The Study Of Evaluation Index Model Of Latin Dance Specialty Students’ Special Athletic Qualities

The increasingly fierce Latin Dance competitions,as one of the sports dance events,have placed a greater demand on the special athletic level of the Latin Dance athletes.The special athletic quality has become the most critical factor in affecting the athletes’ performance,yet colleges and universities,as a significant part of the cultivation of Latin Dance reserve talents,previously made vague evaluation on the sports quality of Latin Dance athletes.With the progress of science and technology plus the improvement of scientific research,evaluating correctly the sports quality of the Latin Dance specialty students can not only make scientific theoretical guidance on thier daily training and competitions,but also improve the objectivity of the selection exams of Latin Dance in colleges and universities,and avoid the status quo in which coaches and examiners evaluate subjectively on athletes’ sports quality.This subject takes 52 sports dance students majoring in Latin Dance as the research object,by using the documentation method,expert investigation method,experimental method and mathematical statistics method,constructs the evaluation system of Latin Dance specialty students’ sports quality and establishes the evaluation standard.The main conclusions are as follows:(1)Use the documentation method and the expert investigation method to determine qualities like strength,speed,stamina,flexibility,agility,coordination plus their organic combination as the Latin Dance athletes’ sports quality,take these six special athletic qualities as the primary research indexes,and then formulate 34 secondary indexes relying on the primary indexes.(2)After the expert screening,select 18 out of the 34 indexes as the test indexes,test 52 Latin Dance specialty students,apply the Principle Component Analysis to the test data,determine that the evaluation index model of Latin Dance specialty students consists of Special Speed and Force Factor,Special Speed Factor,Special Endurance Factor,Special Comprehensive Factor and Special Balance Factor,and select typical indicators of each factor including vertical jump,push-ups to exhaustion,10-second jive flick,20-second double-lift,sit-and-reach,hexagonal jump and single leg stance to establish the evaluation index model for Latin Dance specialty students’ athletic quality.(3)On the basis of the evaluation index model,weight system and mean value model,according to the test data,further formulate the individual and comprehensive scores of each evaluation index by using the percentile method,and further construct the evaluation index system for special athletic quality.
