View Full Version : Energy Systems - ATP/Glycogen replenishment

Can't quite remember this one:

Glycogen - used locally in muscle or circulate in blood stream to provide energy?

ATP - Same question.

I'm just on my phone now so researching is slooooooow.

Muscle glycogen can't leave your muscle. ATP/CP, same thing.

K, so that's all local to the given muscle.
So when you use up your store of atp it gets replenished by glycolosis or CP, but when you run outta your store of muscle glycogen is that replenished by way of blood glucose?

Everything you want to know about Glycogen. (http://www.exrx.net/Nutrition/Glycogen.html)
The cells of our body store their energy in the form of ATP (http://en.wikipedia.org/wiki/Adenosine_triphosphate). The amount of work our muscles can perform is a direct consequence of the amount of ATP they have stored as well as the ease with which ATP is regenerated. So taking creatine enhances physical performance by increasing the number of times that ATP can be recycled during physical exertion without increasing the absolute amount of ATP stored within our muscles.
