Children Swimming Team Body Shape And Performance Of The Relationship Of Shandong Dong-ying City

body shape as swimming Players important reference indicators play a crucialrole in the development and impact of Athletes. The study by the literature data,expert interviews, expert questionnaire, measurement method and mathematicalstatistics method, Dongying City, Shandong Province Yucai School childrenswimming team members84people (including40male members and44femaleplayers) as the main research object, respectively, compared with the100breaststroke,100butterfly,200freestyle and400medley men and women of the body shapedifferences in indicators (original indicators, derive indicators) to build a childrenswimmers body shape evaluation weighting model Finally, Dongying City, ShandongProvince, Children’s Men’s100meters breaststroke, for example, the major playersbody shape indicators and athletic performance gray relational analysis. Aims toidentify the main factors affecting children swimming sports results, scientificevaluation of children swimmers body shape, and provide reference basis forswimmer selection. The conclusions are as follows:(1) Children’s swimming team evaluation19original indicators of body shape, thederived indicators12, a total of31.(2)Swimmers body shape indices characteristic of children of different projects viewfrom Dongying City, Shandong Province: the different projects of the men’s swimteam in the height, weight, Quetelet index, sitting height/height×100, percentage ofbody fat, the presence of a significant difference (0.01<P <0.05), refers to thedistance between the very significant difference (P <0.01), while there is nosignificant difference in other indicators; children of female swimmers: height,distance, wide hips, Hector Levin index, sitting height/height×100, Bust/height×100and percentage of body fat exist significant sex difference (0.01<P <0.05), bodymass index there is a very significant difference (P <0.01), while other indicators donot There is a significant difference.(3)Children of different projects, Dongying City, Shandong Province, swimmersbody shape indicators through the normal distribution test, found that a strongrelationship exists between many indicators, a strong correlation exists between thevariables, and a high degree of overlap.
