Beth Harris Level 4 Pole Vault Coach explains the perfect Pole Vault Technique. Start the run up with the Pole up high and in line with the body. This takes the strain off the arms during the run up.
To achieve the perfect Pole Vault technique the pole should start in line with the skeleton so that the weight of the pole is not being carried purely by the arms but the Vaulter is actually using their frame to carry the pole. Start with a nice strong running action and a smooth pole drop throughout the run up. The take off foot should be just under the right arm and a left leg fast swings to inversion.
Through take off and inversion a really good right arm left leg connection is needed, this means driving the right arm and kicking the left leg. At the top of the vault make sure to keep driving the feet towards the sky and keep the body tension.
