The pole acts like a spring, that is why it bends so much at the start of the jump.
I believe they supply them themselves and can have up to around 3 poles each.
Vaulters
I don't know of any "pole volter", but of "pole vaulters", the most famous is Sergei Bubka.
A pole vaulter has kinetic energy as they run with speed, potential energy as they use the pole to propel themselves upwards, and gravitational potential energy as they reach the peak of their jump.
I think it was the ancient Greeks that invented it... (hope its right!)
Punting
The device used in pole vaulting to lift the participant is called a "pole." Athletes use a flexible pole, typically made of fiberglass or carbon fiber, to propel themselves over a high bar. The pole acts as a lever, converting the athlete's forward momentum into vertical lift as they vault over the bar.
Traditionally. with a long pole
A barge pole is a variety of quant pole used to propel a barge through the water.
Yes the poles will be undamaged make sure the vaulters hands are dry and tape is dry so the vaulter doesn't slip.
The high jump and pole vault are both track and field events focused on jumping over a horizontal bar, but they differ significantly in technique and equipment. In the high jump, athletes leap over the bar without any assistance, using their own strength and technique to clear the height. In contrast, pole vault competitors use a flexible pole to propel themselves over the bar, allowing them to achieve greater heights. Additionally, the approaches and landing areas for the two events differ, with pole vault requiring a landing pit and high jump typically utilizing a cushioned mat.
