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 . . . 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: TESTING FOOTBALL HELMETS
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]
