Research On The Construction Of Evaluation Index System Of Sports Dance Artistic Expressiveness

Sports dance is a kind of difficult and beautiful sports which is graded in six aspects,such as basic technique,dance style,musical expressiveness,choreography,field effect and on-the-spot play.In order to get the best result in sports dance competition,we must pursue exquisite basic technique,more creative choreography,the best playing field effect,and extremely infectious expressive power.Therefore,this study is guided by the rules of sports dance competition scoring,based on literature,combined with the experience of sports training,the study adopts literature method,Delphi method,mathematical statistics method and other research methods,and systematically constructs the evaluation index system of sports dance artistic expression on the basis of systematic principle,combination of qualitative and quantitative principles and maneuverability.The results show that:(1)The research results show that the evaluation index system of sports dance art expressiveness is composed of five first-level indexes,such as body form,music expression,modeling expression,basic technique and choreography,and 18 second-level indexes,such as body condition and facial expression.(2)The weights of the first-level evaluation indexes of sports dance art expressive power obtained through the analytic hierarchy process are: body shape 0.0331,music expression0.4025,styling performance 0.0554,basic technology 0.1065,dance choreography 0.4025.The weights of the second-level evaluation indicators are: physical condition 0.1429,facial expression 0.4286,physical fitness 0.4286,music rhythm 0.2583,music style 0.1047,dance and music fusion 0.6370,posture and posture 0.3858,styling design 0.1753,clothing and apparel 0.3858,makeup With 0.0531,special body literacy 0.2583,basic dance skills 0.6370,action proficiency 0.1047,action innovation 0.0184,action type 0.3150,action difficulty0.0366,action rhythm 0.3150,routine combination 0.3150.(3)According to the overall weight of the evaluation index system of sports dance art performance,the top five indicators are the fusion of dance and music,action type,action rhythm,routine combination,and music rhythm,so sports dance players are trained in daily Can be properly biased.(4)Through the correlation analysis test and practice test on the evaluation index system of sports dance art performance,it is found that the constructed evaluation index system ofsports dance art performance is more reasonable,and the overall universality is better.High promotion value.
