In-Depth Information
An athlete engaged in the high jump takes a run-up along a curving path
to approach the bar at an oblique angle. The body is held at an angle to the
ground before straightening up while simultaneously turning away from the
obstacle just before launching from the ground in order for the spine to face
the bar as the figure rolls over the obstacle.
A long jumper demonstrates a very different technique with a much longer
and faster run-up and a flailing action in the legs during the phase when the
jumper is off the ground.
A triple jumper also takes a long run-up at great speed but is required to
include a separate and distinctive striding action as part of the jump and prior
to the main launching into the air.
Jumping straight up into the air from a standing position requires a different
technique again. In this instance all the height is gained through vertical
movement with no run-up. To gain maximum height, the jumper squats low
to the ground to gain more thrust on the upward action by fully flexing and
extending the legs.
