The following is a Photo sequence of Kory Tarpenning competing in
1992 with comments by David Lease who in 1992 was a B.A.F. National Coach.
 |
Three and a half strides to take-off the running
technique is good with a complete stride action, high hips and attacking
posture. However the right hand is too low and too far back behind the vaulter.
Consequently when the transfer or plant is initiated this hand will have a long
way to travel in a limited time span, to its eventual high point. |
| |
|
 |
While the transfer (plant) may have been
initiated a little late, it has been initiated from too low a carry position
and is therefore likely to be incomplete entering take off . Comparable
photographs of Bubka and Tarasov show them carrying the pole at chest height
with the pole horizontal at this phase. An excellent attacking posture is
maintained. |
| |
|
 |
The excellent body position is continued at a
time when it is extremely difficult to do so. However, the hands are low and
the right shoulder could be further forward. |
| |
|
 |
Take off. The aim of the take-off is to push the
pole to the vertical and yet hold a suitable position so that later moves can
be carried out effectively. The take off position appears to be excellent
despite previous comments. The take-off foot is in an acceptable position
directly below the top hand. The jumping action is well demonstrated with the
drive up through the chest and left arm. The free knee has been brought through
to a correct position. It should be a limited action unlike the long or high
jumper as it is essential the hips and the take off leg remain behind the torso
for as long as possible. However, still photographs can be deceptive and I
suspect some momentum has been lost because of an incomplete arm action into
take off. An improved pole carry and transfer could see Tarpenning using a
higher grip on the pole. |
| |
|
 |
The first point to notice is that the bend is in
the top of the pole, a sign that the forces at take-off have been well
directed. The left elbow has been turned out to allow the chest to penetrate,
which it has but the right shoulder appears to have limited flexibility. The
arm action at this stage is still to push pole to vertical. However, the free
leg has been allowed to drop and this is likely to subtract time for later
movements! |
| |
|
 |
Once again, still photographs can give the wrong
impression! An excellent hang/swing position is demonstrated but it is vital to
appreciate that the athlete is moving through this position not holding it! The
left arm has pushed out, to stabilise the shoulders and the arms are now
pressing forward. Action/reaction encourages the legs to swing through on the
way to up side down. |
| |
|
 |
The arms continue to press forward and in
synchronisation the legs swing up. The free knee is rather weak and could be
driven tighter to the chest. A legacy from dropping it earlier! |
| |
|
 |
Repayment for dropping the free knee earlier is
starting to cut deep! Both legs have had to tuck to arrive upside down in time
for the anticipated pole recoil. From this point he must lever upside down
rather than swing and he never quite makes it! A straight leg swing of the take
off leg gives a faster and bigger bend to the pole with a quicker recoil. |
| |
|
 |
Tarpenning is well coordinated with good
flexibility of the lower back. He is fractionally late but is using these
talents to extricate himself well. The hips are a little low balanced by the
head which is too far forward. |
| |
|
 |
The neck should relax to allow the head to roll
back into body alignment and the arms should lengthen. These subtle movements
allow the hips to come over the shoulders for total inversion. The head
continues to be too far forward obstructing further progress. |
| |
|
 |
Tarpenning is still looking at his feet! Hence
total inversion will not be achieved. |
| |
|
 |
The body should be straight and 'tight' like an
arrow to receive the pole's recoil. The head is 'back', the athlete looking
down to the box and consequently his back is arched. |
| |
|
 |
The head back position is forcing the legs down
prematurely. A final consequence of the low. pole carry! However, Tarpenning is
completely controlled. Dropping the legs early leads to a longer, lower vault
which is safer when the bar height is not the critical factor. |
| |
|
 |
The legs must drop as the vaulter loses momentum
on leaving the pole to create rotation for the bar clearance. The head should
be down for the most effective bar clearance position. |
| |
|
 |
Tarpenning continues to rise after leaving the
pole. His head is down and body arched. The left leg bend is correct and aids
rotation around the bar. This is a practiced technique. Elbows turn out and
concentration is vital at this stage as it dictates whether the vault is
secured or lost. This one was secured! |
