As previous studies have suggested that bimanual coordination is important for slacklining, the authors questioned whether this important skill plays a role in the performance of a fundamental task of slacklining. To address this question, the authors compared single-leg standing on the slackline between novices and experts in terms of bimanual coordination dynamics within a dynamical systems framework using relative phase and recurrence quantification analysis measures. Five novices and five experts participated in the experiment. Participants were required to perform single-leg standing on a slackline. To collect motion data while slacklining, the authors used a 3D motion capture system and obtained time series data on the wrist position of both hands. The authors compared bimanual coordination dynamics between novices and experts. Although this preliminary study was limited in its sample size, the results suggest that experts tend to show a more antiphase coordination pattern than novices do and that they can more sustainably coordinate their hands compared with novices in terms of temporal structure in diagonal-related recurrence measures (i.e., maxline, mean line, and percentage determinism).

由于之前的研究表明双手协调对于松紧带很重要，因此作者质疑这项重要技能是否在执行松紧带的基本任务中发挥作用。为了解决这个问题，作者使用相对相位和递归量化分析措施，在动力系统框架内的双手协调动力学方面比较了新手和专家之间的单腿站立。5名新手和5名专家参加了实验。参与者被要求在松弛的绳索上进行单腿站立。为了收集松弛时的运动数据，作者使用了 3D 运动捕捉系统，并获得了双手手腕位置的时间序列数据。作者比较了新手和专家之间的双手协调动态。
