Research On The Complete Set Of Movements Of The World Aerobics Championships Aerobic Pedal Project Guided By The FIG2017 Version Of The Rules

Scoring rules are the basis of the evaluation of aerobic pedal competition,and also the yardstick to measure athletes' complete actions.The revision of the rules plays a guiding role in the development of aerobic pedal events.Since the self owned oxygen pedal project was listed as the world championships,the scoring rules of the aerobic pedal project have been revised twice.As the first version of the scoring rules for aerobic pedal project,the 2013 version of the rules does not have perfect requirements for the arrangement of athletes' complete set of actions;in the 2017 version of the rules,the fig aerobics Technical Committee revised the scoring rules in a large range.Studying the changes of new and old rules and the arrangement of aerobic pedal set of world elite sports teams before and after the implementation of the new rules are of great importance to understand and master the development trend of the aerobic pedal exercise program in the world,and it is of great significance for China to improve the quality of movement arrangement and enhance its overall competitiveness.Based on the comparative analysis of the scoring rules of 2013 and 2017,this study takes the complete set of movements of the first five teams in the final of aerobic pedal project of the 13th-15 th World Aerobics Championships as the research object,and uses the methods of literature,video observation,mathematical statistics,comparative analysis and logical analysis to analyze the main changes of the new rules,the basic situation of the final team and the competition This paper analyzes the achievements and artistic arrangement of the complete set of movements,aiming to reveal the characteristics and development trend of the arrangement of the complete set of movements of the aerobic pedal projects in various countries under the 2017 version of the rules,so as to provide certain theoretical basis for the arrangement of the aerobic pedal projects in China.The results show that:1.The new rules shorten the time of music,improve the speed of music and increase the fluctuation of music speed.The music style is mainly national music,and the two styles of music are mostly selected for integration,with strong sense of rhythm and distinct theme.2.The total number of operation units and operation actions shows a decreasing trend;the main way of board loading is point board,suction leg and parallel step,the number of steps used tends to reduce,and the types of board loading steps show stability.3.The type of transition action space is mainly b-a-b and b-c-b,and there is no obvious change in the number of transition and connection actions;the way of board change is mainlyhollow board change and mixed board change;the way of action coordination is mainly two person cooperation,and the number of two person cooperation and equipment use is increasing;the lifting action is mainly turning action,which is generally concentrated in the front and middle of the music,and the space distribution is mainly in the middle field The number of beats occupied by the lifting action tends to decrease,and the number of people on the base and the number of people on the base show stability.4.The change of pedal and athlete's formation mainly adopts symmetrical figure,mainly in place at the same time.The space type is mainly B space,and the distribution time of space level is B > A+ > A > C+ > C from large to small.The utilization of the three space(A B C)site areas shows a balance,and the utilization ratio of each area to B space is the highest.The arrangement pays more attention to highlighting features.
