I did an AeT test today in the gym. A had guesstimated, based on my age, that this was 136bpm (which I thought was a bit low). I did a 15min warmup on a treadmill and picked a pace of 7.4kmph.
Average HR for the second half was lower than the first (137bpm vs 135bpm).
So I guess I need to pick an arbitrary HR that’s higher and redo it to find out the right amount? Say 140bpm?
Very curious, what’s your test protocol? I never encountered an AeT test
I think he means a AeT estimate based on HR drift as suggested here:
I’ve tried this a couple of times on the bike indoors and on a run outdoor but I can’t get a meaningfull result because I mostly have a negative decoupling for lower intensities (Seems to occur for quite a lot of people but couldn’t find an explanation yet). When I try to chase the point with ~5% decoupling, I am definitely way over my AeT…
When I do a LIT run, I usually start running more comfy after 30-45min resulting in a slightly higher pace for a slightly lower HR, even after a decent warmup of 20min.
137 vs 135 is insignificant difference, so based on that I would indeed try running at 142.
However, it is hard to maintain even effort for the whole hour. I’d say it would be pretty difficult to test using this protocol.
I’d rather use the ventilatory threshold (VT1) as a proxy for AeT. Basically, find a heart rate at which your breathing changes. AeT would be somewhere in between the end of nose-breathing and the beginning of laboured breathing when you cannot say more than a couple of words in a row.
I think that is good enough, no need for 1bpm precision
Exactly! Low intensity work is supposed to be in a broad range of 5-15 bpm below AeT. Not always right on the edge…
You’re right MedtechCD, I was doing the HR drift test. I have a couple of their books so have been loosely following their training advice. I appreciate that low intensity doesn’t need to be exactly at my aerobic threshold but I haven’t established any of my thresholds yet and have been struggling to stay in my guesstimated aerobic zone when doing any outdoor running. I figured best to get some data.
I did another test today, I was aiming for 142bpm and upped the pace by 1kmph, but it still was not fast enough - its a pain looking at my HR on my watch whilst trying to run! Results of first and second half were 140bpm average. I’ll try a little faster next time.
I was curious as to the Threshold pace option at the top of the intervals workout. I punched in 6kmph to see what it did. There isn’t a way to remove this value. Would this screw anything up within Intervals?
I’ve no idea what value to add here.
