Running in standard running shoes may place more torque on the knees than wearing high heels!
Last month, we ran across an article in the Journal of the American Academy of Physical Medicine and Rehabilitation’s December issue. Researchers at the University of Virginia, led by Dr. D. Casey Kerrigan, measured the forces (“torque”) exerted when running in standard running shoes and found those forces were 54 per cent greater at the hip, 36 per cent higher at the knee and 38 per cent higher at the ankle than when running barefoot.
The large increase in torque in areas of the knee where osteoarthritis develops “was surprising, [Kerrigan] said, because it was greater than the increase in knee torque she had observed for women wearing high heels, which was only 20 percent to 26 percent.”
