitsu is a martial art, combat sport, and a self defense system 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,[1][2] which was itself developed from a number of schools (or Ryu) of Japanese jujutsu in the 19th century. It teaches that a smaller, weaker person can successfully defend 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 (gi and no-gi) and mixed martial arts (MMA) competition or self defense.[3] 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.

Eskrima, Arnis and Kali refer to a class of Filipino martial arts that emphasize weapon-based fighting with sticks, blades and improvised weapons. Although training starts with weapons, empty hand techniques, trapping and limb destruction are core parts of these arts as the weapon is considered merely an extension of the body. Eskrima and Arnis are the most common among the many names often used in the Philippines today to refer to these arts.

The teaching of the basic skills in Eskrima are traditionally simplified. With limited time to teach intricate moves, only techniques that were proven effective in battle and could easily be taught en masse were used. This allowed villagers, generally not professional soldiers, a measure of protection against other villages, as well as foreign invaders. This philosophy of simplicity is still used today and is the underlying base of eskrima. Because of this approach, eskrima and the Filipino martial arts in general are often mistakenly considered to be "simple". However, this refers only to its systematization, not effectiveness. To the contrary, beyond the basic skills lies a very complex structure and a refined skillset that takes years to master.

Mixed Martial Arts (MMA) is a full contact combat sport that allows a wide variety of fighting techniques and skills, from a mixture of martial arts and non-martial arts traditions, to be used in competitions. The rules allow the use of both striking as well as grappling techniques, both while standing and on the ground. Such competitions allow martial artists of different backgrounds to compete.

The roots of modern mixed martial arts can be traced back to various mixed style contests that took place throughout Europe, Japan and the Pacific Rim during the early 1900s. The combat sport of Vale Tudo that had developed in Brazil from the 1920s was brought to the United states by the Gracie family in 1993 with the founding of the Ultimate Fighting Championship. Professional MMA events had also been held in Japan by Shooto starting back in 1989. In due course the more dangerous Vale Tudo style bouts of the early UFCs were made safer with the implementation of additional rules, leading to the popular regulated form of MMA seen today. Originally promoted as a competition with the intention of finding the most effective martial arts for real unarmed combat situations, competitors were pitted against one another with minimal rules.[5] Later promoters adopted many additional rules aimed at increasing safety for competitors and to promote mainstream acceptance of the sport.[6]

Muay Thai is a hard martial art from Thailand. It is similar to other Indochinese styles of kickboxing, namely pradal serey from Cambodia, tomoi from Malaysia, lethwei from Myanmar and Muay Lao from Laos. Descended from muay boran, Muay Thai is Thailand's national sport.[7][8]

The word muay derives from the Sanskrit mavya and Thai comes from the word Tai. Muay Thai is referred to as the "Art of Eight Limbs" or the "Science Of Eight Limbs" because it makes use of punches, kicks, elbows and knee strikes, thus using eight "points of contact", as opposed to "two points" (fists) in Western boxing and "four points" (hands and feet) used in sport-oriented martial arts.[9] A practitioner of Muay Thai is known as a nak muay. Western practitioners are sometimes called nak muay farang meaning foreign boxer.[10]
