The Bruce treadmill test is a maximal running test performed on a treadmill. 9 minutes 15 seconds = 9.25 minutes). The Bruce protocol is a maximal exercise test where the athlete works to complete exhaustion as the treadmill speed and incline is increased every three minutes. It was uncommon for women (3%) or men (15%) to complete the third stage. Your maximum heart rate is 185.7 bpm based on the Oakland non-linear formula. Begin treadmill walking and progress speed/grade as per Modified Bruce Protocol (Appendix 1) 5. Each subsequent stage has an increment of 0.7 to 0.8 mph in speed and 2% in gradient. If you get to the last stage, you'll be walking at 5.5 mph up a 20% grade. 100 % and 9 minutes on a treadmill that has reliable incline speed. The median was 10.8 years (6.5 and 15.8 years for the 25th and 75th percentiles, respectively), compris-ing a total of 208108 person-years. Blockages in the last stage, record a standard resting supine12 lead ECG years! The first 4 stages of the Bruce protocol are shown in real time. At each stage, the gradient and speed of the treadmill are elevated to increase work output, called METS. Breathing volumes and respiratory gas exchange were also monitored before, during and after exercise. Instead, this test is based on what its name suggestsperformance on a treadmill. Every following stage of the test should also be kept for 3 minutes. Stage 1 = 1.7 mph at 10% Grade. Calculations - unlimited. SYNOPSIS: A group of researchers delivered results that could help inform clinicians about the expected exercise test performance of older patients. For example, a 60-year-old woman whose exercise capacity was 7 MET on a Bruce-protocol exercise test would have achieved 100 percent of the predicted exercise capacity for her age. According to the American College of Cardiology, stress tests should only be performed on patients who have peripheral artery disease, diabetics over age 40 and people who have an increased risk of coronary artery disease. Heart rates vary from person to person, influenced by a variety of variables. The fist two stages of the Modified Bruce Test are performed at a 1.7 mph and 0% grade and 1.7 mph and 5% grade, and the third stage corresponds to the first stage of the Standard Bruce Test protocol as listed above. results: The test score is the time taken on the test, in minutes.

What is a good METs score for a stress test? Bruce test is considered a maximal exercise test where the athlete or client runs to complete fatigue as the treadmill speed and incline are increased every three minutes.
