| Alignment
Have you
ever wondered why some people continually struggle to
make changes in their skiing?
They take lessons and clinics. They train hard, but improvements
are slow and tedious. Ski instructors are great at coming
up with movement and skill based progressions that will
help them improve. However, when this is ineffective the
focus should shift to the interface between ski gear and
the body’s alignment.
We all know bodies are built differently and so is the
ski gear. Varying boot, binding and body angles affect
for/aft and side-to-side balance. How do we as instructor
recognize on hill alignment issue? Balance is the place
to start
According to the PSIA Alpine Technical
Manual, ‘A balanced position is necessary to allow
access to all other skills. The skiers joints-ankles,
knees, hips, lower back, flex and extend evenly and appropriately
together (not one more than the others.)’ To further
define skiing balance; the skier should stack their bones
over their joints to dynamically balance on the skeletal
structure of the body. With this in mind, what does it
look like when a skier is having alignment issues? Lets
look at the four common alignment adaptations.
Over flexed skiers are people who exhibit
excessive ankle, knee, hip, and torso flexion. The shoulder
and back have excessive roundness. The arm carriage is
presented as elbows out, hands in (like the skier is hunched
backed). Balance is biased to the ball of foot and tip
of the ski. Turns are j shaped with a stem of the downhill
ski. Balance is back and inside at turn connection, requiring
an athletic move to re-center the skier. The skier also
has a difficult time re-extending their legs to engage
the new turn. These skiers will connect turns using a
retraction move and use full body rotation through the
shaping phase of the turn. Excessive boot ramp angle,
forward lean and binding ramp angle are unwanted with
this skier.
Under flexed skier have little ankle
Dorsi-flexion. This skier’s primary flexion comes
from the knees and hips. The torso is erect and stiff.
The upper back/ shoulders lack desired roundness. The
arm carriage is at or behind the hips (hands in the pockets).
Balance is biased towards the heels and the tails of the
skis. Turn shape is Z shaped with a heavy finish. Balance
is back and inside at turn connection with abrupt vertical
movement to re-center the skier. A rotation and push of
the legs creates desired turn shape. Boots that are to
stiff, under ramped and bindings that have little ramp
angle are not recommended.
Over canted skiers knees flex out appearing
bow legged. Legs lack flexion. The hips and torso stack
erectly over legs. Back and shoulders lack desired roundness.
Arm carriage is out to the side (T shape to torso and
hands). Balance is biased to the outside of the foot rolling
the skis outward. The skier must abruptly un-weight and
rotate skis in, to connect turns. Turn shape is Z shaped
with chatter from the edges. Ski boots that have too much
outward angle of the lower boot and cuff are undesirable.
Under canted skiers are knock kneed (A-Frame
stance). Knees tend to flex inward and hip flexes excessively.
Torso tends to hinge at the waist. Skier presents too
much roundness to back and shoulders. Arm carriage is
back towards the hips. Balance is biased toward the inside
of the foot, rolling the skis inward. Turns are j shaped
with a stem to the downhill ski. Balance is back and inside
at turn connection, requiring an athletic move to re-center
the skier. This skier also has a difficult time re-extending
their legs to engage the new turn. These skiers use full
body rotation through the shaping phase. Ski boots that
have too much inward angle to the lower boot and cuff
are undesirable.
All four of these adaptations can adversely
affect dynamic balance. As good ski instructors it is
our job to educate ourselves, and our clients, about these
issues. To resolve these issues work with a local alignment
guru near you. Good luck and happy balanced skiing.
