Frankly, which one is better? I've seen both methods implemented by elite vaulters, but Bubka uses the Petrov. Is the petrov more effective?

That's a good question... The Petrov model gets the best of both worlds; one trailing leg and one drive knee... It gets the pole moving as well as creating a load with the trail leg. The two leg swing moves the pole much less, but can put much more load into the pole, and the tuck gets the pole moving much more. Which one is better? I'm no expert, so I can't tell you. But most likely, the Petrov model of the swing is better, since that's what most coaches know how to teach, and there are most likely many more reasons. Now people like Galfione just happen to have a coach to teach them a different method, the two leg swing, and were able to use it well enough to achieve greatness. Here's a good thread to read:

With all do respect... PLEASE use the search function at the top of the page to look into the Petrov model.

This horse has been dead a long time, long and well beaten.

There have been some really interesting discussions about this topic.

now from what i have gathered.. you can execute the petrov model even with a bent trail leg (i.e. Giuseppe Gibilisco). The trail leg tuck/long swing seems to be classified by altius as a difference in style, not technical model.

the key to the petrov model is a free, tall take off, swinging long to the chord of the pole, role the pelvis up, and then cover the pole. he can jump in a correct me if im wrong, but thats what i seemed to gather from his video

Yes indeed but it is even better to ROLL the pelvis up.

lol.. i try my best what can i say

"The trail leg tuck/long swing seems to be classified by altius as a difference in style, not technical model. "

In this case it is a fault because the Petrov technical model is based on the notion of putting maximum possible energy into the pole continuously throughout the vault. To do this in the second phase the trail leg has to swing through straight so as to generate max centripetal force through the top hand - if the leg flexes before it reaches the chord of the pole, energy is lost. This small element of technique costs a lot of vaulters - unfortunately jeff hartwig is one who has been handicapped by this problem. While it may seem a tiny thing remember that the vault is composed of an infinite number of tiny 'things' - where force can be generated and efficiently applied. If Jeff had resolved this he would have moved up there with tarasov and markov -can still do so if he sorts it out.

As long as the body is swinging on the pole around the top hand the further the take off toe is away from the hand the better -even after the athlete passes the chord of the pole.

The same principle is used by hammer throwers who try to keep the hammer head as far from the axis of rotation of the body as possible - now that will confuse you!! But keep up the good work -what about some more video -have you improved your cadence over the last six???

So i have a question. You swing long and keep your trail leg as straight as possible, all the way to the pole, correct? my question is, do you swing your shins to the pole and THEN begin to straighten your body out, moving your hips up the pole? OR can you begin to straighten out your body a little before your shins hit the pole and not lose energy? Because right now my swing and pull are actually overlapping in their phases.

i will start having some video for you soon. i ended my season on august third. i just needed to get away from it for a bit. the last 6 were getting better at my last meet. i was hitting the same mid but brought my takeoff step out about 4-5 inches.

i start full training again next week so i will be sending footage soon!!

tucking directly from take off is by far the most efficient way of storing energy into the pole. this puts all your weight together into one smaller area and drives longer and better into the bend. then basically frog leg off the top to get that extra umph!! to get big blow from the pole.

errrm....no

Tucking may make you swing up faster, but it will not do so with more energy.

Think of it this way--would you rather be kicked in the nuts by a midget, or by a guy that's 2m tall?

Although tucking will help cover the pole faster, there is a potential to stall the pole out.
