Running seems like a safe sport, so many people are surprised to learn that it causes frequent injuries to muscles, tendons, bones and joints. During running, your foot strikes the ground with a force equal to three times body weight, a force more than double that of walking. To convince yourself, place your hands on the huge quad muscles in the front of your upper leg while you run. Each time your leg strikes the ground, you feel the muscle shake like jelly.
A study from the University of Wisconsin-La Crosse shows that as people start to feel tired during running, they shorten their strides to decrease the force of their foot striking the ground. This lessens the force of their heel striking the ground and places it forward to the area behind the big toe. To compensate for the decreased force of their feet hitting the ground, they move their legs at a faster cadence. You should use this information to prevent injuries when you run. You can help to protect yourself from injury by shortening your stride, which shifts your foot s force forward. You can keep your speed by moving your legs at a faster cadence.
