Maintaining the difference between AeT and AnT

    I’ve been using TFTNA principles for several years now, and just started one of the running training plans, so re-tested my AeT and AnT. I calculate about a 15% spread between the 2, so I feel good about where I’m starting.

    I’m confused about how the training effects will alter these numbers. I know it’s irrational to be concerned that getting fitter may cause problems, but it seems like if all is going well I may see my AeT HR rise, and if so I’m at risk for dropping below that 10% buffer, indicating aerobic deficiency. I’m less confident that, at age 41, I will see my HR at AnT rise (but maybe I’m really off-base there?). Should I be watching these numbers carefully? Or do I just trust the process and hope/assume that my pace at AeT will improve but the HR will stay constant?

    Aerobic deficiency is when the gap is greater than 10%. Mainly once you narrow the gap you’ll need to spend more time in z1 and less in z2 in terms of how it affects your training plan.

    Sure, it will help you to learn about how your body is changing and responds to training load.

    Or do I just trust the process and hope/assume that my pace at AeT will improve but the HR will stay constant?

    You don’t need to hope/assume anything, follow the training with at least 75% adherence (i.e. if you skip/miss more than 25% of the program…one can’t say the program worked/didn’t work) and you will find out for yourself if your pace @ AeT will improve šŸ™‚

    Good luck!

    Uh… if AeT HR rises (and gets closer to AnT), then the gap will close and the percentage difference will decrease.
