Thanks so much for the replies!
@jswell Thanks for the clarification on HR zones in relation to UA. That makes more sense to me now.
@Scott Johnston Thanks for the reply and help with the results. I had not read the two articles you posted in your message. It was a case of going to the only place where I live that offers these tests and unfortunately I hadn’t thought of going to a university. The place works with athletes such as cyclists, long distance runners, swimmers and hockey players. I had spoken to them about my desire to focus on AeT and AnT, not VO2 max and they seemed to be on board. The warm up was 10 minutes on the treadmill and each stage of the test was 3 minutes long. Stage 8 is where I had to quit. So the test itself wasn’t quite 24 minutes long. It seems after reading the article about lab selection, that the warm up may have been too short. But the length of the stages seems good.
Time to eat some humble pie and start speed walking my way to a better aerobic base. ADS sucks, but I look forward to the results of the consistent,low intensity training.
