N2 - Running is one of the most popular forms of exercise. Even though regularexercise is beneficial to human health, running is also often associated with an increased risk of injury. Lack of shock absorption in running shoes has often been stated as one of the main reasons for why running-related injuries have been on the increase.

Acoustic myography (AMG), a non-invasive technique that records pressure waves from contracting muscles as well as the harmonic damping of ligaments, wasapplied to four anatomical sites on the subject’s leg, during barefoot walking,jogging, running and jumping.
