摘要
本文以巴黎奥运会男子篮球参赛队伍的攻防竞技能力为研究对象,通过Q型聚类、TOPSIS和灰色关联等方法,对各参赛队伍的攻防指标进行分析.结果显示:(1)通过Q型聚类分析,将巴黎奥运会男篮参赛队伍分为4个类别:美国队(USA)是第一类别,法国队(FRA)、德国队(GER)、加拿大队(CAN)、希腊队(GRE)和西班牙队(ESP)为第二类别,塞尔维亚队(SRB)、澳大利亚队(AUS)、巴西队(BRA)、南苏丹队(SSD)和波多黎各队(PUR)为第三类别,JPN为第四类别."聚类等级"与"实际排名"之间存在显著的正相关关系(r=0.632,P=0.027).(2)通过TOPSIS分析,各参赛队伍攻防值排序依次为USA、SRB、SSD、AUS、BRA、CAN、ESP、JPN、FRA、PUR、GER、GRE,攻防Ci值秩次与实际排名之间不存在显著的相关关系(r=0.364,P=0.245).(3)影响巴黎奥运会男篮比赛得失分的因素,依据关联度的排序,依次为FGM、OR、FG％、3FG％、TOT、2FGM、AS、FGA、FT％、LP、2FG％、PF、ST、2FGA、3FGM、3FGA、DR、TO、FTA、FTM、FBP、BS,其中主要影响因素排序的依次为 FGM、OR、FG％、3FG％、2FGM、AS、FGA、FT％、LP、2FG％、PF 和 ST.建议:制订专项技术训练计划;强化团队协作与实战演练;制订精细化的三分球战术;建立定期评估与反馈机制;加强对手分析与针对性训练.
Abstract
This study examines the offensive and defensive capabilities of participating teams in the men's basketball games at the 2024 Paris Olympics.Through Q-type cluster analysis,TOPSIS analysis,and grey relational analysis,the study analyzes the performance indicators of each team.The results demonstrate that:(ⅰ)Based on Q-type cluster analysis,the participating teams in the men's basketball events at the Paris Olympics can be classified into four categories:Team USA as the first category,teams of FRA,GER,CAN,GRE,and ESP as the second category,teams of SRB,AUS,BRA,SSD,and team PUR as the third category,and team JPN as the fourth category.A significant positive correlation exists between"cluster ranks"and"actual ranks"(r=0.632,P=0.027*).(ⅱ)According to TOPSIS analysis,the ranking of offensive and defensive values for each team is as follows:USA,SRB,SSD,AUS,BRA,CAN,ESP,JPN,FRA,PUR,GER,and GRE.There is no significant correlation between the Civalues rank and the actual ranks(r=0.364,P=0.245).(ⅲ)The factors influencing points gained and lost in the men's basketball competition at the Paris Olympics,based on their correlation,are ranked as follows:FGM,OR,FG％,3FG％,TOT,2FGM,AS,FGA,FT％,LP,2FG％,PF,ST,2FGA,3FGM,3FGA,DR,TO,FTA,FTM,FBP,BS.The primary influencing factors are FGM,OR,FG％,3FG％,2FGM,AS,FGA,FT％,LP,2FG％,PF,and ST.The study puts forward suggestions that include developing specialized technical training plans,reinforcing teamwork and practical exercises,devising precise three-point shooting tactics,establishing regular evaluation and feedback mechanisms,and enhancing opponent analysis and targeted training.
