Shot put is one of the track and field sports that uses the strength of human body to push a certain weight of shot put from shoulder to arm. ?
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. Men's and women's shot put were listed as Olympic events in 1896 and 1948 respectively. In 1950s, PARRY OBRIEN, an American athlete, invented the back sliding shot put technique, which was called "a revolution in the history of shot put".
The highest organization of shot put in the world is World Track and Field, which was founded in 19 12 and headquartered in Monaco, with the aim of developing world track and field sports.
