| Objective:This study aims to establish the special ability index of adolescent vain up athletes,establish the special ability index,establish the evaluation system of the special ability index of the youth import,and improve the research system of the special ability of the athletes,It provides reference basis for the talent selection and scientific training of young curling players.Methods:In this study,three rounds of experts’ opinions were solicited by questionnaire survey method,the first round was mainly the collection of experts’opinions on indicators,the second and third rounds were Delphi method to quantify experts’ opinions to establish the indicator system and indicator weights,and field tests were conducted on special physical fitness indicators,and the test indicators were 20meter folding run,cross quadrant jump,sitting forward bend,grip strength,standing long jump,standing on one foot with eyes closed,and swallow balance.indicators.SPSS and EXCEL were used to describe the basic information and special physical ability data of the test subjects,and SPSSAU was used to analyze the third round of questionnaire data in a hierarchical way to derive the weights;the percentile method was used to evaluate the level of special physical ability.and the coaches’ evaluation method was used to evaluate the level of special technique,tactics and psychology,so as to finally conduct a systematic and comprehensive study on the evaluation system of special ability indexes of Chinese youth curlers.A systematic and comprehensive study was conducted on the evaluation system of special ability indexes of youth curlers in China.Results:(1)The index system of special ability was preliminarily established,including four first-level indexes,namely,special physical ability,special technique,psychology and tactics;There are 9 second-level indicators,including physical quality,jet-throwing technique,ice-sweeping technique,sliding technique,team cooperation,special cognition,individual psychology,tactical awareness and tactical decisionmaking.26 items of three-level indicators,swan respectively balance,grip strength,close your eyes stand on one foot,20 meters reverse layup,cross quadrant jump,standing long jump in succession,crook proneness,put the pot to technology,ruby line,into,hitting,flicking ice strength and ice frequency,the intention to understand other people,the collective sense of belonging,wrist orientation perception,reading ability of ice,depth perception,speed perception,attention,willpower,self-confidence,their tactics design,tactical recognition,the rationality of ruby and ruby success rate.(2)Through the analytic hierarchy process(AHP),the weight relationship among various indicators of special ability was established.Special physical ability accounted for about 36%,special technology accounted for about 23%,psychology accounted for about 30%,and tactics accounted for about 11%.Among the physical quality,20-meter return run,swipe balance and sitting body forward bending was more important and ranked in the top three.Among the special techniques,the pot-throwing technique and ice-sweeping technique are the most important,among which the pot-throwing technique and sliding stability index are more important.Among the psychological indicators,individual psychology and teamwork are the most important,while understanding others’ intentions and volitional qualities are more important.Tactical awareness is more important in tactics,of which the tactical design is the most important.(3)The comprehensive evaluation level of the index system of special ability was established,and the comprehensive evaluation of the special ability of youth curling athletes was made by percentile method and fuzzy comprehensive evaluation formula.Conclusions:(1)To establish the evaluation index,index weight and scoring standard of the special ability of Chinese youth curling athletes,and finally complete the construction of the whole system.It provides a clear,intuitive and convenient reference for coaches to evaluate the special ability of young curlers. |
