There are some, and I would be more than happy to provide you with either links to their websites or copies of them. The interesting thing is that the Johns Hopkins University study, which I think Mr. Pacetti was referencing, demonstrated that there were no more significant traumatic head injuries in the sport of mixed martial arts than there were in boxing. There are other studies that have been done that actually show a significantly lower number of traumatic head injuries.
One of the fundamental differences, of course, with mixed martial arts, is that there are multiple ways to win and multiple ways to lose; whereas in boxing it's principally one or two. The other distinguishing difference between the two sports comes in the training for the sport. This is anecdotal evidence, data that have been shared with me by people who have been brought up in the boxing community, but the notion is typically that for every round that a boxer would fight in an actual competition, be it 10 or 12, those boxers tend to spar for about 100 rounds in their training. If you're training for mixed martial arts, you will do some striking, some boxing training, but you will also train in takedown defence, grappling, and submissions in wrestling and judo or karate, whatever it happens to be. What happens in that kind of environment is that if you're only training one way and then you're only competing one way, the logic is that there will be more traumatic head injuries. The actual facts tend to bear that out.
I think somebody else was mentioning earlier about some of the traumatic head injuries that happen in horseback riding. It's interesting. I read an article just the other day about two doctors from the province of Alberta who were writing in response to the Canadian Medical Association's policy statement calling for a ban on mixed martial arts. These are two doctors who were disappointed that the Canadian Medical Association seemed to be coming from more of an emotional decision; it wasn't based on fact. With the traumas they've seen and dealt with in the hospitals, there are far more injuries from equestrian events, from hockey, from football, than they ever have seen in mixed martial arts.
I can provide you with a link to a website in the United States that tracks this. It's called the catastrophic sports injury something....
