Research On The Evaluation Of Offensive And Defensive Abilities Of CBA Domestic Small Forward Players Based On Structural Equations

In order to further improve the evaluation method of attacking and defending ability of small forwards and improve the competitive strength of domestic small forwards.This paper takes the evaluation of the offensive and defensive ability of domestic small forwards in CBA as the research object,selects the domestic small forwards in the CBA playoffs of 2017-2018,2018-2019 and 2019-2020 as the observation object,and takes the offensive and defensive index data of some domestic small forwards in the playoffs as the statistical object.By applying the method of documentary,interview,questionnaire investigation,comparative analysis and method of GM(1,1)model and confirmatory factor analysis,the three season playoff small forward players in attack and defense ability through the contrast analysis of defensive ability evaluation and establish the first-order CFA small forward theoretical model,using confirmatory factor analysis to verify the optimized,it is concluded that important degree of each evaluation index.It can not only provide theoretical reference for the evaluation of domestic small forwards' offensive and defensive ability,but also provide reference for the improvement of Chinese small forwards' offensive and defensive ability in practice.Through the research,the following conclusions are drawn:1.In the past three seasons,the height of Chinese small forward players showed a trend of gradual rise,while the weight and Kleto index showed a trend of gradual decline,but there was no obvious difference in general.2.In the past three seasons,the offensive ability of domestic small forwards has been on the rise,but there are still shortcomings in the two point ability,free throw ability and three point ability,and the control of assists,frontcourt rebounds and mistakes should be gradually brought into the central position.The defensive ability of small forwards in China is also gradually improving.No matter in the scramble for defensive rebounds,or in the data of steals and blocks,the defensive ability of small forwards in China is showing a better and better trend.The physical quality of small forwards in China is improving,but they still need to control the number of fouls more accurately and learn to use the game rules more reasonably.3.Sixteen micro indicators reveal the internal strength of small forwards' offensive and defensive capabilities.After verification,the first-order CFA theoretical model of domestic small forwards' offensive and defensive capabilities in CBA has very good verification results.4.The importance degree of each micro index in attacking and defending ability of domestic small forwards is from large to small two-pointer attempts > two-pointer score a hit > free throws made > free throw percentage > defensive rebound > three-pointer hit rate > three-pointer score a hit > assist > steal > muff > block shot > offensive rebound > free throw attempts >three-pointer attempts > defensive foul > two-pointer percentage.
