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.
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.
