Overcoming obstacles is a basic life skill formed by human beings in their long-term production and struggle with nature. Hurdling, as a track and field sport, evolved from the basic skills of crossing obstacles.
Ethnicity
Hurdles first appeared in Britain in the19th century. At that time, it was called obstacle course. It was a men's event, and ordinary fences were used as obstacles. Later, a wooden fence frame was buried underground, and later it was changed into a support for sawing firewood. Crossing this obstacle is not only dangerous, but also prone to injury accidents, which also hinders the improvement of hurdle technology.
The development of history
At the beginning of the 20th century, a movable T-shaped hurdle appeared, which promoted the development of hurdle technology. 1935 adopts L-shaped railing, and the bottom of the railing is heavy. As long as the railing is impacted by 3.6-4 kilograms, it will fall forward. This structure of railings has been used until now.
1837, the first hurdle race for college students was held in Britain.
1896 The first Olympic Games, with hurdles. At that time, the hurdle technique was not perfect, but the front legs were bent around the hurdle, so the results were not high. The champion score of this sports meeting is 17 "6. 1900 In the second Olympic Games, the hurdle technique was improved and the "hurdle step" technique was created. American athletes won the 1 10 meter hurdle championship with the score of15 "4. In the same year, 1 10 meter hurdles were introduced to China.
1908 In the 4th Olympic Games, American athletes adopted the posture of leaning forward over the hurdles, and improved the movement of crossing their legs (not directly pulling forward after stepping on the ground, but crossing the hurdles through the side front), and won the championship with the score of 15 ".
19 10 China listed it as a national sports event.
1920 ——1922 Canadian athletes not only used the upper body to lean forward to help the hurdles avoid the body's center of gravity rising too high, but also used the hurdle technique of leaning forward with one arm to help the upper body lean forward, and won the seventh Olympic champion with the score of14 "8.
1936 American athletes swing their legs high when hurdling, which plays a great role in landing quickly after hurdling and improves their skills. They won the first 1 1 Olympic champion with the score of14 "2. 1959 mobilized transportation to west Germany and set a world record of 13''2 (manual timing). It was not until 1973 that American athletes set a new record with13 "1. By 1980, the world record is electric timing 13 "and manual timing 16".
Since 1970s, due to the appearance of plastic track, new changes have taken place in hurdle race technology. This change is the transition from hurdle race to hurdle race, and the whole speed is improved (the average speed of 1 100 meter hurdle race is 8-9 meters per second, and the average speed of women's 100 meter hurdle race is 8 meters per second), and the absolute speed of "hurdle race" is also improved.
China's rise
2 1 century, China men's 1 10 meter hurdles have sprung up! At the 2004 Athens Olympic Games, China's Liu Xiang took12 "91! In 2006, Liu Xiang broke the world record with a score of12 "88". Later, many world-class athletes appeared in China!

Bascoul of France won the runner-up in 13.30 seconds, and Braswell of Barbados won the third place in 13.30 seconds.
Project rules
1 10 meter column This project consists of 1 10 runway and 10 column above the runway, where the distance between each column is 10 yard (9. 14 meters). Athletes should cross this 10 hurdle and cross the finish line respectively.
Men's 1 100 meter hurdle height is 106 cm, and 400 meter hurdle height is 9 1.4 cm. The height of women's 100 meter hurdle is 84 cm, and the height of 400 meter hurdle is 76.2 cm. During the competition, athletes must cross 10 hurdles. Pushing down a hurdle with other parts of your body is not a foul, except for deliberately pushing or kicking it with your hands.
110m hurdles consist of110m straights and10m runway hurdles, where the distance between each hurdle is10m (9.14m). Athletes should cross these 10 hurdles respectively and cross the finish line first.
In the men's 1 100 meter hurdle race, the hurdle height is 106.7 cm (different from the women's 400 meter hurdles and 100 meter hurdles). During the competition, athletes must cross the 10 hurdle, and all other parts of their bodies will touch the hurdle except pushing or kicking it with their hands. Some experts predict that the limit of human 1 10 meter hurdles is 12 seconds 78.
