To go back to the original question, I did some research and it turns
out Tabata's second study was with one group of people doing the
20s/10s at 170%
of VO2max and a second doing longer intervals with 200% of VO2max, and
the shorter intervals worked better to tax both aerobic and anaerobic
pathways... so since his people were using 170% of
something-I-don't-quite-
understand instead of 200%, I guess it's not a total bastardization to
hold
back from going completely all out.
VO2max power output is, roughly, what you can average doing a five
minute maximal test in your exercise of choice. If you're a runner, look
at your mile time, if you cycle, your 4k, if you row, your 2k; compare
to a chart. The number you get will depend on a lot of things besides
basic fitness, like which sport you do, how efficient you are, et
cetera.
However, the idea is that the limiting factor is how much oxygen you can
use. So if you discover that you can average 100W when you lift heavy
weights for six minutes, then that doesn't tell you much about VO2max.
Your legs fatigued well before your CV system.
Given everyone here lifts weights, going all out for 20 seconds in most
exercises will be way over 170% of VO2max.
OK, that sounds relevant. But OMG the thought of doing 5 minutes of
thrusters in order to determine my VO2max sounds... painful. I think I'll
just stumble along from where I am.
Testing VO2max properly is always painful. You can probably make a decent
guess by doing 3 minutes fairly hard, though.
If however you mean you'd have trouble with your muscles fatiguing first,
then you're not really going to get quite what you want out of trying the
Tabata protocol with that exercise.
I'd observe that when you go looking for Tabata and weights work together,
you find www.crossfit.com fairly fast - and I don't think those people do
too well with VO2max tests. For example, they have top rowing scores:
500m 1:20
1k 2:57
2k 6:41
5k 17:59
Now, the 500m score is pretty decent. The 1k score isn't too shabby. The 2k
score is not brilliant, and the 5k is a joke.
For contrast, my scores would be:
1:27
3:04
6:29
17:57 (haven't tested 5k for years, that's my half hour pace at rate 20)
I'm a lightweight, currently at 74kg. Good heavyweight scores are quite a
bit faster than mine.
