Sorry for my previous answer. I talked with Herb and was reading my own answer this morning again.
It is too complicated, and a lot of people think , my god are they clever, but the answer should be, that everbody can understand it in a simple way. The above answer was more latenglish. which is latin and english.
Here now a new try :
When ever we move we need energy. Now think our muscle as a group of people on a campground, planning to start a fire to get some energy.
There is the easy way of getting all the wood pieces and what ever can burn scratched together just arround the fire pit.
Advantage, it will be easy and we will have very fast a fire. Disadvantage , we will run out of fuel in a short time. Now one in the group has the idea to get some wood from further away and safe the already existing wood around the fire place.
The wood further away would be you glucose in the liver , or your fat storage.
As you see on the street , a lot of people often use only the energy arround the fire place , but would have a heck of a lot of wood a little bit further away . ?
Now coffein is that one guy in the group , with the idea to pick up some wood further away from the fireplace.
So using coffein will spare the glucose arround the fire place , in fact because everybody is now collecting wood from further away , it actually safes the wood arround the fireplace.
Taking coffein would work like that , and because burning fat does not create the lactate levels in your blood as burning glucose, , we will see in lower intensities lower level of lactate in your blood . This for people who use the 2 - 4 mmmol testing , your lactate curve will shift more to the right side, giving you the impression of a better performance.
Besides. The above fact is used in some nutritional companies like sponsor and others in bars, they claim improves your endurance ability. Now you know the rest of the story .
