Thank you Kirk for reinforcing that the pull I describe is continuously applied. Once it is established that the pole pulls continuously on the vaulter and the vaulter pulls continuously on the pole from the "Get Go " after take-off the importance of emphasizing the "Hochsprung "...

In this post I conclude the development of a conceptual framework based on considering the propulsion of the total system COM as the focal point of the technical challenge to be met by the vaulter in the pole support phase of the vaulting sequential process. In a previous post I indicated a three ba...

The Centripetal Force generated by the vaulter’s swing action in phase 1 and 2 of pole support can be decomposed into a radial and tangential component acting on the total system COM to produce a Torque (F tangential Vector x Pendulum Length Vector rB) in the clockwise direction sufficient in magnit...

The picture sequence and diagram below of Sergei Bubka in the 1st phase of pole support shows the action pattern he adopted for this particular vault (1st ever 6.00m Clearance). Total system pendulum and the vaulter pendulum on the connecting pole to Axis B.jpg The inset in the diagram represents th...

Once the vaulter has broken take-off foot ground contact and the pole tip is contacting the rear wall of the planting box (start of phase 1 of pole support) the inertia of the total system centre of mass (COM total system) is applied to the pole via each hand gripping the pole. Sliding Vector concep...

PVstudent I have been reading your posts for some time and am an admirer of your approach to building a mathematical model of the modern pole vault. However, your attempt to fit the double pendulum to the real world leads to errors. Why? The modern vault is not a double pendulum as you are describi...

My apologies to readers for some inadvertent omissions and a minor error on one of the diagrams in my previous post. I have edited / amended it slightly in the hope it will be easier to read and corrected the error. I believe the approach I am presenting will ultimately provide a way of observing an...

The next two diagrams illustrate how to achieve preparation effectiveness to minimize Momentum Exchange Transmission Losses from vaulter to the pole (and vice versa) at the instant the toes of the take-off foot break ground contact. In the first two diagrams below please note that what is being sche...

It is with deep sorrow that I am reporting the news, just received, that Alan George Launder aka "Altius" has died whilst in England. My condolences to Jenny, David, Richard and all in Alan's family on their loss. Altius , through his contributions on the forums of PVP, to the world of pol...

Who better to illustrate the operation of Robert Hooke’s Law relating to the pole acting as a spring mechanism than Steve Hooker Australia’s former Olympic and World Champion Pole Vaulter! Hooke's Law and Pole Spring Stiffness.jpg In the photo and the diagram insert showing the pole attached to the ...

Analyses based on energy considerations, because they involve mere scalar quantities, shed little light on the time, spatial location elements of the vaulter efforts during the pole support phases of the vault. Energy only analyses are inadequate in informing coaches and vaulters as to the how, when...

Thank you for positive support and I am now ready to prepare the ground to the comparative analysis of Bubka's and Lavillenie"s technical similarities and differences from a biomechanical perspective. What follows are what I believe to be well accepted basic understandings of facts underpinning...
