Lifting Technique - Pole Vault flexible.

Lifting Technique - Pole Vault flexible.

The jumper hangs with his right arm. Under the action of inertia produced by the approach running and push the
athlete's body moves forward with chairs. The rod continues flexing, sagging under the weight of the athlete's action
and centrifugal force produced by the pendular movement, thus increasing the bending thereof. This allows the
athlete further advance the hips (swinging) thereby increasing the bending of the rod.

The jumper must understand that the higher the speed of the race is approaching and driving force, faster
progresses and reaches maximum height. This is of paramount importance for the pole vault. The active movement and quick on Pendulum
creates the conditions for a more vertical tangent on the lower end of the stick at the same moment that
straightens. The capture action takes place precisely in this direction during the return tangent stick to their state of
origin. Consequently, the early return of the rod, which is the case of a pendulum active bit produces not only an effort
traction, as well as projects in a wrong direction. As a consequence, the highest point of the trajectory of the jumper passes
without reaching far below the bar.

Pendulum.
The athlete starts when the pendulum center of gravity thereof crosses a line joining the point and the edge of grip
bottom of the stick. In swinging, legs work as follows: the right leg with a short motion
fast without extend rises to the chest, the left moves straight, more broadly, increasing the load on the rod.
is not convenient to make the pendulum with legs straight as this requires more time and effort. The athlete will not have time
achieve the required position at the time of the return of the stick or an excessive overload, leading to their breakup.
As soon as the frog begins to elevate the legs and hips, the rod starts to bend to the left and below, due to
jumper's center of gravity have changed their position on the fulcrum. The player perceives due to movement
rotation Stick to your foothold in the dock.

Ends when the pendulum is important that the athlete's center of gravity is behind the stick and not the stick forward as
rigid, and under the grip point. In this case it achieves the maximum degree of flexion. It is time that the pole vaulter and
are under ripe to initiate action capture. The action capture is the most important phase of the jump. To
be in position ready to capture the action, the jumper's center of gravity very low in
relation to the hilt. The high placement of even hinder the return of the stick, reducing its strength in action capture.
It is also very important at the beginning of the return of the stick, extend the legs with a move rítimico (exactly in rhythm
straightening the stick), directing them jointly with your hips upward. This increases the speed of return
stick. The stick in his return to the athlete raises the slats. At this point the athlete's arms, especially the right, should not
be passive. You need to get the shoulders and the shoulders put themselves in such a way that allow to maintain the body
in the required position and make any useful traction force. The elevation is produced by the traction force exerted by the rod
during the return continues until the time when the left forearm touches the rod, i.e., is supported thereon. This
shock is very painful because the rod lifts the shoulder with great speed and strength. In general jumpers use a
elbow on his forearm since the coup that receives makes it very sensitive.

Pull.
The moment the left forearm is supported on the rod, return almost the same end but still retains
a small bending. The jumper has to wait a bit to run until the stick pulled back completely. The
athlete's performance at this stage is therefore as follows: using the left forearm as a fulcrum, with a movement
extension of the legs from the waist (helping in this case with the right forearm) takes care of your body to send
over and above the slats. The termination of this extension movement of the body must match the full movement back
Stick.

Giro and body scissors.
Using the left arm as still supporting the athlete drives with his right arm and makes the turn as follows: first
rotate the shoulders, then hips and finally the legs, thus following the correct wave motion. As soon as the athlete ended
turning his shoulders, his right hand and starts thrusting active left hand remains almost passive, since it is
considerably lower and right (in a way very different than using rigid rods that were together) their
function at this point is minimal. If the jumper's movements were executed correctly, once the push
with the right hand the effects of this broadcast is the phase of flight.

At the moment the right hand leaves the stick, as final effort, the legs of the athlete with a powerful movement to leave
falling behind the slats. The upper part of the hopper relative to the center of gravity, the lifting motion continues
passing the bar as a flight.
