Clinch fighting permitted — fundamental to Muay Thai; Knees + elbows in clinch are legal and heavily scored; Sweeps from clinch (without slamming) are legal
Why people argue about this
People often assume that clinching in Muay Thai is strictly about holding opponents without realizing it's more about controlling them with strikes while maintaining balance. They think you're only allowed to hold briefly for a defensive advantage, but actually, it’s encouraged as long as you don’t slam or hold too aggressively and keep the fight moving with strikes.
Punches (closed fist); Kicks (legs, body, head); Knee strikes (clinch + flying)
Why people argue about this
People often assume that elbow strikes are only legal in the clinch position, which leads to arguments when they're used standing up as well. The confusion arises because the official verdict states that elbows are legal in both clinch and standing range, yet many fighters and fans believe this rule applies exclusively to the clinch scenario.
Standing 10-count for knockdowns; 3-knockdown rule per round: 3 knockdowns = TKO; KO + TKO via stoppage = total victory
Why people argue about this
People often assume that getting hit three times in a round means you're out immediately, forgetting about the knockouts aspect - which is actually if a fighter receives three knockdowns AND at least one knockout during a round, they get a technical knockout (TKO). It's this "knockout" part that gets overlooked.
3 rounds × 3 minutes (60-second rest between rounds); Championship fights: 5 rounds × 3 minutes
Why people argue about this
People often assume that all Muay Thai matches are 3 rounds of 3 minutes each, forgetting about the Championship fights which go for 5 rounds instead. This oversight leads to confusion because it's a significant difference in match duration and strategy preparation.
Foot sweeps + reaps to bring opponent down (with feet only, no judo throws); Holding+slamming explicitly prohibited
Why people argue about this
People often assume that since foot sweeps are permitted in the clinch, they can be used as a way to slam their opponent onto the canvas floor, which is technically against the rules. The confusion arises because the rule specifically prohibits holding and slamming, even if the sweep itself is allowed.
4-oz MMA-style fingerless gloves — open palm (distinct from traditional 8-10oz Thai boxing gloves); Mouthguard: mandatory; Groin protector: mandatory (men); chest protector for women
Why people argue about this
People often assume that shin guards are mandatory in Muay Thai matches, which leads to misunderstandings when they see professional bouts without them. However, the official verdict clarifies that no shin guards are used in professional Muay Thai matches with ONE Championship, unlike amateur or traditional styles where shin guards are standard for safety.
Ring: square boxing-style ring (typically 6m × 6m to 7m × 7m), 4 roped sides, padded canvas floor; Distinct from MMA cage — fighters bounce off ropes; Mandatory padded turnbuckle corners
Why people argue about this
People often assume that the size of the ring in Muay Thai matches is universally 6m x 6m, forgetting that there's a wide range from 6m × 6m to 7m × 7m specified by Section 3. They also misunderstand that the mandatory padded turnbuckle corners are a distinct feature specific to Muay Thai, not just an MMA thing.
Two competitors per match; Weight classes (Men, kg): Strawweight, Flyweight, Bantamweight, Featherweight, Lightweight, Welterweight, Middleweight, Light Heavyweight, Heavyweight (ONE-specific scaling); Women's divisions: Atomweight, Strawweight, Flyweight, Bantamweight, Featherweight
Why people argue about this
People often assume that having four officials in addition to a ringside physician is just for show, but actually, these officials are crucial for ensuring fair fights by monitoring everything from strikes to illegal holds, and they're also there to manage potential medical emergencies quickly and efficiently during the bout.
3 rounds × 3 minutes (60-second rest between rounds); Championship fights: 5 rounds × 3 minutes; Punches (closed fist)
Why people argue about this
People often assume that in Muay Thai matches, you're only allowed to use punches from the clinch position, forgetting that knees and elbows are fully legal throughout the fight. This leads to arguments about whether a move is valid or not based on where it's performed rather than what technique was used.
10-Point Must scoring (boxing-style); Judges weight: damage dealt, ring generalship, clean strikes, aggression, defense; Distinct from Thai-traditional scoring (which weights ring-walking, technique purity, dominance late in the fight); ONE's Westernized scoring favors knockout-attempting aggression
Why people argue about this
People often assume that scoring in ONE Championship's Muay Thai uses traditional Thai criteria, focusing on techniques like kicks, knees, elbows, and punches. However, they misunderstand when they see a system that emphasizes damage dealt, ring generalship, and aggression over these classic elements, leading to confusion about the fairness and relevance of such metrics in judging fights.
Illegal strikes: head-butts, back-of-head, throat, spine, eye-poke, groin → warning → point deduction → DQ; Slamming opponent from clinch: DQ; Hitting on the break: warning → point deduction
Why people argue about this
People often assume that head-butts are only penalized with a disqualification (DQ), forgetting that ONE Championship also deducts points for such illegal strikes. They mistakenly believe these infractions are treated as equally severe regardless of whether it results in a loss or just a deduction.
Muay Thai is full-contact 8-limb striking with elevated injury risk (KO, lacerations, fractures, joint trauma from kicks/elbows). ONE Championship mandates: comprehensive pre-fight medical (neurological, cardiac, ophthalmological, MRI for major bo...
Why people argue about this
People often think that ONE Championship's safety considerations mandate superfluous pre-fight medical tests for every fighter, which they see as an unnecessary burden on athletes. In reality, these tests are designed to ensure fighters' health and safety by identifying potential risks before matches, not just for the sake of having them.
