Hurdling
–
Hurdling is the act of running and jumping over an obstacle at speed. In the early 19th century, hurdlers ran at and jumped over each hurdle, after experimenting with different step patterns the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles was decided on. In the sport of athletics, hurdling forms the basis of a number track, in these events, a series of barriers known as hurdles are set at precisely measured heights and distances which each athlete must pass by running over. Failure to pass over, by passing under, or intentionally knocking over hurdles will result in disqualification, accidental knocking over of hurdles is not cause for disqualification, but the hurdles are weighted to make doing so disadvantageous. Hurdle design improvements were made in 1935, when they developed the L-shaped hurdle, with this shape, the athlete could hit the hurdle and it will tip down, clearing the athletes path. The two shorter distances take place on the straight of a track, while the 400 m version covers one whole lap of a standard oval track. Events over shorter distances are commonly held at indoor track and field events. Women historically competed in the 80 meters hurdles at the Olympics in the mid-20th century, hurdles race are also part of combined events contests, including the decathlon and heptathlon. In track races, hurdles are normally between 68–107 cm in height, and vary depending on the age and gender of the hurdler, events from 50 to 110 meters are technically known as high hurdles races, while longer competitions are low hurdles races. The track hurdles events are forms of sprinting competitions, although the 400 m version is less anaerobic in nature, a hurdling technique can also be found in the steeplechase, although in this event athletes are also permitted to step on the barrier to clear it. Similarly, in cross country running athletes may hurdle over various natural obstacles, such as logs, mounds of earth, horse racing has its own variant of hurdle racing, with similar principles. The standard sprint or short hurdle race is 110 meters for men and 100 meters for women, the standard amount of steps to the first hurdle should be 8. The standard long hurdle race is 400 meters for men and women. Each of these races is run over ten hurdles and they are all Olympic events, the mens 200 meters low hurdles event was on the Olympic athletics programme for the 1900 and 1904 Summer Olympics. These low hurdles events were widely participated in the part of the 20th century. However, beyond these two Olympic outings, they never gained a consistent place at international competitions and became increasing rare after the 1960s and this 10-hurdle race continues to be run in places such as Norway. Other distances are run, particularly indoors but occasionally outdoors, the sprint hurdle race indoors is usually 60 meters for both men and women, although races 55 meters or 50 meters long are sometimes run, especially in the United States. A60 meter indoor race is run over 5 hurdles, a shorter race may occasionally have only 4 hurdles
