Research On The Characteristics Of Sport Dance Students' Physical Ability And Evaluation System In Sport Colleges

At present, sports dance is developing rapidly. And sports dance students are took as driving force for sustained and healthy development of sport dance. Researchers should grasp the item characteristics of the sport, explore its special physical characteristics and build a physical ability evaluation system of sport dance students of sports colleges for carrying on objective evaluation and effective monitoring for them, thereby strengthening the teaching training of the teacher and the trainer and comprehensively improving the competitive ability of the students. This paper tries to use the methods such as the documentation data, questionnaire survey, expert interview, test method, mathematical method and logical reasoning method, take the sport dance students of Wuhan Institute of Physical Education as the object of study.From the perspective of the evaluation, studying the students' physical ability obtains the following results.1. The physical ability of sport dance students in the sport colleges refers to the ability which the students bear the load and adapt to environmental changes in dance. It is the general reflection of their body shape, organism function and movement quality.2. The physical ability evaluation system includes three parts like indicator, weight and criteria in the structure, four steps like identifying evaluation goals and objectives, identifying evaluating indicators, identifying the weight and designing evaluation criteria.3. On the base of the documentation data, expert interview and statistical optimization, the paper attempts to get the one, two, third-level physical ability indicators, use principal component analysis to find the representing third-level indicators, establish each indicators' weight finally and formulate evaluation criteria by percentile method.4. The physical ability evaluation system of sport dance students in sport colleges is set up preliminary to provide the reference for their evaluation.
