The test consists of four three-minute stages. Stage one is a
warmup stage. Stages two, three, and four are at ever-
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 6
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.
