During training, in 10 trotters, blood samples from the vena jugularis were taken before and after a heat with 80% of maximum capability as well as in the recovery period. Lactic acid concentration and pH-value, haematocrit and haemoglobin content, as well as protein concentration and osmolality were measured. With the exception of protein concentration, the time course of the values during the recovery could be described by simple mathematical models (biexponential or exponential equations). Only in the case of blood lactate concentration, the basal value was not yet achieved 120 min after the end of exercise. In the case of the other examined parameters, the homeostasis was restored earlier. Therefore, it seems to be recommendable when performing tests with preliminary heats and finals on the same day to stick to a break of at least 2 h between two races.
在训练期间，对10只蹄子进行了实验，在以最大能力的80%进行加热前后以及恢复期，从颈静脉采集血样。测量了乳酸浓度和pH值、血细胞比容和血红蛋白含量，以及蛋白质浓度和渗透压。除蛋白质浓度外，恢复期间各项指标的时间进程可用简单的数学模型（双指数或指数方程）来描述。仅血乳酸浓度在运动结束120分钟后仍未达到基础值。对于其他检测参数，内环境稳态恢复得更早。因此，在同一天进行预赛和决赛测试时，两场比赛之间至少间隔2小时似乎是可取的。
