What is the Bruce protocol treadmill test?
The Bruce protocol is a standard test in cardiology and is comprised of multiple exercise stages of three minutes each. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS. Stage 1 of the Bruce protocol is performed at 1.7 miles per hour and a 10% gradient.
What is the Bruce submaximal treadmill test?
Following a 3-min walking warm-up stage, the TMJ test requires participants to jog at a self-selected submaximal jogging speed between 4.3 and 7.5 mph at level grade until a steady-state heart rate (HR) ≤ 180 bpm (beats per minute) is achieved (George et al., 1993a.
What is Stage 3 Bruce protocol?
Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased. The modified Bruce protocol has 2 warmup stages, each lasting 3 minutes.
How fast does a treadmill go during a stress test?
During the test, the patient is on a treadmill or a stationary bike till he achieves at least 80% of the target heart rate. The target heart rate may be achieved faster in old people; young people and athletes take up to 20 minutes or even longer to attain the target heart rate.

The Bruce treadmill test is an indirect maximal oxygen uptake test. It is considered indirect because it estimates VO2 max using a formula and the person’s performance on a treadmill as the workload is increased. MHR ( maximum heart rate 220-age)by recording HR during test which can be used in training programs to set intensity.
How is VO2 max determined on Bruce Treadmill test?
The score is then determined based on a couple of formulas that determine the VO2 max of the runner, as based on the runner’s age, gender, and time. In general, the larger the Bruce Treadmill Test number is, the more “fit” an individual is.
