Guided Uphill Arc

Activity Description:

Begin with the skis pointed down, or slightly out of, the fall line. As the skis begin to tip onto edge they are steered so they leave skidded tracks in the snow. The steering occurs at a progressive rate throughout the turn, tightening the radius of the arc as it develops. The skier continues to turn the skis to a stop.

Why This Activity Will Be Useful:

This activity develops the ability to blend edge and rotational control skills.

What The Skis Do:

• Both skis rotate a similar amount
• Skis the skis rotate progressively throughout the arc
• Skis tip at a similar rate and time
• Skis bend from center
• Skis leave skidded tracks
• Pivot point is center of each ski

How The Body Moves (CAUSE):

• Joints flex proportionately to keep the center of mass over the base of support fore/aft and laterally
• Turning movements comes from the legs under a stable pelvis and upper body.
• Tipping movements originate in the feet and legs
• The legs turn progressively throughout the arc and tighten the turn radius to create a “J” shaped turn, as opposed to a “C” shape.

Learning/Teaching Cues

• Static practice in boots: focus on keeping the pelvis and upper body stable while stepping or turning the feet to the left, back to front, and then the right. Repeat.
• Using an uphill arc fan progression, focus on rotating the legs to turn the skis. Think about the legs turning more than the body. Generate tension with the core muscles to stabilize the pelvis. Next, use the muscles surrounding your hips to rotate the femurs and turn the skis. A low edge angle will allow easier rotation of the skis.
• Focus to manage fore/aft pressure and keep the pivot point under each foot during practice activities.
• As ability to turn legs increases, play with moving weight/pressure aft and forward to experience what it feels like and what happens when fore/aft pressure is not effectively managed.
• Using fan plan, practice tipping both feet and ankles laterally to slowly increase edge angle.
• Maintain a functional amount of tension in both legs so they move at similar rate and time.
• If the outside ski tips to a higher edge angle, or tips faster than the inside ski, focus on moving the inside foot first and more than the outside foot. As these skills develop, blend so they have both skis make edge adjustments at a similar rate and time.
• Try lifting the edges of the skis off the snow to increase their edge angle.
