基于灰色关联分析辽宁队实时情境下的投篮效率

An Analysis of Real-Time Shooting Efficiency of Liaoning Team Based on Grey Correlation

2021-2022CBA赛季,辽宁队时隔四年再度夺得总冠军,其实力毋庸置疑。为探究辽宁队不同实时情境下的投篮效率特征及优劣势,本文采用文献资料法、录像观察法、数理统计法等研究方法对辽宁队季后赛的9场比赛共761次投篮数据进行整理分析。结果显示:辽宁队是一支具有内线冲击强、外线投射准、快速进攻高效等特点的球队。其不同实时情境下投篮效率与投篮效率理想值(即100%命中率)的关联性相比,结果为:近距离、1-2次传球、无防守压力情境下投篮效率高,16<t≤24、中远距离、≥5次传球情境下投篮效率低。

In the 2021-2022 CBA season, Liaoning team won the championship title again after four years. The strength of Liaoning team is beyond doubt. In order to explore the characteristics, advantages and disadvantages of Liaoning team’s real-time shooting efficiency, this study used the methods of literature review, video observation and mathematical statistics to sort out the shooting data of 761 shots in nine playoff matches of Liaoning team. The results revealed that Liaoning team has strong impact force at the inside, accurate outside shooting, and efficient fast break. The correlation between the team’s real-time shooting efficiency and the ideal shooting efficiency value(i.e., 100% field goal percentage, FG%)showed that its shooting efficiency is(1)high in short-range shots, or after 1-2 passes, or without defensive pressure and(2)low when 16 < t ≤ 24, in mid-and long-range shots, or after ≥ 5 passes.
