I read this article last week. Everyone knows that football is a violent sport, but I never knew the extent it could have on the human brain. No surprise that the NFL was less than cooperative.
Here are the paragraphs that really stuck with me…
“Look, there was a seminal study published by the University of Oklahoma two years ago. They put accelerometers, which measure acceleration, in the helmets of University of Oklahoma players. And they documented the g-force. So we know the g-force for a football player being knocked out is about sixty to ninety g’s. To compare, a fighter pilot will pass out at five or six g’s, but that’s over a long period of time. These football g-forces are just a few milliseconds, very brief—boom! And they found that in the open field, the dramatic cases of a receiver getting blindsided is about one hundred g’s. It knocks them out. Very dramatic, everybody sees it. But the linemen? They were actually getting twenty to thirty g’s on every play. Because they start out and they bang heads. Every play.
“Helmets are not the answer. The brain has a certain amount of play inside the skull. It’s buoyed up in the cerebral spinal fluid. It sits in this fluid, floats. When the head suddenly stops, the brain continues, reverberates back. So when I hit, boom, my skull stops, but my brain continues forward for about a centimeter. Boom, boom, it reverberates back. So you could have padding that’s a foot thick. It’s not going to change the acceleration/deceleration phenomenon. And a lot of these injuries are rotational. The fibers get torn with rotation. You’ve got a face mask that’s like a fulcrum sitting out here: You get hit, your head swings around. That’s when a lot of these fibers are sheared—by rotation. A helmet can’t ever prevent that. …”
