Research On The Formation Change Of Sports Dance In Line-up Based On The Rule Of Formal Beauty

As a new sport item,sports dance is deeply loved by people.Under the background of the rapid development of sports dance,the sports dance has gradually come into the public field of vision.As a collective item in sports dance,the formation change and the overall visual effect need to be considered in the arrangement.The formation change is not only an important factor that affects the competition results,but also an important factor that reflects the level of technique and arrangement,it is instructive to improve the competitive level and the composition of the whole set of movements in the formation dance.The rule of formal beauty is an important basis for judging whether the form of presentation conforms to the standard of beauty.In this paper,by means of literature,video analysis,expert interview,Mathematical Statistics and logical analysis,from the perspective of formal aesthetics,this paper makes a statistical analysis of the formation changes of the top six teams in WDSF World Team Dance Championship in 2019 and seven teams in Beijing Dance Academy in 2018,this paper summarizes the characteristics and rules of the formation change of each team,and finally puts forward the thinking of the formation design of the formation dance,the research conclusions are as follows:(1)The rules of form beauty in the formation change of sports dance consist of symmetry and balance,change and unity,contrast and harmony,rhythm and rhythm.The pattern,number,speed,route,changing way and the reasonable cooperation of the field and space of the formation can enhance the ornamental and competitive ability of the whole set of movements to some extent.(2)The technical gap between the teams is not obvious,the arrangement is the key factor affecting the final results.The most frequently used formation of outstanding teams in foreign countries is the regular formation.The proper use of other formations can better reflect the artistry of formation changes.Regular changes are the most commonly used form of change,combined with other changes in the formation of the combination of more clever changes.(3)The number of formation changes is best controlled in the range of 40-45 times in the formation dance competition.The average formation change speed of each team is 8.6 s/time,the moving route is more balanced,and the changes are various,the central area is more utilized than the quadrangle area,and the A-B space is used the most,and the A-C space is used the least.(4)The changing law of formation formation is an important factor in formation composition,which is mainly manifested in the following aspects: abundant formation patterns,various forms of formation formation,balanced use of venue,full use of space,prominent theme music,etc..(5)There is a certain gap in the formation arrangement between the representative teams of our country and the excellent teams of foreign countries.The formation changes the frequency to be few,the in-situ movement is too many,the complete set movement whole fluidity needs to strengthen.The central area of the site is used too often,neglecting the use of the quadrangle,the combination of formation and space,and the room for improvement.
