Mixed martial arts
Mixed Martial Arts is a full contact combat sport that allows the use of both striking and grappling techniques, both standing and on the ground, including boxing, wrestling, Brazilian jiu-jitsu, muay Thai, kickboxing, karate, judo and other styles. The roots of modern mixed martial arts can be...

competitions have evolved since the early days of vale tudo

. As the knowledge about fighting techniques spread among fighters and spectators, it became clear that the original minimalist rule systems needed to be amended. As rules evolved and regulations added, different branches of mixed martial arts have emerged, with differences between the different rulesets dictating different strategies. Similarly, shoot wrestling

, expanded their rulesets to integrate elements of vale tudo into their sport. However, for the most part, fighters accustomed to one ruleset can easily acclimate to a different ruleset, as the basics of fighting remain largely the same.

The most prevalent rule-set in the world being used currently is the Unified Rules of Mixed Martial Arts, a set of rules that has been adopted by all state athletic commissions in the United States that regulate mixed martial arts and is used most notably in the Ultimate Fighting Championship

, and have been adopted by other promotions and jurisdictions worldwide. Other notable sets include Shooto's, which were the first to mandate padded gloves, and PRIDE rules, after PRIDE Fighting Championships, which were also adopted by other promotions worldwide.

Evolution

Some main motivations for these rule changes included:
  • Protection of the health of the fighters: This goal was partially motivated to clear the stigma of "barbaric, no rules, fighting-to-the-death" matches that MMA obtained because of its vale tudo and no holds barred roots. It also helps athletes avoid injuries which would otherwise hamper the training regimens that improve skill and ability and lead to better fights in the future.
  • Providing spectacle for spectators.


Weight classes emerged when knowledge about submission holds spread. When more fighters became well-versed in submission techniques and avoiding submissions

Headbutt
Headbutt
A headbutt is a strike with the head, typically involving the use of robust parts of the cranium as areas of impact. Effective headbutting revolves around striking a sensitive area with a less sensitive area, such as striking the nose of an opponent with the forehead...

s were prohibited because it was a technique that required little effort and could quickly turn the match into a bloody mess. Headbutting was common among wrestlers because their skill in takedowns allowed them to quickly transfer bouts to the ground where they could assault opponents with headbutts while not being required to alter their position.

Small, open-finger gloves
MMA gloves
MMA gloves or grappling gloves are small, open-fingered gloves used in mixed martial arts bouts. They usually have around 4-6 oz of padding and are designed to provide some protection to the person wearing the glove, but leave the fingers available for grappling maneuvers such as clinch fighting...

 were introduced to protect fists in punches while still allowing for effective grappling. Gloves were first mandatory in Japan's Shooto league, but are now mandatory in matches for nearly every promotion. Although some fighters may have well conditioned fists, others may not. The small bones in an unprotected and unconditioned fist are prone to break when it hits a torso or forehead with power. Gloves also reduce the occurrence of cuts (and stoppages due to cuts) and encourage fighters to use their hands for striking, both of which enable more captivating matches.

Time limits were established to avoid long fights on the ground with little perceivable action. No time limit matches also complicated the airing of live events. Similar motivations produced the "stand up" rule, where the referee can stand fighters up if it is perceived both are resting on the ground or are not advancing toward a dominant position.

Ways to victory

  • Knockout
    Knockout
    A knockout is a fight-ending, winning criterion in several full-contact combat sports, such as boxing, kickboxing, Muay Thai, mixed martial arts, Karate and others sports involving striking...

     (KO): as soon as a fighter becomes unconscious due to strikes, his opponent is declared the winner. As MMA rules allow ground fighting, the fight is stopped to prevent further injury to an unconscious fighter.
  • Technical Knockout (TKO)
    • Referee Stoppage: the referee may stop a match in progress if:
      • a fighter becomes dominant to the point where the opponent is unable to intelligently defend himself from attacks, which may occur as quickly as a few seconds;
      • a fighter appears to have developed a severe injury: the referee will call for a time out if a fighter's ability to continue is in question as a result of apparent injuries, such as a large cut. The ring doctor will inspect the fighter and stop the match if the fighter is deemed unable to continue safely, rendering the opponent the winner. However, if the match is stopped as a result of an injury from illegal actions by the opponent, either a disqualification or no contest will be issued instead.
    • Corner stoppage: a fighter's corner men may announce defeat on the fighter's behalf by throwing in the towel during the match in progress or between rounds.
    • Retirement: if a fighter feels unable to continue after the conclusion of a round, s/he may inform or have the corner inform the referee that s/he forfeits the match to his opponent.
  • Submission
    Submission (combat sport term)
    A submission is a combat sports term for yielding to the opponent, and hence resulting in an immediate defeat...

