Graphs of mean forces, determined
by force plates (dotted line) and pressure insoles (solid line), and
mean absolute differences between the force plate and the pressure insole
(thicker line) for expert level (n=10) and intermediate level (n=10);
High and Low dynamic skiing modes; pitch of 15° (Flat) and 23° (Steep).
Each skiing mode includes 20 double turns × n=10 subjects. A) Expert-High-Flat, B)
Expert-High-Steep, C) Expert-Low-Flat,
D) Expert-Low-Steep, E) Intermediate-High-Flat, F) Intermediate-High-Steep, G) Intermediate-Low-Flat, H)
Intermediate-Low-Steep skiing mode. Negative (minus) absolute differences
indicate that the forces determined by the FP are greater than the PI
and positive (plus) absolute differences indicate that the forces determined
by the FP are smaller than the PI.
