What Is a Submission in MMA?

A submission is a method of victory in mixed martial arts where a fighter forces their opponent to concede defeat by applying a joint lock or choke hold. The defeated fighter signals their surrender—called "tapping out"—either by physically tapping the opponent or mat with their hand or foot, or by verbally telling the referee they wish to stop. A submission represents the ultimate test of technical proficiency, positional control, and the opponent's willingness to accept defeat rather than risk serious injury.

Unlike knockout victories that end fights through strikes, submissions are grappling-based finishes that place opponents in positions where continuing to resist would result in structural damage, unconsciousness, or worse. This creates a unique dynamic in MMA: the fighter in the submission hold must make a conscious decision to yield. The submission is complete the moment the opponent taps or verbally submits—the referee does not need to verify the legitimacy of the hold or wait for unconsciousness to occur.

How Submissions Differ from Other Victory Methods

MMA fights can end in several ways, and understanding how submissions fit into the broader landscape of fight finishes is crucial for both fighters and bettors.

The critical distinction is that a regular submission requires active participation from the losing fighter—they must recognize the danger and tap out. A technical submission occurs when the referee stops the fight because the fighter has been rendered unconscious or severely injured while trapped in a submission hold and cannot tap themselves. In both cases, the result is recorded as a submission victory.

How Do Submissions Work in MMA?

The Mechanics of Tapping Out

Tapping out is the fighter's safety mechanism in submission grappling. When trapped in a joint lock or choke that threatens injury or unconsciousness, the fighter signals surrender to the referee and their opponent. The tap must be visible and clear—a quick, deliberate contact against the opponent's body or the mat. Some referees are more lenient than others about recognizing taps, which has led to controversial finishes where fighters claim they tapped but the referee didn't see it.

There are three recognized ways to tap in professional MMA:

1. Physical tap on opponent — Striking the opponent's body, arm, or leg with the hand
2. Physical tap on mat — Striking the fighting surface with the hand or foot
3. Verbal submission — Verbally telling the referee or opponent "I tap" or "I submit"

In rare cases where a fighter has both arms trapped (such as in a rear-naked choke), they can tap with their foot. Verbal submissions are always valid, though they are less common than physical taps because fighters may not be able to speak clearly while being choked.

Why Fighters Tap Out

Fighters tap out for two primary reasons: to prevent injury or to escape the threat of unconsciousness. Joint locks (like armbars, kimuras, and heel hooks) create immediate pain and the threat of broken bones or torn ligaments. A fighter can feel the pressure building and knows that if they don't tap, their arm or leg will be permanently damaged. Chokes (like the rear-naked choke or triangle choke) restrict blood flow to the brain or airflow to the lungs, causing the fighter to either lose consciousness or face the threat of brain damage if the hold is maintained too long after they black out.

The decision to tap is deeply personal. Some fighters have exceptional pain tolerance and will endure significant discomfort before submitting. Others tap early to preserve their bodies for future fights. Professional fighters understand that tapping is not a sign of weakness—it's a strategic choice to live to fight another day. Refusing to tap when trapped in a submission hold is dangerous and can result in serious, permanent injury.

What Are the Two Main Types of Submissions?

All submissions in MMA fall into two broad categories: joint locks and chokes. Understanding the difference between these two submission families is essential for analyzing fighter matchups and predicting fight outcomes.

Joint Lock Submissions

A joint lock is a submission technique that manipulates an opponent's joints—typically the elbow, shoulder, knee, or ankle—beyond their normal range of motion. The attacker applies leverage to a joint, creating pain and the threat of structural damage. Joint locks are particularly effective because joints are designed to move only in specific directions; forcing them beyond those limits creates immediate danger.

Common joint lock submissions include:

• Armbar — The attacker traps the opponent's arm between their legs and hyperextends the elbow joint. This is one of the oldest and most fundamental submissions in grappling.
• Kimura — A shoulder lock where the attacker controls the opponent's arm and applies pressure to the shoulder joint, threatening to dislocate it or tear the rotator cuff.
• Americana — Similar to the kimura but applied from a different grip position, pinning the opponent's arm to the mat and hyperextending the shoulder.
• Heel Hook — One of the most dangerous submissions, the attacker controls the opponent's foot and applies pressure to both the ankle and knee simultaneously, threatening ligament damage.
• Kneebar — The attacker hyperextends the opponent's knee joint, threatening ACL and MCL damage.
• Ankle Lock — Pressure is applied to the ankle joint and Achilles tendon, causing pain and threatening ligament rupture.

