A treadmill is an important tool in the equine analysis of gait, lameness, and hoof balance, as well as for the evaluation of horse rehabilitation or poor performance including dynamic endoscopy. Before all of these uses, horses have to be habituated to a treadmill locomotion. We used principal component analysis to evaluate the relationship between aspects of the horse’s temperament and emotional response, and progress in the behavioral habituation to a treadmill. Fourteen horses were tested, by the same familiar handler, using the novel object test, the handling test, and both positive and negative emotional response tests. Then, four stages of gradual habituation of the first work on a treadmill were conducted. Each time, the horse’s behavior was filmed. Data obtained from ethograms and heart rate measurements were tested. Four principal components were identified in examined horses: “Flightiness,” “Freeziness,” “Curiosity,” and “Timidity.” Flightiness was connected with nervousness, agitation by new objects, and easy excitability, and gradually decreased of features during habituation. Timidity was associated with a lack of courage and stress in new situations, and those features strongly increased when the treadmill was introduced. Freeziness and Curiosity features showed strong stability throughout the whole habituation. The results of this study provide evidence for a connection between temperament, emotional response, and habituation process in a horse.

习惯于跑步机期间的马行为，生理和情绪。

跑步机是马的步态，la行和蹄平衡的分析中的重要工具，也是评估马的康复能力或包括动态内窥镜检查在内的不良表现的重要工具。在所有这些用途之前，必须让马习惯跑步机的运动。我们使用主成分分析来评估马的气质和情绪反应之间的关系，以及对跑步机的行为习惯的进步。使用同一对象熟悉的处理程序，使用新颖的对象测试，操作测试以及正面和负面的情绪反应测试对14匹马进行了测试。然后，在跑步机上进行了第一个工作的逐渐适应的四个阶段。每次，都会记录马的行为。测试了从心电图和心率测量获得的数据。在检查的马匹中确定了四个主要成分：“轻快”，“自由度”，“好奇心”和“反感”。轻浮与神经质，新物体引起的躁动和容易的兴奋性有关，并且在习惯化过程中特征逐渐降低。胆怯与在新情况下缺乏勇气和压力有关，而这些特征在引入跑步机后大大增强。惯性和好奇心在整个习惯中都表现出很强的稳定性。这项研究的结果为马的气质，情绪反应和习惯化过程之间的联系提供了证据。并在习惯化过程中逐渐减少特征。胆怯与在新情况下缺乏勇气和压力有关，而当跑步机推出时，这些功能就大大增加了。惯性和好奇心在整个习惯中都表现出很强的稳定性。这项研究的结果为马的气质，情绪反应和习惯化过程之间的联系提供了证据。并在习惯化过程中逐渐减少特征。胆怯与在新情况下缺乏勇气和压力有关，而这些特征在引入跑步机后大大增强。惯性和好奇心在整个习惯中都表现出很强的稳定性。这项研究的结果为马的气质，情绪反应和习惯化过程之间的联系提供了证据。
