THE ACTION OF EXERCISE ON KETOSIS

Abstract

Rats in a state of ketosis show an immediate drop in the blood ketone level after a short bout of heavy exercise. During 3-4 hrs. thereafter there is over-production of ketone bodies such that the blood values in exercised animals go to higher levels than in controls. These results support the view that in ketosis exercise increases the oxidation of ketone bodies and also causes the liver to produce them at a higher rate. In man these changes were not demonstrated after light exercise but the drop during heavy exercise was obtained.
