功能内稳态理论视角下篮球得分频率变异系数与球队实力的相关性

Correlation Between Variation Coefficient of Scoring Frequency and Team Strength in Basketball from Perspective of Functional Homeostasis Theory

基于功能内稳态理论,运用文献资料法、专家访谈法、逻辑推理法初步提出核心球员得分频率的变异系数(CV)可能是精细表征篮球运动中球队综合实力强弱的方法这一观点,并通过sigma-liu算法对美国国家篮球协会2013-2018五个赛季12300场比赛的相关数据予以相关验证。研究表明:核心球员得分频率CV可以表征所在球队的实力,且得分频率CV越小,实力越强;得分频率CV越大,实力越弱。

Based on the function-specific homeostasis theory, this paper adopted literature study, expert interview and logic inference to propose the idea that the coefficient of variation(CV) might finely represent the team’s comprehensive strength in basketball, and verified the relevant data of 12300 games in the five seasons from 2013 to 2018 by sigma-liu algorithm. The results showed that the CV of the score frequency of the core player could represent the strength of the team, and the smaller the score frequency CV, the stronger the strength, and the greater the score frequency CV, the weaker the strength.
