[en] Seven sport horses were investigated to compare physiological and pharmacological stresses on the plasma glucocorticosteroid levels.
<br />Venous blond was sampled and analysed for cortisol concentrations before and after each type of stress. The physiological stress was induced by the completion of a cross-country and the phar¬macological one, by an intravenous ACTH administration (200 µg) in the came horses, one week after the course.
<br />Both exercise and ACTH injection induced a highly significant cortisol increase of 79 ± 0.10 %, and 160 ± 0.18 %, respectively. The relative plasma cortisol increases due to exercise on the nue hand, and due to ACTH administration on the other hand, were correlated with a coefficient of 0.82. It was concluded that the plasma cortisol increase induced by a standardised pharmacological stress could be used in order to predict the exercise-induced stress response.
