I'm pretty sure that's Renaud Lavillenie jumping in Eugene Oregon yesterday.

Guess what happens to every single vaulter as they extend pressure with their bottom hand? You guessed it, their body moves further AWAY from the pole!
Is THAT what you think is happening on the pole? That the vaulters are just getting a longer radius on their swing?

: HOWEVER, Vaulters are NOT swinging this way until after the pole is at full bend, when the pole "becomes a highbar". Until then, the pole starts out bending in the direction of the faceplate of the box (towards the pit), and during the downswing it rotates to be bending towards the side of the box. During this time, it is NOT the same as a highbar!
The fact that the pole bend to the left side (for a right hander) during the down swing is not news to me or anyone else here. Regardless of this fact the result of extending the bottom hand forward has the same result as a gymnast on a high bar. The timing of the PUll is the most important aspect of the use of the arms and you make my point for me that when the Vaulter is in the upswing the pole is most like the highbar
During this time, any pressure on the bottom arm (shoulder, hand, whatever) is actually slowing down their swing. It is blocking the vaulter from swinging!
Is that why Bubka, Lavellenie and Walker extend their bottom (Pushing out) hand forward during their down swing because it slows them down? Does it slow down the Gymnast? No it does not ,just like it does not slow down the vaulter in. fact it speeds it up for many reasons I have already fully described!
Yes, it's bending the pole more than if they didn't press. BUT IT'S BLOCKING THE VAULTER FROM SWINGING! They won't invert early enough (without a tuck or a pike) if they do this. So they won't be able to shoot off the top of the pole as we

You do this by swinging from the TOP hand only, getting inverted as quickly as possible, and all the while raising your CoG a QUICK as you can.

Obviously lowering the center of mass will increase penetration, but to what end? As Roman and Branko have already pointed out, the vault is limited in time (~1.5s), and the goal is to get your body as high as possible. Any lowering of the COM just adds to the distance that it needs to be raised later in the vault. Keep the goal of the vault in mind: getting over the bar ...
