In this paper, we propose motion and flying force analysis of ski-jumping using on-body acceleration sensors. We present our first analysis results of on-body acceleration sensor data from an Olympic ski jumping champion. In this study, we collected a data set of 37 ski jumps on the world-class athlete Simon Ammann, during training, World Cup competitions, and his Olympic victories 2010. Five miniaturized tri-axial acceleration sensors were attached to the athlete, recording his body movements during the ski jumps. Sensors were attached to both legs, both arms and to the athletes chest. We describe the recorded signals, identify characteristic motion patterns, and explain biomechanically descriptive parameters extracted from this data.
