The parallel bars originated in Germany. In 1811, German gymnast Jan first installed this kind of gymnastics equipment at the Hasenhead Gymnasium outside Berlin. Originally a gymnastics training method, it became an independent competition in the 184s. The parallel bars are composed of four columns and two parallel wooden bars. The horizontal bar is 3.5 meters long, and the spacing and height of the two bars can be adjusted. In the final of parallel bars, at most two athletes from each team will participate in the competition, and only those who rank in the top eight or six in the parallel bars in the team competition are eligible to participate. Only better than optional movements. Half of the total scores of the athletes' required movements and optional movements in the team competition, plus the scores of the optional movements in the parallel bars finals, are ranked as the final scores, and the ones with the highest scores are ranked first. The perfect score is 2 points. Since the 1992 Olympic Games, team points have not been brought into individual events, but only the results of self-selected movements have been used to determine the ranking. It was listed as an Olympic event in 1896. Since the new rules of gymnastics were adopted in 26, there is no upper limit for scoring. It consists of two parts: a and b. A is divided into difficulty points, with no upper limit. B is a complete score, out of 1. Eight teams in the team preliminaries qualify for the finals. There are no more than two players in each team.
one of the men's competitive gymnastics events. At the beginning of the 19th century, the parallel bars have become a popular fitness equipment in Europe, and were later stereotyped as gymnastics equipment by German gymnast F.L. Young. After 1812, it became a traditional exercise program of German gymnastics school. In the mid-19th century, the theory of Swedish gymnastics school flowed into Germany. H. Rotstein, the principal of the Royal Central Sports School in Berlin, who studied gymnastics in Sweden, thought that horizontal bars and parallel bars were harmful to teenagers' physiology, and excluded the traditional German horizontal bars and parallel bars from gymnastics teaching. Around 186, there was an argument. Three people from Berlin Gymnastics Federation wrote a protest against the cancellation of singles and parallel bars, and 19 doctors, including the medical counselor, made a special study and thought that parallel bars conformed to human physiological characteristics. Germany's highest medical institution accepted the latter's argument, and since then the parallel bars have gained a firm foothold in gymnastics. Since the 1st Olympic Games, parallel bars have been listed as a gymnastics competition.
according to the rules, the complete set of movements of parallel bars should include swing, swing, flexion and extension, arc swing, loop, somersault and static force. When athletes do a complete set of movements, they must mainly swing and fly, and they can also have appropriate static and hard movements. At the beginning of the 2th century, there were many static movements in parallel bars. After that, the proportion of swinging movements gradually increased. In the 193s, there were movements such as swinging forward by 18 degrees to become a support, and flipping back to become a support. At the 1936 Olympic Games, German athlete K. Frey's optional movements included a back flip with legs swinging more and more into support. In the 195s and 196s, the technical movements of parallel bars were improved, such as increasing the amplitude, turning forward by 18 degrees into handstand, backflip into handstand, and so on. The front pendulum turns 36 degrees into a handstand; The method of somersault rotation type increases and so on. In the mid-197s, two-week somersault was widely used, and two-week somersault plus twist had also appeared, and the connection range between the upper and lower bars was also increased.
After 195s, some outstanding gymnasts from Japan, Italy, the Soviet Union, the United States and China made many innovations in parallel bars. China athletes are also good at supporting and swinging movements of parallel bars, and have also improved their hanging movements. At the Hartford International Gymnastics Invitational Tournament in 198, China athlete Cai Huanzong turned into a complete set of movements with the support as the core after the handstand turned 36, and won the parallel bars championship with 19.75 points. In the same year, in the World Cup gymnastics competition, China's athlete Li Yuejiu performed the original action of forward somersault and swinging his legs back into arm support, and won the title of parallel bars.
