This study was carried out to determine the metabolic response to load carrying and inclined trotting during treadmill exercise in the horse. Five standardbred trotters, trained for treadmill exercise, were subjected to an exercise test with and without 10% of their body weight in the position of a rider and saddle.

Three standardbred horses were used in a 3×3 Latin square design trial to determine the effect of feeding diets containing different levels of carbohydrate, fat, and protein to exercise horses. Muscle and live glycogen concentrations were significantly lower after the long slow exercise test when the horses were fed high protein and high fat than fed the commercial sweet feed diet.
