Research On The Arrangement Of The Complete Set Of Movements For The Collective Events Of The 13th And 14th World Aerobics Championships

Competitive aerobics is a sports event with a continuous,complex and high strength complete set of movements in the accompaniment of music.Its complete set of movements must show competitive ability,such as flexibility,balance,strength,and so on,through the combination of gymnastics,difficulty,transition and lift.Therefore,the perfect set of movements will be the key to achieving good results.Using the methods of literature,video analysis,mathematical statistics and logical analysis,this paper makes a comparative analysis of the performance and arrangement of the five sports teams before the final of the two finals of the thirteenth,Fourteenth World calisthenics Championships.The purpose of this study is to find out the high level of the present collective project.The characteristics and advantages and disadvantages of the arrangement of horizontal sports teams are discussed in order to provide some rationalization proposals for the development of collective events in China.The results of the study show that:1.The average score of the Fourteenth World Championships is slightly lower than that of the thirteenth.The difficulties and the completion points of the teams are improved,the competition is more intense and the flow of medals is dispersed.2.The total number of units in the thirteenth,Fourteenth World Championships group is between 9×8 beats and 12×8 beats,and the general operation is more than that of high strength,and the number of aerobics is concentrated in 3-4 combinations.The symmetrical proportion of the upper limbs decreased from 0.40 in the thirteenth session to 0.47 in the fourteenth session.The symmetrical ratio of the lower limbs movement was 0.26,and there was no significant difference.The Chinese team should increase the diversity and complexity of the upper limbs on the premise of keeping the advantage of symmetrical ratio of the lower limbs.3.In the complete set of movements,mainly 2A-1B-5C-2D difficulty combination structure layout,the C group difficulty of the highest use rate,in the two games are 48% and 54%respectively,and mainly concentrated in the longitudinal leg jump group,the group jump group and the leg jump group.The choice of difficulty action is concentrated on 0.7 points and 0.6points of difficulty movements,and their utilization rates are 60% and 58% respectively.The Chinese team should arrange the difficulty layout reasonably while ensuring the completion quality of difficult movements.4.The number of transition connections is mainly concentrated in 8-10 times,and the time distribution is more uniform.The lifts are mainly distributed in the middle and end of the complete set of movements,and for lifts increased the proportion of time.China team shouldincrease the space transformation of lifts,increase the proportion of lifts.5.The main groups are mainly 16-22 change times in the arrangement of complete sets of movements,and the conversion of B-C-B type is the main type in space conversion,and the change times of the formation are mainly concentrated in 12-15 times.The Chinese team should be more abundant in the layout of mobile routes,and make rational use of the playing field.6.The length of the music team is concentrated between 89s-95s;the number of rhythms of music is concentrated between 27.5×8 beats and 31.5×8 beats;the frequency of complete sets of movements is concentrated in 2.44 pats / seconds to 2.68 pats / seconds;the selection of music section is dominated by a single segment,supplemented by the splicing of 2-3 segments.
