Postexercise muscle glycogen synthesis with glucose, galactose, and combined galactose-glucose ingestion.

ABSTRACT: Ingested galactose can enhance postexercise liver glycogen repletion when combined with glucose but effects on muscle glycogen synthesis are unknown. In this double-blind randomized study participants [7 men and 2 women; V̇o_2max: 51.1 (8.7) mL·kg^-1·min^-1] completed three trials of exhaustive cycling exercise followed by a 4-h recovery period, during which carbohydrates were ingested at the rate of 1.2 g·kg^-1·h^-1 comprising glucose (GLU), galactose (GAL) or galactose + glucose (GAL + GLU; 1:2 ratio). The increase in vastus lateralis skeletal-muscle glycogen concentration during recovery was higher with GLU relative to GAL + GLU [contrast: +50 mmol·(kg DM)^-1; 95%CL 10, 89; P = 0.021] and GAL [+46 mmol·(kg DM)^-1
