Maybe this will help:

Kinematics Measurements of Snowboarders' Ankles

FASTRAK, with four six-degree-of-freedom position sensors, was
converted into a fully portable system operating on two 12-volt batteries
and connected to laptop computer. The sensors were attached to the shanks
and feet of a snowboarder.

Hi -

I don't know much about the area myself, but your email reminded me of a
paper submitted to a conference I attended last year:

"Rotation of the Ankle Joint Complex in Snowboarding"
Delorme,S, Tavoularis,S, Lamontagne,M.

The conference was the IASTED international conference on Biomechanics 2003
in Rhodes, Greece.

The Authors were from the University of Ottowa, Canada.

The best bet is probably to contact the authors directly, as they might be
able to provide more than the abstract in the proceedings (although it is a
5 page abstract with quite a lot of detail), and presumably know more about
what work has been done in this area.

If you can't find anything else, let me know and I can send you a (dodgy!)
copy of that abstract from my copy of the proceedings.

The basis of the paper is testing whether stiffer boots would reduce
injuries.

Hope this is of some use to you.

Good luck!

I'm a post-doc in biomedical engineering at the Case Western Reserve University
in Cleveland. I'm originally from Switzerland and I'm also a snow-board
instructor. The topic of your dissertation project sounds very interesting.
I'll see if I can find some material for your research from friends back home,
but I cannot promise a lot, especially regarding basic biomechanics.
Last year I got exposed to some teaching here in Ohio and I noticed some
differences between the "American" and the "Swiss" methods. I'm planning to do
more this year and to participate to courses, so that I can figure out if it is
a "local" (i.e. "Ohioan") thing, or if the American and Swiss/European teaching
are indeed based on different body movements. I'll let you know what I find
out.
Would it be possible for me to have a copy of your project when you are done?
Thanks!

have a nice day,

Andrea

I just did a quick MedLine search on the keyword "snowboard" and found 56
entries, all but one focusing on injuries related to snowboarding. I've
attached the only title that looked at all helpful to you however it's in
German which you may have better luck getting a hold of than I. Based on my
quick search, it does not appear much has been done in the area of biomechanics
(though there has been plenty in skiing. There was an interesting one by C.F.
Ettlinger et al entitled "A Method to Help Reduce the Risk of Serious Knee
Sprains Incurred in Alpine Skiing." Perhaps some of the methods might be
useful to you despite the differences in technique.)

my name is ronald burger. i'm a assistant at the university of mainz in
germany. (one of) my (main-) research project is the method to teaching
snowboarding with the help of biomechanics. so i have wrote different papers
in german-language about this problem.
in this papers i sign the way from the psychological interest of the boarder
(flow-event) to a research with 100Hz kinematografy from turns of 5 boarders
with a high level license on the stubaital-gletscher (?).
all older studies i was finding, desrcribe the turns with hardboots on
alpinboards.
the next paper design the biomechanical methodology of learning-steps.
at the next weekend i have a keynote about a new teaching plan for skiing
and boarding.
best regards
ronald

I would start with the proceedings of the recent biomechanics conference
held at the University of California-Davis. I saw a handful of titles
(ie, the friction of snow, etc) that would give you a foundation to get
started. I'll forward the link in the event that you didn't see it last
week.

Hi

You should try looking at the conference presentations at this years
Canadian Society for biomechanics in Halifax, it was held in August. One
of the presentations had to do with snowboarding. Another place you
could try is www.health.uottawa.ca/hklab and check the masters thesis
and undergrad projects that we post there, i think one had to do with
snowboarding but i'm not sure.

good luck!

I have not come across biomechanical snowboard stuff that i can recall,
but the other day i was playing aorund with our force plate here when a
guy passsing by got interested. He thought the system could be used to
teach his kids how to stear the board (shifiting weight etc). I hade
made a system which showed the COP (center of pressure) in real time on
the wall (using a video projector). This can be used a as a feedback
system. So one idea could be to investigate the use of force plates for
some aspects of the snowboard training.

