The changes of cortisol, red blood cells (RBC), hemoglobin (Hb), hematocrit (Hct), heart rate (HR), respiratory rate (RR) and rectal temperature (RT) were evaluated after a reining training session in eight Quarter Horses. All parameters were measured before exercise (T0), immediately after exercise (T1), 1 h after exercise (T2), 2 h after exercise (T3) and 24 h after exercise (T4). One-way analysis of variance (ANOVA) for repeated measures, followed Bonferroni's post hoc test, showed a significant effect of the reining training session (P < 0.0001) on cortisol, RBC, Hb, Hct, HR, RR and RT. Simple linear regression analysis showed the positive correlation (P < 0.05) between cortisol changes and variations of studied parameters in T1, T3 and T4. Exercise-induced cortisol concentrations reflect the physiological response of reining training, suggesting that the changes observed are useful to assess the performance in reining horses and their reining training adaptability.
对8匹夸特马进行驯马训练后，评估了皮质醇、红细胞（RBC）、血红蛋白（Hb）、血细胞比容（Hct）、心率（HR）、呼吸频率（RR）和直肠温度（RT）的变化。在运动前（T0）、运动后即刻（T1）、运动后1小时（T2）、运动后2小时（T3）和运动后24小时（T4）测量所有参数。重复测量的单向方差分析（ANOVA），随后进行Bonferroni事后检验，结果显示驯马训练对皮质醇、RBC、Hb、Hct、HR、RR和RT有显著影响（P < 0.0001）。简单线性回归分析表明，在T1、T3和T4时，皮质醇变化与所研究参数的变化之间存在正相关（P < 0.05）。运动诱导的皮质醇浓度反映了驯马训练的生理反应，表明观察到的变化有助于评估驯马的表现及其对驯马训练的适应性。
