Flexible Football Helmet May Save Players Brains

Football is a game of simplephysics: One player has a pellet, and many other musicians who do not have the pellet want to stop him in his ways. Sometimes this interaction is happening at high speed. Speeds so fast that the parties involved banginto each other with aG army equivalent to a bowling ball being stopped on ahead from 8feet high.

Football is a beautifully violent play, which is the reason Americans simultaneously exalt and dread the boast. Its the same reasons people cheer when a cornerback builds the tackle or a linebacker pummels his opposing. Its also the reason that one out of every three musicians in the NFL willexperience some kind of intelligence traumaduring hiscareer. According to investigation into the cases from Frontline, there have been nearly 200 concussions so far this NFL season, and those are just the concussions that were officially reported.

The NFL has a very real head injury problem. And after years of outright denial, the organization was eventually begun to acknowledge its culpabilitythrough payouts, research grants around traumatic intelligence harms, and initiatives like the Head Health Challenge, which renders subsidies to firms is currently working on promotions in football-related chief health. One of those grant recipients was Vicis. Now, the Seattle company hasdesigned a new, flexible helmet called the Zero1 it believes can reduce the the possibility of a player prolonging a concussion.

Football players have always worn some kind of protective chief gear. Beforethe plastic boom of the 1950 s, helmets were made from leather and looked like aviator caps. It wasnt until the 1970 s that helmets included energy-absorbing foam to help mitigate the traumatic effects ofimpact. Buthelmet design hasnt evolved much in the pastforty years; today’s headgear is differentiated by a potent outer shell and padded interior thats meant to prevent skull fractures and intelligence hemorrhages.

Helmets was ever intended to prevent concussions, says Sam Browd, a pediatric neurosurgeon and a cofounder of Vicis. Unlike fractures, a concussion is a more nuanced hurt whose injurious side effects are still being investigated. What we do know is that it pas, generally, when an individual preserves an impact that causes the untethered intelligence to jostle and itstissue to strain. Doctors in the field like to use the word, if youve considered one concussion, youve considered one concussion, which is a clever direction of saying no one knows precisely what causes a concussion.

But researchers ought to have busy collectinginsights. They know, for example, that its possibly a force-related occurrence, and that rotational forces–a glancing punch, for example–are more likely to effect a concussion than head-on crashes. Still , no two concussions are the same, which builds it almost impossible to design a perfect solution. What are particularly trying to do is take this common sense approaching to it, Browd says. The more force reduction you can bring, the more likely you are to reduce the risk of concussion.

Artefact

Viciss helmet acquires impressions from the car industry, which has employed plastic bumpers and crumple zones as protective measures for decades. Its a very challenging engineering question, Browd says. Instead of trying to slow a car down over many hoofs or yards, were trying to slow these impacts down over 2.5 inches. The Zero1, which was designed with the help of Seattle design studio Artefact, revolves around a multilayered method that begins with a flexible outer shell made from a bendable plastic and ends with an inner shell and liner the hell is meant to provide a more customized adjust all over the head.

Beneath the outer shell are at the heart blanket, which is comprised of hundreds of flexible pillar that act like shock absorber. This blanket is the heart of the Vicis helmet, and was developed with the help of Per Reinhall, head of the University of Washingtons mechanical engineering government departments and a co-founder of Vicis. The pillar, which vary in length and thickness depending on their position in the helmet, are made from a resilient polymer that bends in any dedicated guidance when compressed.

Vicis CEO Dave Marver was pointed out that, upon impact, the editorials alter from an I shape to a C, and then snap back into residence in milliseconds.This, he claims, slackens the acceleration of army before it reaches the players foreman. Newtons second principle, he says. Force equals mass hours acceleration. The mass of a player’s not going to change, but if you can slow acceleration–the “a” in the equation–youre shortening force.

Here’s anelementary physics analogy to help you understand: The intelligence is like an egg yolk. Typical helmets will avoid the egg from cracking, but they wont inevitably halting the yolk from breaking inside the shell. The Zero1s core layer is meant to act like bubble wrapping, so when the egg( your chief) does make something hard, the majority of the force is likely to be redistributed. Other firms like Bell are tackling this same problem with a technologycalledMIPS, or multi-directional impact care method. Its version of Vicis’ core layer employs a revolving blanket within the helmet, which allows the chief to move with the impact, eventually displacing some of energy the intelligence would otherwise absorb.

Vicis says it’s experimented the helmet through remove tests( where the G-force of impact is measured by declining a sensor-laden dummy chief onto a fixed rubber anvil from differing elevations) and a more sophisticated, rotational experiment where a moving pendulum strikes the helmet from the side. The firm am of the view that, compared to other extending helmets from Riddell and Shutt, its helmet significantly reduces the force of impact by anywhere from 20 to 50 percent–a flesh “theyre saying” has been confirmed in third-party labs.

Tim Gay, a physics professorat the University of Nebraska-Lincoln and author of The Physics of Football , says the helmet’s principles work in theory, “but theres” few ways to know for certain without testing iton an actual player. Its very difficult to see ahead of time whether its to be working or not, he says. I appreciate that theyre trying to construct the game safer, but I want to see relevant data they have.

The company plans to testits helmet against Virginia Techs STAR rating, which measures a helmets they are able to absorb impact and potentialprotect against concussions. If the Zero1 performs according to Vicis internal test, Browd is hopeful it will have a major impact on safety. He admits that its impossible to prevent all concussions, but he points to neurology literature that states a five percentage reduction in forcecan translate to a40 percentage reduction in concussion danger. If numbers end up panning out, we think were going to significantly improve the safety of the boast, he says, including: I dont think were shortening all army the chief appreciates, but were shortening a substantial portion of the force that objective up being below the threshold that someone would prolong a concussion.

Right now, Vicis doesnt have any public contracts. The firm has receivedmore than $10 million in funding, with $500,000 coming from the NFL. The company’sboard is confident it wont have any misfortune selling the helmets( which at $1,500 are four- to five-times that of an average helmet) to NFL units next season. Eventually the goal is to get the cost down enough that the helmet can be adopted by younger players–a demographic with whichBrowd, a pediatric neurosurgeon, is all too familiar.

Browd also has afive year-old, who he says has taken an interest in the boast. I asked if he’d consider telling “their childrens” play.With current helmets, Im not sure, he says. I consider with the Vicis helmet, if we prolong the implementation of its improvements were hoping to achieve, I would feel comfortable telling my son participate because it throws the risk of the boast back towards the median. Like any boast, football is never going to be 100 percentage safe–but theres still plenty ofroom to make it safer.
