Here, we report an investigation of the patterned movement behavior of players for a specific sub-phase of the game of futsal, namely when the goalkeeper for the attacking team is substituted with an extra outfield player. The movement trajectories of the ball and players were recorded in both lateral and longitudinal directions and investigated using relative phase analysis. Some differences in phase relations between different playing dyads were noted, indicating specificity of phase attractions, or otherwise, for certain players. In general terms, the defenders demonstrated strong in-phase attractions with the ball and with each other, whereas weaker phase attractions, indicated by increased relative phase variability, were observed for the attackers and ball, as well as between attackers themselves. These results demonstrate different coordination dynamics for the defending and attacking dyads, from which we interpret evidence for different playing sub-systems consistent with different team objectives linked together in an overarching game structure. In keeping with dynamical systems theory for complex systems, we view this sub-phase of futsal as being characterized by coordinated behavior patterns that emerge as a result of self-organizing processes. These dynamic patterns are generated within functional constraints, with players and teams exerting mutual influence on each other.
在这里，我们报告了对五人制足球比赛中守门员被替换为额外的场外球员这一特定子阶段的球员有模式化运动行为的调查。球和球员的运动轨迹分别在横向和纵向进行了记录，并使用相对相位分析进行了研究。注意到不同比赛二人组之间的相位关系存在一些差异，这表明某些球员之间存在相位吸引的特异性，或者其他情况。一般来说，防守球员与球和彼此之间表现出强烈的同相位吸引力，而对于攻击者和球，以及攻击者之间，则观察到较弱的相位吸引力，这表明相对相位变化性增加。这些结果表明防守和攻击二人组之间存在不同的协调动力学，我们从中推断出与不同的团队目标相关联的不同比赛子系统的证据，这些目标都包含在一个总体的比赛结构中。根据复杂系统的动力系统理论，我们将这个五人制足球子阶段视为具有协调行为模式的特征，这些模式是自组织过程的结果。这些动态模式是在功能约束下产生的，球员和球队相互影响。
