What is your preferred method of testing anaerobic threshold?

"I have been getting frustrated using AeT and thought I was just doing something wrong/not reading the data correctly... If not aerobic threshold, what is your preferred method of testing anaerobic threshold?"

Detraining: How far can you fall?

Over three years of detraining, my anaerobic and aerobic threshold speeds have declined 23% and 26%, respectively. At a climb rate of 1,000 meters per hour, my heart rate has increased 37%. Detraining, age, altitude—and attitude—are all factors.

Lactate Test #5: Progress

On September 18th, I did my fifth lactate test for the season. As with previous tests, I did both the aerobic and anaerobic portions on the same day with a break and some food in between. What does this lactate test show? Anaerobic capacity has increased In my last test,

Lactate Test #4: Stupid is as stupid does

Over a month ago, I did my fourth lactate capacity test of the season. I did both the aerobic and anaerobic portions on the same day, albeit with a break and some food between them. Since my last test in early July, I’ve been doing a lot of Local

Lactate Test #3: Moving in the right direction

Last week, I did my third lactate test of the season. As planned after my second test, I wanted to minimize glycogen depletion in the anaerobic portion, so I split the test into two parts. I did the aerobic part on July 2nd and the anaerobic on July 3rd. Since

Lactate Test #2: What happened to aerobic capacity?

On May 21st, I did my second lactate capacity test of the season. I planned on both an aerobic and anaerobic capacity check during the test. But the aerobic part of the test was too long. It likely caused a bit of glycogen depletion. Depletion would have compromised the results

Lactate Test #1: Where am I starting from?

On April 7th, I did my first lactate capacity test of the training season. A lactate capacity test tells you: * Your aerobic capacity by plotting ~2 mM/L and ~4 mM/L against pace and heart rate; * Your anaerobic capacity by measuring the peak lactate output during the test; and
