The test consists of four three-minute stages. Stage one is a

warmup stage. Stages two, three, and four are at ever-
ORKS
increasing workloads, with your heart rate measured during
the second and third minute of each stage. (If the two heart
rate samples in a given stage are separated by more than six
bpm, that stage is extended for an additional minute.)
The heart rate measured during the last minute of each stage
is compared mathematically with workload, and then
extrapolated to your age-predicted maximal heart rate (see
Appendix A). The workload corresponding to this heart rate is
converted to milliliters of oxygen per kilogram of body weight
per minute.
