The Relationship between Equivalent Fall Height and Ground Reaction Force in Freestyle Ski Jumping

This study investigated the relationship between Equivalent Fall Height (EFH) and peak Ground Reaction Force (GRF) in freestyle ski jumping. 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...
