MMA rules explained: what is and isn’t allowed?

MMA has clear competition rules. Strikes, kicks, clinch work, takedowns, ground techniques, and submissions can all be combined in a single bout, but that does not mean “anything goes.” The rules determine which techniques are permitted, how a round is scored, when an opponent is considered grounded, and which actions may result in a warning, a points deduction, or disqualification.

Moreover, there is no single rulebook that is applied literally the same way everywhere in the world. The Unified Rules of MMA form the most widely used basis for professional MMA, but countries, commissions, federations, and promoters may apply additional or different provisions. In the Netherlands, the Dutch Martial Arts Federation (NVB) uses a uniform set of rules largely based on the Unified Rules, with additional restrictions for amateurs. Anyone planning to compete should therefore always check the current regulations of the relevant federation or organization.

How do MMA rules work in practice?

MMA stands for Mixed Martial Arts and combines three key phases of combat: stand-up fighting, clinching, and ground fighting. For example, a fighter can start with boxing or kickboxing, execute a takedown from the clinch, and continue on the ground with control, ground-and-pound, or a submission.

This versatility distinguishes MMA from sports in which only one aspect of fighting is central. If you first want to understand how MMA compares with ground-focused disciplines, also read our explanation of the difference between MMA, BJJ and grappling.

During the bout, the referee monitors safety and the application of the rules. Judges become involved when a fight is not stopped prematurely. They score each round separately.

How long does an MMA fight last?

The round format depends on the level and organization. Under the current Dutch NVB regulations for adults, the following formats apply:

• Amateur MMA: three three-minute rounds; five three-minute rounds for a title fight.
• Professional MMA: three five-minute rounds; five five-minute rounds for a title fight.
• Rest: one minute between rounds.

International organizations may use their own competition formats. Therefore, “an MMA fight always lasts three five-minute rounds” is too simplistic: that is a common professional format, but not a universal rule for every amateur, youth, or title bout.

How does scoring work in MMA?

When there is no KO, TKO, submission, or other early finish, the judges decide. Many MMA rulesets use the 10-point must system. The winner of a round normally receives 10 points; the other fighter usually receives 9, or fewer when the difference in the round is significant.

Under the current Dutch rules, judges first look at the effectiveness of striking and grappling: what do punches, kicks, takedowns, positional attacks, and submissions actually achieve? Only when this does not provide enough distinction do effective aggression, followed by control of the fighting area, come into consideration.

That is why a takedown alone is not automatically enough to win a round. A takedown that leads to control, damage, a submission threat, or further effective attacks carries different weight from a takedown followed by virtually nothing. The same applies to forward pressure: aggression counts mainly when it is also effective.

What do 10-9 and 10-8 mean?

A 10-9 is the normal score for a round in which one fighter has a recognizable advantage. A 10-8 is associated with a round featuring much clearer dominance and impact. A 10-7 score can exist under certain rules, but it is exceptional and applies to highly one-sided rounds in which a stoppage was close.

Which techniques are allowed in MMA?

Exactly which techniques are legal depends on the ruleset and the position of both fighters. In professional MMA, many striking and grappling techniques are generally permitted, including:

• punches and many types of kicks;
• knees and, within the applicable rules, elbows;
• clinch work against the cage or in the center;
• takedowns, throws, and trips;
• positional control on the ground;
• ground strikes within the permitted target areas;
• chokes and various joint locks.

“Allowed” does not mean that a technique is legal in every situation. The position of a grounded opponent, the target area, and amateur or professional status may determine whether the same movement is permitted.

What is not allowed in MMA?

The common misconception that anything goes in MMA is incorrect. The current Dutch professional rules prohibit, among other things, headbutts, eye attacks, biting, spitting, hair pulling, attacks on the throat or groin, strikes to the spine or the back of the head, manipulation of small joints, grabbing the cage, and holding an opponent’s equipment.

Under the current Dutch regulations, knees and kicks to the head of a grounded opponent are also prohibited. Under this rule set, a fighter is considered grounded when, in addition to their hands or feet, another part of their body, such as a knee or elbow, is touching the ground.

Fouls can also arise from conduct unrelated to a specific technique, such as deliberately ignoring the referee’s instructions, attacking after the bell, or unsportsmanlike conduct.

What is the difference between amateur and professional MMA rules?

