It is well known that athletes undergo simultaneous potentiation of hemostatic pathways that affects both coagulation and fibrinolytic activity. Increased flbrinolytic activity appears to counterbalance exercise-induced increases in clotting. However, data available on horses are not unequivocal. On account of this, we investigated the effect of an endurance competition on some clotting (PT, aPTT, TT and fibrinogen) and haematological (RBC, WBC, Hb, Hct, MCV, MCH, MCHC, PLT) parameters in 6 horses during an official long distance run. Blood samples were collected from all the horses: at rest, immediately after the run, 30′ and 60′ after the run. Only TT showed statistically significant differences between the different experimental conditions, being significantly prolonged immediately after the run, 30′ and 60′ after the run compared to rest. The remaining clotting parameters (aPTT, PT, fibrinogen) did not demonstrate statistical significance. This could be due to the type of exercise that implies a submaximal effort for horses.

Abstract

It is well known that athletes undergo simultaneous potentiation of hemostatic pathways that affects both coagulation and fibrinolytic activity. Increased flbrinolytic activity appears to counterbalance exercise-induced increases in clotting. However, data available on horses are not unequivocal. On account of this, we investigated the effect of an endurance competition on some clotting (PT, aPTT, TT and fibrinogen) and haematological (RBC, WBC, Hb, Hct, MCV, MCH, MCHC, PLT) parameters in 6 horses during an official long distance run. Blood samples were collected from all the horses: at rest, immediately after the run, 30′ and 60′ after the run. Only TT showed statistically significant differences between the different experimental conditions, being significantly prolonged immediately after the run, 30′ and 60′ after the run compared to rest. The remaining clotting parameters (aPTT, PT, fibrinogen) did not demonstrate statistical significance. This could be due to the type of exercise that implies a submaximal effort for horses.
