After I wrote my most recent response, I noticed some related threads that have provided me with some good info:
"PR on a 14' stick" ***
"shortest men elite vaulters?" ***
"Short Pole Vaulters?" ***
"This is for the LITTLE GUY"
And to top it off, altius provided the excellent response just above. Thank you!
While this thread isn't particularly current anymore, I'm still very interested in understanding the role of "great technique" as a factor in determining how high someone can potentially vault.
I would like to believe that the 6.40 model is indeed real and something to strive for. There's just no other way for me to understand how vaulters who seem to be not fast enough, not strong enough, and/or not tall enough can jump heights that one previously wouldn't think they could.
Agapit keeps us focused in another thread on the fact that
height clearance=pole grip+push-off. OK, that's a great place to start. So, let's see. Imagine we have two vaulters who are physically identical in terms of height, weight, and take-off speed. Vaulter X uses something akin to the 6.40 model, while vaulter Y can be characterized as using the 6.05 model. Does this mean that the following is most likely true?
Vaulter X probably grips higher than vaulter Y.
Vaulter X probably uses a heavier pole than vaulter Y.
Vaulter X probably has a greater push-off than vaulter Y.
Vaulter X probably vaults consistently higher than vaulter Y.
Or is this an oversimplification? The potential of agapit's manifesto here is that any vaulter Y out there can become a vaulter X with an improvement in technique. A case in point: Has anyone seen the post by matthew2,
who is stuck at 14' and needs advice?
Let's say he's vaulter Y right now, albeit using perhaps the "5.00 model". He can still get great benefit by trying to incorporate as much of the 6.40 model into his own technique, right? Circumstantial evidence points to the fact that 4.75 is within Matthew's reach. Matthew's final steps, take-off/plant, and swing can be vastly improved. This will enable him to grip higher and get on heavier poles. Hell, that's 4.55 to 4.60 right there, already a 25cm+ improvement.
Matthew's potential technical improvements would allow him not only to transfer more energy into a stiffer pole, but to finally feel (through his improved timing) what it's like to take advantage of the energy stored in the pole, thus getting propelled over 4.75 or even higher.
Not to detract anything from Matthew, but if he were a woman, there'd be a lot of interest in helping someone currently at 14' but with the tools to clear 15'6"-16'. That really interests me.
If agapit or any other coach (uh, altius comes directly to mind!

) can explain how Matthew and his coach(es) can use the 6.40 model to help Matthew realistically approach 16', then I don't see that as being any less of a challenge as helping Patrik Kristiansson clear 6.05 or higher.