Tom Coeckelberghs
The professor who helped me with my paper has forwarded your mail to me.
My name is Tom Coeckelberghs. I work for the Belgian Snowboard
Federation. I organise events, contests and snowboarding education. I've
studied at the University of Leuven where I graduated in 1999. My
research paper was all about snowboarding for the same reasons as you. I
compared muscle activity in freestyle and slalom snowboarding for
muscles of the legs (gastrocnemius, restus femoris, vastus medialis and
lateralis, tibialis anterior and biceps femoris). I compared rear leg
with front leg, frontside and backside turn, in slalom (hard boots and
narrow board) and freestyle (soft boots with flexible and large board).
I used one particular technique for both snowboard styles (In English I
would call it "stretch-turn"). I used EMG signals of the selected
muscles and used a little machine to measure the knee angle. Based on
those results I divided the back and frontside turns in different
phases. I think the article was not bad because I went to San Fransisco
for a congress of sports biomechanics where I had a poster session about
my paper. Of course, only the young scientists were interested in
snowboarding... but who cares, it was a free holiday.
A few of my friends who graduated the year after me did also a little
investigation about snowboarding.
If you want, I can search the articles and send them to you, either by
mail or post? OK?

With kind regards,
Tom

I am also a student in the field of biomechanics and a former snowboard
instructor. I am very interested in hearing anything that people report
back to you.

This summer at the Canadian Society for Biomechanics there was a
presentation on simulated snowboarding landings by
Uwe Kersting, from the University of Auckland. It was interesting to
see some work on the biomechanics of snowboarding. Here is a copy of
the abstract.

David P. Dillard"
Here are some citations that may prove useful to you. A significant
portion of the literature having to do with snowboarding has to do with
injuries that is in the direction of biomechanics and snowboarding.

Please pardon duplication of citations. I tried to catch these, but
as several resources were consulted, some duplicate citations may
have slipped through.

references
worth checking out or name researchers in that field.

We have attempted to do just such a study and were not successful in
finding any previous literature. We completed some pilot work
comparing two different turns two winters ago and are going to
continute that work this winter. Please keep me posted as to how your
study progresses. We are particularly interested in your methodology.
I can send you what we have done up to this point if you are
interested.
Blessings

am not and have never been directly involved in snowboarding research.
However, I do know there is a great deal of ski research out there. With this
information, you can devise methods of taking measurements on a snowboard,
similar to those that have been accomplished through skiing. That's pretty
vague, though.

I do know you can search PubMed for such research articles and many will show
up. Just figure out the correct keywords. (Snowboarding, gait, mobility,
biomechanics, pressure distribution, etc). I know there have been a couple of
studies from Canada looking at the biomechanics and resulting plantar pressure
distribution during ski turns. They had the same goals as yours.

As a basic answer, there has been plenty of research accomplished with
snowboarding. J. of Biomechanics, American College of Sports Medicine, Eur. J.

of Physiology, Amer. J. of Physiology, Eur. J. of Sports Physiology,
International J. of Biomechanics, and many more have all published snowboarding

related articles. You can also check on the Soloman R&D, Burton R&D and other
snowboarding manufacturers websites for a name in Research and Development. E-
mail them and they should be able to send you a bibliography of published
articles they have put out over the past x-number of years, usually 5 or 6.

I hope these ideas help.

Diane,
Please tell Dominic Mckee, That I may have a friend who could help
immensely.
His name is Stephen Tamaribuchi. He is a biomechanical consultant for the
Olympic
athletes and other sports champions. He has worked with Bode Miller the
Olympic
Skier and worked with professional champion snowboarders in fine tuning their
performances.

You can find his website through my website at www.endlesslope.com

Go to my "Hot Stuff" page and look for the links to Biogrip and or e3.
You will
also se that I have his logos that are also linked to his site.

Also, I maybe working with an Orthopedic Physician regarding
proprioception sensory
regarding skiing and snowboarding. Something that is related to the
biomechanics
and kinesiology of skiing and snowboarding.

Please tell Dominic Mckee if I can get any information learned about the
biomechanics of snowbaorders. I am always interested in improving my
teaching
abilities for my students.

Dominic Mckee can also contact me directly if s/he has any questions. It
would be
good to exchange ideas.
