I'm back peeps with Pole Vault topic. Have you heard about this before? Let me guess, you heard about this before but not familiar isn't? Pole vaulting is a track and field event where a person uses a long flexible pole as an aid to jump over a bar.

The History:
- The origin was in Germany in the 1850s.
- Adopted by a gymnastic association in the Lake District region of England.
- The first recorded use of bamboo poles was in 1857.
- Started using steel pole in 1940, the flexible fiberglass and later carbon fibre.
History.
The Equipments:
- Poles.
- Crossbar.
- Pole Vault Boxes and Collars.
- Pole Vault Pit.

Phases of Pole Vault:
The pole vault technique comprises of the following phases :
- Approach.
- Plant.
- Take-off.
- Penetration.
- Rock back.
- Stretch turn.
- Bar clearance and landing.

1) Approach.
Approach phase is important which the vaulter need to maximize kinetic energy by attaining a high horizontal velocity at the end of the runway. The approach run for the novice is 10-12 strides and for the top class runner up to 18 strides from the take-off plant.Google Image.
2) Plant.
- Planting of the pole commences on the next to last contact of the left foot by pushing the pole forward.
- Bring the left arm forward. The plant must be high, fast and early.
- On contct with the right foot, raise the right arm quickly forward and upwards [like the uppercut of a boxer] until the arm is fully extended.
- At the completion of the plant, the chest leans into the pole and lead the body forwards.
- The plant seen from behind for a right handed vaulter.
- Planting of the pole commences on the next to last contact of the left foot.
- The eyes should be looking between the hands and not towards the box.

3) Take-off.
- The take-off foot should land flat-footed on the ground.
- The vaulter achieves total body stretch.
- Both arms must be stretched.
- Drive the thigh of the non take-off leg vigorously upward [1] until well after take-off took place.

4) Penetration.
- Push the left arm forwards and upwards and must not collapse.
- Freeze in the take-off position.
- The take-off leg should be pushed backwards and kept extended to aid the penetration and to assist the vaulter's swing.
- The swinging should not be too long because it will reduce the ability to reach an effective extended position on the pole.

5) Rock-back.
- Draw both legs in to the chest during rock-back [1].
- Bend the left arm slowly to bring the body and pole closer together.
- At the end of the rock-back stage, the back is roughly parallel with the ground.
- The head remains in line with the upper body.
- The rock-back position must be achieved by the time the pole reaches its maximum bend.

6) Sretch, turn & bar clearance.
- Keep the legs parallel with the pole [1]. Keep the body as staright as possible.
- The lower arm must keep the body close to the pole.
- The upper arm, which is still straight, should pull directly down the line of the pole simultaneously with the hip elevation and the pole's recoil.
- The turn commenced through the pull of both arms. Turn to the left.
- Turn the stomach towards the bar. Push off from the pole with the right arm [2].
- During the clearance the centre of gravity must be kept above the handgrip.
- To assist this, the vaulter must drop his legs by flexing at the hips.
- Allow the arms to follow the curve rather than pulling them up to avoid the chest from touching the bar.
- Depress the stoach and turn the elbows outward but not upwards. Land on the back.

Hi may I know what common disease that we can get from this sport?
ReplyDeleteHello @benacomel
DeleteThank you for the question. Do you mean common injury right? Since pole vaulting is inherently risky, the most common injury were to the lower extremities [ligament sprain and muscle tear]. For example, ankle and knee injury occurred when the athletes landed awkwardly after clearing the crossbar.
