Heeled Shoes: High Heels Shorten Muscle Fibers
July 19th 2010 -
Women who constantly teeter on high heels through the world have some shorter muscle fibers in the calves. This is the result of an experiment that was now presented in the Journal of Experimental Biology.
Marco Narici of Manchester Metropolitan University had come across reports of secretaries from the 50 years that felt after the evening to drop the high heels pain in the calves. Together with his colleague Robert Csapo from the University of Vienna was Narici the phenomenon now with new technology on the ground.
Via newspaper advertisement, the researchers recruited participants 20-70 years, at least two years regularly paragraphs of five centimeters or more were. For the experiment chose Narici and Csapo from those women who reported similar symptoms as her fellow women 50 years ago. As a comparison group were women who say they predominate flat shoes to wear.
The result: The calf muscles were similar in both groups of women, although the same length. By MRI, the researchers were able to demonstrate, however, that the muscle fibers were shorter in the calf muscles in high-heel wearers on average by 13 percent than in the Flat shoes subjects. Such shortened muscle fibers would typically lead to less effectiveness when striding. But the researchers were able to establish that the body had already own is out: The Women’s heeled shoe companies have, on balance stronger hamstrings.
Exactly but make themselves felt uncomfortable with pulling and tingling, as soon as the ladies took off the high heels – the Achilles tendon was too tight and stiff, in order to stretch easily. The researchers recommend that women who want to not give up high heels, stretching exercises for the tendon.
Other problems associated with the high heels are expected, so hardly can be avoided. These include painful deformed feet, varicose veins and back pain.
