Plasma biochemical values were measured in 14 horses, before a 160 km endurance ride, immediately after 85 km, immediately after 160 km, after 30 min recovery period and the day after the ride. For statistical analysis, a group of 7 horses that completed the ride at a mean speed of 234 metres per min (m/min) (Fast Group) was compared with 7 horses that completed the ride at a mean speed of 144 m/min (Slow Group). Estimations were made of sodium, potassium, chloride, bicarbonate, glucose, creatinine, urea, bilirubin, iron, total protein, albumin, calcium, phosphate, cholesterol, alkaline phosphate, gammaglutamyl transferase, lactate dehydrogenase, alpha hydroxybutyrate dehydrogenase, asparate amino transferase, alanine amino transferase, cortisol and insulin. Disturbances in biochemical values associated with endurance exercise reflected dehydration, hepatic dysfunction, reduced renal function and muscle damage. The faster the speed of exercise, the greater was the stress as reflected by cortisol values. The Fast Group of horses also demonstrated lower glucose and higher CK and LD values than the Slow Group of horses. However, biochemical values the day after the ride were similar to values before the ride.
在14匹马中测量了血浆生化值，分别是在160公里耐力骑行前、85公里后即刻、160公里后即刻、30分钟恢复期后以及骑行后第二天。为了进行统计分析，将一组以平均每分钟234米（m/min）的速度完成骑行的7匹马（快速组）与以平均每分钟144米的速度完成骑行的7匹马（慢速组）进行比较。对钠、钾、氯、碳酸氢盐、葡萄糖、肌酐、尿素、胆红素、铁、总蛋白、白蛋白、钙、磷酸盐、胆固醇、碱性磷酸酶、γ-谷氨酰转移酶、乳酸脱氢酶、α-羟丁酸脱氢酶、天冬氨酸氨基转移酶、丙氨酸氨基转移酶、皮质醇和胰岛素进行了测定。与耐力运动相关的生化值紊乱反映了脱水、肝功能障碍、肾功能降低和肌肉损伤。运动速度越快，皮质醇值所反映的应激就越大。快速组马匹的葡萄糖水平也低于慢速组，肌酸激酶（CK）和乳酸脱氢酶（LD）值则高于慢速组。然而，骑行后第二天的生化值与骑行前相似。
