The high jump, in contrast to numerous contemporary Track & Field events,http://alevworks.com/freerun40.php, does not have roots in the Ancient Olympiad. Rather, its first recorded event took place in 19th century Scotland. (Though there were similar events in the Olympiad and it is contested that the high jump has been occurring since ancient Greece, the Scottish version was almost identical, if not more elementary, than the jump of today.) In the good old days, jumpers gained momentum and strength by scissoring over the bar.
Today the high jump is taken on in a much more technical fashion. The bar is set at a predetermined height and jumpers attempt to clear the bar. There are special high jump shoes with spiked heels used for gaining additional traction in the run up to the foul line. The approach to the bar is often more important than the actual take off. If you approach at the wrong angle or run without enough force,http://theelephantshop.com/coralrun.php, clearing the bar is more of a challenge. Jumpers run at an angle of 30-40 degrees,http://harrietts.com.au/nikefree5blackwomens.php, and it takes between 8 and 13 strides to get to the jumping line. There are several different styles of jumping. The most popular is the Fosbury flop, but there are also western rolls and straddle techniques. All use centripetal force to hoist the body over the bar.
As with most track events,http://www.lbruning.com/shop/bestfreerun4.php, jumpers have three attempts at each height. Heights are raised 2 cm after each round,http://www.labrunette.fr/ladyfootlocker.php, and only those who clear the bar move on to the next round. The winner is he or she who clears the tallest height. If there is a tie, the winner is he who has the fewest failed attempts at that height.
