Abstract

In the last decades, previous research regarding interpersonal synergies formation has emerged under the Uncontrolled Manifold concept, identifying synergies formation based on a single combination of task elements. However, in social systems with redundant degrees of freedom, several combinations to stabilize a performance goal may be the most common picture. Thus, the main goal of this explorative study was to create a “portrait” of a set of task elements combinations (i.e., player’s positions and velocities) adopted to stabilize a performance goal (i.e., interpersonal distance) in expert badminton doubles, which is usually associated with synergies formation. The Uncontrolled Manifold concept was used for that purpose. Our results displayed that the created “portraits” did not display any pattern of interpersonal synergies. Moreover, for all the portraits there were combinations of task elements that had the primacy over the others. A primacy that changed with the rally length. For the shortest and for the longest rallies, the player’s velocity seemed to be more relevant to form interpersonal synergies, whereas for the middle length, both the player’s position and velocity were important for that purpose. Also, there were a decreasing of synergies strength with the increasing of the rally length.

摘要

在过去的几十年中，先前关于人际协同作用形成的研究出现在不受控制的流形概念下，基于任务元素的单一组合来识别协同作用的形成。然而，在具有冗余自由度的社会系统中，稳定绩效目标的几种组合可能是最常见的情况。因此，这项探索性研究的主要目标是创建一组任务元素组合（即球员的位置和速度）的“肖像”，以稳定专家羽毛球双打的表现目标（即人际距离），即通常与协同作用的形成有关。非受控歧管概念用于此目的。我们的结果表明，创建的“肖像”没有显示出任何人际协同作用的模式。而且，对于所有的肖像，都有优先于其他任务元素的组合。随着集会长度的变化而变化的首要地位。对于最短和最长的集会，球员的速度似乎与形成人际协同作用更相关，而对于中间长度，球员的位置和速度对于这个目的都很重要。此外，协同效应强度随着反弹长度的增加而下降。
