Research On The Structure Characteristics Of Competitive Ability In Wheelchair Curling

Purpose of researchWith the approaching of the Beijing Winter Paralympic Games in 2022,the wheelchair curling event,as the dominant event in China's winter Paralympic Games,has won the outstanding results of the first gold medal and the world championship in the history of the Paralympic Games,and has the potential to win gold again.However,the particularity of the project limits its social attention,the investment of scientific research is weak,and there is little research on the theory of wheelchair curling at home and abroad,especially in the context of preparing for the Olympic Games,the research on the structure of athletes' competitive ability and the characteristics of its elements is almost zero.In 2018,the Ministry of Science and Technology organized the project "Winter Paralympic Sports Project Special Training Theory and A Study on the Construction of Supporting Platform,YF306501-1..2018 This article is one of its sub-topics research content,aims to study the chair curling project competitive ability structure and its element characteristic,carries on the beneficial exploration to enrich this project special training theory.Research methodBased on the literature method,this paper constructs the competitive ability structure elements of wheelchair curling project,selects and determines the competitive ability structure elements of wheelchair curling project by Delphi method and questionnaire method,calculates the mean and ranking of each level factor weight score by mathematical statistics method,calculates the correlation coefficient of two rounds of data by SPSS23.0 statistics software,tests the validity of expert score,measures the basic sports ability index of wheelchair curling athletes by test method,and summarizes and summarizes the competitive characteristics of wheelchair curling competitive ability structure by logic analysis method.Research conclusions1.Wheelchair curling competitive ability structure five elements,in turn for sportstechnology,sports tactics,sports psychology,sports intelligence and competitive physical fitness.There are 10 items of secondary elements,which are technical application,tactical application,tactical consciousness,technical action,motor will,motor perception,motor thinking,motor observation,physical ability and physical disorder in turn.There are 30three-level elements,13 of which are more than the middle value(0.0335)of the weight of three-level structural elements,followed by technical application effect,team tactical cooperation,pot-throwing action requirements,on-site tactical response,technical application purpose,pot-throwing action structure,command tactics arrangement,game emotional control,their own tactical design,competitive decisive confidence,field space-time perception,opponent tactics identification and competition situation judgment.There are 17 general elements which are less than the intermediate value,in order of competition time observation,competitive state control,technical application type,throwing pot action perception,curling movement perception,tactical application purpose,throwing pot action type,dilemma pressure response,on-site response decision,skill response observation,competitive state observation,proprioceptive system,special coordination quality,special strength quality,auxiliary equipment requirements,physical dysfunction and physical disability category.2.The characteristics of competitive ability structure of wheelchair curling sports are accuracy of technical application effect,tacit understanding of team tactics cooperation,rationality of throwing pot action requirement,timeliness of on-the-spot tactical response,clarity of technical application purpose,coherence of throwing pot action structure,high efficiency of command and tactics arrangement,initiative of competition emotion control,pertinence of their own tactical design,firmness of competitive decisive confidence,clarity of field space-time perception,accuracy of opponent's tactical identification,comprehensiveness of judging competition situation,etc.
