The high Jump plant or Takeoff, is the phase where we convert the horizontal velocity (speed) we have generated into height.
Some authors and coaches consider this to be the most important phase in the high jump (10). This phase is very short (around 0.18 seconds) and during this phase, the athlete may achieve vertical velocities of up to four meters per second (3, 16).
The athlete's second-to-last stride during the approach run (called the penultimate stride) will be longer than the last stride and will begin the lowering of the athlete's center of gravity by flexing the knee. During the last stride, the foot is slapped down and the knee is extended. The athlete is leaning backwards so that the hips are ahead of the shoulders. The leg during the last stride acts as a lever while the other leg is swung forward and up allowing the athlete to jump
