How wide is the balance beam?
The height of the balance beam competition is meters, and the balance beam is five meters long and ten centimeters wide. The completion of the balance beam is limited by time, and the difficulty of the whole set of movements and the aerial skill string are strictly regulated. As the name implies, balance beam movement needs balance ability. Athletes will perform a series of dances and somersaults on a crossbar 0/0 cm wide from the ground. Body posture and body control are the most important. Many movements on the balance beam are similar to floor exercises, but the difficulty is getting bigger and bigger. Athletes also get on the balance beam from a springboard, and complete the action in 75-90 seconds, and get off the balance beam. The balance beam movement also needs continuity. Insufficient time or overtime, swinging, landing halfway, parking, etc. Will be deducted. As the athletes' movements become more and more difficult, the balance beam competition becomes more and more exciting. 1972, when OlgaKorbut did the backflip for the first time in the Olympic balance beam competition, someone tried to ban the use of backflip in the balance beam because it was too dangerous. Fortunately, this has not been implemented, so today we have seen more and more wonderful balance beam competitions or performances. Edit the details of the balance beam competition rules. This whole set of movements starts when your feet leave the pedal or mat. It is not allowed to add support under the pedal. When the runner does not touch the pedal/equipment in the first run-up, the runner is allowed to carry out the second run-up to complete the upper method. After the second run-up, if the runner still fails to complete French, the runner must go directly to the equipment to start the whole set of movements. Methodological errors (not appearing in the difficulty table) will be deducted directly from the arrangement score, but if the player has not touched the back pedal or equipment before, no extra points will be deducted. The whole action should not exceed 90 seconds. Timing:-The whole set of difficulty calculation starts from the timing when the player's body leaves the pedal or mat. When the player completes the action on the wood, the timing ends until the player touches the inverted gymnastics mat by lowering (or not lowering). -After 80 seconds, the player will give a prompt signal. When the last time to complete the action (90 seconds) is specified, the second signal will be sent out. -If you finish the execution and land at the second signal, you won't be fined. -If you dive and land after the second signal, you will be deducted for an extra hour (penalty), but the referee needs to take diving into account when calculating the difficulty value of this group of movements. -Overtime penalty exceeds the specified time by 0-2 seconds, and overtime penalty exceeds 2 seconds. Actions completed outside the specified time (90 seconds later) can be recognized by the referee in Group A, and the referee in Group B will score points. The timekeeper will submit the overtime hours of the players to the equipment referee chairman in the form of a written report, which will be deducted from the final score. Precious time-When the player drops the equipment after completing the action (at this time, the action has been going on for x seconds), there will be a worthless time of 10 second (the timing starts from the player's foot landing). Precious time is not included in the total assembly time (not included in the assembly action time of 90 seconds). -When the player's body leaves the gymnastics mat and returns to the equipment, the worthless time is over. -The player returns to the equipment and continues to complete the whole set of actions. At this time, the timer starts counting (indicating that the player still has x to 90 seconds to complete the action)-worthless time will be displayed on the scoreboard in the form of counting every second, and a prompt signal will be given when worthless time ends (10 second). If the player does not return the equipment within 10 seconds, the whole set is considered complete. The value of the content and composition set consists of the following actions: * Skill actions include: hand holding action, somersault action * Gymnastics (dance) action: jumping (jumping, jumping, jumping), turning, shaking, supporting action (standing/sitting/abdomen/back) 1. Specific requirements (group A) 1. A gymnastics rope consisting of at least two different jumps. 2. Vertical rotation of one foot. 3. A skill string consisting of at least two skill moves, one of which is a somersault.

