I should point out, when I did the Aerobic Threshold test that came out with a number of 146 my drift percentage was barely high enough to qualify for a successful test. So I may have been operating on a low Aet HR.
So I had a stretch over the Christmas holiday where I was down with an illness for about a week. Couldn’t train, had to rest. Took last week as a down shift/rest week, doing the more low end workouts to ease back into training. This week I started doing the training I had done a week or so prior to when I got sick as part of getting back to speed. But I also wanted to redo my Anaerobic and Aerobic Threshold tests to dial in my zones as I’m 8 week from an expedition on Orizaba and wanted my training leading up to that as accurate as possible.
Tuesday I redid the Anaerobic Threshold test and came out with a HR of 176 which was about where the prior test had said it should be. So I left that number alone in Training Peaks. Then I took a couple easy days, mostly focused on recovering from that workout and today did the Aerobic Threshold Test.
I came in expecting that the number probably would have moved as I’ve felt stronger and more capable during the process of this program. My Aet HR coming in was 146, so I aimed to start at 150, but incidentally actually started around 158. I decided to let it ride and see what happened.
Looking at the data on Training Peaks, My average HR for the first half was 162 and the second half was 170, and then I divided 170 by 162 which came out to 1.049, or a drift of 4.9% which would seem to be within the tests desired range. This would mean my new Aerobic Threshold HR would be 158, a jump of 12bpm.
That seems high… Is this possible? Normal?
I also divided the Anaerobic Threshold HR of 176 by the Aerobic Threshold HR of 158 and came out with 1.1139 or a difference between the 2 of 11.39% which is close to what you guys said is desirable.
Should I go with this new HR moving forward? I felt completely fine during both test. In control. Coming off the treadmill today my breathing returned to a resting state within less than 30 second after stepping off. I just want to work within the right HRs as I make this push towards the expedition. Thanks.
