ALBANY, N.Y. (AP) â” About one-third of professional mixed martial arts matches end in knockout or technical knockout, indicating a higher incidence of brain trauma than boxing or other martial arts, according to a new study in the American Journal of Sports Medicine. Officials from UFC, the sport’s major brand, seeking approval to stage bouts in New York have argued that mixed martial arts has evolved over 20 years with many safety regulations to protect fighters, including mandatory suspensions after concussions. “By partnering with the Cleveland Clinic, one of the world’s leading medical research institutions, on advanced studies aimed at not only preventing long-term brain injuries, but also identifying those predisposed to them, the UFC demonstrates true commitment to the safety of all professional athletes,” Epstein said. Researchers conducting the free, ongoing assessments of fighters’ brain health are examining factors like genetics, lifestyle or head trauma exposure and susceptibility to injury. New York state Sen. Joseph Griffo sponsored legislation that would legalize the sport and subject amateur mixed martial arts to state oversight that would include more stringent rules and regulations like those employed by amateur boxing.
