I am interested in measuring maximum lactate accumulation rate (VLamax)
in running (or sports other than cycling).
I know that Wingate test or some variation of it is used on a bike
to determine VLamax and use the forumla:
Vlamax = (Lactate(after) - Lactate(before)) / (time(test) - time(alactic))
The trickiest part of the test seems to be the
length of the test (time(test)) and the time to
deplete PCr (time(alactic)) since those two
values dramatically impact the accumulation
rate. On a bike, one can use a power meter
and stop the test as soon as the power starts
dropping. In the following paper:
http://www.qucosa.de/.../1742-4682-11-25.pdf
they use time(test) = 15 seconds and time(alactic) to
be time when power output drops by 3.5%.
Questions:
1. What protocol people use to measure VLamax in other
sports like running and swimming?
2. How reliable are VLamax tests in the field (not in the lab
on an ergometer)?
3. Is there an alternative to measuring anaerobic capacity VLamax
directly and using a reliable proxy that is not so tricky to measure?
in running (or sports other than cycling).
