Abstract

Purpose: In many sports situations, two or more players need to coordinate their actions to make sure that one of them intercepts a ball or opponent. We considered how two soccer players head back a thrown ball. Two accounts for the joint decision making by both players were considered. These two accounts not only differ in their theoretical basis but also have vastly different implications for training practice. In a first account, players know their areas of responsibility for interception, and combine this with their prediction of the ball's landing location. In a second account, the coordination emerges from the unfolding dynamics of the system of informationally connected players and ball. According to this second account, especially for balls aimed in between the two players, both of the players may start moving and one player sees that the ball will be interceptable for the other player, and subsequently yields the interception. Methods: We instrumented soccer players and the ball with Kinexon sensors and had pairs of players head back the thrown ball. Results: In line with the second account, the results showed a fair number of instances where the player who intercepted the ball had to move the longest distance. Furthermore, considerable movement by both players was not an exception. Conclusion: The results can be taken as a first step towards an understanding of joint coordination as an emergent phenomenon.

足球头球的紧急协调:两名球员和一个球。
目的:在许多运动场合,两个或更多的球员需要协调他们的行动,以确保其中一个拦截球或对手。我们考虑了两名足球运动员是如何头球回传的。考虑了双方共同决策的两个原因。这两种说法不仅理论基础不同,而且对培训实践的影响也大不相同。在第一种解释中,玩家知道自己负责拦截的区域,并将此与他们对球着陆位置的预测结合起来。在第二种解释中,协调来自于信息连接的球员和球的系统的展开动态。根据第二种说法,特别是在两名球员之间的球,两名球员都可能开始移动,其中一名球员看到另一名球员可以拦截球,随后就会拦截球。方法:我们用Kinexon传感器对足球运动员和球进行仪器测量,并让两名球员在抛出的球后头回。结果:与第二种说法一致,结果显示,在相当多的情况下,拦截球的球员必须移动最远的距离。此外,两名球员的大量移动也不例外。结论:研究结果可作为理解关节协调是一种突现现象的第一步。

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
