Professional carving atlas

One skier. One camera. Study carving, slalom and giant slalom phase by phase.

Relative to the ski centreline. The hips travel inside while lumbar, chest and shoulders orient independently.

Each colour tracks a distinct body region. Angles use the shared slope frame; they are not joint limits or target angles.

Red boot: the more loaded ski. Colours show relative load transfer, not measured pressure. Twin snow tracks show the travelled path. Poles respond independently to hand steering, gravity and snow contact.

Watch the gate response

The camera stays at the gate. Inspect contact and the settling oscillation at half speed.

The teal arrow shows skier travel. SL: knockdown along travel, snow contact and damped return. GS: slight deflection on grazing contact; the panel follows both poles. Response depends on contact direction and speed. Spring and friction values are illustrative, not measured equipment data.

How to read the model

The skier travels over the snow; body angles use a ski-centred frame. COM is estimated from simplified segment mass fractions; it is not the pelvis point. It may move inside the skis during a loaded turn.

Force arrows explain direction, not measured newtons. Ski flex is a teaching deformation, not a ski–snow force solution.

Gate passage is not always the maximum edge or pressure instant. SL/GS differences describe these examples, not fixed rules for every skier and course.
