Of course the free take is a giant hoax. It is just another attempt by Bubka and his former coach Petrov to lead American vaulters down the wrong path. It is a dastardly plot in line with Bubka's arranging for the pegs to be shortened, time to be cut and 'voltzing' to be eliminated - all to ensure that his record is not broken for a few years - especially by a US vaulter. Well that appears to represent a one view of the situation - not an informed one - but who cares??
However if this is the case you have to first accept that Petrov knows very little about the vault, that I and many other coaches - including incidentally Peter McGinnis - have been hoodwinked, and that Bubka either does not know what he tried to do as vaulter or is in fact a liar. You also have to ignore the video evidence of both Bubka and many other jumpers, notably Dima Markov. More importantly you have to ignore the biomechanical logic of a free take off and its extension the prejump.
However readers may be interested in the following snippet gleaned from the IOC medical commission who carried out some studies in Sydney. In Bulletin Number 8, January 2002 on page 23 Abstract Number 7 "Kinematics and kinetics in pole vaulting: Energy storage and energy return", produced by researchers Peter Bruggemann of Germany and P. V. Komi of Finland it states -
"The purpose of this paper was to improve vaulting technique while at the same time reducing the potential for lower back injuries (Does that ring a few bells folks??).
Results.
"Two techniques are used in pole vaulting. In technique 1 the pole hits the ground(sic) while both of the athletes feet (sic) are still on the ground. In technique 2 the grip on the pole is slightly higher and the athlete's feet are just off the ground when the pole hits the surface for the first time. The difference between the two techniques is only 50 milliseconds. Technique 1 puts more stress on the spine and does not maximise the jump height potential. Technique 2 is not only safer on the spine, but it allows for higher jumps."
Allowing for mistakes in translation the message is pretty clear but the full transcript of the study has not been released - again i am sure this has been done to confuse US vaulters! Incidentally the researchers are going to follow this study up in Helsinki where the box will be instrumented - i believe for the first time in a major competition.
