What Does All This Mean?
- More energy
- Greater Stamina
- More muscle for a faster metabolism
When the body can't find enough glycogen (the form in which carbs are stored) in the blood, it starts breaking down amino acids (protein), which, of course, are the building blocks of muscle.
Some of the by-products of this breakdown include ammonia and urea, so if you find a lot of those by-products in a blood sample, you know that protein is being broken down.
However, by simply taking 5mg. of caffeine per kilogram of body weight an hour before a workout, the cyclists in the study avoided this breakdown.
The researchers theorized that caffeine increases blood glucose so that the working muscles wouldn't have to feed off muscle.
This was further confirmed by the increase in blood lactate levels, which is indicative of glucose being used as fuel (instead of amino acids).
Since we're not professional cyclists nor do we have to meet the demand of that type of training, I think a lesser amount of caffeine will work just fine.
