The Bruce Protocol Treadmill stress Test / Vo2 max calculator can be used to calculate approximate Vo2 max which is a measure of cardiovascular fitness , expressed in mL O2 consumed/kg body weight/minute. This method has 10 stages, with each stage lasting 3 minutes and increasing both speed and slope with each successive stage. The bruce protocol stress test or the Bruce Treadmill test protocol was first designed in 1963, by Robert A. Bruce. Bruce protocol stress test was a non-invasive stress test to assess patients with probable or suspected weak heart conditions. Other than a stress test it is also called as the exercise tolerance test. How to Do the Bruce Protocol. Start the treadmill at 1.7 miles per hour with a 10 percent elevation. (This should be an easy walking warm-up speed.) After exactly three minutes, increase the speed to 2.5 miles per hour and the elevation to 12 percent. Continue to increase the settings every three minutes. Test protocol and administration: • This treadmill tests begins at 1.7 mph and a 10% incline. • Assess and record exercise HR and RPE at each minute; assess and record exercise BP at the 2:15 mark of each stage. • The stages for the Bruce submaximal treadmill test progress are shown in the table below. • Each stage is three minutes in duration.
2 Mar 2015 Treadmill test predicts your chance of dying in the next ten years by 'METs'; Scientists say the test is more useful than existing stress exams. modified Bruce protocol) with incremental treadmill Absolute contraindications for exercise stress test- Exercise stress testing has a lower diagnostic value.
An exercise stress test is a good — but not great — indicator of the health of the heart and coronary arteries. It works quite well for people who are likely to have cholesterol-clogged arteries and who can exercise long enough to reach their maximum heart rate. In a clinical setting, the Bruce treadmill test protocol is sometimes called a stress test or exercise tolerance test. The test can be used to estimate maximal oxygen uptake , which is a measure of an athlete's capacity to performed sustained exercise. It is linked to aerobic endurance. 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. The Bruce Protocol Treadmill stress Test / Vo2 max calculator can be used to calculate approximate Vo2 max which is a measure of cardiovascular fitness , expressed in mL O2 consumed/kg body weight/minute. This method has 10 stages, with each stage lasting 3 minutes and increasing both speed
Stress testing: A contribution from Dr Robert A. Bruce, father of exercise cardiology. step exercise test, which involves obtaining an electrocardiogram (ECG) after a patient has repeatedly climbed up onto and down from a small platform, 3,4 a test that can be too strenuous for some patients. The Bruce treadmill test is a maximal running test performed on a treadmill. It is one of the most commonly used tests in USA. Instructions: 1. You need a treadmill that has reliable incline and speed possibilities. 2. Follow the protocol described below. (printer friendly pdf-shee The modified Bruce protocol has 2 warmup stages, each lasting 3 minutes. The first is at 1.7 mph and a 0% grade, and the second is at 1.7 mph and a 5% grade. This protocol it is most often used in older individuals or those whose exercise capacity is limited by cardiac disease. All subjects underwent exercise treadmill stress with electrocardiographic monitoring using standard exercise protocols; 1,033 of 1,056 (99%) exercised according to a Bruce or modified Bruce protocol. The decision of whether to stop anti-ischemic medication prior to testing was left up to the discretion of the referring physician. The exercise ECG indirectly detects myocardial ischemia, which is the physiologic consequence of a mismatch between myocardial oxygen delivery (coronary blood flow) and myocardial oxygen demand (myocardial work).
