50% of maximal rate of oxygen consumption for 60 min after being
denied access to food for 18 h and then 1 ) fed corn
(51.4 kJ/kg digestible energy), or 2 ) fed an isocaloric
amount of alfalfa 2-3 h before exercise, or 3 ) not fed
before exercise. Feeding corn, compared with fasting, resulted in
higher plasma glucose and serum insulin and lower serum nonesterified fatty acid concentrations before exercise ( P < 0.05)
and in lower plasma glucose, serum glycerol, and serum nonesterified
fatty acid concentrations and higher skeletal muscle utilization of blood-borne glucose during exercise ( P < 0.05).
Feeding corn, compared with feeding alfalfa, resulted in higher
carbohydrate oxidation and lower lipid oxidation during exercise
( P < 0.05). Feeding a soluble carbohydrate-rich meal
(corn) to horses before exercise results in increased muscle
utilization of blood-borne glucose and carbohydrate oxidation and in
decreased lipid oxidation compared with a meal of insoluble
carbohydrate (alfalfa) or not feeding. Carbohydrate feedings did not
produce a sparing of muscle glycogen compared with fasting.
