You are right there are so many different terms out there to describe what you are training.
When I refer to aerobic capacity I am referring to the your aerobic threshold, which is much lower than FTP. Some would define this as the defection point on a Blood Lactate vs. Power curve.
MAP or Aerobic Power to me at least is different then Aerobic Capacity.
I am guessing to match our vocabularly
Aerobic Base = Aerobic Capacity.
LMN: Thank you for helping us get our terminology in snyc.
Now I'm curious about the physiologist speaker--what did HE mean by Aerobic Capacity? Did he discuss what he meant by that? I think if he meant aerobic base/fitness, then his statement has very different implications than if he meant maximum aerobic fitness (i.e. vo2 max or close to MAP).
I ask because I've always associated the term "Aerobic Capacity" with "Maximal Aerobic Capacity", but apparently, to an exercise physiologist, "Aerobic Capacity" is a more generic term without specific meaning--see the quote below from Andy Coggan a well-known cycling exercise physiologist (not sure if he was your speaker) from 2001 that I pulled from the google groups wattage forum.
Quote from Andy Coggan (google groups wattage forum):
""Aerobic capacity" is a bit more of a generic term...if you say
"MAXIMAL aerobic capacity", then to an exercise physiologist that is
synonymous with maximal oxygen uptake (VO2max). Having a high VO2max is
very important, since it sets the upper limit of your rate of aerobic
energy production, but the fraction or percentage of your VO2max that
you can utilize for more than a couple of minutes at a time is
determined by your lactate threshold. W/o the modifier "maximal",
however, the writer/speaker could be referring to a number of different
physiological properties...inclunding, quite possibly, lactate
threshold!"