Choke Submissions (Blood Chokes and Air Chokes)

A choke (also called a strangle) is a submission that restricts either blood flow to the brain or airflow to the lungs. Chokes are often more devastating than joint locks because they can cause unconsciousness within seconds and carry the risk of brain damage if maintained too long after the fighter loses consciousness.

There are two types of chokes:

Blood Chokes — These submissions compress the carotid arteries in the neck, restricting blood flow to the brain. The fighter loses consciousness within 5-10 seconds if the choke is not released. Blood chokes are generally considered safer than air chokes because unconsciousness happens before panic sets in, and the brain damage risk is lower if released immediately upon unconsciousness.

Air Chokes — These submissions restrict airflow to the lungs by compressing the trachea (windpipe). Air chokes take longer to cause unconsciousness (15-30 seconds) and are more uncomfortable, as the fighter experiences the sensation of suffocation. Air chokes carry a higher risk of tracheal damage if applied with excessive force.

Common choke submissions include:

• Rear-Naked Choke (RNC) — Applied from behind, the attacker wraps their arm around the opponent's neck, compressing both carotid arteries. This is the most common and highest-percentage submission in MMA.
• Triangle Choke — The attacker uses their legs to compress the opponent's neck and one arm, demonstrating how leverage can overcome size and strength differences.
• Guillotine Choke — Applied from the front, often when the opponent is bent forward, the attacker wraps their arm around the neck and compresses the carotid arteries.
• Arm-Triangle Choke — A hybrid technique using the opponent's arm and the attacker's arm to compress the neck, similar to a triangle choke but with arm pressure.
• D'Arce Choke — A head-and-arm choke applied when the opponent attempts an underhook, particularly effective in MMA when defending against takedowns.
• Anaconda Choke — An arm-triangle variation applied from a front headlock position with the opponent's arm trapped.

What's the Difference Between a Submission and a Technical Submission?

While both result in a submission victory, the distinction between a regular submission and a technical submission is important for understanding fight outcomes and rules.

Regular Submission (Tap Out)

A regular submission occurs when the fighter in the submission hold recognizes the danger and taps out—either by physically tapping or verbally submitting. The moment the tap is acknowledged by the referee, the fight ends, and the fighter who applied the submission is declared the winner. The losing fighter made an active choice to concede defeat.

In professional MMA under the Unified Rules, the referee must see or hear the tap to stop the fight. If the fighter taps but the referee doesn't notice, the fight continues until the referee recognizes the tap, the fighter loses consciousness, or the fighter escapes the hold. This has led to controversial finishes where fighters claim they tapped but the referee didn't see it.

Technical Submission (Referee Stoppage)

A technical submission occurs when the referee stops the fight because the fighter has been rendered unconscious while trapped in a submission hold. In this scenario, the fighter cannot tap because they are unconscious. The referee intervenes to prevent further injury. The result is still recorded as a submission victory for the fighter who applied the hold.

Technical submissions are a safety mechanism. If a fighter passes out from a choke and the attacker doesn't release the hold immediately, the unconscious fighter could suffer brain damage or worse. The referee's job is to stop the fight the moment the fighter loses consciousness to prevent this outcome.

Key difference: A regular submission is voluntary (fighter taps), while a technical submission is involuntary (referee stops fight due to unconsciousness).

What Is the History and Evolution of Submissions in MMA?

Origins in Combat Sports

Submissions are not a modern invention—they have roots in multiple martial arts traditions spanning centuries. Brazilian Jiu-Jitsu (BJJ), which emerged in Brazil in the early 1900s, is built entirely around submission grappling. BJJ practitioners brought Japanese judo techniques to Brazil and evolved them into a comprehensive system of joint locks and chokes. Before BJJ, catch wrestling and Greco-Roman wrestling in Europe and North America also featured submission techniques, though they were less systematized than modern BJJ.

