What is the Balke treadmill protocol?
procedure: The athlete walks on a treadmill to exhaustion, at a constant walking speed while gradient/slope is increased every one or two minutes. The assistant starts the stopwatch at the beginning of the test and stops it when the subject is unable to continue.
What does the Balke treadmill test measure?
The Balke Treadmill test is an effective way to measure your VO2 max. VO2 max is considered the best measure of an athletes cardio endurance, an essential part of all sports that require endurance.
What is the correct protocol for the Bruce treadmill test?
Procedure. Exercise is performed on a treadmill. The leads of the Ecg are placed on the chest wall. The treadmill is started at 2.74km/hr (1.7mph) & at an inclined gradient of 10% After 3 min incline of the treadmill is increased by 2%, and the speed increases .
How do you calculate VO2 Max from Balke protocol?
With the Balke test the grade is changed every minute with a constant speed until the subject can no longer perform. The final time is recorded and then put into an equation to estimate VO2 max. The equation for the Balke test is VO2max= 1.444(time)+14.99 for men and VO2max=1.38(time)+5.22 for women.
Is the Bruce protocol accurate?
Data gathered from each protocol demonstrated that the usage of the ramped Bruce protocol achieved more consistent results in comparison across all BMI groups in achieving 80%–85% of their age-predicted maximum heart rate.
How long is the Bruce protocol?
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.
What is Stage 3 Bruce protocol?
Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased. 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.
What can the Balke Treadmill protocol be used for?
View Full Profile. Fact Checked. The Balke treadmill protocol can be used to estimate cardiovascular condition and endurance by measuring maximum oxygen uptake, known as V02max. You can undergo this fitness test at a slow pace, making it suitable for cardiac patients as well as healthy people.
What should the speed be on the Balke treadmill?
The Balke Protocol. Start the timer when you are ready to begin the test. Use a constant speed of 3.3 mph if you are a man and 3.0 mph if you are a woman.
What is the Balke treadmill VO 2 test?
The Balke Treadmill Test was developed as a clinical test to determine peak VO 2 in cardiac patients, though it can also be used to estimate cardiovascular fitness in athletes.
When do you stop the treadmill Balke test?
The assistant starts the stopwatch at the beginning of the test and stops it when the subject is unable to continue. There are several modification or variation of the Balke test that are used, with variations in the treadmill speed, time at each level and/or increase in gradient. Here are examples of test protocols that have been used.
