Abstract

We discuss the dynamics of ski skating, in particular, the optimization problem: Maximize average speed for a given power. We begin with a mathematical model of ski skating. To simplify the analysis, we limit our attention to ski skating with no poles on a level plane. We also limit our attention to the physics of ski skating; we ignore most biomechanical considerations. In the early days of skating, ski instructors often said: “Take a long glide on a flat ski.” Many skiers interpreted this to mean: “Take a passive glide, then give a short hard push to the side.” As an application of our theory, we show that this advice is wrong. We show that the skier should start pushing to the side as soon as possible.
