Research On The Body Shape Character Of Guangdong Female Synchronized Swimmers

Synchronized swimming is one of the Difficulty and Aesthetic Items,has higher requirement for the body shape.In recent years,The overall level of synchronized swimming in China has been significantly improved,if we want to maintain our competitive edge in the long run,must be selected scientifically according to the characteristics of the project,and make scientific evaluation and prediction of their body shape,and then it is used to guide the development of training.This study takes women's synchronized swimmers in Guangdong Preparing for the 2017 Thirteenth National Games as the research object,employed the literature,expert interview,questionnaire survey,measurement and mathematical statistics in this paper,on the basis of previous studies,according to the expert consultation,indicator primary election combined with expert consultation,index reelection and measurement by the Delphi method,refining the typical indicators that can reflect the physical characteristics of the body with the main factor analysis method,and determine the weight of these indicators;finally,constructing the evaluation standard of body shape and evaluated.The purpose of this study is to establish an evaluation model that accords with the physical characteristics of female synchronized swimmers in Guangdong province,scientific evaluation of body shape,it will provide theoretical basis for scientific selection and training in the future.Through the study,we get the following conclusions:1.After evaluation by experts,the original index was evaluated by the experts.9 indexes were selected as the selection index.The length factor,the width factor,the fullness factor and the degree factor were determined by factor analysis,and the 4 common factors were determined.Among them,leg length,calf girth,and shoulder width are the typical indicators of the 4 factors mentioned above.2.The percentile method and the five-grade evaluation method were used to establish the scoring and rating standards for the body shape of women figure swimmers in Guangdong Province.The results showed that the body shape conditions of women figure swimmers in Guangdong Province were not very good.The comprehensive score of body shape reached 7.14% of the first-class,14.29% of the middle-class and 14.29% of the first-class,respectively.It accounts for 57.14%,14.29% of the middle and lower class,and 7.14% of the lower class.3.According to the theory of sports measurement and evaluation,the "percentile method" is adopted to establish the score and evaluation criteria for the body shape of the female pattern swimmers in Guangdong province.The results show that the physical form condition of the female pattern swimmers in Guangdong is not very good,and the comprehensive score of the body form reaches the top class ratio of 7.14%.The proportion of middle and upper class accounts for 35.71%,reaching 50% of the middle level,and 7.14% of the middle and lower class.4.The test results show that the index system and evaluation standard of the body shape evaluation of Guangdong female pattern swimmers in this study are more reasonable.The test results conform to the actual situation of the female synchronized swimmers in Guangdong Province,which can reflect the physical characteristics of the athletes objectively and accurately.
