FOIA It is a standardized multistage treadmill test for assessing cardiovascular health. This can also be converted to an estimated maximal oxygen uptake score using the calculator below and the following formulas, where the value "T" is the total time completed (expressed in minutes and fractions of a minute e.g. The speed must also be increased for each stage, and this increase in speed is set according to the standards of the Bruce Treadmill Test. Last medically reviewed on November 28, 2022. This protocol starts at 5 METs in stage 1 and then each stage is increased by approximately 2 3 METs modified bruce:the first 2 stages occur at workloads of 2.9 and 3.7 METs.
