High Jump - Track & Field
The high jump is a track and field event where an athlete must launch himself over a horizontal bar without knocking it over. The high jump athlete may touch the bar as long as he does not knock it off the uprights. The technique that athletes used to clear the bar has changed a lot over the years. The biggest change to the event occurred after the addition of crossbar. The soft mattress changed the way players could land so that they would not get hurt. Before the foam mattress of the other sides, the jumpers would have to jump in such a way so that they would not land on their head, back, or shoulders. Earlier versions of the track and field high jump had athletes jumping with the technique more similar to the hurdles than the jump with the back to the bar that we usually see today.
The high jump track and field event consists of clearing a horizontal bar without knocking it off the uprights. The athlete uses his own body to clear the crossbar, no other springs or accessories are used like the pole vault. The event originated with the Celtics hundreds of years ago, and was restored in track and field competitions in the 1800s. The men's high jump was added to the Olympics in 1896 in Athens. The women's high jump became an official Olympic event in the 1928 Amsterdam games.
The High Jump.
The order of the athletes for jumping is chosen at random before the start of competition. In the first couple of rounds, officials raise the horizontal bar 5cm at a time, then 2cm in later rounds. To advance beyond the first round, the athlete must clear the high jump in one of three attempts, or else he is eliminated. High jump athletes have 90 seconds to make the jump. An athlete is removed from competition after three consecutive failures. The jump must be made off one foot only.
The Sequence of Events.
The athlete times his jump and distance from the bar so that they will make a specific number of strides, at a specific speed before they launch themselves for its glory. Usually, the high jumper begins his run about 12 meters from the crossbar. The athlete accelerates towards the bar for about 7 long strides before he begins to turn his body in the last 3 to 5 strides. The athlete must maintain a high velocity in the final strides to make a powerful launch in competitive competitions.
In the second to last stride, the push off leg fully extends while the other leg is bent. The athlete next pushes off with the fully extended leg and rotates so that his back is pointed directly at the crossbar. The athlete propels over the horizontal bar heel first. By tipping his shoulders back and bringing his heels under his thighs, the athlete arches his body, enabling his hips to rise over the crossbar. When his hips have passed the bar, the jumper flexes his hips bringing his torso and legs back and over the bar. This curve and flexion of the hips creates an angle that allows the athlete to clear the bar, without knocking it over. By paintball products.
