Research On The Construction Of The Evaluation System Of Personal Offensive Ability Of Domestic Centers In CBA

In order to further improve the evaluation of the attacking ability of the center,improve the competitive strength of the domestic center.Taking the construction of the evaluation system of the individual offensive ability of the domestic centers in the CBA as the research object,the domestic centers in the 2018-2019 season of the CBA league were selected as the observation object.By literature data method,questionnaire survey method,interview method,video observation,mathematical statistics,confirmatory factor analysis,experts to check after the primary index through normal distribution test,single factor analysis of variance face a significant difference indexes evaluation theory model is set up,using confirmatory factor analysis to verify the optimized basketball center individual attack ability evaluation system is constructed.It can not only provide a theoretical reference for the evaluation of the individual offensive ability of the Chinese men's basketball center players,but also provide a practical reference for the improvement of the offensive ability of the Chinese men's basketball center players.Through the research,the following conclusions are drawn:1.The evaluation index of the center's individual offensive ability is composed of four macro indexes: "scoring ability","ball control ability","ability to grab and receive the ball" and "ability to grab and attack the rebound".Among them,"scoring ability" is composed of 6 micro indexes,such as short jump shot,low post finish shot,recovery shot,central jump shot,long jump shot and free throw shot."Ball control ability" is composed of five micro-indexes: bottom Angle 0-30 degree holding breakthrough,top arc 60-60 degree holding breakthrough,bottom Angle 0-30 degree dribbling breakthrough,top arc 60-60 degree holding breakthrough,assist and create opportunities."Ability to catch the ball in position" consists of 6 micro-indexes:back-body position,side-body position,back-hanging position,strong side downstroke,from the weak side to the strong side,and under the top of the arc.The "ability to grab offensive rebounding" consists of three micro-indexes: two hands,one hand and one hand.2.There is a large coefficient of co-variation between the four macro indicators of the center's "scoring ability","ball control ability","position grabbing and receiving ability" and "offensive rebounding ability".The macro indicators of the center are closely related to each other,and the development of each ability will have an impact on other abilities.3.Reveal the internal strength of the center's individual offensive ability by using 4 macro indicators and 20 micro indicators.The path coefficients of "scoring ability","ball control ability","ability to grab and catch the ball" and "ability to grab and rebound the ball" on individual offensive ability were 0.89,0.40,0.46 and 0.29,respectively.The microcosmicloading coefficients of "scoring ability" are 0.14,0.34,0.43,0.20,0.20 and 0.39,respectively.The microcosmic load coefficients of "ball control capacity" are 0.32,0.59,0.24,0.48 and 0.65,respectively.The load coefficients of the micro indexes of "position grab and catch ability" are0.47,0.78,0.60,0.33,0.68 and 0.48.The microcosmic load coefficients of "attacking rebound" are 0.55,0.94 and 0.68.4.The construction and scoring of the evaluation system for the individual offensive ability of centers in CBA,as well as the establishment of the evaluation criteria,well reflect the internal characteristics of the offensive ability of centers,and at the same time,demonstrate a high degree of reliability and scientificity.
