Abstract

The purpose of biomechanical diagnosis programs is to control the training process. Although ski jumping is a highly dynamic discipline, until now the biomechanical diagnosis is composed of dynamic jumping performances but only isometric and quasi-static eccentric strength tests. There rises the question if these non-specific strength tests are sufficient for the control and planning of training in ski jumping. The problem is to develop a diagnosis concept with a more discipline-specific character, but still analysing the general physical abilities of strength and power that ski jumpers need. To improve the specificity of the biomechanical diagnosis concept, we would like to introduce the following four aspects: 1. change of the body position while testing, according to the discipline specific squat position, 2. standardization of kinematics in consideration of anthropometry, 3. enhanced diagnosis of quasi-static eccentric muscle force, and 4. dynamic analysis of power under concentric and eccentric muscle action.
