Carbs & Fiber
GLUT4 is the door glucose uses to enter the fibre; glycogen synthase is the step that builds the same sugar past the everyday fill line. An open door only explains entry. Supercompensation is synthase still on after the tank was emptied.

Muscle
Supercompensation happens in the fibre that did the work, not as a whole-body hormone filling every tank. The rested contralateral leg stops at baseline on the same carbohydrate.

contrast · 1

Gut during exercise
Glycogen supercompensation is synthase inside the muscle still on after emptying; the gut during exercise is blood flow, the stomach, and two sugar doors before that sugar has entered the muscle. Do not merge them into 'just eat more carbohydrate'.

只有做过功的那条腿

Stop 1/4

Only the leg that worked

Glycogen supercompensation sounds like a race-week menu. What actually happens is more local: a muscle that has just been emptied will pack glucose into glycogen past its usual fill line.

In 1966 Bergström and Hultman had people ride one leg to exhaustion, rest the other, then eat carbohydrate on both sides. Glycogen overshot baseline only in the leg that had worked. Their own conclusion is hard: the enhancing factor sits inside those muscle cells, not in a circulating whole-body hormone.

This island is not how to eat before a race. It is which enzyme stays on after this tissue has been emptied.
