Ample carbohydrate ingestion allows rapid replenishment of liver but not muscle glycogen stores within 6 and 12 hours of post-exercise recovery

Carbohydrate intake of 10 g:kg body mass rapidly replenishes liver, but not muscle glycogen contents, during 12 h of post-exercise recovery in well-trained cyclists (Fuchs et al).pdf (1004.2 KB)

Interesting, but not super surprising? Muscle glycogen was about half replenished after 12hrs, so likely on track to be ~fully replenished for the next day’s workout.

I wonder what the liver does with the fructose that keeps getting ingested, after it’s at 100% at the 6 hr mark?

Turns it into fat perhaps or uses it for energy?

Yep. Turn into fat instead of store in glycogen muscle. IF there an excess in blood stream. It not gonna line up at the glycogen door and wait for insulin to bring it to the store. It gonna snatch away and to lipid store (Fat welcome house).

And Fat have unlimited store so be careful what you eat. Not all carbs will go to glycogen store. Some go lipid, some burn off, some will get in glycogen.

Generally, body tend to adapt and train to use what you eat. In this case you ingest carb, body use carb for energy for the most.

You also don’t appear to get a non insulin response to glycogen storage immediately after exercise as some people say.
