Abstract

The studied movement is the “offset” skating technique. It is typically used by the skierfor higher-force-requirement situations: climbing up a hill, handling conditions (slowsnow or head-wind) or in low force situations. It is a thrust with the both poles for eachfull stroke-cycle of the legs. Firstly, we have made a model of a skier for a movementcycle and secondly a mechanical analysis to validate this model. This work was made thanksto the biomechanics software “LifeModeler”, plug-in of ADAMS software, which is akinematic and dynamic simulation tool. LifeModeler creates a human body as ananthropomorphic robot and ADAMS allows equipping it with tools and placing it on a ground.We have built a dynamic model in 3D for the skier in its environment, that is, with itsequipment on the snow. The final goal is to analyze performances parameters effect and tomaximize the movement effectiveness, what is possible by perfecting gesture, equipment andby optimizing materials used in this sport.
