Bruce Treadmill Test Stages Stage 1: 1.7 mph at 10 percent grade Stage 2: 2.5 mph at 12 percent grade
Stage 3: 3.4 mph at 14 percent grade
Stage 4: 4.2 mph at 16 percent grade
Stage 5: 5.0 mph at 18 percent grade
Stage 6: 5.5 mph at 20 percent grade
Stage 7: 6.0 mph at 22 percent grade
I found the protocol for the test, each stage is 3 minutes long, so you can see that you get to a pretty steep grade around stage 4. And 10 minute miles at 22% is no joke either!!!
How hard they let you work must "depend" on something. When I did my nuclear stress test back in May, they chose a target HR of 144. With an LTHR of 178 and a MHR of 194, that's mid zone-1 for me. I made it to stage 4. I went in prepared for a workout...and left dissapointed. I should have asked how they come up with the target HR.
Even still....the tech asked, "You must workout a lot? Most people don't make it past stage 1/2."
