Another thought: It’s probably worthwhile to get a lab test done. If aerobic capacity is large enough that drift tests are very fatiguing, then (IMO) they have limited usefulness. At that point, I think it’s worth being more precise via lactate or a gas exchange test.
Learning to trust the drift test
I’ve been trying to nail down my AeT for uphill hiking (my primary activity) and indoor cycling (secondary/backup/alternate activity).
I’ve been ramping up level of effort (slope/speed on treadmill, targeted power output on exercise bike) and looking for cardiac drift. What I think I’m finding is that in order to achieve cardiac drift of ~5+% on a one hour effort, I’m putting out an effort that violates all of the subjective measures of being within AeT (breathing intensity, perceived effort, indefinite endurance). If I achieve a small cardiac drift, I’m usually completely spent at the end of the hour test, I’m definitely not able to nose breathe, and my heart rate is typically 80-85% of what I think my max heart rate is.
I think from my reading that Cardiac Drift should be a more reliable measure than the subjective metrics, but I thought I’d ask here. Do someone people just not cardiac drift until further over Aerobic Threshold?
I am not a well trained athlete – I am new to endurance training.
I have significant data that I can post, just not sure what would be helpful yet.
