Balke Treadmill Test

The Balke Treadmill Test is a clinical test initially developed to determine peak VO2 in cardiac patients. However, it can also be used to estimate cardiovascular fitness in athletes. This test involves walking on a treadmill to exhaustion while the gradient/slope is increased every one or two minutes. It is important to note that there is another field test developed by Balke, known as the 15-minute run test, as well as the Balke Step Test.

Purpose

The purpose of the Balke Treadmill Test is to determine peak VO2, particularly in cardiac patients.

Equipment Required

To perform this test, you will need a treadmill, a stopwatch, and an electrocardiograph (optional).

Pre-Test

Before conducting the test, it is essential to explain the procedures to the subject and perform a screening of health risks. Obtain informed consent and record basic information such as age, height, body weight, gender, and test conditions. Prepare the necessary forms and measure out the course, placing marker cones. Lastly, ensure that the subject performs an appropriate warm-up.

Procedure

During the test, the athlete walks on a treadmill at a constant speed while the 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. There are variations of the Balke test that involve different treadmill speeds, time at each level, and/or increases in gradient.

Results

The test score is the time taken to complete the test, measured in minutes. Ideally, the test should take between 9-15 minutes. The test time can also be used to calculate an estimated VO2max score using specific formulas for men and women.

For men: VO2max = 1.444(T) + 14.99 [Pollock et al., 1976]
For women: VO2max = 1.38(T) + 5.22 [Pollock et al., 1982]

Target Population

The Balke test is recommended for cardiac patients due to its moderate elevation in workload, making it considered safe even for patients with severe left ventricular dysfunction.

Advantages

One advantage of the Balke Treadmill Test is that it provides a measurement of maximum heart rate, which can be useful in setting workload intensity for training programs.

Disadvantages

There are a few drawbacks to this test. It takes a relatively long time to set up and conduct compared to other aerobic tests. Additionally, there are high costs involved in terms of equipment and time.

Caution

It is important to note that the Balke Treadmill Test is a maximal test. If it is being used with recreational athletes, people with health problems, injuries, or low fitness levels, medical assistance should be available.
