HRM - AT - LT - :LBP training advice and resources sought.

  1. 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

    This will depend entirely on your goals. The mixture of intensities, times and frequencies will be
    dicated by the type of races or health goals you have. A person training for an IM will spend a
    higher percentage at lower HR's than someone training for a sprint.

    Again dictated by multitude of factors include goals, age, ability to recover etc. Two
    people same age one may be perfectly OK doing high intensity workouts 3-4 times a week the
    another may breakdown under the same training.

    Depends on how scientifically or how laymen you want to go. I highly reccomend Joe Friel
    triathlete training bible. It pretty much lays out wokouts, how much, what type and when in
    the season to do them. You'll still have to figure out your goals and find out what your
    body can handle but the book sets up some solid guides. If you want some really indepth
    scientific stuff, check out the Lore of Running by Tim noakes. Although this deals mostly
    with running it reads more like a scientific journal than a book and weighs about ten lbs.