    : a fighter may admit defeat during a match by:
    • a tap on the opponent's body;
    • a tap on the mat or floor;
    • verbal announcement.
  • Technical Submission: a referee may intervene and call a stop to the contest when:
    • a fighter appears to be unconscious from a grappling hold;
    • a fighter appears to have suffered a serious injury from a grappling hold.
  • Decision: if the match goes the distance, then the outcome of the bout is determined by three judges. The judging criteria are organization-specific.
    • Unanimous Decision: if all three judges on the panel score a bout unanimously in favor of one fighter
    • Split Decision: if two judges on the panel score a bout in favor of one fighter, with one judge scoring the bout in favor of the other
    • Majority Decision: if two judges on the panel score a bout in favor of one fighter, with one judge scoring the bout a draw
    • Draw: if all three judges on the panel score a bout unanimously in favor of neither fighter.
    • Split Draw: if one judge on the panel score a bout in favor of one fighter, the second in favor of his opponent, and the third in favor of neither fighter
    • Majority Draw: if two judges score the bout a draw, with one judge scoring the bout in favor of one fighter
  • Technical Decision: if a fighter behind or even on points commits an intentional foul during the course of the match, and the opponent is unable to continue due to the injury or injuries inflicted by the foul at any subsequent point in the fight, the match is stopped and awarded to injured fighter
  • Technical Draw: if a fighter ahead on points commits an intentional foul during the course of the match, and the opponent is unable to continue due to the injury or injuries inflicted by the foul at any subsequent point in the fight, the match is stopped and awarded to injured fighter
  • Forfeit: a fighter or his representative may forfeit a match prior to the beginning of the match, thereby losing the match.
  • Disqualification: a "warning" will be given when a fighter commits a foul or illegal action or does not follow the referee's instruction. Three warnings will result in a disqualification. Moreover, if a fighter is injured and unable to continue due to a deliberate illegal technique from his opponent, the opponent will be disqualified.
  • No Contest: in the event that both fighters commit a violation of the rules, or a fighter is unable to continue due to an injury from an accidental illegal technique, the match will be declared a "No Contest".

Unified Rules of Mixed Martial Arts

In April 2000, the California State Athletic Commission
California State Athletic Commission

, voted unanimously in favor of regulations that later became the foundation for the Unified Rules of Mixed Martial Arts. However when the legislation was sent to California's capital for review, it was determined that the sport fell outside the jurisdiction of the CSAC, rendering the vote superfluous.

In September 2000, the New Jersey State Athletic Control Board

The New Jersey State Athletic Control Board regulates all contests and exhibitions of unarmed combat within the state of New Jersey, including licensure and supervision of promoters, boxers, kickboxers, mixed martial arts fighters, seconds, ring officials, managers, and matchmakers...

 began to allow mixed martial arts promoters to conduct events in New Jersey. The intent was to allow the NJSACB to observe actual events and gather information to establish a comprehensive set of rules to effectively regulate the sport.

On April 3, 2001, the NJSACB held a meeting to discuss the regulation of mixed martial arts events. This meeting attempted to unify the myriad of rules and regulations which have been utilized by the different mixed martial arts organizations. At this meeting, the proposed uniform rules were agreed upon by the NJSACB, several other regulatory bodies, numerous promoters of mixed martial arts events and other interested parties in attendance. At the conclusion of the meeting, all parties in attendance were able to agree upon a uniform set of rules to govern the sport of mixed martial arts.

The rules adopted by the NJSACB have become the de facto standard set of rules for professional mixed martial arts across North America. All state, provincial, & municipal athletic commissions that regulate mixed martial arts have assimilated these rules into their existing unarmed combat competition rules and statutes. For a promotion to hold mixed martial arts events in a sanctioned venue, the promotion must abide by the commission's body of rules.

On July 30, 2009, a motion was made at the annual meeting of the Association of Boxing Commissions

PRIDE Fighting Championships (defunct)

Historically, PRIDE's rules differed between main PRIDE events and Bushido events. However, it was announced on November 29, 2006, that Bushido events would be discontinued. When holding events in the US, PRIDE abided by the Unified Rules, but added the prohibition against elbows to the head.

Rounds

The first round is ten minutes in duration and the second and third rounds are five minutes in duration. There is a two minute rest period between each round. Grand Prix matches are two rounds in length if more than one round is scheduled on one night.

Attire

PRIDE allows fighters latitude in their choice of attire but open finger gloves, a mouthguard and a protective cup are mandatory. It is within a fighter's discretion to tape

 parts of their body but you can not wear a gi top, gi pants, wrestling shoes, kneepads, elbow pads, shin guards or ankle supports.

