Small calf muscles may be a feminine trait, but for women with peripheral artery disease (PAD) they're a major disadvantage. Researchers at Northwestern Medicine point to the smaller calf muscles of women as a gender difference that may cause women with PAD to experience problems walking and climbing stairs sooner and faster than men with the disease. http://phys.org/news216061992.html Medicine & Health Fri, 04 Feb 2011 17:13:36 EST news216061992 Why does it hurt walking flat-footed after wearing high heels? Marco Narici and his team from Manchester Metropolitan University looked at the calf muscles of habitual high heel wearers and found that the women's muscle fibers were shorter and their Achilles' tendons much thicker, so their tendons are stiffer and harder to stretch, which makes walking flat-footed uncomfortable after wearing high heels. http://phys.org/news198404020.html Medicine & Health Thu, 15 Jul 2010 19:00:01 EST news198404020 What is it about elite sprinters that gives them the edge over non-sprinters in the 100m dash? Stephen Piazza from the Pennsylvania State University publishes his discovery, in The Journal of Experimental Biology, that the length of an elite sprinter's heel (the distance from the back of the heel to the ankle) is 25 percent shorter in elite athletes than non-sprinters, allowing them to generate more force when sprinting for gold. http://phys.org/news176098750.html Biology Fri, 30 Oct 2009 05:21:36 EST news176098750
