INTRODUCTION AND MOTIVATION
The use of new technologies in alpine skiing enables detailed analysis of technique and performance.
Key parameters such as edge angles, acceleration and timing during turns can be measured using IMU sensors, providing valuable information to evaluate skiing technique. An inertial system has been developed and validated in a ski simulator to support this analysis.
DEVELOPED PROTOTYPE
A smart ski system has been developed with all electronic components fully integrated during the manufacturing process by Kustom S.L., enabling real-time data acquisition without affecting the ski’s performance or weight.
The image illustrates the IMU placement on the ski and the measurement of key motion parameters such as roll and yaw during turns, allowing a detailed analysis of skiing dynamics.
RESULTS AND CONCLUSIONS
The first smart alpine ski prototype has been successfully manufactured and tested, reaching sampling rates of up to 200 Hz. The system enables detection of technique asymmetries and performance errors, supporting training and coaching.
Tests in indoor conditions (Madrid SnowZone) confirmed its reliability.
The graph shows the evolution of key motion parameters (yaw, pitch and roll) during skiing, enabling detailed analysis of turn dynamics and technique patterns.
Results obtained during a descent.
In 2024, we transformed the IMU, leading to a new one, more powerful and accurate:.