4. Skill movements in different directions (sideways/forward, backward) (sideways and forward are regarded as the same direction) 5. Xiafa: No Xiafa Group A or B Xiafa: No bonus points. Group c: jiaduo group d: jiaduo 1/3/4. The connection value must be completed on wood (group A). Only direct connection can get extra points. Add additional points to point a to form additional points. 0.2 Two skill movements are connected-not including the lower method CC/DCEBEDD, including the upper method and the lower method (the lower method must have at least group D), BBDBBECCC (the two movements can be the same), BCD mixed string (gymnastics skill movements), and actions above group CC (not including the lower method)-the same skill movement can be done twice to get the connection point, but, The difficulty value of doing this action for the second time is not recognized (not the most difficult 10 move)-the following group B skill moves: combination of legs (small turn), hand turn (hand turn) and kicking hand turn, so that you can get two connection points in the complete set and the lower method. 1 arrangement (group A) and 65438+ points will be deducted. Shangfa is not an action button on the difficulty table. 3. Turn your feet to 180 and change direction more than once, or jump into the push-up button more than once. 4. Not making full use of the equipment:-Lack of near-wood action buttons. 5. There is no lower limit method button. If the somersault (horizontal somersault) in the squat action falls off the equipment without starting, or if you don't try to do the squat action at all (directly landing on your toes or falling after landing on your toes) 1: Take-off score: 1: Does not meet the specific requirements 2: No difficulty value (10 There is no squat action in the difficulty action, only 9 difficulties can be counted. If you land and fall after the start of the somersault (horizontal somersault), Example 2: Fenzi backflips (landing and falling). Deduction method 1: it does not meet the specific requirements. 2. No difficulty value (10 difficult movements, only 9 difficult movements without diving) 3. Error interpretation (Group B) Artistic interpretation (Group B) Error-lack of rhythm change-lack of confidence to complete the whole set of movements-lack of interpretation of the rhythm/rhythm change of the whole set of music-the whole set of movements lacks artistic expression, which has the following points: * The movements are not expressed by the original dance * Not suitable for the players. Completed the third run-up of 10.7, but not because of the dance movement, the pedal buckle touched. Because of the extra support, there are more support buttons on the wood with the legs sideways, which violates the technical requirements of the action. In order to prevent the wood from falling, use the wooden buckle to keep the balance (ouch! That is, the small/medium/big shake button//connection is interrupted (pause for more than 2 seconds). The preparation time of gymnastics movements is too long. Poor connection rhythm. The deduction method and skill of falling wood or dancing movements are wrong (you must go back to the equipment to judge whether it is difficult to identify according to the situation)

Degree)-One foot or two feet or on the wood when falling (action completed)-Acknowledge the difficulty value-One foot or two feet or not on the wood when falling (action completed)-Do not recognize the difficulty value-Only the fork can be used as the connection of the upper method action-The whole set can also do the upper method action (if you roll/stand upside down/support), but its action, support-support must be kept for 2 seconds to recognize its difficulty value. If the supporting action is not kept for 2 seconds, it will be reduced by one level according to the same standard action on the difficulty table (supporting for 2 seconds is enough)-in a skill string, the supporting action can be connected with the skill (somersault) action to form a connection string, and the connection bonus points will be obtained. -If you don't hold your handstand for 2 seconds when you finish, xx and XX will be reduced by one difficulty level. Onodi action-Onodi action and Alba somersault action are considered as forward action-Onodi action can be used as the first or second action in the skill string to get the connection point-Onodi can only be placed in the last action in the skill string and is considered as the same action as Onodi dance action. All dance movements (whether one-legged or two-legged) cannot be considered as difficult movements. When moving, the support position of both hands must be supported vertically. If you support your hands horizontally, the difficulty of moving will be reduced by one level. Hands close to left hand and right hand IIIII * lllll * * (I'm really creative in expressing graphics in this way) VVIIII (hands close to each other as far as possible, but not crossing) Hands front and back support position iiivvii * * iiivvii The above two hand support methods are to correctly support the history of hand balance beam [edit this paragraph], which originated in Rome BC, and was used as an auxiliary equipment for gymnastics training by German gymnasts at the end of 18. At first, the balance beam was round, and its two ends and middle part were supported by brackets. /kloc-At the beginning of the 9th century, German gymnast Gutz Mutz designed the balance beam as a plane and put it on the ground. 