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 by 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/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 Championship’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 Vice President of Operations & Competition Matt Hume.
General Regulations & Policies Related To Athletes’ Weight
- Athletes must submit their current walking weight and daily training weight regularly. Athletes will input and track their daily weight online via a dedicated web portal.
- Athletes will be assigned to their weight class based on collated data and random weight checks. Athletes are not allowed to drop a weight class less than eight weeks out from an event.
- During fight week, weights are checked daily. Urine specific gravity will also be checked the day after arrival and three hours prior to the event. Athletes must be within their weight class and pass specific gravity hydration tests all week and up to three hours before the event. If an athlete falls outside the weight, or fails a test, they are disqualified from the event. Doctors may request additional testing at their discretion.
- Catchweight bouts are allowed. However, the athlete with the higher weight will not be heavier than 105% of the lighter opponent’s weight.
- ONE will conduct random weight checks on athletes at its discretion.
- Athletes may petition to change weight classes outside of the eight-week competition zone and must be within their new desired weight at that time. In addition, athletes must pass a specific gravity urine test when their weight is within the limits of the newly petitioned weight class. ONE doctors can request additional testing to determine the amount of weight drop allowed over a specific time.
- The usage of IVs for the purpose of rehydration will not be allowed.
