I was always under the impression that the use of terms aerobic endurance (AE) and muscular endurance (ME) was an attempt to apply a descriptor (for a layman's purpose) to the type of training one can do to improve muscular vs cardiovascular fatigue. Yes, I'm sure he realizes those two go hand in hand (not either/or) but there are many ways to improve your endurance and I believe Friel was just using a specific term to help the athlete associate the use of turning a bigger gear for a long(er) period of time via a specific workout which just so happens to make the muscles
feel like they're working harder than than the lungs.
Sometimes it actually works much better for an athlete when a coach uses layman-like terms even at the expense of deluding the scientific or real definition. Although, it is amazing how many people think they have an ME limiter simply because of how much their muscles (and not their lungs) hurt by mile 18 of the run.

I think you hit it here. What I don't understand is just how dumb he thinks the layman is. By this I mean, in order to read his book and get anything out of it, you must be reasonably intelligent. Trust me, I've looked through about 15 tri and cycling books recently and his is one of the more advanced. A term like "muscular endurance" and his lack of a *reasonable* definition for it is the kind of answer you give an audience that you don't expect to really learn anything, but you need to give them a reason for doing the day's workout. This is completely inconsitent with everything else he writes in his book. It's like going to calculus class and having the teacher telling you to just start moving numbers around and making up a name for the process like "equation enhancing."

The biggest problem (and confusion) I had coming into triathlon was that he carried this term over into running and you simply don't have that sensation (at least none of the runners *I* know do...maybe thick legged bikers do). Why couldn't he take it one step further and say, "I define this term to mean (what you just said). This typiclay happens around CP60. There is a change that occurs in your body that is beyond the scope of this book, but it is important to work on. Don't confuse this with the feeling you get in your legs after 6 hours of riding or hammering up and down hills. That is different."......if in fact he IS talking about LT (we still aren;t sure).

And that is my beef. Either these people are stupid, or it is a poorly described concept. I'll go with #2 (though his book is better than most).
