Five healthy, fit Standardbreds (mean +/- SEM, 490.4 +/- 15.0 kg, 4.0 +/- 0.5 years) were studied during a standardized test carried out on a treadmill. The test consisted of an 8-minute warm-up and a 9-minute exercise period (1 minute at 1.7, 4, 7, 8, 9, and 10 m/s; 2 minutes at 4 m/s; and a 1-minute walk at a 6% slope). Respiratory airflow, tidal volume (V(T)), and respiratory frequency (f) were continuously recorded, using 2 ultrasonic pneumotachographs connected to a face mask and mass spectrometer. Oxygen uptake, carbon dioxide output, and expired minute volume (V(E)) were obtained on a breath by breath basis. Arterial blood was tested at the end of each step for O2 and CO2 partial pressures. Heart rate was continuously recorded, using a heart rate recording system. Stride frequency was measured at each step, and the stride frequency-to-f ratio was calculated. Venous blood was tested for plasma lactate concentration be fore and 2 minutes after completion of the test. Some horses had a locomotion-respiration coupling (LRC), but this coupling was occasional and intermittent. The f was lower and V(T) was higher than values reported for thoroughbreds working under similar experimental conditions. Nevertheless, maximal V(E) did not overshoot maximal V(E) reported in Thoroughbreds. All horses were hypoxemic and hypercapnic, but there was wide variability between subjects. The horses with the highest oxygen uptake and the lowest plasma lactate concentration were more hypoxemic and hypercapnic. The Standardbreds, studied under our laboratory conditions, did not have constant LRC and had lower f with higher V(T) than did Thoroughbreds under similar experimental conditions. Despite these differences in breathing strategy, the Standardbreds did not have higher V(E) than did Thoroughbreds, and they were hypoxemic and hypercapnic. The fact that these Standardbreds, which obviously freely selected their breathing strategy, were unable or unwilling to adopt compensatory hyperventilation reinforces the hypothesis that, in strenuous exercising horses, there could be a physiologic limit to ventilation, most probably related to mechanical factors, but independent of any LRC.

Two randomly distributed groups of thoroughbred horses were compared during a 12-week period for their cardio-respiratory and metabolic adjustment to strenuous exercise, training and detraining. The horses were trained following the same standardized schedule and were regularly investigated using standardized treadmill exercise tests (SET) of increasing speed. After the first SET and during the whole experimental period, a group of 6 horses received a probiotic (Bioracing) once a day while a group of 5 horses received a placebo. All other conditions were similar for both groups. During each SET, the oxygen uptake, carbon dioxide output, tidal volume (inspired volume), respiratory rate and expired minute volume were obtained using 2 ultrasonic pneumotachographs and a mass spectrometer. All the parameters were the mean of the values calculated during the last 20 s of the SET. Heart rate was continuously measured with a polar horse tester. Venous blood was sampled before and after the test and analyzed for various biochemical parameters. In both groups, training induced significant modification in most of the cardio-respiratory parameters, ie peak oxygen uptake, peak carbon dioxide output, respiratory exchange ratio, ventilation/min to oxygen-uptake ratio and oxygen-uptake to heart-rate ratio. After the 3-week detraining period, most of the values were again similar to the pre-training values in both groups. However, the training-induced modifications of most of the cardio-respiratory parameters occurred earlier and were proportionally greater in the probiotic-treated group than in the control. The respiratory coefficient decreased in the control but not in the treated group. All other parameters changed similarly in both groups. This suggests that Bioracing could modify the physiological effects of training by improving some aerobic metabolic capacities for carbohydrate utilization, but that this effect occurs only during training and not during periods of physical inactivity [less ▲]

Scintigraphy of the respiratory system, a technique used extensively in human medecine, provides a direct and non-invasive measure of both total and regional ventilation and perfusion of each lung. This article remind you some nuclear notions and describes scintigraphical techniques for horses. The resuits of studies suggest that ventilation! perfusion scintigraphy provides valuable additionnai informations on regional lung function that are not obtainable from conventional investigations. The mucociliary clearance rates from the trachea can be determinated using scintigraphy and the differenttherapeutic drugs, which are claimed to increase mucokinesis, are successively presented. Methods of radiation protection in equine nuclear medecine are described [less ▲]

The purpose of this study was to try to assess the fitness of endurance horses by using a simple routine standardized treadmill exercise test performed before and after a training period. Seven endurance horses aged 7 to 13 years, unfamiliar with the treadmill conditions and competing in international championship were tested twice in an air-conditioned laboratory, i.e. before and after a 4-month training period. The test was preceded by a 20 min warm-7 period and consisted of 2 min walk and 2 min trot (4.2 m/sec) with a slope of 0, 2, 4, 6, 8 and 10 The whole test lasted 45 min. Venous blood was sampled before and 4 min after each test. Heart rate was continuously recorded before, during and after the test with a cardiometer. Rectal temperature, respiratory rate and body weight were measured before and after the test. The completion of the test induced a significant decrease of the body weight, a significant increase in packed cell volume, cortisol, white blood cells, proportion of granulocytes, lactate, free fat acids and iso-enzyme LDH 5, and no change in the ions and in the activity of the other enzymes. Training did not induce significant changes in blood parameters, except in hacked cell volume and cortisol. Training induced a significant decrease in heart rate at all exercise intensities and during recovery. It was concluded that the test proposed in this study is simple, safe, suitable for horses unfamiliar with the treadmill and applicable in a 1-day clinic routine examination. In these conditions, the most reliable parameter for the assessment of fitness in endurance horses seems to be the heart rate recorded during 2 standardized tests performed before and after a training period [less ▲]

Ten horses underwent a standardised strenuous treadmill exercise test, before, during and after which measurements were made of plasma beta-endorphin and cortisol concentrations, blood lactate, glucose, haemoglobin and pH, the activities of creatine kinase, lactate dehydrogenase and aspartate amino-transferase, and heart rate, oxygen uptake and expired minute volume. The correlations between the exercise-induced response of beta-endorphin and the changes observed in the other physiological measurements were examined. There was a large variation in the beta-endorphin response of the horses to exercise. The increase in beta-endorphin was correlated significantly and inversely with the treadmill velocity at which maximal oxygen uptake was reached. It was also significantly and directly correlated with the heart rate during recovery, the increase in plasma lactate concentration and the change in blood pH, indicating that the exercise-induced increase in beta-endorphin concentration was smaller in horses with a higher aerobic capacity [less ▲]

Bovine muscle biopsies were analysed for fiber type and capillary density by the acid ATP-ase and amylase-PAS methods respectively. Samples obtained from Belgian blue double muscled (DM) calves were compared for their fibre type, size and vascularization with samples from Friesian (F) calves. The animals were sampled both at 2 and 7 months of age. Changes in histochemical composition occurring with ageing, independently of the breed, and differences related to the muscle sampled by comparing biopsies obtained from the longissimus dorsi (LD) and gluteobiceps (GB) muscles in animals of both breed were also investigated. Independently of age and muscle, fibre type I percentage and area were significantly higher in F than in DM muscles. Type IIa area was significantly larger in F than in DM, while fibre type IIb percentage and area were higher in DM. The number of capillaries/mm2 was significantly higher in F than in DM. Fibre type IIa and IIb percentage as well as the diameter of the three fibre types was significantly higher in the oldest animals. Finally, independently of age and breed, fibre type I and IIb percentages were significantly higher in LD but lower in GB. The results mainly demonstrated that Belgian blue DM muscles present a higher proportion of IIb fibres and a lower capillary supply than F muscles. [less ▲]
