A former college quarterback has invented a football helmet with a radical new design. http://www.nytimes.com/2007/10/27/sports/football/27helmets.html?pagewanted=1&_r=1&th&emc=th 'Rather than being lined with rows of traditional foam or urethane, Ferrara's helmet features 18 black, thermoplastic shock absorbers filled with air that - not unlike his squirt bottle - can accept a wide range of forces and still moderate the sudden jarring of the head that causes concussion. Moreover, laboratory tests have shown that the disks can withstand hundreds of impacts without any notable degradation in performance, a longtime drawback of helmets' traditional foam." Disclaimer: I'm not trying to start a discussion on the merits of wearing a helmet. I know the usage of football helmets (where you might get hit several times in a couple of hours) is different than bicycle helmets (where you are most likely to go years without the helmet getting any contact). This is a newsgroup, though, and this sounded like news. -- Mike Kruger Give no quarter to the paradigm people.

In a 10 Minute Bill on October 16th he argued his case and has subsequently raised the matter again in Parliament. However, Jim Fitzpatrick, a Parliamentary Under-Secretary at the Department for Transport, said: "We have no proposals to bring forward legislation on compulsory cycle helmet wearing...A 2002 review commissioned by the DfT concluded that, overall there is evidence that bicycle helmets can be effective at reducing the incidence and severity of head, brain and upper facial injuries... However, the report also concluded that, making cycle helmet wearing compulsory may in some cases discourage some people from cycling, leading to decreased bicycle use." Fitzpatrick stressed that at the current levels of helmet use, enforcement would be a problem. Teenage boys, in particular, are eschewing helmets and forcing this group to wear helmets would make many turn away from cycling. Such a result would be a net loss to the health of the nation because the amount of lives saved by helmet compulsion would be dwarfed by the loss of life caused by sedentary lifestyles. "Our regular surveys of helmet wearing rates show that cycle helmets were worn by 28 per cent of all cyclists on major roads in built up areas in 2004; this compares to 16 per cent in 1994." said Fitzpatrick. "The corresponding figures for child cyclists are 14 per cent in 2004 compared to 18 per cent in 1994. The wearing rate for teenage boys has decreased from 16 per cent to 11 per cent. The 2006 helmet wearing rate survey will be published later this year. "While compulsion remains an option that we will review from time to time, it has been our view that, at current helmet wearing rates, making helmets compulsory would cause enforcement difficulties and without greater public acceptance could have an effect on levels of cycling." Roger Geffen, CTC's Campaigns and Policy Manager, said: "Peter Bone's wish to 'do his bit' for safer cycling is no doubt sincere, but totally misguided. He has blinded himself to the mass of data showing that helmet laws drastically reduce cycle use and that a cull of cyclists only makes things worse for those who remain. With new evidence just out showing that the obesity crisis is far worse than we had previously realised, it is clear that Bone's proposals would shorten thousands more lives than they could possibly hope to save."

I also would like to see a force/time graph comparing a conventional helmet with this design showing both acceleration and displacement. If it works as the six phases (step through them) shown on this web site, it is a great improvement. > Disclaimer: I'm not trying to start a discussion on the merits of > wearing a helmet.

I think there should be some mileage in a deformable metal mesh (like thick chicken wire) over a light skeleton, just to hold it in place. That might get round the ventilation issue, although the chin strap would still be the main source of discomfort for me.

Supposedly, the rationale was twofold: first, it was observed that runners who ran barefoot at least part of the time, ran faster. Second, it was observed that Nike (and competitors) had worked for decades to design and build ever-more-protective footware, yet runners were getting foot and leg injuries at the same rate. IOW, all the fancy, advertised, "scientific" protection didn't work. Parallels are left as an exercise for the reader. ;-) - Frank Krygowski

I'd be willing to bet that (as far as injuries sustained from running) about 60% is genetic, 30% is diet and the other 10% is actual training or lack of it. The more we learn about genetics, we will find the less decisions we can claim responsibility (or credit) for. And ultra-marathoners having their toenails removed is just damned creepy, there ain't no other way to say it. ~

The shoes worked great when they were brand-new, but after they had gone flat I was wondering why I paid $100 a pair for them. Sorbothane (soft urethane) is pretty shock-absorbent, and basically flat-proof. It /is/ a bit heavy however. ~

I neither run nor play tennis, but isn't this the same reasons that tennis balls go "dead" after a relatively short time of use -- and why they ship in pressurized containers in the first place? - Skip
