Construction Of Evaluation Index System Of Dance Sports’ Artistic Expression

As an international and competitive sports,Dance Sport not only pays attention to the external form of expression,but also emphasizes the embodiment of the inner spiritual implication.Sports dancers should not only have exquisite skills,but also require strong appeal and artistic expression.Nowadays,the overall level of competitive Dance Sport in China is increasingly prominent in international competitions.Compared with the world’s high level countries,there is still a big gap,which mainly due to the poor performance of artistic expression.The dancers’ artistic expression directly affects the aritistic score of Chinese sport dancers,and then affects the final competition results.In recent years,the research on Dance Sport in our country shows that the artistic expression has been paid more and more attention by the majority of scholars,and these studies provide strong theoretical support and method guidance for this paper.The purpose of this study is to promote the artistic expression of Dance Sport in the process of training and refereeing to be more scientific,comprehensive and reasonable,so as to promote the better development of Dance Sport in China,but also enrich the artistic expression of Dance Sport related theoretical research.Through the research methods of literature,Delphi,analytic hierarchy process,logic analysis and mathematical statistics,this paper analyzes the artistic expression of sports dancers from different angles,such as the art,sports training,and other different angles of analysis,It aims to establish a scientific and reasonable evaluation index system of Dance Sport artistic expression.The main conclusions are as follows :1.This article uses the literature method to conclude the concrete connotation of the artistic expression of Dance Sport: the ability of sports dancers to express their inner emotion and dance connotation by using dance movements,body display,facial expression,special skills and other external expressions in the process of performance and competition.2.This paper uses Delphi method to verify the evaluation index of primary election,and finally establishes the evaluation index system of Dance Sport’s art expression,which consists of two first-level indicators,five second-level indicators and 18 third-level indicators.3.Using Analytic Hierarchy Process(AHP),a pairwise contrast matrix is constructed to calculate the weight of each index,and the total ranking of the indexes is obtained.In the first level index,the weight coefficient of internal factor and external factor is high,it can be seen that these two indexes play an important role in the artistic expression of sports dance,but the weight coefficient of internal factor is slightly higher than that of external factor,which indicates that internal factor has more influence on the artistic expression of Dance Sport.4.Among the secondary indicators,the weight coefficient of competitive level is higher,which is more critical to the influence of Dance Sport’s artistic expression;the weight coefficient of music interpretation and partner cooperation is basically equal,they play an important role in the artistic expression of Dance Sport;the expression style and movement arrangement affect the artistic expression to some extent,but the influence degree is lower than that of other secondary indexes.5.Among the three-level indicators,physical fitness,basic skills,the degree of tacit cooperation between dance partners,the rhythm of music,body display,movement and music fit,and other indicators,these indicators play an important role in the artistic expression of Dance Sport.The weight coefficient of other indexes is relatively low,which has little influence on the expression of Dance Sport,but it also should be paid attention to in the process of training,competition and evaluation.
