Mixed Martial Arts
Overview
Mixed Martial Arts (MMA) is a combat sport in which techniques from various martial arts such as boxing, kickboxing, judo, wrestling, and jiu-jitsu are freely used within the rules. As the UFC (Ultimate Fighting Championship) has grown into a globally successful promotion, MMA has moved beyond being merely a cross-style fighting event to become an established professional sport. Modern MMA continues to evolve by introducing unified rules, a weight class system, and doping tests in order to enhance the safety and fairness of bouts.

History and Origins
The roots of MMA can be found in ancient Greek pankration and Brazilian vale tudo, but modern MMA began with the UFC, founded in 1993. In its early days, events had a strong cross-martial-arts competition character, with fighters from various disciplines facing off to determine which martial art was the strongest. Over time, wrestling, boxing, and Brazilian jiu-jitsu proved to be effective, and the concept of "mixed martial arts," in which fighters train across multiple disciplines, became established. In the 2000s, unified rules were introduced and weight classes were subdivided, giving the sport a formal framework.
Competition Rules and Weight Classes
Matches are generally contested in five-minute rounds, with championship and main events lasting five rounds and other bouts lasting three rounds. An octagonal cage or a ring is used as the competition area, and fighters wear open-fingered gloves. Submission techniques such as chokes and joint locks are permitted, but dangerous moves such as eye gouging, groin attacks, and strikes to the spine are prohibited. Weight classes are divided into flyweight, bantamweight, featherweight, lightweight, welterweight, middleweight, light heavyweight, and heavyweight, among others. Weight cutting and hydration management play an important role in the sport.
Major Techniques and Strategies
MMA fighters are required to master both striking and grappling techniques. Striking includes punches, kicks, knees, and elbows, while grappling includes takedowns, takedown defense, positional battles, and submissions. Fights often begin with exchanges on the feet and then transition to ground fighting through takedowns. Fighters must train defense and transition skills in other areas in order to maximize their own strengths. In recent years, fighters with a boxing and wrestling base have performed well, and the boundary between striking and grappling is increasingly blurring.
Major Organizations and Competitions
The world's largest MMA organization, the UFC, is headquartered in Las Vegas, United States, and stands out for holding a large number of events every year. Bellator MMA, ONE Championship, PFL, and RIZIN are also expanding their influence in regional and global markets. Each organization has champions in each weight class, and rankings are determined by match results. The UFC provides content to fans worldwide through Fight Night, UFC Fight Pass, and pay-per-view (PPV).
Safety and Health Issues
MMA, like other combat sports, carries risks such as concussions, orbital fractures, and joint injuries. To counter these, fighters undergo regular MRI examinations, suspension periods, and weight-cutting guidelines. In 2024, strengthening doping tests and improving fighter welfare after the COVID-19 pandemic have become major agenda items. In addition, same-day weigh-ins have been introduced in some organizations to reduce dehydration problems caused by weight cutting.
Current Trends
In 2024–2025, the MMA industry is becoming increasingly globalized. The UFC has entered new markets such as Saudi Arabia and Spain and is expanding its events, while established star fighters are retiring and a new generation of champions is emerging. The growth of women's MMA has been especially notable, with women's strawweight and flyweight bouts recording high viewership. AI data analysis has also begun to be used in fight strategy, and sports science technologies such as wearable devices for injury prevention are being introduced. ONE Championship has attempted technical innovations such as the use of four-ounce gloves, though some of its rule changes differ from those of the traditional UFC. In 2025, reports also emerged that the UFC was considering the adoption of blockchain technology, including issuing resellable PPV tickets as NFTs.
In addition, martial arts organizations and associations in various countries continue to move toward recognizing MMA as an official sport, and discussions on its potential inclusion in the Olympic Games are ongoing. However, the brutality and safety concerns of MMA remain challenges to be addressed.
