1 Highlighted Skills PSIA-RM Development Pathway - Alpine Skiing Standards Fundamental Mechanics relative to the Skills Concept Pressure Control Rotational Control Edge Control Fore/Aft : Control the relationship of the Center of Mass to the base of to direct pressure along the length of the skis. Ski to Ski: Control pressure from ski to ski and direct pressure toward the. Overall Magnitude: Regulate the magnitude of pressure created through ski/snow interaction. Control the skis rotation (turning, pivoting, steering) with leg rotation, separate from the upper body. Control the angle of the ski to the snow through a combination of inclination and angulation.
