MMA Rules

MMA Pound for Pound present The rules for modern mixed martial arts competitions have changed significantly since the early days of vale tudo, Japanese shoot wrestling, and UFC 1, and even more from the historic style of pankration. As the knowledge about fighting techniques spread among fighters and spectators, it became clear that the original minimalist rule systems needed to be amended. The main motivations for these rule changes were protection of the health of the fighters, the desire to shed the image of “barbaric, no rules, fighting-to-the-death” matches, and being recognised as a sport.

The new rules included the introduction of weight classes; as knowledge about submissions spread, differences in weight had become a significant factor. There are 9 different weight classes. These 9 weight classes include flyweight (up to 125 lb / 57 kg), bantamweight (126–135 lb / 61 kg), featherweight (136–145 lb / 66 kg), lightweight (146–155 lb / 70 kg), welterweight (156–170 lb / 77 kg), middleweight (171–185 lb / 84 kg), light heavyweight (186–205 lb / 93 kg), heavyweight (206–265 lb / 120 kg), and some organizations even go on to have a super heavyweight which is anything heavier than 265 pounds (120 kg).

Small, open-fingered gloves were introduced to protect fists in punches, reduce the occurrence of cuts (and stoppages due to cuts) and encourage fighters to use their hands for striking to allow more captivating matches. Time limits were established to avoid long fights with little action where competitors conserved their strength. Matches without time limits also complicated the airing of live events. The time limits in most professional fights are three 5 minute rounds, and championship fights are normally five 5 minute rounds. Similar motivations produced the “stand up” rule, where the referee can stand fighters up if it is perceived that both are resting on the ground or not advancing toward a dominant position.

Gloves were first mandatory in Japan’s Shooto promotion and were later adopted by the UFC as it developed into a regulated sport. Most professional fights have the fighters wear 4 oz gloves with little protection, whereas amateurs are required to wear a slightly heavier 6 oz glove for somewhat little more protection for the hands and wrist. In the U.S., state athletic and boxing commissions have played a crucial role in the introduction of additional rules because they oversee MMA in a similar way to boxing. Smaller shows may use more restrictive rules because they have less experienced fighters. In Japan and Europe, there is no regulating authority over competitions, so these organizations have greater freedom in rule development and event structure.

Many U.S. states have a “no elbow policy” for amateurs to help protect the young fighters from serious injury by cuts or concussions. The use of a “12-6” elbow has been banned by several organizations along with restrictions on the use of knees to a downed opponent, dictated by one person having a hand, arm, or knee on the ground. Knees to the head of a grounded opponent is allowed in Japanese MMA. Headbutts are also widely prohibited because they require little effort and can quickly open cuts that might cause a fight to be stopped due to injury rather than because there is a winner.