1845 became a women's gymnastics event. The balance beam is a square batten, with a length of 5m, a width of10cm and a height of 0m above the ground. In the balance beam final, at most two athletes from each team participate in the competition. Only the top eight or six on the team balance beam are eligible to participate. Only better than voluntary movement. Half of the total scores of the required movements and optional movements of the team athletes, plus the results of the optional movements in the balance beam finals, are the final scores, and the highest scores rank first. The perfect score is 20. Since the 1992 Olympic Games, team points are no longer brought into individual events, and the ranking is only determined by the competition results of optional movements. The perfect score is 10. 1952 is listed as an Olympic event. The balance beam is one of the women's gymnastics events, which has been listed as a competition event since 1952 Olympic Games. The balance beam originated in Germany in the18th century and later spread to Europe and America. The narrow surface of the balance beam requires athletes to complete their movements accurately and control their body balance. The movements of the balance beam include various jumps, turns, waves, balance, modeling and skill tumbling, and form a complete set of movements. 1952 is listed as an Olympic event. In 1980s, the movement of balance beam developed rapidly, and a lot of movements in floor exercise were transplanted to the balance beam. The balance beam movement has developed from a combination of static and dynamic to a competitive event that focuses on sports and strives for stability in difficulties. In the Olympic balance beam final, each team has at most two athletes. Only the top 8 athletes before the team competition are eligible to participate, which is only better than the optional action. 1992 At the beginning of the Olympic Games, the team performance was not brought into individual events, but only the performance of self-selected movements was used to judge the ranking, with a full score of 10. There is no upper limit for full marks now. Specification of balance beam [edit this paragraph] The balance beam is 5 meters long and 5 meters wide, and the height of the wood can be raised and lowered as needed. The height of the official competition is 100 meters. The completion time of the balance beam is limited, and the difficulty of the whole set of movements and the aerial skill string are strictly regulated. Balance beam champion [edit this paragraph] Bai Yang (1988 Italian balance beam champion in international gymnastics competition, 1990 Belgian world cup balance beam champion) Ye Fan (champion of the 37th gymnastics world championship) Liu Xuan (1992 uneven bars champion in national gymnastics championship). 1993, the seventh national games in Beijing, won the women's team championship. 1May, 1995, the women's individual all-around competition in China Cup International Gymnastics Competition won the women's balance beam, floor exercise and women's individual all-around championship. 1In May 1997, South Korea won the women's individual all-around and balance beam championship in the gymnastics competition of the Second East Asian Games. 1In April, 1998, Canada won the World Cup women's uneven bars championship for the first time. 1September, 1998, Tianjin China Cup International Gymnastics Competition won the women's team championship. 1998 65438+February, Bangkok, Thailand 13 Asian Games won the women's team championship, women's individual all-around and women's balance beam championship. When the champion of Sydney Olympic Games in 2000 mentioned women's gymnastics in China, many people would first think of uneven bars. In fact, the balance beam and China women's gymnastics have the same fate. In the past 20 years, female athletes in China won 8 gold medals, 8 silver medals and 3 bronze medals in three competitions, and the number of world champions even surpassed that of uneven bars (7), making them the first gold medal winner in women's gymnastics in China. As early as 198 1 World Championships, China's athletes showed good balance beam skills, and Chen and Wu won the second and third place respectively. In the 1990 World Cup gymnastics competition, Bai Yang won the first balance beam world champion in China with high scores. Lu Li, a teenager who won the uneven bars championship in the final of the Barcelona Olympic Games, won the silver medal on the balance beam, which was the first balance beam medal won by a gymnast from China at the Olympic Games. Eight years later, at the Sydney Olympic Games, Liu Xuan, who was a late bloomer, drew a perfect end to his gymnastics career with a set of unparalleled difficult movements, and at the same time became the first Olympic balance beam champion in the history of gymnastics in China. Over the years, seven people, including Bai Yang, Mo Huilan, Liu Xuan, Ling Jie, Sun, Li Ya, etc., have won the "three-race" balance beam championship eight times, and China athletes have also become a unique scenery on the balance beam field. It is worth mentioning that in the World Gymnastics Championships held in Aarhus, Denmark in 2007, the China women's team unexpectedly defeated the United States and won the team championship for the first time in history. In this decisive battle, it was on the balance beam, the third event, that the female athletes in China turned around their disadvantages with extraordinary performance and laid a solid foundation for winning the championship.
