Long jump analysis

I´ll describe Dwight Phillips long jump technique. We will be able to see it in this video. 





The approach

The length of the approach is usually consistent distance for an athlete. Approaches can vary between 12 and 19 strides on the novice and intermediate levels, while at the elite level they are closer to between 20 and 22 strides.
 The exact distance and number of strides in an approach depends on the jumper's experience, sprinting technique, and conditioning level.
- In Dwight Phillip's case we can observe how he does 22 strides before jumping.

Takeoff

This phase is one of the most technical parts of the long jump. Jumpers must be conscious to place the foot flat on the ground, because jumping off either the heels or the toes negatively affects the jump.
There are four main styles of takeoff: the kick style, double-arm style, sprint takeoff, and the power sprint or bounding takeoff.
- Dwight performs the kick style which is a style where  the athlete actively cycles the leg before a full impulse has been directed into the board then landing into the pit. This requires great strength in the hamstrings.

Action in the air

- While in the air he performs 3 and 1/2 air kicks to combat the forward rotation experienced from take-off.

Landing

- As we can see, Dwight tries to land only and with his feet on the ground first so a bigger distance will be measured instead that if he landed with his feet and then with his back.
