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....

Anyone who has hiked down a mountain knows the soreness that comes a day or two after means the leg muscles have endured a serious workout. While the pain is real, it's not well understood how leg muscles cope with the force from such movement. Now researchers at Brown University have documented how muscles and tendons work in concert first to store and then to rid themselves of energy and heat. They found that tendons take on the role of shock absorbers at the time of impact. About a...

Longer toes and a unique ankle structure provide sprinters with the burst of acceleration that separates them from other runners, according to biomechanists. "At the start of a sprint the only way a runner can speed up is through the reaction force that results from the action of leg muscles pushing on the ground," said Stephen Piazza, associate professor of kinesiology, Penn State. "Long toes provide sprinters the advantage of maintaining maximum contact with the ground just a little bit...
