Glad to share. I used the technique linked to on this site (I pasted it below). I know the guys now say that they don’t prefer the nosebreathing test in lieu of a cardiac drift test but I saw the nose breathing test before I read that new stance. 🙂
Indoor DIY Guide to Determining Your Aerobic Threshold: Treadmill Test
Incidentally, and I’ve been meaning to come back and comment on this but forgot. I said I used to train by “MAF” heartrate which is 180 minus age which puts me in the mid to low 130s (133 right now, 132 in a few weeks).
I wanted to get tested so I could see if I had ADS or not and if not could finally start doing some upper-intensity work instead of all the MAF running. Well with an AeT of 149 and a AnT of 164 then I determined I don’t have ADS and should do most of my non-intensive work in Zone 1….which is 20% under AeT, which is also about 134. So pretty close to MAF! 🙂
