Difference between vo2 and anaerobic sessions

Hi all

Quick one, what’s the difference between vo2 intervals and anaerobic?

I can smash anaerobic sessions out no problem but struggle with vo2

Anaerobic:
The primary goal is to improve maximum aerobic capacity, or the endurance that allows you to work harder and longer…

Ansel Adams

VO2:
used to expand aerobic and anaerobic capabilities as well as increase a rider’s ability to tolerate high levels of acidic accumulation and stress, both physiologically & psychologically.

Table 2 of this link nicely shows expected physiological/performance adaptations resulting from training at different intensities with zone 5 being VO2Max and zone 6 being Anaerobic. The more checkmarks the higher the impact.

Don’t forget that what TR is doing, is taking an anaerobic power target, and turning it in to a workout that is stressing your VO2max capabilities. If you don’t have a developed enough aerobic system, you won’t be able to repeat higher power targets

A truly anaerobic capacity workout will have complete recoveries between sets, usually a work rate of 1:2

Like this one:

Once you start doing workouts that include that power target on shorter rest, you are adding stress to your VO2max as well. you have to have both developed enough to hit target throughout the series.
