Is an ice skate a short, narrow ski? - Page 2

post #31 of 36

Skis and Skates are simply tools, nothing more, nothing less.  One thing these tools have in common is the ability to convert inertial (linear) travel in to centripetal (circular) travel albeit via different design points.  The skate provides a rigid curved blade while the ski provides a flexible blade which needs to be bent appropriately for the slope and varied conditions underneath. 

 

Why skaters seem to adapt to skiing faster than most is because they have experience with centripetal force and have a developed vision/sense of where the tools are taking them.

The skate is concave which means you will get critical platform angle just by standing on the skate, compared to skis where you have to edge to get it.

On the other hand the contact surface is very short so you can twist the skate out of the edge locked state without too much force, whereas for a ski this is generally not possible. On skates this twisting force can come from inside skate management, but that does not transfer well to skiing.

the skis when bent is like a loaded arch, the rebound privides the energy to cross the falline faster and start another turn faster, likewise you could use the rebound to unweight yourself like jumping up from the bottom of a trampoline. When skating you have to provide these force yourself from turn to turn. Its a lot less efficient. I guess its the major difference, otherwise the two sports is very much alike. One could easily practice similar set of skills with skating.

What happens when you subject the skate to the same fall line as the ski?

i guess the momentum will keep the skater body move forward while the skate guides the lower legs along its edge, also, because the skate runs a shorter forward displacement then the upper body,  that would naturally bend the leg as well? the difference might be there are no rebounce in skating,  in the case of skiing some skis tail got a sharp edge design, so that the rebounce is throwing the skis forward (because the skis tail is acting like a stopper) and therefore cross the fall line faster.  other skis design with smooth tails helps unweighter besides the same logic in skiating?

After this vid, you tube offered up footage of the qualifiers, which I thought were more interesting. Some of the hopefuls appeared to be good skaters who had never been on slanted ice. The guys in the final are so good it's kinda boring.