The submission-heavy nature of these grappling arts made them devastatingly effective when mixed martial arts emerged in the 1990s. Fighters with no grappling background had no defense against submissions, leading to a dramatic shift in how MMA fighters trained and competed.

Submissions in Early MMA

The early UFC events (1993-1995) were dominated by submissions, primarily because most fighters came from striking backgrounds and had no submission defense. Royce Gracie, a Brazilian Jiu-Jitsu black belt, famously won the first three UFC tournaments by submitting all his opponents, often fighters who were larger and stronger. Gracie's dominance proved that technical proficiency in grappling could overcome raw power and size—a lesson that transformed MMA forever.

In these early years, submissions accounted for a significant percentage of fight finishes. Fighters who knew how to submit opponents had an overwhelming advantage. As MMA evolved and fighters began cross-training in all disciplines, submission defense improved dramatically. Fighters learned how to escape submission holds, recognize danger, and defend against takedowns before they could be submitted.

Modern Submission Trends

Today, submissions remain a critical part of MMA, but they are no longer the dominant finish method. Modern fighters are well-rounded, with competent submission defense. However, certain fighters—those with strong wrestling or BJJ backgrounds—still specialize in submissions and achieve high submission rates.

Submission frequency varies by weight class and fighting style. Lighter weight classes tend to have higher submission rates because weight class restrictions mean smaller fighters cannot rely purely on strength and must develop technical grappling skills. Heavyweight fighters, who can often overcome opponents through strength and striking, have lower submission rates.

The evolution of submission techniques has also continued. Modern submissions like the D'Arce choke and heel hook variations have become more prominent in recent years as fighters discover new applications and combinations. The sport continues to evolve, with new techniques emerging and older techniques being refined.

What Are the Most Common Submissions in Professional MMA?

The Rear-Naked Choke

The rear-naked choke (RNC) is the most common and highest-percentage submission in MMA. It's applied from behind the opponent, with the attacker wrapping one arm around the opponent's neck and using the other hand to secure the grip. The RNC compresses both carotid arteries, causing unconsciousness within 5-10 seconds if not released.

The RNC is so effective because it's difficult to defend once the attacker has back control. The opponent cannot see the attacker, making it hard to anticipate the choke. Additionally, the back control position itself is dominant—the attacker can control the opponent's movement, making escape nearly impossible. Fighters with strong wrestling or judo backgrounds often achieve back control and finish opponents with the RNC.

The Armbar

The armbar is one of the oldest and most fundamental submissions in grappling. It's applied by trapping the opponent's arm between the attacker's legs and hyperextending the elbow joint. The armbar is particularly effective in MMA because it can be set up from multiple positions—guard, mount, side control—and it's one of the fastest submissions to execute.

The armbar is often the first submission taught to beginners in BJJ and MMA because it's relatively simple to understand and execute. However, it remains highly effective at the professional level because it's difficult to defend once the attacker has the arm trapped.

Other High-Percentage Submissions

Beyond the RNC and armbar, several other submissions appear frequently in professional MMA:

• Triangle Choke — Particularly effective from the guard, where the fighter on bottom can use their legs to create leverage. The triangle is a favorite of fighters with strong leg strength and flexibility.
• Guillotine Choke — Often caught when the opponent shoots a takedown and bends forward. The guillotine can be applied quickly and is difficult to escape once locked in.
• D'Arce Choke — A head-and-arm choke that has become increasingly popular in recent years. It's particularly effective when the opponent attempts an underhook, a common defensive technique.
• Kimura — A shoulder lock that's effective in top positions (mount, side control). The kimura is slower to finish than chokes but can be devastating when locked in.

What Are Common Misconceptions About Submissions?

"You Always Have to Tap"

Misconception: Fighters are obligated to tap when caught in a submission.

Reality: Tapping is entirely voluntary. A fighter can choose to refuse to tap and instead wait for the referee to stop the fight or try to escape the submission. However, refusing to tap is dangerous and can result in serious injury. Some fighters refuse to tap out of pride, but this is increasingly rare in professional MMA as fighters understand the long-term consequences of injury.

In the UFC and other major promotions, referees are trained to stop fights immediately when they see a fighter in danger of serious injury, so refusing to tap doesn't necessarily mean the fighter will be injured—but it's still a risky choice.

