Fructose and Galactose Enhance Postexercise Human Liver Glycogen Synthesis

Liver glycogen concentration increased at rates of 24 ± 2 and 28 ± 3 mmol·L(-1)·h(-1) with fructose and galactose, respectively.

• Fructose and galactose drinks resulted in faster liver glycogen synthesis compared to glucose.
• The rate of net glycogen synthesis was higher with fructose (8.1 ± 0.6 g·h(-1)) and galactose (8.6 ± 0.9 g·h(-1)) than with glucose (3.7 ± 0.5 g·h(-1)).
• Liver volume increased significantly with fructose (9% ± 2%) and galactose (10% ± 2%), but not with glucose (2% ± 1%).
• Maltodextrin drinks with fructose or galactose may be more effective for restoring liver glycogen during short-term recovery after exercise.
