I had a competition with my daughter on an easy bump run and see who ski better on this run

I think my upper body is more quiet than her.



What so you think?

Postural distortion of the head and neck can affect the vestibular system, as well as vison. This can have a negative effect on balance.

A "foward head " posture is sometimes overcompensated by an excessively lordotic lumbar region. This can affect the transference of forces from the feet.

Excessive upper body tension can cause dysfunctional breathing, which in turn can cause anxiety.

The upper body must be committed down the mountain, the rest of the body follows along. The secret for the upper body is to keep it "quiet". There's a lot of weight up there. It takes a lot of energy to move that weight around. And the muscles in the upper body don't have a lot of impact on the skis. So moving them have not muuch benefit.

However, there are some things the upper body does do -
1st, one needs to get it off the top (directly vertically above) of the skis to stay in balance when turning.
2nd, the arms can aid balance through the use of poles and timing (via the pole swing).
3rd, the stomach and back muscles can be very helpful in maintaining an upright position in response to terrain changes (eg. moguls).
4th, the head and shoulders are not always perpendicular to the skis (i.e. always looking dead ahead in the direction you are travelling). In the beginning of a turn, the shoulders should be slightly facing to the inside of the turn (pointing more downhill than the skis). After the fall line (the point in the turn when is facing directly downhill), the head and shoulders should start facing slightly oustide of the turn (still downhill). This implies that some movement of the head and shoulders, but it's very subtle and more a result of what is happening below the waist than above.
So the bottom line is let the lower body do most of the work and try to keep the upper body from doing too much.
