Hi experts - I recently had a lactate test done on a velodyne stationary cycle using a lactate pro
blood test by a sports trainer. I'm glad to get some results but after doing a little research on
the web, I'm confused about how to apply these results to training.
This particular sports trainer and many others, I've noted, are advocating power training (i.e. SRM,
powertap, etc.) over heart rate training as this seems to be more fashionable now, however, I'm not
willing to invest the $700 in a powertap and would rather just stick with a simple HRM even though
it may not be perfect.
The test showed that my anaerobic threshold was at 155-160 bpm @275 watts. As far as I can
determine, this was assessed only by looking at the non-linear deflection of the watts/BPM curve
(although he was testing lactate along the way).
He then determined that my lactate balance point (LBP) - the power level at which I can clear
lactate faster than it accumulates was at a heart rate of 135-140. This was accomplished by backing
was off from the AT to let the body flush lactate and then steadily increasing the power until
lactate was no longer decreasing but started to accumulate again.
My questions are these:
Should I be training using intervals at the LBP (HR = 135), as some web sites advise, or more at my
AT (HR = 155), as this trainer advises? He advises 2 work outs a week of 30 minutes total at AT -
starting at 15x2 min intervals and increasing to 2x15.
How much time should I spend over AT in anaerobic sprinting without doing too much damage to recover
from. I cycle about 100 miles/week year round?
The HRM training books I've looked at seemed unhelpful and full of fluff so I was wondering if these
issues were addressed scientifically on the web or in some book I haven't seen.?
Thanks in advance Chris
