Jason I believe u r correct in tht a vaulter should be pushing both arms inorder to push the pole to vert and Sooch is correct by pointing out tht some elite vaulter tend to let the left arm
(in the case of a righty) come in; but they have it high and over there head in order to drive their chest forward. Also we have to agree tht Sergey Bubka was the acception and not the rule. How many people can take-off 4 to 5 inchs off the ground before their pole bends and still have enough speed and momentum to carry into their vault? Not many, even Bubka himself admitted to only achieving a free take-off a hand full of times in his entire career. But getting back to the discussion, I believe that a high plant, both right and left arm, sets up the best positon for take-off. Also Essex had a point in saying tht these pro's are griping between 16 and 17ft. When they take-off their left arm (righty) has to come in inorder to allow them to penetrate/swing. BUT!!! you can look at any one of Bubka's, Stevenson, Mack's, Gibilisco, or Brad Walker's jumps and see tht as soon as they have planted and have begun their swing (UP!!) they push their left arm completly out. This is what i believe LHSVaulterJJR (Jason) was trying to point out. But by realizing tht that is what the pro's do we have to understand tht beginners are not at tht level. The pole vault should be taught in stages/levels. You know what I mean? For example, you don't teach a beginner to free-takeoff simply because they don't have the skill to perform tht at tht time. Also we have to consider tht the vaulter we are talking about is a female. Form between male and female jumpers are mostly the same but there are differences also. One of the reasons being the pole length difference, this tremendiously effects the form of a vaulter. All these things have to be taken in consideration before we can correct/insult a fellow vaulter tht is trying to help another. Lastly, i want to point out tht LHSVaulterJJR is correct in tht there are diffrent styles in the pole vault. A great comparison would be Tim Mack and toby Stevenson, or even Bubka and stevenson. Toby is the type of jumper who drive both arms up on the take-off (LHSVaulterJJR) also Toby is griping extremely close to 17ft. Bubka, i believe, griped 16' 8 when he cleared 20+ the many times he had done it. So as we can see there are different styles and it all depends on which one workd for you.

blah, i just wrote a responsed but it got deleted. So I'm gonna go over it again really quickly. I don't mean to be rude with my terse response, but it's so much of a hassle to rewrite it.
1.) AR01 is right, Bubka said he only achieved the prejump a few times. However he achieved the free takeoff in all of his jumps.
2.) Bubka gripped 5.18m, or 17 feet in pole length
3.) Bubka emphasized that it wasn't his athletic abilities that made him such a high jumper, but his technique. Bubka is not an "exception" but a excellent example of great implementation of the Petrov model.
4.) you should always teach vaulters fundamnetal technical concepts from the beginning. Why teach them something, and then ask them to adjust it later on when you can just teach them correctly the first time around. The free takeoff and no pressure with the bottom arm can easily be taught to beginners.
5.) The bottom arm, after the takeoff, does not straighten because it is pushing the pole to bend (after the swing). From the info I've gathered (and a little common sense), this occurs because the pole, after takeoff, begins to bend, which then causes the bottom arm to straighten. So it's not the bottom arm that pushes the pole to bend at this stage of the vault, but the bending pole causing the bottom arm to straighten. This can be observed on all levels of the vault, elite or amateur.
6.) Sure agree there are different styles, but so far the main example LHSvaulterjjr has used to back his claim is Tim McMichael, who himself explained that he did not lock the bottom arm or put upward pressure with the bottom arm on the pole.
Just out of curiousity, where do you (LHSVaulterJJR) get your technical ideas from? Can we have some names? What model is it?
