In riding, most biomechanical studies have focused on the description of the horse locomotion in unridden condition. In this study, we draw the prospect of how the basic principles established in inter-personal coordination by the theory of Coordination Dynamics may provide a conceptual and methodological framework for understanding the horse-rider coupling. The recent development of mobile technologies allows combined horse and rider recordings during long lasting natural events such as endurance races. Six international horse-rider dyads were thus recorded during a 120 km race by using two tri-axial accelerometers placed on the horses and riders, respectively. The analysis concentrated on their combined vertical displacements. The obtained shapes and angles of Lissajous plots together with values of relative phase between horse and rider displacements at lower reversal point allowed us to characterize four coordination patterns, reflecting the use of two riding techniques per horse's gait (trot and canter). The present study shows that the concepts, methods and tools of self-organizing dynamic system approach offer new directions for understanding horse-rider coordination. The identification of the horse-rider coupling patterns constitutes a firm basis to further study the coalition of multiple constraints that determine their emergence and their dynamics in endurance race.
在骑马运动中，大多数生物力学研究都集中在描述无人骑乘状态下的马的运动。在这项研究中，我们探讨了人际协调理论中的协调动力学所确立的基本原则如何为理解马和骑手的耦合提供一个概念和方法框架。移动技术的最新发展使得在诸如耐力赛等长时间自然事件中可以对马和骑手进行联合记录。因此，通过在马和骑手身上分别放置两个三轴加速度计，对六个国际骑手组合在 120 公里比赛中进行了记录。分析集中在他们的联合垂直位移上。获得的李萨如图形的形状和角度以及骑手在较低反转点处的位移的相对相位值使我们能够描述四种协调模式，反映了每种马的步态（快步和跑步）使用两种骑行技术。本研究表明，自组织动态系统方法的概念、方法和工具为理解马和骑手的协调提供了新的方向。识别马和骑手的耦合模式为进一步研究决定它们在耐力赛中出现和动态的多个约束的联合提供了坚实的基础。
