Hi. I find your question(s) very interesting–because I have similar ones.
When does one know if they no longer have ‘ADS’ (aerobic deficiency syndrome)? Is an AeT within 10% of AnT the best metric? An alternative method used on TP is to determine your current AnT and then take 75-85% (ie ~80% goal) of that (your running Z2 or aerobic zone) and confirm there is a <5% drift while in this zone for an hour. Which is best? Are there others?
I’m also curious, if know, what volume and duration of aerobic base training, on average, is required for most previously untrained and not overweight persons to not have ADS? There must be some ballparks here
