Scott, I think that is great that you guys will more or less move on from the max HR and % zones in a future edition (at least that is how I read it). I know it is hard to completely ditch them, but there are much more sophisticated methods which I wouldn’t consider to be that expensive relative to the amount of time sunk into training, the cost of trips, equipment etc.
Assuming the above is hinting at lactate testing, I would also hope there would be some additional material in relation how to use lactate testing. I’ve found the spectrum to be wide from “freds” wanting to just know their “anaerobic threshold” and train above that, to people using 4 mmol/l as the aerobic cut off, to some using 2 mmol/l as the aerobic threshold to some labs suggesting HR below the 2 mmol/l HR number to Olbrecht mainly using it as a marker(s) for the efficacy of the training period (meaning, one test means nothing, you need multiple tests, and you need time to figure out what is working).
In other words, it would be nice to have your take on how to APPLY the testing results. I personally looked at a CU physiology lab report and found it leave a lot of questions (mainly posed from the person who shared his information with me). I think after reading Olbrecht’s book and the “secrets of lactate” material from lactate.com, they have much better information on how to apply the testing and its results.
