The skeletal structure of the foot and ankle differs significantly between human sprinters and non-sprinters, according to Penn State researchers. Their findings not only help explain why some people are faster runners than others, but also may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy. According to Stephen Piazza, associate professor of kinesiology, the research is the first to use magnetic resonance imaging to...

Other than Olympic race walkers, people generally find it more comfortable to run than walk when they start moving at around 2 meters per second — about 4.5 miles per hour. North Carolina State University biomedical engineers Dr. Gregory Sawicki and Dr. Dominic Farris have discovered why: At 2 meters per second, running makes better use of an important calf muscle than walking, and therefore is a much more efficient use of the muscle´s — and the body´s — energy....

Women with PAD lose ability to walk short distances and climb stairs sooner than men 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. The study was published in the February 2011 issue of the...

When it comes to shoes, some women will go through hell for a pair of Jimmy Choos. But what effect does wearing high heels have on our bodies? Clinicians have known for a long time that if you hold a limb in a shortened position over an extended period, the muscles shorten. High-heeled shoes push our heels up, which made Marco Narici from Manchester Metropolitan University wonder whether wearing heels on a regular basis could shorten our calf muscles. According to Narici, there was some...

When 100 m sprinters launches themselves from the starting blocks, the race can be won or lost in the first few strides. Acceleration through the first few strides is the key to winning gold. So when Stephen Piazza was approached by an American football star, who sprints in his position of wide receiver, to find out how he could improve his technique and training regime, Piazza decided to focus on the athlete's ankles to try to discover what gives elite sprinters the edge over ordinary...

DEAR DR. DONOHUE: I am a reasonably fit, 61-year-old male who exercises several times a week by walking and the use of Nautilus equipment. I am 5 feet, 8 inches tall and weigh 170 pounds. I recently ruptured my Achilles tendon while jogging across a parking lot to my car in a futile attempt to stay dry during one of our frequent rain storms. How could this happen? I wasn't doing anything I haven't done many times before. I regularly use the calf machine and lift almost the full stack of...
