Analysis On The Arrangement Of Complete Sets Of Aerobic Dance Under The Guidance Of The Rules Of 2017-2020 Cycle

The renewal of competition rules promotes the development of competition events.Every edition of the scoring rules of competitive aerobics formulated by the International Gymnastics Federation puts forward higher requirements for each competition to promote the development of the project.Aerobics dance has appeared four times from the first appearance of the 2012 Aerobics World Championships to the 2018 Aerobics World Championships,and the number of teams participating in this event in the domestic Aerobics Championships is also increasing year by year,thus it can be seen that aerobics dance,a big collective event,is deeply loved by athletes.By using the methods of literature review,expert interview,video analysis and mathematical statistics,this paper analyzes on the arrangement of a complete set of movements of eight teams in the final of 2018 aerobics World Championship and the top three teams in the final of 2017-2019 National Aerobics Championship.To understand the specific arrangement of complete set of music,dance content and main content of aerobic dance project under the 2017-2020 cycle scoring rules,and to explore the trend of complete set movement arrangement under the guidance of rules scientifically and rationally,to provide reference for Chinese coaches and athletes in the whole set of movement arrangement in the future,to stabilize China's leading position of aerobic dance in the world,and better grasp the development trend of aerobic dance projects in the future.The results are as follows:1.Under the guidance of the 2017-2020 cycle scoring rules,aerobic dance projects are more performant.The rules reduce the difficulty of the complete set,emphasizing the complexity of operation and the variety of space levels;the importance of the complexity and fluency of the main content requires a higher level of complete art.Compared to the 2018 Korean Aerobics Championship,the Korean team,there is still road for improvement in the artistry of the complete set of movements in my country.2.The clothing style that echoes the theme style and the proportion of male and female athletes that are reasonably arranged are ways to enhance the value of the complete set.The selection and matching of men's and women's clothing styles of excellent teams at home and abroad,consciously echoes the set of themes,enhances the sense of involvement of the referee and the audience,and better conveys the theme's style;the team reasonably matches the number of male and female athletes according to the design and expectations of the set of actions,Both rigidity and flexibility improve the display effect of the complete set.3.Appropriate sound effects can deepen the set of themes.Each excellent team selects the type of music according to the set of themes.After the post-production,the main music is merged with the second style music.The characteristics of the second style music are displayed through the different BPM values.The sound effects with memory points are added appropriately,and the action is arranged to make the scene Vivid and three-dimensional,highlighting the complete set of themes.4.The rich and varied dance content is an important factor to enhance the artistry of the set.Under the guidance of rules,the trend of arrangement of the number of complete units of aerobic dance movements of each team is 8-10;the number of units that are reasonably arranged is consistent and layered;the movement of upper and lower limbs tends to be asymmetrical movements,and more incorporating dance elements enhances its complexity and appreciation.The number of second style units tends to be greater than 4,and the arrangement appears mostly in the middle of the set,pushing the atmosphere of the stadium to a “climax”.Compared with the choice of the number of hip-hop types of excellent teams in the World Championships,the number of movement types of domestic teams is less with the proportion of dance content increases,and complex and diverse movement creation is one of the decisive factors in the final competition.5.The complexity and difficulty of the main content is the key to achieving a high score.The main content of the aerobic dance set needs to be closely related to the set theme or show difficult and complicated technical skills.Under the 2017-2020 cycle rules,the transitional connection actions of each participating team are mostly in the form of space conversion of AB and BAB.The rollover type of action reoccurs more frequently,and the originality is slightly lacking;The complexity of the movement is low and it is not easy to highlight the athlete's ability in the dynamic coordination of the domestic teams;the various lifting movements in space and form change fully demonstrate the tacit cooperation between the athletes.The throwing type of lifting in the set is the trend of movement arrangement;while skill movements combine with other,the action content presents a rich and wonderful picture effect;the proportion of difficult actions is greatly reduced,and it is no longer regarded as a key factor in determining the game results.6.Original formation and balanced use of venue enhance visual effects.In the 2018 Aerobics World Championships,the world's top ranked teams have more than 21 complete team formations.The formations change fast and have many styles.Different transition formations are cleverly used to highlight better innovation;the use of the venue is more balanced,and the visual effects are complex and changeable,in teams of South Korean and Chinese,reflecting the athletes' strong physical control ability and spatial perception ability.In contrast of the number of complete team formations of domestic participating teams is relatively small,and the novelty of team formations needs to be enhanced.
