Abstract des Autors

Recently, alpine skiing has come through a quick expansion. This is mainly caused by the progress in the constructions of skis. The technique of skiing is very much predetermined by the shift to the use of carving skis, which in comparison to their preceding types of skis have bigger side-cut radius. Such a shape enables skiing on edges with elimination of the skid element. Furthermore, the elimination of the skid element changes the trajectory, the speed and the reaction forces between the ski and the plate. The aim of this project is to propose, construct and test a special recording device, which records the reaction forces for analysing dynamic parameters of carving skiing. We have designed such a device that we can synchronise it with the cinematographic record to make a complex analysis of the movement. Based on measurement in laboratory we were able to define the relative measurement error of this device. It is about 3 %. Verf.-Referat
