The africans don't "use Pose."
Bekele, Geb, EL Guerrouj, Kipketer, etc. They all run the way that is taught by the best running form/ biomechanics coaches in the world, not the Pose method. There form has been analzyed to death by certain coaches which I have talked to and the africans are not doing the things that are recommended in the Pose method.
The only thing they have in common is the footstrike is flat on the ground basically under the center of gravity. That's it. They do not pull with the hamstring or lift their leg up or fall forward.
They push off the ground and extend their hip to go faster. Pose doesn't recommend this. Pose cuts this motion off which causes a whole slew of problems.
I've talked with biomechanics experts and to coaches who have coached world record holders on the subject of running form. All agreed with me on the above mentioned fallacies of the Pose method and pointed out that none of the top sprinters or distance runners run the way the Pose guy recommends. Some even went as far as getting out video of Carl Lewis, Wilson Kipketer, El Guerrouj, Coe, Steve Ovett, and many others and broke the video down frame by frame to show exactly what they were doing. In concluding, it wasn't pose.
So don't say the africans use Pose, they don't. Sure the foot hits the same way, but that's it. Watch the Africans leg drive and push off face, it's not cut short like in Pose. They extend their hips all the way back.
Pose guy is just trying to reinvent the wheel in a crazy way.
Please go read some biomechanics or expert running form coaches literature or hell even Newton's laws before you make such false claims.
