Using inertial sensors for reconstructing 3D full-body movement in sports - Possibilities and limitations on the example of alpine ski racing
(Nutzung eines Trägheitssensors zur Rekonstruktion einer dreidimensionalen Ganzkörper-Bewegung im Sport - Möglichkeiten und Grenzen am Beispiel des alpinen Skirennen)
The present study investigates if inertial sensors could be used for reconstructing 3D full body movements in sports. On the example of alpine ski racing, it was demonstrated that inertial sensors allow computing meaningful parameters related to a skier`s overall posture. While some parameters were obtained with sufficient accuracy and precision, others were not obtained reliably using inertial sensor-based systems. Main error sources were discussed and it was found that an accurate and precise functional calibration is most important for short duration measurements. In cases where it is not possible fixing inertial sensors to all relevant body segments (e.g. skis and arms) their orientations could be estimated. In this case parameter validity needs to be carefully verified, as even strongly related parameters may show different validities, as demonstrated in this study.
