I've found my lactate disappearance studies--the best of them in Equine
Exercise Physiology 3, 188-195, 1991: Marlin, et al. And from another study
on different forms of post race activity (standing, walk, trot, easy gallop)
from the earlier work, EEP 2. With active recovery (walking) whole blood
lactates will fall linearly, at the rate of about 20 mmol/L /hour. So, if we
see a 15 mmol reading at 40 minutes, we can extrapolate a peak lactate of 15
+ (20 *.67), or 15 + 13.4, or 28.4 mmol/L. Similarly, a 12 reading gives a
25.4 peak. A 12 reading at 45 minutes would then indicate a peak of 12 + (20
* .75) or 27 mmol/L peak.
However, at lactate values over 15, peak lactates occur at 5 minutes post ex.
Thus, we'd subtract 5 minutes from the recovery timing. Doing that, our 40
minute recovery becomes and 35 minute recovery. Thus, our formula changes
slightly: 12 + (20 * .58), giving 12 + 11.6 or 22.6 mmol/L. I'm satisfied
with this formula: ((Sample time-5 min) /60) + reading= peak.
Does this sound logical to you smart whippersnappers?
