How Eating Carbohydrates Affects Sugar Storage in Human Liver and Muscle

1 g/kg body mass of glucose or sucrose is sufficient to initiate postexercise liver glycogen resynthesis.

• Glycogen resynthesis in the liver was observed after glucose (13 +/- 8 g) and sucrose (25 +/- 5 g) ingestion, with no resynthesis during the control trial.
• No significant differences in muscle glycogen resynthesis were detected across trials.
• A positive correlation was found between carbohydrate load and liver glycogen content changes at multiple recovery intervals (30, 90, 150, and 210 min).
• A modest relationship was noted between changes in liver glycogen content and subsequent exercise capacity, although no significant differences in mean exercise time were observed among trials.
