Very strenuous exercise can stimulate the liver to release extra glucose into the bloodstream, due to an increase in adrenaline. Blood glucose can continue to drop for hours after exercising, so test your levels at least twice: once immediately after, and again a few hours later. Since more intense exercise prolongs the glucose-lowering effect, be careful after strenuous workouts by not indulging in heavy food servings or sweet drinks.
