How is VO2 reserve calculated?

Explanation:
VO2 reserve represents the portion of oxygen uptake available above resting needs. It is calculated by subtracting resting VO2 from maximal VO2. In formula form: VO2 reserve = VO2max − VO2rest. This difference is what exercise prescription uses to set intensity, often by multiplying the reserve by a desired intensity and then adding the resting VO2 to get a target VO2. For example, with VO2max 45 ml/kg/min and resting VO2 5 ml/kg/min, the reserve is 40 ml/kg/min, and a given intensity would be calculated from that value plus the resting amount. It’s not a percentage of VO2max, it’s not equal to resting VO2, and it’s not a direct calculation for lactate threshold.
