Aerobic Base Endurance. Importance of Zone 2

@T_Field

Aerobic adaptation will certainly occur in zone 3, but there will be a higher stress response.

No science to back it up, but from all the low HR training researching (and practice) I did last year, I’m going to say the stress response may be dependent upon HR. That might be a reason enough to keep your Z2 rides strictly Z2…until your aerobic capacity allows for Z3 power.

I believe it was Seiler (et al) who found that “highly trained subjects have rapid autonomic nervous system recovery after long, slow distance sessions” and “exercise below the first ventilatory threshold causes minimal disturbance in ANS balance”.

re: adding volume The conversation started with adding more Z1 and Z2 rides and then turned to not inflaming the sympathetic nervous system (by adding more volume) and trying to focus on parasympathetic nervous system boosting (non-cycling) activities.
