Vaulters
I believe they supply them themselves and can have up to around 3 poles each.
Sergei Bubka, a Ukrainian athlete, is considered one of the most famous pole vaulters in history. He set multiple world records and won numerous championships during his career.
The pole acts like a spring, that is why it bends so much at the start of the jump.
I think it was the ancient Greeks that invented it... (hope its right!)
Yes the poles will be undamaged make sure the vaulters hands are dry and tape is dry so the vaulter doesn't slip.
Some polevaulters shave thier armpits because they thaink that it will make them run fast because of less weight. Some do it just because of religion.
The biggest improvements in pole vaulting technology have been in the pole itself. New materials allow the poles to be longer, lighter, stronger, and more flexible. This allows vaulters to go run faster, go higher, and reduces the chances of pole breakage making the dangerous sport at least a little bit safer.
many people say that a vaulters run up is what is building there potintial energy which is sortof true but in reality however much the pole bends is the potintial energy of the vault
Each person attempting the long jump will have three attempts. Competitors must have at least one legal jump to count in the final totals.
Without speed a vaulter would never get off the ground. The forward momentum built up in the run is transferred to the bend in the pole and in upward momentum used to clear the bar. Typically a pole vaulter possesses sprinters speed and are good all around athletes.
