The assessment of a normal work capacity is made by evaluation of the peak oxygen uptake (VO2 peak). The normal value for oxygen uptake is based on sex, age, and weight.

The predicted peak VO2 is determined by the patient's age and sex. This value can be further refined for sedentary individuals by a three-step process (see below) that adjusts the predicted value up or down based on a comparison of the patient's weight and their ideal body weight. The predicted normal values for sedentary men and women from Wasserman et al are described below.
