In East Asian martial arts, the black belt is associated with expertise, but may indicate only competence, depending on the martial art. The use of colored belts is a relatively recent invention dating from the 1880s.

A focus mitt is a padded target attached to a glove and usually used in training boxers and other combat athletes.

Footwork is a martial arts and combat sports term for the general usage of the legs and feet in stand-up fighting. Footwork involves keeping balance, closing or furthering the distance, controlling spatial positioning, and/or creating additional momentum for strikes.
In kickboxing and mixed martial arts (MMA), "freak show fight" is an idiom for a bout featuring a deep disparity in skill, experience or weight between the fighters. This kind of matchup was common in the early period of mixed martial arts history, but it has become increasingly rare due to the regulation of athletic commissions and the implementation of official weight classes. However, freak show fights remain particularly associated in popular culture to Japanese promotions, where they are still occasionally hosted. Those bouts are usually a source of controversy among pundits, as they are perceived to elevate spectacle over true competition, but they retain a measure of acceptance among wide audiences due to their entertainment value.

A jab is a type of punch used in the martial arts. Several variations of the jab exist, but every jab shares these characteristics: while in a fighting stance, the lead fist is thrown straight ahead and the arm is fully extended from the side of the torso. This process also involves a quick turn of the torso. It is an overhand punch; at the moment of impact, the pronated fist is generally held in a horizontal orientation with the palm facing the ground.
A knockout is a fight-ending, winning criterion in several full-contact combat sports, such as boxing, kickboxing, muay thai, mixed martial arts, karate, some forms of taekwondo and other sports involving striking, as well as fighting-based video games. A full knockout is considered any legal strike or combination thereof that renders an opponent unable to continue fighting.

A liver shot or liver punch is a punch, kick, or knee strike to the right side of the ribcage that damages the liver. Blunt force to the liver can be excruciatingly painful, and an especially effective shot will incapacitate a person at once. Thus, in combat sports, liver shots often result in technical knockouts (TKOs).
Pressure points derive from the meridian points in Traditional Chinese Medicine and Indian Ayurveda and Siddha medicine, and the field of martial arts, and refers to an area on the human body that may produce significant pain or other effects when manipulated in a specific manner.

A red belt is one of several colored belts used in some martial arts to either denote rank or differentiate opponents in a competition. Like the more commonly known Black Belt, its use varies between arts, with most using it for the style founder, Grandmaster or other high rank, while others use it as the immediately pre–black belt rank or even to denote a beginner who holds no rank. In some schools, especially those with lineage related to Kodokan Judo, a red belt signifies ninth or tenth degree Dan rank, the highest ranks attainable.

Repechage is a practice in series competitions that allows participants who failed to meet qualifying standards by a small margin to continue to the next round. A well known example is the wild card system.

In martial arts and combat sports, stand-up fighting is hand-to-hand combat between opponents in a standing position, as distinguished from ground fighting. Clinch fighting is stand-up grappling. Fighters employ striking, including striking combinations, using either body parts or mêlée weapons, to incapacitate or injure the opponent. Combatants use blocking techniques to block the opponent's attacks.

Street fighting is hand-to-hand combat in public places, between individuals or groups of people. Unlike sport fighting, a street fight might involve weapons, multiple opponents, and no rules. The venue is usually a public place and the fight sometimes results in serious injury or occasionally even death. Some street fights can be gang-related.

A striking combination is a combination of strikes performed in rapid succession, usually from a stand-up position. If the combination includes only punches, it is called a punching combination, and if it includes only kicks, it is called a kicking combination.

A submission is a combat sports term for yielding to the opponent, and hence resulting in an immediate defeat. The submission – then also referred to as a "tap out" or "tapping out" – is often performed by visibly tapping the floor or the opponent with the hand or in some cases with the foot, or by saying the word 'tap' to signal the opponent and/or the referee of the submission. In some combative sports where the fighter has cornermen, the cornerman can also stop the fight by "throwing in the towel", which may count as a submission.

Submission Wrestling, also known as Submission Fighting, Submission grappling, Sport grappling, or Combat wrestling, is a form of competition and a general term for martial arts and combat sports that focus on clinch and ground fighting with the aim of obtaining a submission through the use of submission holds. The term "submission wrestling" usually refers only to the form of competition and training that does not use a gi, or "combat kimono", of the sort often worn with belts that establish rank by color, though some may use the loose trousers of such a uniform, without the jacket. Not using a gi has a major impact on the sport : there are many choke techniques which make use of the lapels of the gi, thus rendering them un-usable and grappling in general becomes more difficult when the opponent doesn't have a gi to grab hold of.
