Amazing "Time Force" curve analysis of KB Snatch
 
I actually took this clip at the KB Worlds in Miami in Nov, 2007. Vasily Ginko is warming up with a 32kg KB backstage.

A Finnish scientist (?)/ KB enthusiast has done an analysis of his Snatch, plotting the different force as the KB goes up and down and as it rotates around the wrist/forearm.

Here is the paper which explains it.... in Finnish, so it's not much help, but I'd need help even if it was in English!

--------------------------------------------

My "take home" on this is just getting confirmation of what I experience when I snatch a KB as opposed to a DB. The forces on my grip, shoulder, arm are quite different, and the stabilization needed to control the "torque" involved in these forces is what I experience.

Interesting stuff.

Yeah, good vid Tom.

I immediately felt the same thing snatching a kb for the first time and then my calluses ripped!