"Submissions Are Rare in MMA"

Misconception: Submissions are uncommon finishes in modern MMA.

Reality: Submissions account for approximately 30-35% of all UFC finishes, making them the second-most common finish method after knockouts/TKOs (which account for 50-55%). Submissions are far from rare—they're a significant part of the sport.

However, submission rates vary considerably by weight class. Lighter weight classes have higher submission rates because smaller fighters rely more heavily on technique and leverage. Heavyweight fighters have lower submission rates because they can often overcome opponents through strength and striking power.

"You Can Only Tap with Your Hands"

Misconception: Tapping must be done with the hands.

Reality: While hand taps are the standard and most common form of submission, fighters can also tap with their feet. In situations where both arms are trapped (such as in a rear-naked choke or certain arm-triangle positions), a fighter can tap the mat or the opponent's body with their foot to signal submission.

Verbal submissions are also valid. A fighter can verbally tell the referee or opponent "I tap" or "I submit," and the fight must be stopped. However, verbal submissions are less common because fighters being choked may not be able to speak clearly.

How Do Submissions Apply to MMA Betting?

For MMA bettors, understanding submissions is crucial because they create unique betting opportunities that differ from knockout or decision betting.

Submission Betting Markets

Most sportsbooks offer several submission-related betting markets:

• Method of Victory — Betting on whether the fight will end by submission (rather than KO/TKO or decision)
• Submission Props — Betting on which specific fighter will win by submission
• Round Betting — Betting on which round a submission will occur
• Parlay Bets — Combining multiple submission bets for higher payouts

Submission odds are typically higher than knockout odds because submissions are less predictable. A fighter might be favored to win, but the odds of them winning by submission specifically are longer because it depends on the opponent tapping rather than being knocked out.

Identifying Submission Specialists

The best way to find value in submission betting is to identify fighters who specialize in submissions. These fighters typically have:

• Brazilian Jiu-Jitsu backgrounds — Fighters with BJJ black belts or high-level BJJ experience are much more likely to finish opponents by submission
• Wrestling backgrounds — Wrestlers often develop strong top control and can set up submissions from dominant positions
• High submission rates — Look at a fighter's record and identify those with high submission finish rates (30%+ of their wins by submission)
• Submission-specific training — Some fighters are known for emphasizing submission training in their camps

Submission Odds and Value

Submission odds vary based on several factors:

• Fighter's submission rate — A fighter with a 40% submission finish rate should have better submission odds than a striker with a 10% submission rate
• Opponent's submission defense — If the opponent has strong submission defense or a grappling background, submission odds will be longer
• Fighting style matchup — If a submission specialist faces a striker with weak grappling, submission odds will be shorter
• Recent form — If a fighter has recently finished opponents by submission, their submission odds may shorten

Value in submission betting often comes from backing submission specialists against opponents with weak grappling defense at good odds. For example, if a high-level BJJ fighter with a 35% submission rate is facing a pure striker, backing them to win by submission at +300 or higher can offer excellent value.

What Safety Considerations Surround Submissions?

Injury Risks and When to Tap

The primary purpose of tapping is to prevent injury. Different submission types carry different injury risks:

• Joint locks create immediate pain and the threat of broken bones or torn ligaments. A fighter should tap the moment they feel pressure building in a joint lock to prevent permanent damage.
• Chokes restrict blood flow or airflow, creating the threat of unconsciousness and brain damage. A fighter should tap when they feel the choke tightening to prevent losing consciousness.

Professional fighters are trained to recognize the warning signs of each submission type and tap before serious injury occurs. However, some fighters have high pain tolerance or are determined to escape, leading them to wait longer before tapping. This increases injury risk.

Medical research on submission injuries shows that:

• Armbar injuries most commonly result in elbow dislocation or triceps rupture
• Knee reaping injuries (heel hooks, kneebars) frequently cause ACL or MCL tears
• Shoulder lock injuries (kimura, americana) can result in rotator cuff tears or shoulder dislocation
• Choke-related injuries are less common but can include tracheal damage or, in extreme cases, carotid artery damage

Unconsciousness and Brain Safety

The risk of brain damage from chokes is a serious concern in combat sports. When a fighter is choked unconscious, their brain is deprived of oxygen. If the choke is not released immediately upon unconsciousness, brain damage can occur.

