| With the vigorous development of national fitness and the appearance of three-player basketball in the Tokyo Olympic Games,the attention to the sport has been increased unprecedentedly and three-player basketball has become one of the most popular sports.Winning is the starting point of basketball competition,mastering and following the winning rule of three-player basketball,winning in competition is the goal of athletes and coaches.The winning factor in the three-player basketball game is not a certain factor,but the superposition of many factors influencing each other.ISM model can be used to transform the fuzzy relationship between the factors that affect the outcome of a three-player basketball match into a structural relationship model that is intuitive,easy to understand and logical to analyze.Therefore,the purpose of this paper is to find the key factors of winning three-player basketball games by using ISM model so as to increase the probability of winning games.This paper uses the method of literature,questionnaire,expert consultation,mathematical statistics and logical analysis to study the winning factors of three-player basketball based on ISM model.Through the establishment of ISM expert group,using Delphi method,experts through two rounds of screening,from seventy-six winning factors to the final determination of twenty-six three-player basketball winning factors.ISM model is used to establish the adjacency matrix by the relationship of elements,and then the reachable matrix is obtained by matrix operation,and then the hierarchy is divided,so that the complex system structure can clearly present the multi-level hierarchical structure form.Finally,the winning factors of three-player basketball can be divided into twelve surface factors,nine intermediate layer factors and five deep factors.On the basis of determining the surface factor,the middle factor and the deep factor,the ISM model is used to analyze the following conclusions: The winning factors of three-player basketball in order of importance,the deep factor is greater than the middle factor,the middle factor is greater than the surface factor;Surface factors are the direct factors that affect the winning of three-player basketball.The intermediate layer factor is the indirect factor that affects the winning of three-player basketball.The deep factor is the fundamental factor that affects the winning of three-player basketball.Put forward the following development countermeasures: pay attention to surface factors,improve the level of three-player basketball competition.It is necessary to pay attention to athletes’ psychological construction,athletes’ adaptability and coaches’ pre-competition preparation.Strengthen the middle layer factor and enhance the skill and tactics ability of three-player basketball.Consolidate the skill level of athletes and improve the tactical cooperation ability of athletes;Compacting the deep factors,cultivating the core competitiveness of three-player basketball.In particular,it is necessary to improve the athletes’ physical reserves and improve the coaching level of coaches. |
