Some words from Bubka himself will hurt a lot of Petrov's model absolute believers here I think...
Hope to be able to show this report soon.
This prompted me to open this new thread, since I think there's a big difference between a Petrov Model believer and someone (like me) that feels that the PM is better not due to blind, dogmatic faith, but due to the fact that the alternatives (including what I'm referring to as the Lavillenie Model) are either unknown, unproven, or undocumented to the extent that a beginner or intermediate (or even advanced) vaulter can base their training program and their technique on.
I don't know if Lavillenie's technique is actually called the Lavillenie Model (yet), but I'm calling it that, since there appears to be no specific model that he's following. It's his own. I'm sure he's following some ideas learned from sources other than the PM, but exactly what these are (and what elite vaulters have succeeded in following such a model) are still relatively unknown.
Off the top of my head, the main differences between the LM and the Petrov Model (as depicted by Sergei Bubka, Yelena Isinbayeva, and several others) are:
1. The PM is better documented. There are many references in the literature and on the internet re the PM, and there is a well-known book on the topic - BTB2 - "Beginner to Bubka and Isinbayeva too!" (Launder/Gormley 2007).
2. The PM is explained in more scientific terms, according to the Laws of Physics. Notice that I did not say that it is scientifically superior to the LM. It's just that there's very little documentary evidence thus far regarding the scientific merits of the LM - according to the Laws of Physics. There have been SOME attempts at explaining the LM, but to date, these attempts appear to me to be more junk science than scientifically provable explanations of the merits of the LM from a biomechanical perspective.
3. The PM is agnostic to both male and female vaulters. While the LM might well be just as applicable to females as males, but there's very little evidence that this is the case. In fact, there is some evidence that the LM might be too difficult for females to execute properly. (If there's any elite females that use the LM, who are they?)
4. There are well-established and well-documented drills and training programs based on the PM. Thus, beginning and intermediate vaulters can learn the PM technique from the get-go, without much independent experimentation needed by the vaulter or his/her coach.
5. The PM is actionable. A vaulter or his/her coach know where to start with the PM, and how to progress. With the LM, where do you start?
For these reasons, I will continue to lean towards the PM (allowing for some minor individual deviation, but not much) over the LM. This is not blind faith - it's just being pragmatic.
However, my ears are open if the merits of the LM become more well-known, well-documented, and bio-mechanically proven. After all, since he's now the indoor WR holder, he must be doing something right! We just haven't put our finger on it yet!
What are your thoughts on this?
