In this game you will encounter problems of take off especially.Basically there are 5 components of a long jump:
>1st:Run-up.in this part you need to start up with an accelerating run.This acceleration should first be linear and then it should be 0 i mean you will have to maintain a constant but a high velocity of about 7 to 8 mts per second
>2nd:Approaching jump board:*When your off with a healthy run-up you need to orient yourself such that your chest will be perpendicular to the ground.
It implies your legs need to be totally flat for about several micro seconds and make sure that it does not CROSS the jump board as it will be regarded as foul.
>3rd:Take off.Now that you have gained enough momentum you need to follow these:
*Do not try to push the ground horizontally backward at this moment as even though it seems, you may be pushed forward you wont be !insted your momentum will be transfered to ground and your horizontal range will be affected!
Instead feel the bouncing effect and rake the stride!Remember your last stride is not similar to running stride.
*When you take the final stride you need to make an angle of 30 to 35 degree with the ground
>4th:Flight.*Keep your chest at a slight angled position.
Now wave your hands and legs alternatively,i mean like you tend to push water,its all much the same but here you are trying to clear the air resistance.
>5th:Landing.Now you need to land on the sandy surface and transfer all your body momentum to the ground.
*So first make your legs and chest parallel to ground as though you are trying to touch your toes without bending your knees.Finally after landing never try to rest with your hands backward but try to keep it in front or aside you as the reandings are taken from where you placed the tip of your body,no matter if it is your hand.And make sure you get up and walk to the front,do not fallback while you get up.
*Then to move even further, bend your knees as soon as you fall! this ensures that your tip of toe followed by your back touch the same tip while falling.This is clearly illustrated in video of famous jumper named Saladino
Little more mechanics:
The above diagram shows the variation of range with the angle.
Maximum range is observable for the angle 45degrees.But to obtain that angle you will have to give a higher vertical force to ground so that its reaction will be high and this will reduce momentum as more reaction implies you are transfering more momentum to the ground.thus your forward tendency reduces!
Thus the optimum angle will be around 30 to 35 degrees.
We have some legends of long jump who used a particular characteristic feature for jumping:
*In Carl lewis v/s Mike powell a final record of 8.95 was set!
Here Carl used his sprinting abilities thus gaining momentum and Mike took a proper take off as mentioned above and also kept his chest and legs parallel to ground unlike carl who kept his chest perpendicular to the ground.Also carl did not keep his foot flat to ground for a longer timeduring his his jump.
*But in saladinos jump of 8.93 mts,he took a proper lift and best possible landing but kept his initial velocity low.
Digging even more deeper:
*When you place your leg for the last stride,start with your ankel then middle of your foot then finally the toe, but remember the most important part is you need to do this with an uninterrupted flow!.
*To improve your jump, just as you take your last stride,toe the ground,i mean try to give a last additional push with your toe.
Now this might help you to have a proper long jump
