Leatt, P B., & Jacobs, I. (1989). Effect of glucose polymer ingestion on glycogen depletion during a soccer match. Canadian Journal of Sport Sciences, 14, 112-116.

Male soccer players (N = 10) were divided into two groups. One ingested .5 L of a glucose polymer solution before a game and at half-time. The other group ingested a placebo at the same times. Muscle biopsies of the vastus lateralis were performed.

Muscle glycogen change was less in the polymer group than in the placebo group. Blood glucose levels were unchanged after the game in both groups.

Implication. Glucose ingestion reduces net muscle glycogen utilization in soccer.
