The Skills Concept Flashcards
What are the three components of the “skills concept”?
- Rotary
- Edging
- Pressure
When turning, direct pressure toward the…
Outside ski
Pressure Control
Manages forces on the skis.
Snow pushes on the skis to make them turn.
Skiers control where and how strongly the pressure is applied.
Rotational Control
How skis turn.
Controls the direction the skis are pointed.
Control the skis rotation with…
Leg rotation, separate from the upper body.
3 components of ski rotation…
- Turning
- Pivoting
- Steering
Edging Control
How skis are tipped on their edges.
Control edges by increasing and decreasing the angle of the ski on the snow.
Edging movements allow the skier to direct the skis to control (what 3 things)…
- Turn radius
- Shape
- Speed
Edging movements begin at the…
Ankles and feet and are progressive
Base of Support (BOS)
Area around feet, ski boots and bindings that connects you to the ground.
When moving the body in skiing, it is relative to..
The base of support (BOS)
Center of Mass (CM)
The mean location of mass of a body.
Five Technical Alpine Skiing Fundamentals
- Control the relationship of the Center of Mass to the Base of Support to direct pressure along the length of the skis.
- Control Pressure from ski to ski and direct pressure toward the outside ski.
- Control edge angles through a combination of inclination and angulation.
- Control the skis rotation (turning, pivoting, steering) with leg rotation separate from the upper body.
- Regulate the magnitude of pressure created through ski/snow interaction.
Components of for/aft pressure control
- Ankles
- Knees
- Hips
When directing pressure to the outside ski while turning, the the knee and hip of the inside leg flex (more/less) than the outside leg in order to direct pressure to the outside ski?
More
The knees and hip on the outside leg flex (more/less) than the inside leg to direct pressure to the outside ski?
Less
The upper body faces and tilts toward the (outside/inside) ski during turns?
Outside Ski
2 components of Rotational Control Movements
- Leg Rotation
- Upper body rotation
Leg Rotation
How legs move to control the skis’ rotation.
Most effective
Controls how long, how much, and how fast skis turn
Controls each ski separately.
Upper Body Rotation
Upper body turns first, then legs.
Not ideal: Hard to control turns, and the inside ski may turn before the outside ski, forcing the skier to make other adjustments.
Which rotation should be avoided: leg rotation or upper body rotation
Upper Body Rotation
Inclination
Simplest form of moving your center of mass to the inside of your turn
Use inclination to balance against lateral forces.
Should occur from feet to head.
Inaccurate Inclination
Leaning upper body into the turn while their feet and legs do not or they incline without sufficient angulation.
Two types of Angulation
- Knee Angulation
- Hip Angulation
