To effectively set up a takeoff, the cyclic running pattern and heel recovery will be broken on the last two steps of the approach.
To the casual observer the long jump would appear to be one of the most basic of all track & field events. Athletes run up to a takeoff board and without going past it jump as far as they can into a sandpit. Many of us have seen the picture of long time world record holder Bob Beamon soaring over 29 feet in the 1968 Olympics. Regardless of the level your athletes are at they will need to 1) Accelerate to maximum controllable speed 2) Transition this approach into a takeoff and 3) Land the jump in as efficient a manner as possible.
Acceleration And Maximum Speed
In recent years a great deal as been written about these two topics. The ability to accelerate quickly is developed by addressing technique and strength (starting and explosive).
