Abstract

This paper presents an overview regarding the evaluation of existing biomechanical measurement methods regarding their feasibility of application in biomechanical performance diagnostics (BPD) in ski-jumping. Depending on the purpose of the BPD different biomechanical measurement systems have been developed and applied. Force plates as well as pressure insoles are used to assess the kinetics during hill jumps and dry land exercises. Using an inverse dynamics approach, ground reaction forces can be calculated during take-off (hill jumps and imitation jumps) based on the kinematic information. Inertial measurement units provide the opportunity to determine the orientation of the skis during flight. In order to select adequate measurement systems based on the purpose of the BPD advantages and disadvantages have to be considered.
