U.S. Pole Vault Academy
Basics - The Rock Back
- Once sufficient penetration is achieved, the vaulter should be stretched
like a huge rubber band in the "inverted-C"
position from his top hand, through his back, down to his trail leg. The
vaulter then needs to do 2 things:
- Row (violently) with the shoulders, keeping
the shoulders as the axis of rotation.
What this means is that both arms -- fully extended (locked out) -- make
a wide sweeping motion from over your head - out in front of you - down
to where your bottom (left) arm becomes parallel with your legs (hand
roughly at your knees, just to the left of your left knee). Once the left
arm becomes parallel to your left knee - keeping the right arm fully extended
- the left arm bends at the elbow and the left hand travels up the body
along the left leg to the waist. At this point the left hand should be
on the left hip - and the right arm is fully extended - the right hand
should be at the knees (between the legs). This now positions you very
close to the pole which is critical since the more the pole uncoils,
the closer you need to be to the pole in order to maximize the transition
of energy from the pole back to the vaulter - and focus that energy upward
in height.
You are now positioned properly to execute the pull & turn.
The Row is crucial to the ability to compress a large pole and accounts
for over 1/3 of the transition of energy from the run into the pole. It
is what keeps the pole moving through the jump - something we call "pole-speed".
If you find yourself stalling, chances are good that you are not rowing,
but rather have passive arms that lock up and stop the pole speed - causing
the stall.
Also - in concert with the Row is the Swing explained next:
- Swing the trail leg (violently) in the
largest possible sweeping arc to generate momentum to rock back.
- Keep in mind that you must continue to rock back as the pole uncoils,
otherwise the pole will "shoot" you out of your rocked back position
and you will not achieve your maximum height.
