Since this is only your second post, I assume that you are a rookie vaulter?
I will answer here, but also search the Beginner's Technique Forum for more fundamental explanations, and ask your question again there if you can't find what you're looking for.
Pole rotation means moving the pole to vertical. i.e. Rotating it from its angle at takeoff to 90 degrees (straight up).
The simplest explanation that I can give to answer your question is that the vaulter should be taking off in such a way that his forwards momentum from his run continues through his entire vault. To do this, the vaulter should jump off the runway at about an 18 degree angle. This will vary slightly depending on your particular technique.
The vaulter should not try to impede this momentum in any way. He should not apply any forwards pressure with his bottom hand, and he should not grip too high or use too heavy of a pole. His takeoff foot should also be "on
" rather than "under
" his top hand when his foot leaves the runway. Any of these errors will slow down this momentum, and the pole will fail to rotate smoothly to vertical.
Instead, he should choose a technique, pole weight, and grip that allows him to roll the pole to vertical (rotate the pole, as you say), so that he lands safely in the PLZ (Preferred Landing Zone, or "Coach's Box
") in the middle of the pit.
Those are the basics. The next step is to clear the bar.
