Phase 1 – diminish edge angle
Flattening the skis initiates a new
change of direction. The COM carries
momentum into the next arc. The grip
of the skis diminishes and the mass
moves across the skis into the new
turn. As the skis flatten, they are easy
to redirect.

Phase 2 – establish platform and alignment
Without much edge or pressure, the turning of the legs continues. How much 《为啥我觉得和AP需要的早立刃啥的矛盾呢
the skis are turned depends on the desired turn shape and whether the
desire is to control, maintain, or generate speed. Maintaining momentum
and moving forward and inside the arc, the skier balances on the new edges
with natural separation and a centred stance. This anticipates the loads of
phase 3.

Phase 3 – loading and deflection
To complete the direction change, the angle
of the skis increases progressively against
the snow. A strong, stable stance is needed
to manage the external forces. The steering
continues to be led by the lower body.
Angulation increases edging and keeps most
of the weight on the outside ski. As the skis
bend and the forces build, this energy can
be used to generate speed and reaction,
dynamically linking into the next turn. |
