Kirk, Just as you have questioned me and mocked me about so many new concepts and Ideas I have introduced here to PVP (I read every day about PV and share my findings and this should be the purpose of this advanced section, if for anything good debate and improved understanding) such as my emphasis on the benefit of a gymnastic type Tap at the bottom of the swing or my emphasis of the extension (Which I suggested was a form of a tap at the top. So what, both are coming out arched or hollow positions which are coiled in shape and add great energy to the swing and Pole?) or my suggestion that inverting beyond vertical has benefits in that it produces a more vertical fly-away and places the vaulters COG to more fully receive the energy of the uncoiling pole or that re-extending the bottom hand both lowers the vaulters COG and adds energy to the swing. All these things you said were hogwash at first, but, later claimed to except and claim as your understanding? Were are all these pearls you claim to provide and who in fact is the swine? Here to you will find yourself sadly mistaken and acting the fool not me!
Look Physics 101 Genius, from the moment the right handed vaulter leaves the runway the pole immediately begins to lean to, bend to and then rotate to the left!
Guess what? All of this and the centripetal motion of the poles rotation has an effect on the vaulters swing path in that it causes it to leave the perpendicular line of the runway and be directed left!
This is all very evident from Lavellenie's beginning square plant tp the twisting action of Lavellenies spine and the movement of his trail leg to the right during his swing starting in frame 3:19https://www.youtube.com/watch?v=RtZH3Q19w4I
What does the wise vaulter do. The wise vaulter directs his legs to the right to compensate for this effect and make his swing path again perpendicular to the runway.
You probably did this in your swing as you swung toward your top hand without even realizing it!
There, have yet once again another pearl from the pole vaulting nobody!
Every jot and every tittle adds up to more than just a little.
