Technical Preparation - Pole Vault flexible

Technical Preparation - Pole Vault flexible.
Technique differs from rigid rod with the following points:
1 - The launch of the stick is from the top, the right arm is extended and semiflexionado left (right-handed jumper).

2 - There is no slip of the hand from the bottom to top.

3 - The left arm is flexed about the rod in the direction towards the front and above, i.e., perpendicularly to the axis of
same, thereby forming a lever (right arm - the fulcrum of the stick). The effort in support of the right arm
remains until the end of thrust and produces the initial bending. The initial flexion is necessary to give proper direction to
bending of the rod.
