I don't think this one should drop much further into the depths of this board... This discussion never left my thoughts for TOO long. I want to get this discussion going again!
The key in the pole vault (and most events) is energy. It always has been and it always will be. We all know that being energy efficient means leaking little energy. But what about the energy that is going in? This comes from speed and strength.
There is a ratio for any given jump that depicts how much energy is lost from the energy that is put in. For different technical models there is varying difficulty of attaining the desired ratio: 1 to 0... 1 'unit' of energy put in, 0 'units' of energy leaked. This is of course impossible, but it is the goal.
Assuming the vaulter is using the correct grip and pole, we can only increase the jump height in two ways:
1. Increase the energy that is put into the system
2. Decrease the 'energy leakage factor' (ELF) (Tell me that's not a cool acronym!

)
Now one must ask: Which is easier and/or more appropriate to do WHEN? Get stronger/faster (speed is arguably more important than other measures of strength, but I'll save that for a later post) and increase the energy input, or decrease the ELF with technical work?
I safely assume that "I wanna be a world class pole vaulter" doesn't come out of the mouth of most children... But what SHOULD a vaulter's early to mid childhood (~4-10) be like? I believe it should be filled with gymnastics of any type (but bars are the best!), all sorts of different athletic endeavors (especially ones that require anaerobic activity/lots of jumping, like martial arts, short distance swimming, and volleyball), any games that improve coordination and reaction time (including video games), and bombarded with the food pyramid. There can be some lifting, but preferrably largely limited to plyometric actions with bodyweight only. After the age of 6 or so, occasionally (1-2 times per month) doing some of the basic lifts (squats, bench, etc.) would not be a bad thing. Sit ups and sprints are ALWAYS okay!
The question now becomes when should they pick up a pole? Altius had mentioned 10 year olds should not be vaulting... Why not? Can you explain your reasoning?
But we are getting a little idealistic.
I didn't give much background on Fred (my generic vaulter brainchild)... I said he was 'decently athletic'. That doesn't cut it now... Here are some relevant stats taken in the first few days he joined the team:
Height: 5'9"
Weight: 126#
Bench Press: 105#
Squat: 165#
100m: 13.1 hand timed, no blocks, no spikes
Standing long jump: 7'1"
Pull ups (forward hands): 9
Sit ups (1 minute): 52
Standing vertical jump: 20"
In the world of high school pole vaulting there is a bad situation. It is most appropriate for Fred to be on the track, in the sand, and on the runway throughout the entire calendar year, but he does not know this (nor can he be on the runway because the pit is locked up until Spring)... He sees HIS physical stats and then checks out Tim Mack's website and looks at his 32" vertical, 10'6" standing long jump, and 173 pound snatch.
What should Fred do? What mistakes could he have already avoided and how? If you were his coach, what changes would you make to him and the program?
For Fred, is the ELF or the input the limiting factor?
Inside this question lies my training paradox which I've modified once again:
(Assume that every minute spent decreasing the ELF could also be spent increasing input, and that coaching and equipment for each is perfect.) As the vaulter decreases his ELF, the time it takes to decrease the ELF by the same amount increases. As the vaulter becomes capable of more input, the time it takes to increase input by the same amount increases. As the ELF decreases and input increases, the marginal height renderred decreases.* The potential for an increase in input is greater than the potential for decrease in ELF.**
*Even though elite vaulters are separated by inches, (unlike many high school competitions,) this point is still very relevant...
**Strength can keep growing and growing, but eventually the ELF will approach the asymptote of 0... I know that saying strength is potentially unlimited is a stretch, but what would you have me say? Remember that this is an idealized situation...
But like most things, IT DEPENDS... It's all dependent on the athlete and the situation. Fred's coaching and equipment is not 'perfect', whatever that is. Nobody's equipment or coaching is perfect, so extraneous variables enter the equation.
I will ask again: WHAT IS (should) FRED GONNA DO?
I will explain my graphs later today or tomorrow.

They are very basic ideas.
I hope we can get talking again!!!
