This studyinvestigated the role the dyadic interaction variability plays in influencingdecision making on passing in the sport of futsal. Participants were 40 malestudents (Mage = 13.6 years, SD = 0.7) from physicaleducation classes of a Brazilian school. They were randomly divided into eightteams, which played four games of 24 minutesaccording to the rules of the under-14 category of thelocal Futsal Federation. From the games, a sample of 80 sequences of play involving passes were randomly selected, from themoment the ball carrier got possession of the ball until the moment he passedit. From the x and y coordinates of all outfield players’displacement, variability of running correlation, cross-correlation, centroid , andinterpersonal distance were calculated as measures of dyadic interaction.Results showed that the interaction of passer andreceiver dyads were more variable than the remaining dyads. Moreover, it wasverified that the passer dyad hadthe highest variability. The findings enabled us to conclude that, from the attackers’ point ofview, variability played a positive role. In addition, it appeared that thepasser sought to disrupt the interaction with his defender to perform a passmore than his teammates did to receive it. It appears that the skills ofpassing and receiving in the sport of futsal imply theability to vary.

二元交互的更高可变性在五人制足球传球的决策中发挥着积极作用

本研究调查了二元交互变化在影响五人制足球运动中的传球决策中所起的作用。参与者是来自巴西学校体育课的 40 名男学生（Mage = 13.6 岁，SD = 0.7）。他们被随机分成八支球队，按照当地五人制足球联合会14岁以下组别的规则进行四场24分钟的比赛。从比赛中，随机选择了 80 个涉及传球的比赛序列样本，从持球者获得球到他传球的那一刻。根据所有外场球员位移的x和y坐标，计算出跑动相关性、互相关性、质心和人际距离的变异性作为二元交互的度量。结果表明，传递者和接受者二元组的相互作用比其余二元组的变化更大。此外，已证实过路人二元组的变异性最高。这些发现使我们能够得出结论，从攻击者的角度来看，可变性起到了积极的作用。此外，传球手似乎比他的队友接球时更试图破坏与防守者的互动来执行传球。似乎五人制足球运动中的传球和接球技巧意味着变化的能力。看起来，传球手试图破坏与防守者的互动以执行传球，而不是他的队友接球。似乎五人制足球运动中的传球和接球技巧意味着变化的能力。看起来，传球手试图破坏与防守者的互动以执行传球，而不是他的队友接球。似乎五人制足球运动中的传球和接球技巧意味着变化的能力。
