Coaches! Happy Monday!

I just did the HR drift test and if I’m interpreting it correctly, it seems like my AeT has risen quite a bit since the last time I did it on 19 April, when it was 139.

These are the results:
Avg HR for the whole test = 141 (avg for first half of the test = 141; avg for second half = 142)
Pw:hr (no longer Pa?) = 1.42

I’m not super keen on having to do the test again … could I estimate my AeT at 144? I’d rather shoot low than high, to keep myself in check.

On a related note, my running form and my leg and core strength have all significantly improved since I last did the test. How much of the increase can be attributed to increased aerobic capacity and how much to better form and greater strength?

Thanks!

CORRECTION. Pw:hr = 1.22

Hi Jane,
Congratulations!
The analysis should still show Pa:Hr, is one of your other settings changed in TP?
And yes if that is the data then no you do not have to do the test again and estimating 144 as AeT is appropriate.

As for this question:
On a related note, my running form and my leg and core strength have all significantly improved since I last did the test. How much of the increase can be attributed to increased aerobic capacity and how much to better form and greater strength?

That my dear is something I cannot calculate, however I can tell you they both contributed significantly, you have a more efficient engine aerobically and also mechanically so YAY, that’s why you’ve had a significant increase in your AeT.

Strong work on all fronts!

Thanks, Carolyn and Maya 🙂 I’m really pleased!

Regarding pw vs pa, I think the issue was that I only had HR showing and not M/KM. I just redid the analysis with both showing and now Pa:hr is 0.84.

I still think I’m going to go with 144 as my AeT, though, knowing that I have a little wiggle room, because I too easily get enthusiastic and exceed AeT, so confining myself to a slightly lower bound will probably work out just right overall.

Is there a rough comparison for RPE and HR zones? For example, tomorrow is warm up 20 min @3-4 RPE and active for 30 min. @4-6 RPE etc. How might those fit into my HR zones? Thank you

Hi Catherine,
Zone One would be 3-4, Zone two 4 – 6.
Best,

Is the Pa/Hr, the statistic to focus on? Mine was 8.10, which seems high, but that includes that I included the first 15 min. warmup. I tried to drag across the screen from the time that the work out ended until the end for one hour, but I did not see the results.

Rachel, if you’ve dragged the vertical line to highlight the 1 hr of the test, the results should show in the top r/h box of stats. It usually takes a while for it to populate.

I have done the test twice now – my first time was running on trail and my pa:HR was >10 and the second time was >7 which was on flat dirt road with average pace 10-11 min/mile and HR in low 150s. I feel like my effort is minimal. Maybe I’m more out of shape than I thought and I need to walk to get my heart rate down and pa:hr down?

Hi Jeanie,
Yes since we are testing for aerobic threshold, top of zone 2, we need you to slow down until that Pa:Hr is 5% or less. Many people train too hard most of the time and don’t really know what it feels like to be aerobic which is the level of output we really want to be working at when doing big events/long mtn days, so we need to condition your body to do just that. Hence the focus on the lower intensity work. It doesn’t mean you are out of shape but you may have a classic issue we often find with many athletes: Aerobic Deficiency Syndrome ADS which is what we really want to correct. Here’s a great podcast talking about just that!

Hi Rachel,
Yes for the AeT test we are looking at the Pa:Hr being 5% or lower to be able to set the top of your zone two. Don;t worry about that number for other workouts as it will vary significantly with terrain. However for this test yes. As Jane mentioned highlighting the WO portion should give you your accurate HR Drift. If it’s higher than 5% then your AeT is lower than the average HR for that effort.
