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. The length of time on the treadmill is the test score and can be used to estimate the VO2 max value.The Bruce Protocol test is one of the simpler methods of estimating VO2 max.

During the Bruce Protocol Test, you will be working to exhaustion to see how long you can last on the treadmill as your speed and incline will increase every three minutes. Each stage below represents a three-minute interval. Stage 1 = 1.7 mph at 10% Grade.Bruce Protocol Stress Test The Bruce Test is commonly used treadmill exercise stress test. It was developed as a clinical test to evaluate patients with suspected coronary heart disease, though it can also be used to estimate cardiovascular fitness.

See also a general description of Exercise Stress Tests.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.According to the original Bruce protocol, the patient walks on an uphill treadmill in a graded exercise test with electrodes on the chest to monitor the EKG. Every 3 minutes, the speed and incline of the treadmill are increased. There are 7 such stages and only very fit athletes can complete all 7.Following the warm up period, the Bruce Treadmill Test actually starts.

To perform the test, an individual should start jogging on a treadmill set to a pace of 1.7mph and an incline of 10%. This is the first stage of the test and should be kept up for a total of 3 minutes. Every following stage of the test should also be kept for 3 minutes.

A Bruce exercise test involved walking on a treadmill while the heart was monitored by an electrocardiograph with various electrodes attached to the body. Ventilation volumes and respiratory gas exchanges were also monitored, before, during and after exercise.THE BRUCE SUBMAXIMAL TREADMILL TEST IS PERHAPS THE MOST common test used to assess cardiorespiratory fitness, especially in clinical settings. The test is administered in three-minute stages until the client achieves 85% of his or her age-predicted maximum heart rate (MHR).

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.

An inability to exercise >6 minutes on the Bruce protocol, or an inability to increase heart rate (HR) to >85% of maximum predicted heart rate (MPHR) are significant indicators of increased risk of coronary events with a 5-year survival ranging from 50% to 72%.It is worth emphasizing that in the most heavily trained athletes, a standard Bruce graded exercise protocol may not be sufficient and other more aggressive exercise studies may be needed. 27 More aggressive graded exercise protocols such as the Astrand and Astrand-Saltin are done at increased speed and incline to help accommodate the greater aerobic capacity of an athlete.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.

Record total running time.A variety of treadmill fitness and stress tests are available, but the commonly used treadmill ramp test is the Bruce protocol. It is the easiest to administer and is widely available in clinical and fitness locations. This is the amount of oxygen in milliliters your body can use per kilogram of body weight per minute.Participants were asked to complete two maximal treadmill running tests (using the Bruce and the Athlete-led protocol) to volitional failure in a randomised cross-over trial 1 week apart.

The participants were asked to refrain from intense exercise and alcohol for 24 h prior, and caffeine from 4 h prior to each main trial.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 (See chart). The length of time on the treadmill is the test score and can be used to estimate the VO2 max value.

Treadmill testing is another viable indoor option and includes tests such as the 1­mi (1.61­km) walk and the Bruce and Balke­Ware protocols, which gradually increase the metabolic equivalents (METs, representing the physiologic intensity level of exercise) that apply to the individual.
