![]() One key concept in Petrov's technique model is the idea of a 'pre-jump', where the vaulter is supposed to be airborne before the pole is planted into the take-off box.Īlthough the technique described by Petrov has been widely accepted, slow motion video analysis (not available to Petrov when he first proposed the concept) has shown that a more accurate description of Bubka's take-off is that it is a 'simultaneous take-off'. Soviet pole vault coach, Vitaly Petrov, has used his version of vaulting technique with great success (particularly with Sergey Bubka). To find out more about pole vaulting mechanics, see:Įnergy loss in the pole vault take-off and the advantage of the flexible pole. This new understanding of pole vaulting mechanics should help coaches devise more effective take-off techniques, and it may help pole manufacturers in designing better poles. Greater energy at take-off means that the vaulter can safely use a longer pole. Results from computer simulations showed that the benefits of a flexible pole are mostly in the take-off phase.Ī flexible pole reduces the energy dissipated in the vaulter’s body during the pole plant, and it also lowers the optimum take-off angle so that the athlete loses less kinetic energy when jumping up at take-off. To understand why a vaulter can use a longer pole, I developed a model of vaulting with a flexible pole and a model of vaulting with a rigid pole. Rather, the vaulter achieves the greater height height by using a longer pole. The vaulter does not get 'flung' higher into the air. ![]() ![]() ![]() Although fibreglass vaulting poles have been around since the early 1960s, there has not been a convincing explanation of how they work.Ī pole vaulter can jump 50-90 cm higher with a flexible fibreglass pole than with the-old style poles made of steel or bamboo.Ĭontrary to popular belief, the advantage of the flexible pole has little to do with any 'catapult' effect. ![]()
