Prior exercise enhances passive absorption of intraduodenal glucose.
The purpose of this study was to assess whether a prior bout of exercise enhances passive gut glucose absorption. Mongrel dogs had sampling catheters, infusion catheters, and a portal vein flow probe implanted 17 days before an experiment. Protocols consisted of either 150 min of exercise (n = 8) or rest (n = 7) followed by basal (-30 to 0 min) and a primed (150 mg/kg) intraduodenal glucose inf...
متن کاملEffect of Intraduodenal Glucose Administration
Received for publication 24 August 1972 and in revised form 2 April 1973. INTRODUCTION The anatomic location of the liver, receiving the entire pancreatic output of insulin prior to its entry into the systemic circulation, and its ability to degrade insulin permits it to play an important role in regulating peripheral insulin concentrations (1). Although increases in peripheral insulin levels h...
متن کاملEffect of prior exercise on glucose metabolism in trained men.
Several studies have demonstrated that oral glucose tolerance is impaired in the immediate postexercise period. A double-tracer technique was used to examine glucose kinetics during a 2-h oral glucose (75 g) tolerance test (OGTT) 30 min after exercise (Ex, 55 min at 71 +/- 2% of peak O(2) uptake) and 24 h after exercise (Rest) in endurance-trained men. The area under the plasma glucose curve wa...
متن کاملDoes prior exercise affect oral glucose tolerance test results?
Background When oral glucose tolerance tests (OGTT) are repeated in individuals, relatively large variations in the magnitude of the blood glucose response often occur from one measurement occasion to another. Little is known about what causes this within-subject variability. One potential contributor may be the subject's prior extent of physical activity and/or the amount of stored glycogen pr...
متن کاملGlucose infusion attenuates endogenous glucose production and enhances glucose use of horses during exercise.
We examined the effects of increased glucose availability on glucose kinetics and substrate utilization in horses during exercise. Six conditioned horses ran on a treadmill for 90 min at 34 +/- 1% of maximum oxygen uptake. In one trial [glucose (Glu)], glucose was infused at a mean rate of 34.9 +/- 1.1 micromol. kg(-1). min(-1), whereas in the other trial [control (Con)] an equivalent volume of...
