To investigate the haematological, biochemical and metabolic response of greyhounds to sprint exercise, five greyhound dogs with previously placed carotid arterial catheters were sprinted over a distance of 400 m, chasing a lure. The time to complete the 400 m ranged from 25 to 27 seconds. Before exercise and at intervals for up to one hour after exercise, arterial blood samples were collected for haematology, serum biochemistry, plasma lactate and arterial blood gas measurements. Muscle samples for metabolite measurements were collected by needle biopsy of the vastus lateralis muscle. Red cell indices were increased for up to 20 minutes after exercise and there was a transient leucocytosis and neutrophilia. Serum biochemical changes reflected some fluid movement from the vascular compartment, there being increases in osmolality and total protein. Other changes included significant increases over resting control values for serum glucose, creatinine and potassium. The tension of oxygen in arterial blood was increased after exercise, while that of carbon dioxide fell, and there was a decrease in arterial pH. These changes were no longer significant by 30 minutes after exercise. The mean rectal temperature increased to 41 degrees C after exercise and remained elevated up to and including the 30 minutes after exercise measurement. No changes were found in muscle ATP or glycogen from before to after exercise. However, concentrations of muscle glucose and glucose-6-phosphate were increased immediately after exercise. Muscle and plasma lactate concentrations showed a similar time course for disappearance and after peaking at 27 mmol litre-1, five minutes after exercise, the plasma lactate returned towards pre-exercise values by 30 minutes after exercise.
