论文摘要

在排球比赛中,我们将集会定义为一系列事件,因为球被送达,直到球场上的两支球队之一得分为止。在此过程中,运动员响应物理和信息限制而发展,跨越了几个时空量表,并与环境共同适应。为了研究该系统中复杂性的出现,我们进行了一项研究,重点是:数据收集,数据分析和建模。首先,我们从20个高级专业排球游戏中收集了数据。然后,我们从数据驱动的分析中进行了数据驱动的分析,我们确定了我们用来为游戏动力学定义的简约随机模型的基本见解。在这些基础上,我们表明可以给出封闭形式的表达式,因为玩家仅使用两个随机变量在集会中执行N命中率的概率。我们的结果完全同意经验观察,并代表了理解团队运动竞争复杂性和动态的新进步。

In volleyball games, we define a rally as the succession of events observed since the ball is served until one of the two teams on the court scores the point. In this process, athletes evolve in response to physical and information constraints, spanning several spatiotemporal scales and interplaying co-adaptively with the environment. Aiming to study the emergence of complexity in this system, we carried out a study focused on three steps: data collection, data analysis, and modeling. First, we collected data from 20 high-level professional volleyball games. Then we conducted a data-driven analysis from where we identified fundamental insights that we used to define a parsimonious stochastic model for the dynamics of the game. On these bases, we show that it is possible to give a closed-form expression for the probability that the players perform n hits in a rally using only two stochastic variables. Our results fully agree with the empirical observations and represent a new advance in the comprehension of team-sports competition complexity and dynamics.
