oxygen as the primary source of fuel. It makes no difference what you
are doing when you exercise and induce this state.
Quoted message said:That makes sense.
I hope so. It's one of the ways I make cents.
Quoted message said:Perhaps I did not ask the question the right way.
Since I don't seem to breathe nearly as hard, would rock climbing be
'less' aerobic than running?
Yes in the sense of taxing or working the cardiopulmonary system.
No in terms of getting the correct amount of CP workout. You can do
that walking briskly 5 plus times a week. Never get out of breath when
I do that.
So, out of breath is not necessary to meet your aerobic goals for CV
health purposes.
Quoted message said:Part of the puzzle is about the heart rate. In climbing, I will get to
the same heart rate as I do running, and it will be sustained for
10-20 minutes in 'exercise' climbs. If I run for the same time period,
with the same heart rate, I seem to need to breathe much more. I'm
trying to understand why that happens.
Tracking exercise events is a very difficult thing. For instance, when
you run, you are absorbing and generating consistent forces with the
ground. That is a much more taxing event than climbing. Not nearly as
much force generation/absorption. Think about bodyweight in both
situations.
Quoted message said:From your description above it would seem that breathing might be a
better measure of 'aerobic' than heart rate. Is that true?
Personally, I think that aerobic exercise should be judged first by
its health parameters. That is, how much blood flow and O2 exchange is
happening. How much peripheral blood flow and additional blood
transport is created.
Quoted message said:But, is sustained near-max heart rate a better measure of the cardio
benefits than the 'aerobic' measure?
I believe so. A sustained increase in heart rate is what you are after
and what is easiest to track.
