Why high heels are bad for You ? Posted: 29 Jan 2012 04:51 AM PST How shoes affect human gait is a controversial topic these days. The popularity of barefoot running, for instance, has grown in large part because of the belief, still unproven, that wearing modern, well-cushioned running shoes decreases foot strength and proprioception, the sense of how the body is positioned in space, and contributes to running-related injuries. Whether high heels might likewise affect the wearer's biomechanics and injury risk has received scant scientific attention, however, even though millions of women wear heels almost every day. So, in one of the first studies of its kind, the Australian scientists recruited nine young women who had worn high heels for at least 40 hours a week for a minimum of two years. The scientists also recruited 10 young women who rarely, if ever, wore heels to serve as controls. The women were in their late teens, 20s or early 30s. All of the women strode multiple times along a 26-foot-long walkway that contained a plate to gauge the forces generated as they walked. The control group covered the walkway 10 times while barefoot. The other women walked barefoot 10 times and in their chosen heels 10 times. It was obvious, as the scientists had suspected watching the woman during their coffee break, that the women habituated to high heels walked differently from those who usually wore flats, even when the heel wearers went barefoot. But the nature and extent of the differences were surprising. In results published last week in The Journal of Applied Physiology, the scientists found that heel wearers moved with shorter, more forceful strides than the control group, their feet perpetually in a flexed, toes-pointed position. This movement pattern continued even when the women kicked off their heels and walked barefoot. As a result, the fibers in their calf muscles had shortened and they put much greater mechanical strain on their calf muscles than the control group did. The obvious question raised by the findings, though, is so what? Does it fundamentally matter if a woman's calf muscle fibers shorten and she neglects her tendons while walking, especially if she loves the looks of her Louboutins? Dr. Cronin admits says "We think that the large muscle strains that occur when walking in heels may ultimately increase the likelihood of strain injuries," he says. (This risk is separate from the chances that a woman, if unfamiliar with heels, may topple sideways and twist an ankle or bruise her self-image, which is an acute injury and happened to me only the one time.) The risks extend to workouts, when heel wearers abruptly switch to sneakers or other flat shoes. "In a person who wears heels most of her working week," Dr. Cronin says, the foot and leg positioning in heels "becomes the new default position for the joints and the structures within. Any change to this default setting," he says, like pulling on Keds or Crocs, constitutes "a novel environment, which could increase injury risk." So, if you do wear heels and are at all concerned about muscle and joint strains, his advice is simple. Try, if possible, to ease back a bit on the towering footwear, he says. Wear high heels maybe "once or twice a week," he says. And if that's not practical or desirable, "try to remove the heels whenever possible, such as when you're sitting at your desk." The shoes can remain alluring, even nestled beside your feet. Adapted from an article in New York Times |
Ever heard of Ramayan Circuit in Bihar ? Posted: 28 Jan 2012 09:00 PM PST Bihar has immense Tourism Enthalpy, There are hundreds of less known sites which have significant place in our History.
