Study states that brain trauma occurs in 30 percent of MMA fights

All combat sports are inherently dangerous. Each time a man or woman steps into a cage, ring, or Octagon, they know that they are putting their lives on the line. A new study published in the American Journal of Sports Medicine estimates that brain trauma occurs in nearly 30% of MMA bouts.

The researchers at the University of Toronto used fight results from the UFC spanning 2006 to 2012 as their sample. According to, here are some of the findings from the research:

  • Average time between the KO-strike and match stoppage was 3.5 seconds, with losers sustaining an average of 2.6 additional strikes to the head.
  • For TKOs secondary to strikes, in the 30-second interval immediately preceding match stoppage, losers sustained, on average, 18.5 strikes, with 92.3% of these being strikes to the head.
  • Rates of KOs and TKOs in MMA are higher than previously reported rates in other combative and contact sports.

Along with the above information was this diagram detailing some of the research findings:



Concussion and brain trauma are big issues in other contact sports, and according to this study, the chance for a traumatic brain injury is far more common in MMA than other sports like hockey, football, and boxing.
