Listening to music while running alters ground reaction forces: a study of acute exposure to varying speed and loudness levels in young women and men.

Purpose: Music listening while running enhances physiological and psychological features, resulting in a more enjoyable experience. The possible influence of music on ground reaction forces (GRF) during running, however, is unknown. Considering the 'distracting' role of music on runner's attention, we hypothesized that music would cover foot impacts against the ground.