Amateur rules are often more restrictive to make the transition to competitive MMA more controlled. Under the current Dutch NVB regulations, additional prohibitions for amateurs apply alongside the general fouls. These include elbow strikes, knees to the head in the standing position, and heel hooks. Certain attacks on the knee and submissions targeting the spine are also prohibited.

That difference is important for athletes who watch professional fights online and then assume that exactly the same technique is legal in their first amateur bout. So never use footage from major promoters as a substitute for the competition rules that apply to your bout.

How can you win an MMA bout?

An MMA bout can end in several ways. The best-known are:

• KO: a fighter cannot safely continue after a legal attack.
• TKO: the referee, doctor, or sometimes the fighter’s corner stops the bout because continuing is unsafe or the fighter is no longer defending themselves adequately.
• Submission: a fighter taps out, verbally submits, or the referee intervenes when a choke or hold is successfully applied.
• Decision: the judges determine the winner when the scheduled rounds have been completed.
• Disqualification: a serious or decisive foul can result in a loss.

Depending on the circumstances, technical decisions, draws, or a no contest may also occur.

Are UFC rules the same as MMA rules?

No. The UFC is an MMA promoter, not a synonym for the sport itself. The UFC uses the Unified Rules as its basis, but MMA exists worldwide under various organizations and regulatory bodies. The application of definitions and specific techniques can also change when rules are updated.

That distinction may seem small, but it is important. In our guide UFC vs PFL, for example, you can read why two organizations can both offer MMA without being the same organizationally.

Competition rules are not the same as sparring rules

What is legal in an official competition does not necessarily have to be desirable or permitted during training. Gyms usually have their own rules regarding intensity, protective equipment, and techniques during sparring. The purpose of sparring is to develop technically with a training partner, not to reproduce a competition without restrictions.

If you are heading into your first sparring sessions, having good basic equipment helps. For that, check out our MMA gear checklist for your first sparring session.

What equipment do you use for MMA?

Competition organizations determine exactly which equipment is permitted or required during an official bout. In training, the choice is broader and depends on the type of drill. For example, MMA gloves offer more freedom of movement for grappling than traditional boxing gloves, but for certain striking or sparring drills, a coach may prescribe different gloves.

Common misconceptions about MMA rules

“Anything goes in MMA”

Incorrect. MMA has extensive rules covering permitted techniques, target areas, fouls, equipment, round times, and judging.

“A takedown always earns points”

Too simplistic. Judges evaluate the effectiveness of the grappling work. What results from a takedown can therefore be more important than merely the moment when someone goes to the ground.

“The UFC determines the rules for all MMA”

Incorrect. The Unified Rules are influential, but MMA has no single worldwide regulator that imposes exactly the same rules for every event.

“What professionals do, amateurs may do too”

Not necessarily. Amateur rule sets may prohibit additional techniques and use shorter rounds.

FAQ about MMA rules

Are you allowed to use elbows in MMA?

In professional MMA, elbow techniques are permitted under many rule sets, as long as they comply with the applicable technique and target-area rules. Under the current Dutch amateur rules, elbow strikes are prohibited. Always check the rules of the event.

Are you allowed to throw knees to the head in MMA?

That depends on the level and position. Under the current Dutch professional rules, a knee to the head of a grounded opponent is prohibited. For Dutch amateurs, knees to the head are also not allowed during standing exchanges.

How many rounds does an MMA fight have?

Under the current Dutch rules, professionals normally fight three five-minute rounds and amateurs three three-minute rounds. Title fights may have five rounds. Other organizations and countries may use different formats.

How are MMA rounds scored?

Many rule sets use the 10-point must system. The winner of the round generally receives 10 points and the other fighter receives 9 or fewer. Effective striking and grappling come first; effective aggression and control become relevant afterward when the first criterion does not provide enough distinction.

Do you need to know the official MMA rules before fighting in a bout?

Yes. Training based on assumptions from professional fights is not enough. Discuss the current competition rules with your coach and check the rules of the federation, promoter, or commission under which your bout takes place.

Conclusion: MMA is versatile, but not without rules

The core of MMA is that striking and grappling come together in one match. Precisely because there are so many technical possibilities, clear rules are necessary. Therefore, understand not only which techniques you can perform, but also when they are legal, how judges assess effectiveness, and what differences exist between amateur and professional MMA. For recreational training, your coach’s guidelines take precedence; for an official bout, the current competition rules of the organization under which you fight always apply.