Research indicates:

• 5-10 seconds of unconsciousness from a choke is generally considered safe if the hold is released immediately
• 15-20+ seconds of unconsciousness carries significant risk of brain damage
• Repeated choke knockouts over a career may accumulate damage, similar to repeated head trauma from strikes

Professional MMA organizations have strict rules requiring referees to stop fights immediately when a fighter loses consciousness from a choke. Additionally, fighters are encouraged to tap before losing consciousness rather than waiting to be choked out. Some fighters refuse to tap on principle, but this is increasingly discouraged as the medical risks become better understood.

The UFC and other major promotions have implemented medical suspensions for fighters who are choked unconscious, requiring them to be cleared by a doctor before competing again. These measures are designed to protect fighter health and prevent cumulative brain damage.

FAQ

What is the most common submission in MMA?

The rear-naked choke (RNC) is the most common submission in professional MMA. It's applied from behind the opponent and compresses the carotid arteries, causing unconsciousness within 5-10 seconds. The RNC is highly effective because it's difficult to defend once the attacker has back control, and it can be applied quickly and decisively.

Can a fighter refuse to tap out?

Yes, a fighter can refuse to tap out and instead wait for the referee to stop the fight or try to escape the submission. However, refusing to tap is dangerous and increases the risk of serious injury. Professional fighters understand that tapping is a strategic choice to preserve their health for future fights, not a sign of weakness.

What happens if a fighter doesn't tap?

If a fighter doesn't tap and the referee doesn't stop the fight, the fighter will eventually lose consciousness (from a choke) or suffer structural damage (from a joint lock). The referee's job is to stop the fight when the fighter is in danger of serious injury, but there can be delays in recognition. To prevent injury, fighters should tap before reaching these dangerous points.

Is a verbal tap the same as a physical tap?

Yes, a verbal tap is just as valid as a physical tap. A fighter can verbally tell the referee or opponent "I tap" or "I submit," and the fight must be stopped immediately. However, verbal taps are less common than physical taps because fighters being choked may not be able to speak clearly.

How long does it take to become unconscious from a choke?

Most chokes cause unconsciousness within 5-15 seconds, depending on the type of choke and the fighter's physiology. Blood chokes (like the rear-naked choke) typically cause unconsciousness faster (5-10 seconds) because they directly restrict blood flow to the brain. Air chokes take longer (15-30 seconds) because they restrict airflow, which is a slower process.

What's the difference between a choke and a strangle?

In technical grappling terminology, a "choke" restricts airflow to the lungs, while a "strangle" restricts blood flow to the brain. However, in MMA and popular usage, the terms are often used interchangeably. Most submissions called "chokes" in MMA are actually strangles (blood chokes) because they compress the carotid arteries. The distinction is important for understanding the mechanics but less important for casual fans.

Can you submit with your feet?

Yes, a fighter can tap with their feet if their hands are trapped. A fighter can tap the mat or the opponent's body with their foot to signal submission. This is less common than hand taps but is a valid submission signal recognized by referees in professional MMA.

Why do some fighters refuse to tap?

Some fighters refuse to tap out of pride, toughness, or a desire to avoid the psychological impact of submission losses. However, this is increasingly rare in professional MMA as fighters and coaches understand the long-term health consequences. Modern MMA culture emphasizes that tapping is a smart, strategic choice, not a sign of weakness. Refusing to tap can result in serious injury that ends careers, making it an irrational choice from a professional standpoint.

What's the difference between a submission and a technical submission?

A regular submission occurs when the fighter taps out or verbally submits. A technical submission occurs when the referee stops the fight because the fighter has been rendered unconscious while trapped in a submission hold. Both are recorded as submission victories, but technical submissions indicate that the fighter lost consciousness rather than choosing to tap.

How do I identify submission specialists for betting?

Look for fighters with Brazilian Jiu-Jitsu or wrestling backgrounds, high submission finish rates (30%+ of their wins by submission), and recent submission victories. Analyze their upcoming opponent's grappling defense and submission vulnerability. Backing submission specialists against opponents with weak grappling at good odds often provides value in MMA betting.
