Holy Hell, This Is How Football Helmets Are Concussion Safety-Tested

In a new study published today in the Journal of Neurosurgery, a group of scientists proved, seemingly, that modern football helmets are better than old leather ones. Thanks, guys. What is more notable, however, is that this batshit crazy device is how the data was gathered.

The tests run here, by a group of scientists associated with Virginia Tech, found that 10 modern helmets performed significantly better at reducing the force transmitted to the skull from various types of impact. The results improved concussion risk by anywhere from 45 to 96 percent, which would be more encouraging if the old helmets weren't 80 years old.

The study was undertaken, presumably, to combat the idea that helmets are totally ancillary to preventing brain injuries in football, and are only meant to protect the skull. Even though it's finally commonly accepted that chronic brain trauma is a a pervasive issue in football, how to address it still draws heated debates.

The by-now prevailing wisdom is that while better equipment will always be nice, the nature of brain trauma?momentum, not impact, crashing the brain into the inside of the skull?makes helmets secondary. On this side, though Virginia Tech claims that's not so, and helmets can prevent not just large concussions, but the smaller impacts that cause brain trauma over the years. These aren't blind claims?they use information gathered over several years that measures head acceleration and deceleration in actual games. VT has run previous studies rating all helmets currently in use, and provides the definitive and widely cited database of ratings. So there's some precedent for VT doing useful work here.

It's also enough vested interest, though, for the Journal or Neurosurgery to run an editorial ahead of publication, pointing out that this paper, while peer reviewed, is in direct contradiction to a previously published paper. And, well, both probably can't be right, so we should all maybe go back and check our long division.

Enough of that, though. Let's get back to the important part here. What the hell is that machine? A quick Google image search returns a few other images of the Bugs Bunny punishment machines (impact drop tests), but writeups mainly focus on the sensors in the helmets (important), and not the spring-loaded-boxing-glove-like lab testing equipment (hugely important).

However! We were able to find you some giffable video from a local news/college project collaboration:

And also, just for fun, here's what some other helmet testing looks like with some different equipment, this time from BRAINS Inc.:

For now, though, know that modern helmets are almost definitely safer than the crap we used 100 years ago. We think. But also and more comfortingly, that they are being tested by the same equipment that punches Elmer Fudd in the head when he comes around looking for trouble. [Smithsonian]
