Temperament has not been taken into account in previous studies evaluating the stress response to exercise in horses. The aim of the present study was to investigate the cortisol response in Thoroughbred racehorses to a single exercise bout, and to analyse the results based on the basic personality of the horse examined. Twenty healthy Thoroughbred horses were selected for the study based on a 25-item rating questionnaire survey used for characterising equine temperament. Eight temperamental and twelve calm horses took part in the experiment. The horses trotted as a warm-up activity, and then galloped on a rounded sand track. Blood sampling was conducted four times for each horse. Horses with a more excitable temperament showed a higher cortisol response to the test (P = 0.036). In conclusion, cortisol levels in response to a mild intensive exercise can be affected by temperament in horses. Serum cortisol may be a relevant marker to quantify individual temperamental differences in racehorses.
在以往评估马匹运动应激反应的研究中，气质因素未被考虑在内。本研究的目的是调查纯种赛马对单次运动 bout 的皮质醇反应，并根据所检查马匹的基本性格分析结果。基于一份用于描述马气质的 25 项评分问卷调查，选择了 20 匹健康的纯种马进行研究。8 匹易激动的马和 12 匹安静的马参与了实验。马匹先小跑作为热身活动，然后在圆形沙地跑道上疾驰。每匹马进行了 4 次采血。气质更易激动的马对测试表现出更高的皮质醇反应（P = 0.036）。总之，马匹对轻度高强度运动的皮质醇水平可能会受到气质的影响。血清皮质醇可能是量化赛马个体气质差异的一个相关标志物。
