Creating
Turning Power Through Outrigger Use
Written
by Neil Lundberg – PSIA-I
Over
the past year there has been a significant amount of discussion about how the
mono-ski can be most effectively and efficiently turned, and what role the
outriggers play in this turning movement. This question not only applies to
mono-skiers, but to anyone using outriggers to compensate for limited turning
power in their feet and or legs. PSIA’s
Visual Cues to Effective Skiing provides a fresh approach for outrigger
usage. The Visual Cues to Effective Skiing will be used as a reference
point throughout this paper.
The
Visual Cues to Effective Skiing are a compilation of fundamental
movements that represent good skiing at any level. These basic movements are the foundation of good skiing;
regardless of what equipment a skier uses, including adaptive equipment.
In
an attempt to determine effective and efficient methods of compensating for
limited turning power in the feet and legs, Rotary
Movement Cues from the Visual Cues to Effective Skiing have proved to
be insightful. The following table illustrates several applicable effective and
ineffective Rotary Movement Cues.
|
Effective
Rotary Movement Cues |
Ineffective
Rotary Movement Cues |
|
The
skier’s legs turn underneath the upper body to help guide the skis
through a turn. |
The
shoulder and torso initiate the turning of the skis |
|
The
upper body remains quiet and stable. |
The
hips are thrown around to initiate the turn. |
|
The
ski is turned an appropriate amount to create a smooth, C-shaped arc in
the snow. |
The
skis pivot or ski throughout the turn, creating a Z-shaped turn. |
|
Any
rotary movements should be progressive, unless it is a necessary athletic
move to recover balance. |
The
skis turn too quickly, causing overturning, or the skis do not turn fast
enough, causing underturning. |
Regardless
of whether your student uses a mono-ski or other adaptive ski equipment, the Rotary
Movement Cues can be used as a visual reference to determine if your student
is effectively turning his or her ski(s).
For skiers using adaptive equipment it may be necessary to modify how
rotary forces are generated, but the end result should be consistent
with the Effective Rotary Movement Cues.
To
turn the ski effectively, rotary movements are generated in the feet and legs;
however, many skiers using adaptive equipment do not have this option due to
their disability. Two alternatives
to generate turning movements are currently in use. The most common alternative is to rotate or twist from the
lowest functional muscle group, thereby creating a turning force on the ski.
In the second method, commonly known as differential friction, the skier
uses the inside outrigger to create a friction point, thus allowing the lower
body and the ski to rotate in the direction of the turn.
Neither of these options, when relied upon as the sole source of
rotation, produces overall body movements or turning of the skis that falls in
line with the Effective Rotary Movement
Cues. However, each of these
alternative rotary sources has its appropriate place in the skill development of
skiers using adaptive equipment.
To
be more consistent with effective rotary movements it is recommended that
beginning mono-skiers initially use outrigger friction to create their first
turns. Using outrigger friction to
create beginning level turns will help the skier turn the ski under a stable
upper body. It will also help the
skier avoid ineffective rotary movements such as initiating the turn with the
shoulders or torso.
When
using outrigger friction to create beginner level turns several Ineffective
Rotary Movement Cues must be given particular attention.
It is important the use of friction not lead to; pivoting throughout the
turn, the skis turning too quickly, causing overturning, or the skis not turning
fast enough, causing underturning. These
ineffective movement patterns can be avoided by encouraging beginning
mono-skiers to be more bilateral in their outrigger usage.
Bilateral
outrigger use refers to the use of both outriggers when learning the fundamental
skills, regardless of the method of skiing. This approach is in contrast to a
unilateral outrigger approach which predominately focuses on the inside
outrigger. By focussing solely on
one outrigger, beginning skiers are often out-of-balance
in an edge-lock or railed ski position with far too much pressure on the inside
outrigger. In this position the
skier has lost effective control of the mono-ski.
To
avoid edge-lock problems, promote a more centered stance so the skier has a
flat-ski platform from which to turn. This
can be accomplished by having the skier maintain pressure on both outriggers, a
bilateral focus, when preparing to make his or her first turns.
A
bilateral outrigger focus should carry over into a skier’s first turns easily
because it has been a focus of previous skill development.
