According to official records, the origin of basketball is/kloc-the ball game of Aztecs in Mexico in the 6th century, which is the predecessor of basketball. When the solid rubber ball is thrown into the stone circle hanging high on one side of the sports ground, the players of the winning team are eligible to get the clothes of the audience; The captain of the losing team will be beheaded. Modern basketball was invented by Canadian naismith in 189 1 at the YMCA Training School in Springfield, Massachusetts, USA. At that time, he wanted to design an activity that could not only maintain the game skills, but also be carried out in specific occasions such as the gym. At first, this kind of ball was called naismith ball, but he thought it was more suitable to be called basketball. Because this sport is made of peach branches and hung on the wall, and the ball is thrown into the basket, the name "basketball" is more vivid. Because the basket is hung at a height of 3 meters from the ground, the bottom of the basket is closed, so every time you throw a ball, you have to climb a special ladder to take it out of the basket. At that time, the screen was made of barbed wire and the ball was replaced by a football. It was not until 1906 that the basket was changed into a hollow ring and the branch basket was replaced by a metal basket. The number of people who take part in the basketball game is not fixed at first, usually 7 or 9 people per team, and sometimes as many as 50 people. The size of the site is not fixed, there is no boundary line, and it can be moved at will. 189 1 year, in Springfield, Massachusetts, a PE teacher named james smith accepted a task given by the head of the physical education department to invent a team sports task that can be played indoors in winter and arouse interest. Therefore, Smith combined lacrosse played by Indians with football played by British people to design a sport that can be played indoors. Once, Smith nailed an empty basket on each side of the school gymnasium, so that players divided into two teams could try to throw the ball into the basket of the other team to decide the outcome. At first, there were 7 people in each team, and the competition time was 3 quarters, each quarter was 20 minutes. During the game, once the ball is thrown into the basket, the game will stop, and the special picker will climb the ladder and take the ball out of the basket. By 1893, the basketball stand and the attached net bag have been used. After the player hits the ball, the referee pulls a rope on the net bag to let the ball fall. Later, in order to prevent the audience in the stands from affecting the players' pitching, backboards were set up. About 19 13 started to use bottomless baskets. From 65438 to 0936, basketball was officially listed as an Olympic sport. 1892 65438+1October 20th, the first competition in history was held at the annual meeting in Ching Tien, Massachusetts, USA. At first, two baskets were hung on the walls of the indoor gymnasium at about 10 feet, which was the origin of basketball. Every time a player hits the target, the ball stops in the basket. He must climb the ladder and take it out to continue the game. Soon after, the peach basket was replaced by metal and it took two years. The YMCA's promotion of basketball has spread all over the country in a few years since 1894 was introduced to Tianjin. Nowadays, basketball is not only the main teaching material of school physical education, but also the favorite of young friends. Basketball is one of the main teaching materials of school physical education, which can not only train individuals to run, jump, throw, turn around and make an emergency stop. Hand-eye coordination can stimulate mutual assistance and cooperation between individuals and teams. It is undeniable that due to the vigorous development of the concept of strong basketball, the competition in basketball is becoming more and more fierce, and there are more and more opportunities for physical collision. In order to cope with the ever-changing court environment and deal with the basic actions of personal attack and defense quickly and stably, it is necessary to improve the proficiency of vertical and horizontal courts and enjoy the fun of basketball.
