Beschreibungen/Notizen

• Eighteen blesbok were subjected to forced exercise for distances varying from, 2-10+ km. Estimations were made on arterial samples taken from the femoral artery within 5 minutes of capture. The analysis showed increased blood acidity. There was a marked reduction in plasma bicarbonate with a negative base excess. The most notable fall in pH and the strongest indication of acid production were found in those animals chased rapidly over a short distance. Animals run over a longer distance showed a less marked acidosis. Acidosis seemed to be associated largely with the metabolic phase, compensation to respiratory acidosis occurring either during or immediately after the exercise. Recovery of normal levels of blood gases was rapid, especially with regard to Oxygen partial pressure which tended to return to normal within half an hour.
