Aerobic capacity and fitness was studied in three different horse breeds (Andalusian, Arabian and Anglo-Arabian) using a four-level exercise test of gradually increasing intensity (15, 20, 25 and 30 km/h). The lactate concentration at the first three exercise levels was significantly lower for Arabian and Anglo-Arabian horses relative to Andalusian horses, but similar for the three breeds at the last level. Arabian and Anglo-Arabian horses reached a higher rate than Andalusian horses at plasma lactate concentration of 2 mmol/l (VLA2) and 4 mmol/l (VLA4). Andalusian horses exhibited a significantly lower heart rate at rest than the other two breeds, but the differences virtually disappeared at 15 km/h. At 20 km/h, Andalusian horses reached a higher heart rate than Arabian and Anglo-Arabian horses; at 25 km/h, however, their heart rate only exceeded that of Anglo-Arabian horses. Finally, no significant differences between breeds were observed at 30 km/h. No differences between breeds as regards heart rate were found if this was expressed as a function of lactate plasma concentrations of 2 mmol/l (HRLA2) and 4 mmol/l (HRLA4). At a heart rate of 150 (VHR150) and 200 beta/min (VHR200), Andalusian horses achieved the lowest speeds.
利用强度逐渐增加的四级运动测试（15、20、25和30公里/小时），对三种不同马种（安达卢西亚马、阿拉伯马和英阿拉伯马）的有氧能力和体能进行了研究。在前三个运动水平下，阿拉伯马和英阿拉伯马的乳酸浓度相对于安达卢西亚马显著更低，但在最后一个水平下，三个马种的乳酸浓度相似。在血浆乳酸浓度为2毫摩尔/升（VLA2）和4毫摩尔/升（VLA4）时，阿拉伯马和英阿拉伯马达到的速率高于安达卢西亚马。安达卢西亚马在静息时的心率显著低于其他两个马种，但在15公里/小时时，这种差异几乎消失。在20公里/小时时，安达卢西亚马的心率高于阿拉伯马和英阿拉伯马；然而，在25公里/小时时，它们的心率仅超过英阿拉伯马。最后，在30公里/小时时未观察到马种之间的显著差异。如果将心率表示为血浆乳酸浓度为2毫摩尔/升（HRLA2）和4毫摩尔/升（HRLA4）的函数，则未发现马种之间在心率方面存在差异。在心率为150（VHR150）和200次/分钟（VHR200）时，安达卢西亚马达到的速度最低。
