Each stage of a graded exercise test lasts
3 minutes (unless otherwise stated in the test instructions).
Heart rate is recorded during each minute, but only the heart
rate
from the last 2 minutes of a stage is used to calculate the average
heart rate for that stage. The heart rates for the last 2 minutes
of each stage must be within five beats of each other (indicating
steady state), or the client must continue for additional minutes
until 2 consecutive minutes meet this criterion. Let's say that
the following data are collected in a test conducted on a 43-year-old
woman:
STAGE
MINUTE
HEART
RATE
2
1
112
2
116
3
118
In this case, the last
2 minutes of the stage elicited heart rates that were within
two beats
of each other, therefore meeting the five-beat criterion. This
client is ready to move up to the next workload.
