Editing Pole vault (section)

=== Approach ===
During the approach the pole vaulter sprints down the runway in such a way as to achieve maximum speed and correct position to initiate [[takeoff]] at the end of the approach. A tape measure is laid on the runway so vaulters know exactly where to start their run from. Each vaulter has a certain starting distance, dependent on how many steps away from the box they start.  Top class vaulters use approaches with 18 to 22 strides, often referred to as a "step" in which every other foot is counted as one step. For example when a vaulter takes 18 strides, it would be referred to as a 9-step, as 22 strides would be an 11-step. The run-up to the vaulting pit begins forcefully with the vaulter running powerfully in a relaxed, upright position with knees lifted and torso leaning very slightly forward. Right handed vaulters will start with a step back with their right foot before starting the run, left handed vaulters with their left back to begin. The head, shoulders and hips are aligned, the vaulter increasing speed as the body becomes erect. The tip of the vaulting pole is angled higher than eye level until three paces from takeoff, when the pole tip descends efficiently, amplifying run speed as the pole is planted into the vault box. The faster the vaulter can run and the more efficient their take-off is, the greater the [[kinetic energy]] that can be achieved and used during the vault.