Judging criteria

If the match reaches its time limit then the outcome of the bout is determined by the three judges. The fight is scored in its entirety and not round-by-round. After the conclusion of the bout, each judge must decide a winner. Matches cannot end in a draw. A decision is made according to the following criteria in this order of priority:
  1. the effort made to finish the fight via KO or submission,
  2. damage given to the opponent,
  3. standing combinations and ground control,
  4. takedowns and takedown defense,
  5. aggressiveness, and
  6. weight (in the case that the weight difference is 10 kg/22 lb or more).


If a fight is stopped on advice of the ring doctor after an accidental but illegal action, e.g., a clash of heads, and the contest is in its second or third round, the match will be decided by the judges using the same criteria.

Legal techniques

PRIDE allowed the following techniques:
  • Stomps to a grounded opponent.
  • Soccer kicks to the head of a grounded opponent.
  • Knees to the head of a grounded opponent.

Fouls

In addition to the common fouls, PRIDE Fighting Championships considers elbow strikes

An elbow strike is a strike with the point of the elbow, the part of the forearm nearest to the elbow, or the part of the upper arm nearest to the elbow...

 to the head and face to be fouls.

In the event that a fighter is injured by illegal actions, then at the discretion of the referee and ring doctor, the round is resumed after enough time has been given for the fighter to recover. If the match cannot be continued due to the severity of the injury then the fighter who perpetrated the action will be disqualified.

General conduct

  • If both fighters are on the verge of falling out of the ring or become entangled in the ropes, the referee will stop the action. The fighters must immediately stop their movements and will then be repositioned in the center of the ring in the same position. Once they are comfortably repositioned, they resume at the referee's instruction.
  • If fighters commit the following actions, they shall be given a yellow card by officials: Stalling or failure to initiate any offensive attack, making no attempt to finalize the match or damage the opponent, and holding the opponent's body with the arms and legs to produce a stalemate. A yellow card results in a 10% deduction/fine of the fighter's fight purse.

Bushido rules

PRIDE Bushido events instituted distinct variations to the full PRIDE rules:
  • Bushido bouts consist of two rounds; the first lasting ten minutes and the second lasting five. Intermissions between each round remain two minutes in length.
  • In full PRIDE rules, a total of three yellow cards results in a red card (disqualification). In Bushido, yellow cards can be given out in an unlimited number without disqualification.


PRIDE discontinued Bushido events in late-2006 and their rules were last used for lightweight and welterweight fights at PRIDE Shockwave 2006

  • The C level rules require headgear to be worn and prohibit striking on the ground.
  • In case of a knockdown (when any part of a competitor's body touches the mat solely as the result of a strike) the referee will perform a 10-count.

  • Does not use judges. The fight is declared a draw if there is no KO, TKO, Submission.

    , with an eight man tournament. However, the final matches are not decided on the same evening, but at later events.

Cage or ring

MMA is often referred to as "cage fighting" in the US as it is associated with the UFC's octagonal caged fighting area. Most major MMA promotions in the US, Canada and Britain use the "cage" as a result of directly evolving from the first UFC events. There are variations on the cage such as replacing the metal fencing with a net, or using a different shape for the area other than an octagon, as the term "The Octagon" is trademarked by the UFC (though the 8-sided shape itself is not trademarked). In Japan, Brazil and some European countries such as the Netherlands an area similar to a standard boxing ring

.

The choice of cage or ring is more than aesthetic however, as it impacts the type of strategies that a fighter can implement. For example, a popular and effective strategy in a cage is to pin an opponent into the area where the fence meets the mat, and then pummel him with strikes. Randy Couture

 is well known for this tactic. Defensively, the cage is often used as support to fend off take-down attempts, or as a support to get from underneath and opponent (known as "walking up the cage"). These positions are not possible in a roped ring. On the other hand, the roped ring can result in entangled limbs and fighters falling through the ropes, requiring the referee to sometimes stop the fight and reposition the fighters in the center, as well as carrying the possibility for either fighter to sustain an injury. In either a cage or ring, a fighter is not allowed to grab the fence or ropes. Some critics feel that the appearance of fighting in a cage contributes to a negative image of MMA in popular media.

Government regulation

In the U.S., state athletic and boxing commissions have played a crucial role in the introduction of safety rules because they oversee MMA in similar ways as they do for boxing. Small shows usually use more restrictive rules because they have less experienced fighters who are looking to acquire experience and exposure that could ultimately lead them to getting recruited into one of the larger, better paying promotions.
In Japan and Europe, there is no regulating authority over MMA competitions, so these organizations have greater freedom in rules development and event structure.
In general, a balanced set of rules with some organization-specific variances has been established and is widely used, and major rule changes are unlikely, allowing for fighters in one organization to transition to others easily.
