Shot put competition area:
Throwing area
In the shot put, discus and hammer throw competitions, athletes all stand in the throwing circle and start throwing. The throwing ring is surrounded by metal edges, 6 mm thick, and the top is painted white. When throwing, athletes must not touch the top of the iron rib or the ground outside the throwing circle. The diameter of the throwing circle of shot put and hammer throw is 2. 135 meters, and the throwing circle of discus is slightly larger, with a diameter of 2.5 meters.
The ground in the ring is made of cement or anti-slip material with similar hardness, and the height is slightly lower than the ground height. Put a wooden toe board in front of the shot put ring to prevent athletes from slipping out of the ring. Athletes can touch the inside of the toe board, but not the top of the toe board.
Falling area
In all throwing competitions, the landing area is a flat fan-shaped area composed of lawns or other substances that can leave traces. Each sector is separated by a 5 cm wide white line (this 5 cm wide white line is not included in the landing zone). The fan angle of the shot put, hammer throw and discus throw area is 34.92 degrees, and the javelin throw is about 29 degrees.

The origin of shot put:
Originated from ancient human activities of hunting animals or defending attacks with stones. Modern shot put started from 65438 to 2004, when European artillery pushed and threw shells in their leisure time in the 1940s, and gradually became a sport.
The production of shot put has experienced the process of using iron, lead and lead in external iron. In the official competition, the weight of men's shot put is 7.26 kg, and the diameter is 1 1~ 13 cm. The women's shot put weighs 4 kg and has a diameter of 9.5 ~ 1 1 cm. There is no fixed way to put the shot in the early stage, and it can be put in place or run-up; Can be pushed with one hand or both hands; There are also competitions classified by weight.
At first, the shot put technique was used in situ, and then it gradually developed to lateral push and upper push. In 1950s, American athlete O 'Brien invented the back sliding shot put technique, which was called "a revolution in the history of shot put".
In 1970s, the Soviet athlete Barry Sinkov invented the spinning shot put technique, but it was difficult to control the body balance after spinning, so far only a few athletes have used it. During the competition, the athlete should use one hand to push the ball from the shoulder and make a circle with a diameter of 2. 135 meters. The shot put must fall within the angle line of the landing area to be effective.
Men's and women's shot put were listed as Olympic events in 1896 and 1948 respectively.
The weight of the shot put is 7.257 kilograms. 1340, the world's first artillery appeared in Europe, using gunpowder guns. The shell is made of lead and looks like a ball. The weight of a shell is 16 pounds, or 7.257 kilograms. When soldiers are resting, they push shells around to play, which gradually developed into a physical exercise method and was later included in track and field events.
