Glycogen Depletion Symptoms
Glycogen depletion symptoms are heavy legs, pace collapse, and foggy focus on long efforts—usually fixed by carbs unless confusion suggests hyponatremia.
Glycogen depletion symptoms include heavy legs, rising heart rate at the same pace, irritability, blurred focus, and a sudden inability to hold race effort—distinct from dehydration cramping alone or hyponatremia confusion. Symptoms creep then cliff on long efforts.
Fast carbs may rescue training bonks; medical symptoms need aid.
Common questions
-
