Using data from a large online survey sponsored by the Michael J. Fox Foundation for Parkinson’s Research, researchers found that participants who had a history of playing organized tackle football were 61% more likely to report a Parkinson’s disease diagnosis or parkinsonism, an umbrella term for symptoms like tremors and rigidity that cause movement problems, compared with those who played other organized sports.
Yes, merely having the helmets does increase the risk of concussion. Partly because a player feels natural need to protect their head so they’re willing to take risks, and partly because a helmet converts what would have been a really bad injury into just a concussion.
Ultimately, if they are serious about reducing concussions and other injuries, they’ll ban leading with the head (already done, I think) and hits to the head (already done for “defenseless” players, not sure what that means). Hopefully next is eliminating the three-point stance to further reduce head hits. Ideally they’d also find a way to eliminate hard tackles to the ground, but I can’t think of a way to do that without banning tackles entirely.
Reduce the weight of the helmet and you’ll reduce the amount of momentum involved in the hit, drastically reducing concussions. Science!
Reduce yes, drastically probably not. You’re still going to have rapid acceleration and deceleration causing concussions.
The person wearing the helmet is still 2-300 lbs, I don’t think a reduction in helmet weight would make the slightest difference.
