While other factors like an individuals age are somewhat considered (for example, there is a different equation for young men and men), the Bruce Treadmill Test is primarily determined by the length of time that an athlete can successfully run on a treadmill set to specific running speeds and difficulties of inclines. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS. A non-linear formula for determining the maximum heart rate can be used here: Oakland. Most women (85%) and men (95%) completed the first stage, whereas only 32% of women and 64% of men completed the second stage. Protocol for Maximal Graded Exercise Stress Test Requirements If a plain GXT is required and is uninterpretable for any reason, a radionuclide GXT will then be required before further consideration GXT requirements: o 100% of predicted maximal heart rate unless medically contraindicated or prevented either by symptoms or medications Walking speed constant at 3 km/hr whilst the grade was increased by 2.5 percent every two minutes. There are Bruce protocol tables available for maximal (competitive athletes) and sub-maximal (non-athletic people) efforts[citation needed] (see below).

We avoid using tertiary references. After 3 minutes, the grade increases to 12% and the speed to 2.5mph. government site. In the last 30 seconds of each stage, record HR, oxygen saturation and BORG rate of perceived exertion . Pt achieved 17.2 METs, max heart rate is 220 minus your age METs mean on a treadmill gradient. The 10 minute period does not have to be exact; it is not actually what the test is determined by, but instead it is recommended simply as a way to prepare an individuals muscles for the rest of the test.
