Why Rules Matter
MMA is often called “no holds barred.” That description is 30 years out of date.
Modern MMA has the most comprehensive rule set of any combat sport. The Unified Rules of Mixed Martial Arts — adopted by virtually every athletic commission and promotion worldwide — define what is legal, what is illegal, how fights are scored, and how fighters are protected.
Understanding the rules is essential for:
- Fighters – Know what scores, what fouls, and what wins
- Coaches – Train within the rules, strategize effectively
- Parents – Understand the safety framework for amateur competition
- Fans – Appreciate the sport’s structure and judging criteria
At Om’s Martial Arts & Fitness Studio, every competition-track student studies the rules as part of their training. You cannot win a fight you do not understand.

The “Grounded Opponent” Rule
A fighter is considered grounded when:
- Any part of the body other than the feet touches the mat (hand, knee, elbow, etc.)
- A fighter with one hand on the mat is grounded
You cannot kick or knee a grounded opponent’s head. You CAN strike the body. You CAN use ground-and-pound (punches and elbows) from a top position.
This rule is the most commonly misunderstood in MMA. At Om’s, students drill this distinction repeatedly.
Scoring (10-Point Must System)
Three judges score each round using the 10-point must system:
| Score | Meaning |
|---|---|
| 10-10 | Even round (rare) |
| 10-9 | Standard: one fighter clearly wins the round |
| 10-8 | Dominant round OR one knockdown |
| 10-7 | Two knockdowns OR extreme dominance |
Judging Criteria (In Order of Priority)
- Effective striking / grappling – Damage and impact. Clean strikes that land with force. Successful takedowns and submission attempts.
- Effective aggressiveness – Forward pressure with purpose. Moving forward and landing is aggression. Moving forward and missing is not.
- Cage / octagon control – Dictating position, pace, and the center of the cage.
What Judges Look For
| Action | Scoring Value |
|---|---|
| Clean strike that lands with force | High |
| Takedown that leads to dominant position | High |
| Submission attempt that forces a reaction | High |
| Ground-and-pound that causes damage | High |
| Takedown with no follow-up (stall) | Low |
| Guard pulling (no sweep or submission) | Low |
| Aggression without landing | Low |
| Cage control without damage | Low |

Frequently Asked Questions
Q: Are elbows legal in MMA?
A: Yes, in most jurisdictions and professional promotions. Elbows are legal in the UFC, PFL, and ONE Championship. However, 12-to-6 elbows (straight downward) are banned in some US state commissions. In amateur MMA (IMMAF), elbows are generally banned.
Q: Can you kick a grounded opponent?
A: You can kick a grounded opponent’s body, but NOT their head. Kicks and knees to the head of a grounded opponent are fouls. Punches and elbows to the head of a grounded opponent ARE legal (ground-and-pound).
Q: How long is an MMA fight?
A: Professional non-title: 3 rounds × 5 minutes (15 minutes of fighting). Professional title: 5 rounds × 5 minutes (25 minutes). Amateur: 3 rounds × 3 minutes (9 minutes).
Q: What is a “unified rules” fight?
