Big Bend vs. Smaller Bend
hello
and is there an opinion as to where that "max' bend should occur?
on the jump that i have been describing ... t-mack 5.90.. the maximum bend happened .49 seconds from takeoff.. approximately 7 feet from a 13-8 takeoff... approx.. 3.25/10-6 from the runway... and his back was flat to the runway.. which means his mass was passing horizontal to the ground and was ready to move up with/ahead of the pole..
make sense?

Come out of the back... Get your feet down... Plant big

I can't believe it has been over 2 years since I posted this information.
And looking back at it now I am even more convinced this information with the stuff Agapit and others are posting is the key to the next WR.
Something I have been playing with since I posted this discussion was at what pole cord length can an athlete complete a jump (takeoff and swing to inversion) and rotate a straight pole into the pits safely. This is without reducing hand holds to swing easier on a straight pole. This was using the same grip spacing that the vaulter uses to vault.
A common pole cord length that was repeated by DJ desired was reducing the pole cord to roughly 11'9 to 12'1" by Bubka and others which was roughly 28 to 32% of initial pole cord length. So the question in my mind was is this the ideal pole cord to shorten too or can it be higher and still safely rotate into the pits.
Well I can safely say I have witnessed a 13'+ pole cord on a pole with a normal pole vault grip complete an entire vault to inversion and rotate the pole safely into the pit. Now would this mean this vaulter needs to only shorten his pole cord to 13' and still safely rotate the pole into the pits.
I would say yes. So would this mean he can get on a longer pole and bend it like crazy down to 13'.
I would say no because the reason he could rotate the 13'+ pole cord was because of the technique he was using during his takeoff and swing to inversion and body position in relationship to the pole cord. By performing actions that will make and produce more bend in the pole it will take away from the power of the swing to inversion and thus weaken the ability to rotate the pole cord into the pit.
As you see I feel they are all connected and just like in running if you over compensate in one area (more bend) you reduce the other (swing speed). And thus produce a lower height in return.
