An experiment was conducted in which a semi-professional freestyle skier was instrumented with Inertial Measurement Units (IMUs) and a position sensor. The skier performed jumps off ‘kickers’ in snow parks in four different ski resorts in Northern Italy. The gathered sensor data was utilized to calculate the EFH and GRF of every jump. The data reveals convincing evidence that a positive correlation between these two parameters exists. However, the coefficient of determination, R2, indicates only a moderate correlation. The results suggest that alternating landing strategies might have affected the measured GRF as well. This indicates that a higher correlation between EFH and GRF might exist than shown in this research. Further research should focus on how individual parameters, such as EFH and landing strategy, affect the GRF. This should develop a more comprehensive understanding of how to enhance the safety and enjoyment of freestyle ski jumps for a broader audience.