Students should have already practiced bilateral outrigger movements,
e.g., straight run exercises using both outriggers to maintain a balance stance,
braking exercises to control speed, etc. The
following statements illustrate how bilateral outrigger movements can be
emphasized when teaching a mono-skier or other students using outriggers to
facilitate turning.
First
turns are accomplished from a gliding straight run as the skier points both
outriggers in the direction of the turn.
·
Friction
is initially generated on the tail-end or brake of the outrigger.
·
Friction
is greater on the inside outrigger, thus creating a turning force.
·
Light
pressure on the outside outrigger facilitates a centered stance, but creates as
little friction as possible.
Linked
turns are accomplished as both outriggers are more actively steered in
the direction of the new turn.
·
Friction
continues to be generated predominately from the brake of the outrigger, but the
student is encouraged to explore friction generated from the edge of the
outrigger. This may require the
brake screw to be slightly shortened.
·
Friction
continues to be greater on the inside outrigger.
·
More
active steering of the outriggers implies that both outriggers move in the
direction of the turn, thus moving the shoulders toward the turn.
·
Although
both outriggers are steered in the direction of the turn, the inside shoulder,
hand, and rigger lead in the turn, reducing shoulder rotation and over steering.
·
Light
pressure on the outside rigger continues to facilitate a centered stance.
Intermediate
to advanced linked turns are accomplished with an increased focus on inside
rigger use and less reliance on friction to initiate turns.
·
Friction
is now generated from the edge of the outrigger, requiring that the brake screw
continue to be shortened or removed.
·
The
inside outrigger is actively steered in the direction of the turn.
·
The
outrigger movement is similar to a pole swing movement with a light touch.
·
Inside
outrigger friction at turn initiation is light and momentary.
·
Friction
movements are enhanced by counter motion of the upper and lower body thus
placing the skier in an appropriate anticipated/countered position.
·
Outside
outrigger pressure is present primarily during the last of the controlling
stage, orienting pressure to the outside and movement down the hill.
Short
radius and utility turns are accomplished with strong inside rigger friction.
·
Turn
the outrigger perpendicular to the ski creating friction with the entire edge of
the outrigger.
·
Use
outriggers and muscular tension to keep upper body pointed down the fall-line.
·
Exaggerate
up and down movements to weight and unweight the ski.
·
Eliminate
pressure/friction on the outside outrigger.
These
suggestions are not intended to be all-inclusive, but are examples of adaptive
movements using the Effective Rotary
Movement Cues. These examples also illustrate ways in which both bilateral
and unilateral outrigger movements will assist skiers in effectively turning the
ski(s).
In
summary: bilateral outrigger movements encourage more awareness of the outside
outrigger, which enhances a centered stance for the beginning skier.
Bilateral outrigger movements are effective rotary movements because they
encourage a stable upper body and through the use of friction allow the ski(s)
to be guided underneath the upper body.
Bilateral
outrigger movements also encourage the appropriate use of torso rotation by
creating counter motion between the upper and lower body.
Counter motion will be accomplished as the outriggers and shoulders are
steered in the direction on the turn as the lower body and ski finish the turn.
As the skier effectively learns to link turns this anticipated body
position should begin to play a more dominant role in the initiation of turns
and friction techniques should be decreased.
Bilateral
outrigger movements will also assist skiers in the accomplishment of other
effective movements contained in the Visual Cues to Effective Skiing.
·
The
shoulders, hips and hands are level as the skier comes through the turn, to keep
the body from tipping in.
·
The
inside hand, shoulder, and hip lead through the turn.
·
Both
hands are in front of the body.
When
using the outriggers bilaterally, instructors should encourage the following
movements; focus on gliding not braking movements with the outriggers, help
skiers efficiently move their center of mass in the direction of the new turn,
help skiers eliminate inefficient rotary movements at turn initiation.
Bilateral outrigger use will also enhance a good balance stance for the
beginning skier and give them skills that can be built upon as they continue to
improve.
Instructors
are encouraged to review the Visual Cues to Effective Skiing to determine
the effectiveness of movements and skills being taught, particularly those
movements which apply to generating turning forces for students using adaptive
equipment.
