The aim of this study was to investigate the behavioural response of horses to rein contact and the movement of the riders' hands through analysis of data from horses ridden at two different head and neck positions. It was hypothesised that the riders' hand movements and rein tension would generate behavioural responses from horses and that these responses would be more marked when horses were ridden 'on the bit' than when unrestrained. Data were collected from seven dressage horse/rider combinations at sitting trot on a high speed treadmill. Kinematics were recorded using a 12-camera, infrared-based opto-electronic system. Three horses wore a rein tension meter. Behavioural registrations were made from video. Behavioural responses included lip movement, mouth movement, open mouth, change in ear position, head tilt and tail movement. Mouth movements were associated with the suspension phase of the trot. Head and neck position was non-significant in the final models, while rein tension and the distance between the rider's hand and the horse's mouth were related to mouth movements. Interactions between horses and riders are complex and highly variable.
本研究的目的是通过分析在两种不同头部和颈部位置骑行的马匹数据，来调查马匹对缰绳接触的行为反应以及骑手手部的动作。研究假设骑手的手部动作和缰绳张力会引发马匹的行为反应，并且当马匹“受衔”骑行时，这些反应会比无约束时更为明显。在高速跑步机上以坐姿快步收集了七对盛装舞步马/骑手组合的数据。使用基于红外的12摄像头光电系统记录运动学数据。三匹马佩戴了缰绳张力计。通过视频进行行为记录。行为反应包括唇部动作、嘴部动作、张嘴、耳部位置变化、头部倾斜和尾巴动作。嘴部动作与快步的悬空阶段相关。在最终模型中，头部和颈部位置不显著，而缰绳张力以及骑手手部与马嘴之间的距离与嘴部动作有关。马匹与骑手之间的互动复杂且高度可变。
