Long Jump: Jumpers
built 779 days ago
If you are not an experienced long jumper it is best to use a short approach `in training so that you jump high. Increase the length and speed of approach as you become more skilful. But good technique is not enough; you must always be striving to produce more power in order to jump higher off a faster approach. Begin off a 7 stride approach and work back through 11, 15, to a 19 stride approach. The number of strides in the full run up will depend on how soon you can achieve the fastest speed off which you can jump high.

The sail technique is one of the most basic long jump techniques practiced by competitors. After the takeoff phase is complete, the jumper immediately lifts the legs into a toe-touching position. This is useful for the novice jumper, as it allows the competitor to move into the landing position early. The downside of this technique is that it does not counter the body’s natural tendency to rotate too far forward.

From the advent of the modern Olympics in 1896 through the reign of Carl Lewis, the United States dominated the men's long jump. But the country that produced an assembly line of great jumpers - Jesse Owens, Ralph Boston, Bob Beamon, Mike Powell and Lewis - suddenly lost its bearings in the late 1990s.

A runup that is too long will result in the jumper reaching maximum speed before takeoff. Often this will result in loss of velocity in the last two strides. Conversely, a runup that is too short will not allow the jumper to reach maximum velocity. A increase in velocity at the board of 4 inches per second (this is comparable to going from a 14.0 100M to a 13.8) will increase the jump distance by up to 2%. Speed at the board is the most important single item in the horizontal jumps.
