Insulin-stimulated glycogen synthesis and glycogen synthase activation after electrical stimulation of epitrochlearis muscles with different initial glycogen contents

Glycogen synthesis increases after muscle contraction and during insulin stimulation, and insulin-stimulated glycogen synthesis is enhanced after contraction. We hypothesized that the initial glycogen content influences the magnitude of additive effect of contraction on insulin-stimulated glycogen synthesis. Contraction and insulin had full additive effect on rate of glycogen synthesis measured af…
