are you implying that a certain type of squat can reduce brain injuries???? thats basically what i got from this article....if your nose stops getting bloody than your brain will too once you smash it enough... or if you do a bunch if special barbell curls and exercises you'll be more prepared for 'collision sports'...when you say collision i think of serious contact and concussions....you do not seem to clarify what exactly you mean by collision. it certainly was not clear to me that you were NOT talking about concussions....it seems like this article is ill-informed and misguided. you should have had a disclaimer warning about the dangers of traumatic brain injury. in failing to do so, you published an article in an authoritative manner when you clearly are not a brain trauma authority. i would revise this immediately. it seems like you know how to prevent concussions or SIS (second impact syndrome), which is absurd, presumptuous and untrue.
