Carbohydrate consumption restores liver glycogen but not muscle glycogen in well-trained cyclists, indicating different replenishment rates.

After consuming carbohydrate, liver glycogen increased significantly, fully replenished within 6 hours, while muscle glycogen remained below pre-exercise levels at 12 hours.
Exercise reduced muscle glycogen from 159 ± 32 to 56 ± 19 mmol/l and liver glycogen from 166 ± 40 to 110 ± 44 mmol/l, showing significant depletion.
Using carbon-13 magnetic resonance spectroscopy, muscle and liver glycogen were measured at multiple recovery time points after carbohydrate intake at 10 g/kg body mass.
Ample carbohydrate ingestion quickly restores liver glycogen but cannot fully replenish muscle glycogen within 12 hours of recovery post-exercise.

Fuchs et al. (2025) studied this question.
