Improving Running Mechanics by Use of Interactive Sonification
Martin Eriksson, Roberto Bresin · 2010
Running technique has a large effect on running economy in terms of consumed amount of oxygen. Changing the natural running technique, though, is a difficult task. In this paper, a method based on sonification is presented, that will assist the runner in obtaining a more efficient running style. The system is based on an accelerometer sending data to a mobile phone. Thus the system is non-obtrusive and possible to use in the everyday training. Specifically, the feedback given is based on the runner’s vertical displacement of the center of mass. As this is the main source of energy expenditure during running, it is conjectured that a reduced vertical displacement should improve running economy. 1.
