Where this comes from

Abstract

If running were controlled by OSHA, it probably would be banned. A runner hits the ground with a force of three to five times his or her body weight-a shock that is repeated over and over until the run ends. The type of surface can play a critical role in lessening the shock and therefore the risk of injury.
