Three Systems, One Gap: Combat Sports Lack a Common Data Language

At night in Incheon, I stayed behind alone in the newsroom after the weigh-in wrapped up. On my screen was a tracking sheet I had built for a mixed martial arts event: a column for age, one for weight class, one for injury history, one for the number of rapid weight cuts. Every column was empty. It was not laziness on my part. It was that almost no one records those numbers. I have never run a step in my life, yet I understand how to touch the finish line with my heart — and I also know what it feels like to stand before a fighting stage where every fact has evaporated. Combat sports are a discipline of moments measured in thousandths of a second, yet the records about the sport itself are as thin as the weigh-in sheet. I call that gap by a name: systematic obscurity. It is not the fault of one person. It is how an entire industry operates. Modern combat sports are not one block. They are three parallel systems, each with its own logic. The first is professional combat sport — MMA, boxing, kickboxing, Muay Thai — where wins and losses are decided by scorecards and how a fight ends, and all analysis revolves around head-to-head records. The second is sanda, a hybrid that allows punches, kicks and throws, sitting between traditional martial arts and professional kickboxing. The third is taolu — forms performance, scored on difficulty and performance quality, with no concept of adversarial win or loss at all. These three systems are usually lumped under a single label: martial arts. The broader the label, the thinner the data. When an analytics platform takes in the label martial arts without knowing whether it means MMA, sanda or taolu, it cannot choose the right evaluation framework. A taolu scorecard cannot be read with the round logic of MMA. A throw in sanda cannot be measured by the striking statistics of boxing. This confusion goes beyond academia; it flows straight down into money, health and athletes' careers. Based on my years of watching fights in Korea, what bothers me most is not the lack of data. It is that the data is mixed together until it becomes useless. Let us start with the most visible layer: matchups and tactics. In MMA, the first question is always stylistic balance — whether a wrestler who takes the fight down can be countered by a striker's knee. In boxing, it is the reach gap and the ability to finish early. But when the input data is empty, every matchup chain collapses. No fighter names, no weight classes, no competition rules, and no analysis stands. The second layer is athlete condition, and this is where I worry most. The age curve, weight-cut risk, wear from injury — all of it needs to be recorded. Rapid weight cutting is one of the most serious dangers in this sport, and it is nearly invisible if the promoter does not publish weight before and after stepping on the scale. The third layer is organization. Exclusive contracts tie fighters to a single promotion, making cross-promotion superfights almost impossible. Fragmented titles mean one weight class can have four champions across four different organizations. Public negotiations turn a person's career into a market stall. The fourth layer is business. Pay-per-view, ticket revenue, broadcast rights, and the revenue share for fighters. Commercial value often diverges from competitive value: a controversial fighter can sell more tickets than a quiet champion. That rule can only be read with numbers; without numbers, people are left with rumors. The fifth layer is rules and governance. The competition ruleset, drug testing, weigh-in procedure, disciplinary rulings. Each system has its own ruleset, and applying the wrong one makes every conclusion wrong. A violation in one promotion may not exist in another. The sixth layer is health and career risk: brain injury, weight-cut incidents, financial security after retirement, and mental health. In combat sports, this is the most serious risk group and it must be named, not skipped as an empty data field. The seventh layer is the public narrative. A fighter can be pushed into a phenomenon overnight, then fall when the hype cycle ends. The gap between audience expectation and actual ability is where money flows in and trust flows out. The eighth layer is the whole industry's transmission chain: from gyms and talent supply, through organizations and events, down to broadcasting, betting and consumer markets. Break one link and the signal jams at every layer below. Standing together, those eight layers show one simple thing: the combat sports industry does not lack emotion. It lacks a discipline of record-keeping. Sport is a quantified dream; I am only the one who writes that dream down in words. The crowd often thinks the problem is missing data. I think differently. The problem is that this industry refuses to admit the three systems are three systems. People try to force taolu into the win-loss mold, then are surprised they cannot read out a record. People try to compare a sanda fighter with an MMA fighter, then rush to a verdict about class. That homogenization erases distinct values. But there is a temptation more dangerous still: filling the gap with fabricated data. I have received statistic tables that looked beautiful, full of numbers, that evaporated when I checked the sources. An honest empty record still beats a dishonest full one. I do not look for the winner in the race; I look for the moment they chose not to give up — and that moment is only trustworthy when real facts stand behind it. The combat sports industry needs a common data language, but that language must distinguish the three lanes before merging them. The first step is not buying more analytics tools, but teaching the whole system to call what it is looking at by its right name. When every fighter is recorded with age, weight class, injury history and number of weigh-ins, their story finally has somewhere to stand. Otherwise, the memory of the stage will keep fading like a weigh-in sheet left to be forgotten.
