Many enthusiasts and intercessors talk about a superfast refill of carbohydrates after exercise. Why carbohydrates? You need those during exercise, but after? You also have a lot of recovery products that contains surprising amount of fat and carbos.
Pure protein to fill up your reservoirs. You can feel comfortable that your muscles are saved, all surplus of proteins (what body doesnt need) are converted to carbos/glucose by your body. Driving your body more empty of carbohydrates while a period of structured training, just makes it more comfortable with that balance and probably got a boost later on with filled reservoirs.
This Q excluding "wear out completely" exercises, which purpose is a maximum carboload before an important competition. The Q is more about the regular training purposed to build up stronger endurance while the season. I would buy many of the promoted products regarding recovery if it's for for spontanouos competitors and joggers that likely are well-rested between competitions and heavy exercices.
What are your ideas here? How do you eat/fill after cycling? Wo you know some references to pure protein theory (or evidence for the opposite)?
