I’m wondering if it is always necessary to bring your AeT within 10% of your LT before switching out of your aerobic base training mode? I was thinking about how two athletes who start training with the same AeT and same starting volume but different LT (by say 20 bps) might be prescribed to train differently (i.e. Z3 runs) after a certain time just because one athlete gets their AeT within 10% of their LT sooner, assuming both athletes increase their AeT at the same rate within the training window of both being outside 10%. I’m wondering if introducing different training stimuli should be based on certain AeT values, at a certain pace, or something else instead of proximity to LT?
I’m an ex crossfit athlete with a 190 LT and I’ve built my AeT to 160 bpm so far. I’m wondering if I should continue with long Z1 and Z2 or if I should begin Z1 and some Z3 in my efforts to most efficiently reach higher AeT values.
Thanks so much in advance!
