Construction Of Performance Capacity Index System For Excellent Youth Latin Athletes

Latin dance is a branch of dance sport,with strong athletics and performance characteristics.Since the World Dancesport Federation was accepted by the International Olympic Committee in 1997,dance sport has appeared frequently in various influential and international comprehensive sports events.From 1998 as a performance item of Bangkok Asian Games to 2010 as a formal event in Guangzhou Asian Games,and as a new item in the 2018 Youth Olympic Games,dance sport has entered the Olympic Games steadily.Besides,the judging criteria has gradually developed more meticulously and precisely.Unique dancing style and stable performance capacity of players have become one of the most important criteria for judging.Latin dance has developed rapidly over the past 30 years in China,with numerous young players emerging on the international stage.However,there is still a distinctive gap between Chinese players and other top international players at the same age.Lacking understanding in Latin dance culture and music,Chinese players tend to show weak performance in the competition.According to current evaluation standard(3.0)adopted by dance sport competitions,performance capacity has played a more prominent role in competitions.This paper studies the performance capacity of young Latin dancers,tries to explore concrete contents,and constructs the index system in order to enrich both training practice and theoretical research.It is supposed to provide theoretical support for the training young Latin dancers,and specifically helps them improve their athletic performance to achieve better performance.This paper preliminarily establishes the content indicators of teenager Latin dancers' performance capacity with literature material law and expert interview method,combining with the features of teenagers'physical and mental development,the technical features and related theories.In addition,the index system of performance capacity of excellent young Latin dancers was constructed through questionnaire survey,data collation and analysis.Then the system is analyzed in detail and the weights of indicators at all levels are determined by combining with mathematical statistics and AHP analytic hierarchy process.The research results are as follows:1.Performance capacity refers to Latin dancers' ability to express themselves and infect their audiences by accurately using Latin dance skills in the competition,through good music perception and unified body language inside and outside.2.The establishment of index system for teenager players' performance capacity.According to the Latin dance technical features,the principle of teenagers' physical and mental development and related theories,the following conclusions can be drawn through the analytic hierarchy process and other research methods:performance capacity index system of excellent young players,consists of two first-level indicators(competitive ability and artistic expression),five second-level indicators(basic Latin dance skills,movement texture in sports,special physical fitness,performance of participating behavior,personality and style display)and 36 third-level indicators,including on-the-spot competitive state,rhythm and rhythm,deductive music,body posture,Latin dance movements,etc.3.Using AHP analytic hierarchy process,the weights of each index are obtained according to the results of experts' investigation on the importance of two or two indexes at the same level.The weight coefficient of each indicator is finally established through the consistency test.The index with the larger coefficient is determined as the main influencing indicator,and it is concluded that the competitive ability and artistic performance of the first-level index are equally important for performance capacity,both of which are 0.5;the top three secondary indicators are the basic skills of Latin dance,action texture and special physical fitness.Among all,the greatest weight is the basic technical index of Latin dance,with a coefficient of 0.3094,while action texture 0.2485,and special physical fitness 0.1906.Therefore,it reflects the importance of each indicator in the system clearly and intuitively,and provides theoretical support for coaches and players to carry out training and practice.
