 to jump even a low height bar just because of incorrect approach. Most of the successful athletes follow J shaped approach to get the effective result. In this type of approach the player’s take-off feet should be placed in the same spot relative to the close standard with the same body. It should lean on all repetition of the approach.
If we will try to take a look on this approach from the up, we will find minimum 8-10 number of strides. An athlete needs to run in an accelerating stride pattern. While approaching it, he/she should not bound steps.
Establishing the StartMark
There is quite a simple method to mark the starting point. Roughly and approximately 30”-36” out of the bar and from the take off point, the athlete runs in reverse J direction towards the starting point. Another coach will count the running steps. He will note the tenth running step foot mark on the ground and that will be the starting mark.
Now, starting from that starting point the athlete needs to run 4-5 steps in straight and next 4-5 steps in a curved J manner with a reduced bar height. In this way the athlete can really know whether the starting point is up to performance satisfaction level or not.
Starting point determination may take a whole practise session. Therefore it is advisable to note down every time the measurements to arrive at a definite conclusion. The straight forward path of running usually varies for both men and women. For men it usually ranges from 12-16 feet out from the standard whereas; for women it ranges between 9 to 13 feet.
Successful Extension of Take-off
While jumping at first the failure is certain but it has major two reasons. One is that player use to break off into the take-off area in which he loses the momentum and in other case they shallow their approaching angle. Both of the above cases result in parallel motion of the athlete with respect to bar. This should be taken care off.
On the most difficult task for a new athlete is to take off vertically. It is usually not exactly 90 degrees with respect to ground rather have some trajectory angle but the angle deviation is small. At the point of planting your take off foot on the ground, your body posture should be erect. The knee should not flex much as more flexing in the knee causes loss of speed and strength. Some other important aspects that an athlete should keep in mind while doing take-off are −
One should drive his lead leg upward parallel to the bar.
To the left of the final approach direction, the hand should be driven parallel to the bar.
Before leaving the ground the back should not be turned towards the bar.
Shoulders should not be dropped while getting nearby to the bar.
The shoulder which is nearer to the bar can be kept at a little bit more height than the other one.
Speed and jump are directly proportional to each other. More is the speed, higher will be the jump. The athlete should determine his optimal speed at which he is more comfortable with. Determination of the above is not a difficult task though. Starting from initially with each practise session, the athlete should go on increasing his speed till his foot does not get buckle while jumping.
Clearance of Bar
All the necessary actions that are required for a successful bar clearance need to be done before taking off. Because once an athlete leaves the ground it is very difficult to make any further actions over air. Rotation of head mainly becomes difficult in clearing bar but a little bit practise and correct approach will take care of that.
Analyse what body parts of yours can possibly touch the bar while you are clearing it. Such as hands, elbows, head, hip and sometimes legs too. Know exactly how to avoid that. For example it is a general piece of advice that you should not drop your head down until you cross the bar. Similarly your hands should be alongside of your body in such a manner that it will result in a huge arc. Some other general advices are −
Feet should be kicked up quickly as soon as you cross the bar.
You should not stretch your leg while moving up; instead bent your
