Comparative Effects of Muscle Work and Insulin upon Plasma Amino Acids in Eviscerated Rats.

Abstract
Stimulation of muscle has an insulin-like effect upon the glucose tolerance of the eviscerate rat. In the rat, the effect upon glucose tolerance of a combination of muscle work and optimal doses of insulin is greater than of either one alone. Insulin suppresses the rise in plasma amino acids following evisceration of the rat but muscle work does not.
