Lateral alignment/canting and fitness???

post #1 of 8
Thread Starter 
Is lateral alignment all skeletal based? Or is it driven or influenced by muscle tension, muscle tightness etc? Are there exercises for correcting bowleggedness or knock knees?
I saw Jim Mates (of Seattle's Custom Boot Service) teaching some jumping exercises to a client. This exercises was to train the skier to move up and down in balanced manner. Anything like this for lateral alignment/positioning? Stretchs or othe flexibility training.

I ask this question because I have been measured for boot cants several times by different bootfitters and their numbers don't agree. I know things like a tight lower back or lose SI joint could totally throw the body mechanics out of whack, but anything else?

No Biomechanics guys among the bootfitters here?

The issue of biomechanics and boot fit is extensively discussed in the article
David MacPhail on Biomechanics and Skiing
The Foot and its Role in Skiing and the Birdcage Experiments

These articles are in premium articles in the supporter area of EpicSki and require a subscription. The complexity of this subject may be more appropriately presented as an article rather than a reply in a forum. The subject was controversial when originally presented and is something perhaps better explored in one of the open forums. This is actually an open subject in the private bootfitter's shop talk forum. Sounds like you have more than a casual interest in the subject. You may want to send me a Pm

There is no hard and fast, black and white answer to this.

BITD I worked for Lange and did a portion of the racer service work for several years. During that period, I would often be consulted by an experienced coach who would describe some problem that an athlete was having. The coach would ask me "so how do we fix his boots to eliminate this problem?" I would nod and say "well coach, you know know your athlete...how do (you) want to fix it?" He'd tell me.....I'd slap the boots on the jointer....cast the top lug.....and the next day they'd go skiing. The coach would then usually tell me "awsome!! fixed the problem"

The next day a different coach would come in, describe the same problem for a different athlete, ask for the opposite fix....and that would usually work too.

Go figure.

I recently saw an article in a golf magazineabout new putters. Someone had done a study that concluded that the golfers did better with the new putter because they were different not because they were better. The golfer tuned into the changed equipment and became better for a time. This may explain why many serious golfers have lots of old putters and ski racers have lots of old boots.

If anyone knows about this article please send me a link or refence to where I can find it I would like to read it again.

i would be looking at working on core stability and strengthening gluteus medius and piriformis, these control muscles help to stabilize the abduction / adduction of the upper leg therefore the knee position...i keep promising that i will get some photos of the exercise we use but i have been relaly busy and not had a suitable model to photograph

The "magic bullet" theory is alive and well in most sports......look at the number of different ways Shaquille O'Neal has tried to learn to free throws @ better than 35%........He's still a bricklayer.

In my experience with internal boot work I have noticed in people over time that they need less and less help the more they ski (100+ days per year). Not like eye glasses that over time the glass seems to get thicker and thicker. We all know that muscles will strengthen so it should be fairly obvious that there is an opportunity for improvement here. However the geometry of how the bones are stacked seems less likely to improve over time. So on one hand you have skeletal geometry factor that is semi constant, and the musculature that is totally dynamic and can adapt to any and all anomalies.

So to the question I personally feel that focused exercise can affect the amount of lateral issues of the foot and ankle more than the knee being bowed or knocked. As the knee is a simple hinge joint that only moves in one plane. Where as the “ankle” and hip are tri-planar and with certain exercises can influence range of motion and overall efficiency.

As Cem mentioned core exercise can influence the position of the femur so if we strengthen the core to fix the knee is the knee a symptom or the problem?
