Pnoe metabolic testing

  • Creator
  • #38328

    I’m looking to get a metabolic testing done using the Pnoe device. The person doing the test suggested the following protocol:
    – 15min warmup
    – 6% incline, starting at 3mph and increasing speed by 1mph every 3min until failure

    Is this a good protocol for determining AeT and AnT if training for races with big elevation gain? What will be the advantages/disadvantages of having the test done at 10% incline and increasing speed only by .5mph every 3min?

    For mountain sports, I would use the steepest treadmill incline that you will have regular access to (for repeated testing). 6% is pretty low-angle.

    If you do use 6%, then 1 mph increases are probably reasonable. At steeper inclines, I think 1 mph will be too severe.

    I prefer to use changes in pace rather than speed. When testing, I start with changes that are 30″/km and then gradually down to 15″/km when trying to dial in AeT.

    One thing: The PNOE website has that “smells like science!” feel. They use “the most famous nutritionist in the US”, a Crossfit owner, and a dietician as spokespeople. That doesn’t bode well for the accuracy and precision of the device… I would look for a proper lab.

    Thank you for the info Scott.
    I have done the AeT and AnT tests according to the UA recommendations (last year in August and one 3 months ago). On the last AeT test the heart rate drift was negative so I wasn’t sure if I’ve done something wrong or not. Unfortunately there are no decent labs close to where I live to do a proper test so Pnoe was the only alternative, and I was just curious on the results compared to the self test.
    What recommendations you have on a negative heart rate drift during the AeT test? Should I just retest starting at a higher HR? Current AeT is set at 160 which seams a little high, but again during the 1h test the drift was negative.

    Thank you,

    Negative drift… How long and gradual was your warm-up?

    What are you using for AnT HR?

    I warmed up for 15min prior to starting the 1 hour test (see attached file). Since I had my previous AeT value as 158 I started the test around that value.
    As for AnT I’m using 174bpm.

    Here is the zip workout since the original was too big

    Do you have the workout in Training Peaks? Can you post a link to the workout?
