Concussion Research at Purdue: The Impact of Repeated Hits

Tracking every hit that the players took over the practices and games, we were able to tease
out that players’ brains were changing quite a bit. And concussions were actually really just
one type of neurotrauma. They put the helmet on and they think, “OK,
now I’m invincible.” But in reality, all the helmet is designed
to do is take an impact and spread it out over a larger area, so it doesn’t cause a
skull fracture. And by and large, they do that very well. How do we get rid of the energy in the collision
so that it’s not absorbed by your brain, and doing damage to your brain? Helmets don’t actually do a very good job
of that. The modern helmets are still much more like
the 1960s cars. You hit, and that solid structure doesn’t
absorb any energy, and your brain just sloshes back and forth, back and forth. What we want to do is create helmets that
have a crumple zone, that deform, that take a lot of that energy out of the hit and keep
it away from your brain, so that your brain doesn’t have to deal with all of the damage
that occurs when you absorb lots of energy. The focus needs to be on creating this new
style of helmets. And now, just within the last year or two,
we’ve proven that it’s not only technically feasible, but economically feasible as well. Our big focus is on protecting athletes – allowing
them, or ensuring that they are able to play more, play better, play safer. [Touchdown!]
