December 30th, 2013 nine:fifty eight pm These levels of g power reduction are unimpressive at the least when they are meant to depict the deceleration on the cranium (in contrast to brain). Deceleration is v^two/x wherever x is stopping distance. The gap with no helmet is close to zero And so the deceleration “g’s†need to be extremely substantial with no a single, and the real deceleration is restricted by the brain composition itself and probably by some velocity/kinetic Electrical power which the brain can comparatively safely soak up itself. In the event you improve x from 0 (let’s picture 0.5mm skull deflection?) to some significant range of milimeters “g power†(not really pressure in the least but acceleration) ought to go down drastically, not only an element of two (consider the math)Except the helmet is possibly considerably to rigid (hardly compresses in the least so just like a 2nd skull) or is severely (I suspect) to soft As a result entirely compressing very long before the head motion is stopped.
Helmets could be vastly enhanced like applying gel or liquid technologies which deforms and dampens drive significantly much better than solids. But you’ll hardly ever do away with each of the G’s Which’s The underside line.
March 28th, 2011 2:fifty five pm I gained’t take the helmet evangelist place, but I'll claim that researching how helmets operate at selected speeds then comparing These speeds into a skier’s “usual†speeds is incomplete and misleading. Just because I am touring 35mph doesn’t imply which i will impact at 35mph. If I am going flying headfirst into a tree, sure, but when I drop to your icy tricky floor, the effects will possible be way under 35 mph (a snowboarder is much more very likely to capture an edge and pivot their speed toward the ground, but that doesn’t usually happen to skiers).
March 28th, 2011 5:57 pm BTW all, in imagining back on my life of kinetic athletics, quite possibly the most extreme personal injury I acquired whilst mountain biking, and 1 that also influences me with Persistent discomfort, was a neck harm from staying cloths lined at sluggish speed beneath a fallen tree.
I don’t Consider so ,carrying a helmet Could possibly help you save you some personal injury while in case you don’t wear a helmet you definetley received’t get any safety IMO there is absolutely no draw back to wearing a helmet ,also I discover helmets heat comfy and an excellent destination to park my goggles …I can’t think of any downside to putting on a helmet right now in contrast to waiting till helmets are made improved
– Helmet would address again of head and achievable be much reduce about ears and temples. A complete deal with product will be readily available with diligently built jaw guard which was not at risk of catching on snow causing neck harm.
Some crashes simply just aren’t survivable, and designing anything for the worst circumstance circumstance – even if at all possible – isn’t about to aid if doing this leads to products which significantly discourage participation. This applies Primarily to biking helmets!
March 28th, 2011 eight:26 pm I put on 1, but I am with you on the level of defense they provide. I witnessed a gradual fall on website soft snow with a superb incline youthful Girl was wearing a helmet and still the result was a concussions. How about whiplash? We need far better selections.
March thirtieth, 2011 seven:13 pm Stephen, thanks for chiming in. I observed the helmet opinions over the Information post, and just figured a stand alone thread and linked put up could well be better, in the present as well as a resource for people learning the issue in the future, so listed here we go… it’s in fact been a tiny bit additional operate than I predicted (grin), but along with that my thoughts have modified in some techniques and gelled in Some others.
My helmet has saved me much more than after from falling ice/rocks, tree limbs, etcetera. Inside the mountains you undervalue the ability of the slipping rock or chunk of ice to get rid of/maim you. A slipping rock can perform lots much more than give you a laceration. They can certainly offer you a fractured cranium or perhaps a concussion.
February 14th, 2014 five:thirteen pm Very well, I bought the Poc Fornix Backcountry MIPS and skiied ten runs the other working day – no falls, but perfectly conscious of the chance – felt good to generally be out and skied effectively – flat quick situations. Watching the Olympics has me pondering…… I see these Terrible crashes and of course it’s really hard to view heads bouncing off the bottom and hurdles. Then I see determine skaters (who aren’t needed to put on helmuts!!!) tumble challenging but their heads rarely contact the ground. I viewed Donna Weinbrecht ski her gold medal mogul operate – no helmut!!! I under no circumstances hit my head in near to forty many years of skiing till I started sporting a helmut. Certainly they are going to secure you from severe personal injury when colliding with the item such as a tree, but is there some thing in the burden and measurement that leads The top to strike the ground extra all through a slide?
Liquid Pine-Sol Unique was the only real all-reason cleaner inside our assessments that didn’t go away streaks on the mirrored surface so that needs to be your go-to cleaner for the toilet. It had been also very good at removing cleaning soap scum and at cleaning up food stuff stains much more usually present in the kitchen area. Within our assessments, 3 spray cleaners ended up also Great at tackling cleaning soap scum but they all left streaks to the mirror.
Undeniably snow sporting activities helmets ought to be enhanced and there is much study ongoing as to precisely The easiest method to do that. Concussions (specially amongst football atheletes) are a incredibly hot subject today, and brought more and more seriously by the ones that give treatment to athletes.
April 8th, 2011 nine:thirteen pm Proper I discussed that on April 1, for the reason that most of the helmet demonstrations the thing is on the net certainly are a joke — this sort of misleading BS it is sort of prison. For example, sticking a melon within a helmet and dropping it, then dropping a melon without having a helmet. It seems to be interesting when the melon bursts, and oh ah ah oh oh it doesn’t burst when it’s In the helmet. Duh. I observed a type of checks not long ago in which they claimed the helmet and melon the place moving 30mph every time they strike, and they made it appear to be the helmet was Tremendous effective.
