hip shrug

Hi,

A question to all you technique buffs and coaches out there. How does
somebody get rid of, for lack of better terms, a hip shrug when they are
bringing up their trailing leg that they've just pushed of with during the
V-2? In other words, even though the person stands up onto the new gliding
ski, and is not skiing in the back seat, the upcoming leg's hip rises just
slightly as the leg comes under the body.

Or maybe this isn't a big deal. I see some guys do in on the World Cup
circuit as well. Seems like it's usually the taller skinnier guys from
smaller countries, but that just might be my bias. Should the trailing leg
be bent more, or earlier, during recovery? Should the gliding leg of the
V-2 be even straighter to allow the straighter trailing leg to come in with
more even/level hips?

Any thoughts are appreciated.

Brian

170, huh... Funny, I asked because to me they looked a little short,
such that even with you compressing strongly (?) at the moment of the
photo, your hand seems low (not along your ear or so). Perhaps it's the
angle. I'm maybe a 1/4" taller than you in boots and noticed last
summer doing intervals on rollerskis that I had better V2 glide and
turnover with 168.5s, but felt more comfortable with 170-172.5 in the
sense you describe. Watching some snow video with the latter showed
that I couldn't get my hands through and was coming off the ski way
early to keep up. I also suspect in V1 that feeling of extra leverage
translated into staying on the poles so long that my shoulders were
twisting. Going go back to 168s immediately allowed up my hands to go
back further and extended my glide. One other thing Noel mentions is
that those with longer necks should go shorter on skate poles. I do and
had never considered it before.

Concerning classical poles, 160 seems long. Your shoulders look
relatively flat and so 157.5-158 might be close (Noel's skate
measurement less 10 cm). Mine slope considerably and a recent video
showed that at 157+ my hips were being pushed back a tad (Zach says this
is common with overly long poles for some reason). Gauging pole length
is where video and an expert eye can really help. A subjective clue can
be picked up either double poling or in faster diagonal stride. If you
sense the turnover or timing being slowed by the poles at all, usually
on the return, then it likely is. I also noticed that with poles too
long I get tired more quickly double poling.
