It follows that measuring parameters of the ski-snow interaction would provide insights into the performance of both skiers and equipment. The interaction between the ski and snow during alpine skiing is a complex yet critical aspect of performance for both professional and recreational skiers.
The results of the current study apply only to simulated alpine skiing on a treadmill, and further work is required to prove the accuracy and precision of this system on snow. turn switch), the precision of these metrics is relatively low. IMU’s mounted on the boots are sufficient tools for accurate estimation of edge angle and radial force during both long and short style turns on a skiing simulator.Īs the estimation of edge angle and radial force are dependent on other estimated parameters (i.e. Further research is needed to improve the precision of field-relevant skiing metrics during in-field studies using simple measurement setups that can easily be implemented by recreational and expert skiers alike. The developed wearable system was accurate for the estimation of EA and F r, but was highly variable with low precision for both metrics. The performance of the wearable system was quantified by accuracy and precision. Two IMU’s mounted to the ski boots estimated EA and F r and compared to reference values measured with a 3D motion capture system. Participants completed simulated skiing trials on an indoor skiing carpet. The purpose of this study was to develop and validate a wearable method to estimate EA and F r. However, the estimation of these parameters via calibration-free wearable technologies has not been validated. In order to enrich skiing data to provide motion quality feedback, edge angle (EA) and radial force (F r) are parameters of interest.
Recent studies have developed wearable sensor systems to detect, classify and evaluate performance during alpine skiing.
