Glycogen resynthesis is a (the?) crucial component of recovery.
But I'm not interested in a debate here. I'm interested in research about the effect of nutrition on recovery from exercise. Your claim implies that the usual advice to consume a protein–carbohydrate combination shortly after exercise is worthless. If you can cite literature to support that claim, it would be very helpful.
Actually, I made no such claim (but relax, I'm not looking for a fight for the sake of it, either).
But I did assume you were relating that glycogen resynthesis info to all of the things 341gerbig mentioned, ie, muscle growth, muscle soreness, recovery time, and improved fitness, with muscle building in mind, whereas the study seems to be dealing only with endurance exercise and specifically recovery (and potentially improved fitness). Hasty reading on my part.
Incidentally, I think real-world studies with athletes are the most useful. The fitness industry is littered with studies showing altered levels of all sorts of different bodily chemicals that ultimately have little bearing on body composition or performance.
