Study On The Characteristics Of Balance Beam Movement Arrangement Of World Elite Female Gymnasts In Tokyo Olympic Cycle

Competitive gymnastics is considered to be one of China’s strengths,and the women’s balance beam is China’s main gold medal event in the international competition.With the upcoming Tokyo Olympic Games,China’s balance beam also ushered in a new opportunity.International gymnastics federation of gymnastics rules are updated every four years,starting from the new rules,the Tokyo Olympic Games cycle outstanding female athletes in the world the balance beam of complete sets of movements,find our country athletes on the balance beam arranges the existing advantages and disadvantages of project,provide a beneficial reference for the Chinese gymnastic team Tokyo Olympic Games and using for reference.This study to Tokyo Olympic cycle world elite athletes the balance beam complete action choreography as the research object,by the 2016 Olympics in Rio,47,48,49 world gymnastics championship in the balance beam single 32 sets of eight athletes before the final balance beam of complete sets of movements as observation object,as part of the Chinese gymnastics team outstanding balance beam complete action for comparative observation object,By the methods of literature material,expert interview method,video observation,comparative analysis and mathematical statistics research out of the Tokyo Olympic cycle rule changes,the balance beam,create the outstanding athletes in the world the balance beam of complete sets of difficulty action usage and concluded the characteristics,mainly analyzes the action of excellent athletes the balance beam structure,the difficulty of movement,movement type,connection and completion,This paper records and verifies the data of upper stroke,wood stroke and lower stroke as well as the complete set of movements,compares and analyzes the advantages and disadvantages of the complete set of movements on the balance beam for Chinese athletes,and puts forward some suggestions for the national team to prepare for the Tokyo Olympic Games.The research results are as follows:(1)the Tokyo Olympic Games cycle rules after implementation,dance class action was significantly increased trend,skill class action,though still as women’s balance beam the main characteristics of excellent athletes in the complete set of movements,but use the number gradually decreases,and the balance beam competition from predominantly skills class action gradually transition to the skill class and dancing class action balanced development as the main characteristics.(2)Switching legs to jump on(D)is the main difficulty movement of the balance beam,accounting for 29.16%;Group C and D are the two most frequently used movements,each accounting for 50% of the skill movements.In the jump,group C’s exchange leg jump has always been the main feature of the complete set of movements from last Olympic cycle to this Olympic cycle,and the choice of difficulty is mainly concentrated in two difficulty groups B and D,among which the exchange leg jump of group D’s 180 ° turn has also become the first choice in the complete set of movements.The backbend of the lower method is the main arrangement feature of the set.(3)Back somersault and front somersault are the most frequently used movements in the wood,among which,the most common type of choreography is backward somersault,such as small somersault and pull lift.Finally,the main feature of the arrangement is that all the action types of the lower method are backward action.(4)The connection form of the current technique is mainly two-connection,but gradually develops to three-connection;In the second combination,0.1 bonus points were won for back spring(B+ E)and 0.2 bonus points were won for front hand and front group(B+ D),and 0.2bonus points were won for the third combination of small and middle spring and back spring(B+C+C).In the jump,the exchange leg jump catches the exchange leg jump and turns 180°(C+D)to obtain 0.1 connection bonus points.The selection frequency is the highest,accounting for 35.29;Mixed strings are used frequently in complete sets,and the arrangement mode is mainly in the form of D+B getting 0.1 connection bonus point and D+B+B getting0.2 connection bonus point.The form of two connection is the main direction of mixed connection.High-level athletes are better at using three connection as the arrangement mode of complete sets.(5)At present,China’s main athletes have an advantage in the difficulty score of the balance beam(D).They are good at using various types of dance jumps on the beam,with standard movements and well-placed rings.In addition,Chinese coaches fully grasp and utilize the rules of the balance beam,so that Chinese athletes can closely adhere to the connection points in terms of the way and type of connection,and China’s movement connection points are among the best in the competition.The shortcoming lies in that most of the players in our country lack of high point difficulty in the wood and tend to be more conservative in the use of difficulty.The vertical movement is low in difficulty and the movement type is simple.Finally,the complete set of movements score E is not high,and foreign elite athletes make fewer mistakes in complete sets of movements,have relatively high completion score and are confident in their performance.
