Exercise enhanced the uptake of glucose and FFA in healthy men. The arteriovenous
insulin gradients were positive at rest and in the recovery period. During and after
exercise the arteriovenous insulin differences reversed, regardless whether the insulin
concentrations were elevated or not. The reversal of the arteriovenous insulin differences
during and after exercise is consistent with a release of insulin from peripheral
stores. The mechanism of exercise enhanced uptake of both glucose and FFA are discussed.
