Bringing Martial Arts Home To Asia

Whether it is Karate, Muay Thai, Kung Fu, Judo, Kali, Shuai Jiao, Taekwondo, Sambo, Silat, or Aikido, martial arts has flourished in Asia for the last 5000 years. There is a homegrown martial art in almost every country in Asia that is revered and celebrated as a part of history and tradition. Under ONE Championship’s Global Martial Arts Rule Set For Competition, athletes compete in a full contact combat sport that allows the use of both striking and grappling techniques from a variety of martial arts disciplines. We combine the unique excitement and energy of a live bout, the raw and refined athleticism of the Olympics, the honorable tradition of martial arts, and the unmistakable adrenaline of a rock concert.

ONE Championship’s Revolutionary Hydration & Weigh-In System

ONE Championship’s weight classes are unlike any other martial arts organization in the world. ONE leads the global martial arts industry by banning weight-cutting via dehydration, choosing instead to implement a revolutionary system that ensures athletes are fully hydrated, fit, and healthy ahead of their bouts. The new program, which is the first of its kind for combat sports, is focused on athlete safety by introducing “walking-weight” competition via multiple weigh-ins and tests before and during fight week, including three hours before an event begins. An athlete’s “walking-weight” will be determined by a robust system that will track his or her weight on a regular basis throughout the period that the athlete is contracted to ONE. The revolutionary weigh-in program was established after thorough discussions and recommendations by ONE’s medical and competition team, consisting of Vice President of Medical Services Dr. Warren Wang, Chief Medical Advisor Dr. James Okamoto, Vice President Rich Franklin, and Senior Vice President of Competition Matt Hume.

How Does ONE’s Weigh-In Program Work?
  • An athlete’s daily training weight is referred to as “walking weight.” ONE will assign an athlete his or her weight class based on the athlete’s “walking weight.”
  • Bouts will be offered to an athlete strictly based on his or her “walking weight.”
  • When athletes arrive at ONE’s official hotel during Event Week, their weights will be checked. Every athlete must be within the restrictions of the contracted weight class or catchweight limit.
  • Two days prior to Event Day, all athletes will participate in their first official weigh-in and hydration test. Hydration will be checked through a urine specific gravity test, in which every athlete will submit a urine sample to a collection technician. Under the guidance of ONE’s doctor, the technician and doctor will test the sample to ensure the athlete is hydrated (with a urine specific gravity value of 1.0250 or below). If the athlete passes this test, he or she can weigh-in. The athlete’s weight must be within the restrictions of the contracted weight class or catchweight limit.
  • One day prior to Event Day, a second official weigh-in and hydration test will be conducted. Again, hydration will be checked through a urine specific gravity test. If the athlete passes the test, he or she can weigh-in. The athlete’s weight must be within the restrictions of the contracted weight class or catchweight limit.
  • On Event Day, athletes who have made weight and passed the hydration tests on both of the previous two days do not have to weigh-in. However, if an athlete has missed weight or failed a hydration test on either of the previous two days, then he or she must pass the hydration test and make weight on Event Day.
  • If an athlete fails the hydration test on Event Day, he or she is not permitted to compete. Should an athlete pass the hydration test, but weigh-in above the restrictions of the contracted weight class, then the bout may take place at a catchweight — as long as the athlete is within 105 percent of his or her opponent’s official weight, and if the opponent agrees to the bout. Additionally, a percentage of the athlete’s purse will be given to the opponent due to failure to make the contracted weight.
  • Post-bout weight may not exceed 5 percent over the weight class or catchweight limit. If an athlete were to commit this offense, he or she will be held to the rules below
    • First offense – athlete receives an official warning.
    • Second offense – athlete will be penalized 25 percent of his or her total fight purse.
    • Third offense – athlete will be penalized 50 percent of his or her purse. The athlete will also be permanently disqualified from competing in the weight class and must move up to the next higher weight class.
