And yes, your body will run out of glycogen in about 2-3 days even without any workouts, if you don’t provide it from vegetables.
Really? Where have you heard this? I ask because bodybuilders and/or just recreational weightlifters that look to fully glycogen deplete weight train for at least three days in order to deplete. If depleting fully was possible by not weightlifting, then why lift weights? I remember reading something like 8 days without weightlifting or something like that (I could have just made that up).
I believe I came across i’ve come across it in a lot of discussions about low-carb/keto in general.
It only takes runners an average of 3-4 hours of running in marathons to ‘hit-the-wall’. Thats 3 hours of work. (same for 3 1 hour weight training sessions?)
Lifting weights makes the body more insulin sensitive in muscle so that there is a super-compensatory effect on a carb-up day.
The brain it self will use 120gm of stored glycogen a day. Muscle (at rest) uses ~40gm a day. blood cells require `40 gm a day.
And the average individual stores about 400gm of glycogen. But theres a limit to its depletion, the lowest it will go is 50 or something. Below a certain level (20/30 i think) people end up in the hospital.
so 350gm/160gm = 2.18 days. athletes may store a little more.
Wouldn’t that really depend on the type of athlete and their development of fast/slow twitch muscle? I had thought (perhaps incorrectly) that the rate of glycogen depletion was one of the differences in the muscle types making one much better suited for endurance than the other.
Does anyone know?
Yeah, type 2 fibers rely much more heavily on glycogen than type 1 fibers. So, if a person has more type 2 fibers in their muscle makeup, they should deplete glycogen at a higher rate. I’ve also read that on average, most people’s fiber types are distributed about the same.[/quote]
^ that is interesting. I never knew that happened. Does it then mean that a person with largely ST fibers will store less glycogen as well?
