Physiological parameters and evaluation of the upper and lower respiratory airways in french standardbred trotters during a standardised exercise on a treadmill

Paramètres physiologiques et évaluation des voies respiratoires supérieures et inférieures chez des trotteurs français au cours d'un exercice standardisé sur tapis roulant

Résumé

This study was carried out in 115 horses between 2 and 9 years old, ready to race or actively racing. The animals were divided into two groups: 23 horses with good racing results representing the control group, and 92 horses with poor racing results. The standardised exercise test started with a 10 min warm-up at a slow trot, followed by 3 periods of exercise of 3 min each. After the three periods, the horse was stopped on the treadmill for 1 min, the endoscope was inserted, and the horse performed a fourth period at maximal speed. The heart rate (HR) was measured throughout the test and blood was collected via a catheter inserted in the transverse facial artery during the last 10 seconds of each period. One hour after the exercise, a broncho-alveolar lavage (BAL) was performed. The results of this study (HR, blood lactate, PaO2) suggest that there is a significant difference in the metabolic response to exercise between poor performers and good performers. The results of the endoscopy during exercise and post-exercise BAL were used to divide poor performers into 4 groups, based on the localisation of the problem: upper respiratory airway (URA) disease, lower respiratory airway (LRA) disease, URA and LRA disease, and other diseases. These tests were also used to evaluate the metabolic response to exercise in the different situations. Post-exercise BAL may provide important information, even in horses with evidence of upper respiratory disease.
