Boston marathon, world’ Two hours, compete most in Monday s 26.2 miles races, have from Kenya, Ethiopia, American and from all over the world five minute agitation mile best runner. When all eyes are in front runner famous US ‘ When; Depends peaceful Hall (3) and Kara Goucher (third in feminine match - in behind there assembly way is unexpectedly) a person, Zerk Roeber, steals with his unique continual style title. In Roeber’ A glance; the s foot and you can see anything all flustered is about: His isn’ t wears shoe. And many people’s ultramarathoners, the biological mechanics expert and doctor including thinks that’ The possible s best way to run. Some are, in fact causes the damage regarding the track shoes. When the entry to the Boston marathon in is in itself Roeber needs when technique has 8 minute mile stride width 26 miles to attempt the race barefoot is qualified the most runners can discover an absurd matter, even is obscene, posture. The runner is hooked in the shoe. Regarding the sufficient reason, will look like: The scope thick and is mainly made from 5 mm to 22 mm by the polymer, the track shoes are designed to support the foot mile after a mile rough asphalt and the rock terrain. They protect the frail shoe sole to be exempt from the glass and the wreckage, provides the padding, and, the shoe company requests, helps to turn on lathe too with the leg creates has the question to go through many places correctly our ankle. But for barefoot advocate for example Chris McDougall, author’s birth runs (Knopf, hits bookstore in May), Roeber is minority in Monday’ Does not drink s race shoe industry’ s Kool aid. In his book, McDougall follows Tahumara, races from 50 to 200 mile straight, does not use shoe ultrarunners the Mexican Tribe, maintains the health and does not have the injury. Science doesn’ t support shoe industry’ s requests ” The human is the birth breaks, ” McDougall tells PM, and that track shoes existence fixes our stride. The human is the barefoot nearly 2,000,000 years, but has only track shoes a little to compare, 40, when Nike founder Bill pieces together modern day track shoes’ Bowerman and the agglutination, the plastic and starts out from opposite directions folio the type iron core in his basement. The shoe loses muscular tissue’s cause runner in theirs foot, McDougall argued, and takes away in theirs stride natural cushion. The shoe and the shoe can the company be part of $ 25,000,010,000 spirit oil industries, including hundreds of thousands of can definitely barefoot? Or barefoot continual danger whether is the marathon athlete and the weekend jogger’s elephant? That’ s brews now in the continual community’s debate. The answer is decided by a part of classical chicken and the egg question: Whether we do run as a result of the track shoes, we do way, or track shoes whether to support the way which we run now?
Adopts it to study and to develop the laboratory in the stride in $ 2,000,000 new balanced track shoes an inside room in Lawrence, massive. , giant hydraulic piston pounds into one pair shallowly with attached loud foot’s statue’s MTS 858 miniature Bionix the Ii-a blue, by cushion track shoes’ heel. This pays great attention to test the machine, does by builds the earthquake simulator’s identical company, possibly is suitable for 5620 pound strength shoe 30 each second (, although new balanced researcher favors therefore gently in footwear). Under the hall, sits, in an exquisite wood floor middle glass plate concealment surveys shoe’s impact in the ground camera. The camera also captures the small silver dot reflection the light to wear by in a treadmill’s runner, tracks several hundreds in body’s spot in each stride period. Stretches across the room, the foot outline is projected conveys on the wall treadmill runner’ s footstrike in real-time. At the same time, transmission angle and strength computer recording data stream, after researcher explanation and analysis. This is high-tech biology mechanics, completely in design perfect track shoes service.
Some researchers and the runner thought that perhaps this double ideal shoe will be by the cushion and wide, with high-tech gel, plastic and even moving part better withstanding vibration. To other people, the consummation shoe looked that more elephant socks, guarantee the banket by only the thin cover to be exempt from the glass and other ground danger. Two design camps split between cleanly the difference stride which caters to: When barefoot runner’ When; the s gait favors in the foreleg in strikes, huge quantity shoe technology aiming toward heel to toe motion. From a 1980 research, cited repeatedly by the new balanced laboratory’s shoe expert, revealed how many more popular heel to the toe race was. Analyzes 753 runner’s forms, biological mechanics Researcher Benno Nigg discovered that the runner 80% (video recording in two races) has run with the heel to the toe motion; A faster runner 45% (these with five minutes, 182 miles stride widths or improvement) have run the heel to the toe step; The rest ran has called midfoot with any him to strike, the heel and the foreleg simultaneously collided the ground.
