About the Modified Bruce Treadmill Submax Test
A sub-maximal test takes between 6-18 minutes depending on the client’s fitness level. The test
involves a change in speed and grade every three minutes, so the incremental increases of
exercise intensity are relatively large for each stage (2 to 3 METs).
