Interesting things I did not know while doing research for skate profiles.

Interesting things I did not know before I started doing research on skate profiles.

If you have good knee bend you can make anything work...(some pros don't even know what they are skating on).

Just because something feels good to you doesn't mean it is the most efficient profile in term of speed and agility.(Brock University study).

Most efficient dual profile was 9/10 and 9.5/10.5 in study.(only dual looked at. Brock University).

Dual profiles greater than 2 ie 7/10 may cause flat spot feel between the different radius in runner,  might be better to keep changes to 2 or less ie 8/10 or 8/10/12/14 etc.(just something being suggested).

I've noticed that good knee/ankle bend makes pitch less important. I realized that when I started skipping the top 2 eyelets.

Where was the data on the flat spot from?  That doesn't make sense.  Transitions betweens different radius curves isn’t rocket science, it is foundational in rail and road design.

There was a 7/13 used in the study. Least efficient

No data.  Just talk about feel, I went back to change the wording in the first post.

That study was interesting.

Is this the study?

Corrected, no more responding with the flu and 102 fever!

That is it.

No that's a study on Pitch and what effect negative neutral and forward had in performance 

Different study than the one on profiles.
