Pressure measurement devices in equine sports have primarily focused on tack (saddle pads and saddle fitting methods). However, saddle pressure devices may also be useful in evaluating the interaction and distribution of normal forces between the horse and rider, including rider position and riding technique. This study examined the validity, reliability, repeatability and possibilities of using a saddle pressure device to evaluate rider position. All measurements were performed using a standing horse. Validity was tested by calculating the correlation coefficient between measured normal force and the weight of the rider. Repeatability was tested by calculating intra-class correlation coefficients. The use of normal force measurements to evaluate horse-rider interaction was tested by adding a known weight to saddle or rider and collecting measurements with the rider sitting in four different positions. The device was found to be valid and reliable for force measurements when the measurement device was not replaced. The system could be used to determine the expected differences with added weight and in different rider positions. The normal force distribution measurement device proved to be a valid and reliable tool for studying the interaction between a rider and a static horse provided it is positioned carefully and consistently relative to both the horse and the saddle.
马术运动中的压力测量设备主要集中在马具（鞍垫和鞍具适配方法）上。然而，鞍具压力设备在评估马与骑手之间法向力的相互作用和分布方面也可能有用，包括骑手位置和骑行技术。本研究考察了使用鞍具压力设备评估骑手位置的有效性、可靠性、可重复性及可能性。所有测量均在站立的马匹上进行。通过计算测量的法向力与骑手体重之间的相关系数来测试有效性。通过计算组内相关系数来测试可重复性。通过在鞍具或骑手身上添加已知重量，并让骑手坐在四个不同位置收集测量数据，来测试使用法向力测量评估马与骑手相互作用的情况。当测量设备未更换时，发现该设备在力测量方面是有效且可靠的。该系统可用于确定添加重量和不同骑手位置时的预期差异。只要相对于马和鞍具仔细且一致地放置，法向力分布测量设备被证明是研究骑手与静态马匹之间相互作用的有效且可靠的工具。
