Abstract

In speed skating forces are generated by pushing in a sideward direction against an environment, which moves relative to the skater. There is a distinct difference in the coordination pattern among (elite) speed skaters. Models can help to give insight in this peculiar skating technique and ideally find an optimal motion pattern for each individual speed skater. The objectives of this study are to present a verified three dimensional inverse skater model with minimal complexity, modelling the speed skating motion on the straights. The model is driven by the changing distance between the torso and the skate , which is also the true input of the skater to generate a global motion. Additionally this input, which is indirectly also a measure of the knee extension of the skater, is a variable familiar to the speed skaters and coaches. In this extended abstract we verify this novel model for two strokes (left and right) of one skater through correlation with observed kinematics and forces. Preliminary results presented show that the model, despite the simplicity, was able to simulate the upper body movement accurately, while The forces on the skate were underestimated.
