Harvard Step Test
The Harvard Step test is a test of aerobic fitness, developed by Brouha et al. (1943) in the Harvard Fatigue Laboratories during WWII. The features of this test is that it is simple to conduct and requires minimal equipment. There are many other variations of step tests too.
- equipment required: step or platform 20 inches / 50.8 cm high, stopwatch, metronome or cadence tape.
- procedure: The athlete steps up and down on the platform at a rate of 30 steps per minute (every two seconds) for 5 minutes or until exhaustion. Exhaustion is defined as when the athlete cannot maintain the stepping rate for 15 seconds. The athlete immediately sits down on completion of the test, and the total number of heart beats are counted between 1 to 1.5 minutes after finishing (see measuring heart rate). This is the only measure required if using the short form of the test. If the long form of the test is being conducted, there is an additional heart rate measures at between 2 to 2.5 minutes, and between 3 to 3.5 minutes. See some videos of Harvard Step tests being performed.
- scoring: the Fitness Index score is determined by the following
equations. For example,
if the total test time was 300 seconds (if completed the whole
5 minutes), and the number of heart beats between 1-1.5 minutes
was 90, between 2-2.5 it was 80 and between 3-3.5 it was 70,
then the long form Fitness Index score would be: (100 x 300) / (240 x 2) = 62.5. Note: you are using the total number of heart beats in the 30 second period, not the rate (beats per minute) during that time.
Fitness Index (short form) = (100 x test duration in seconds) divided by (5.5 x pulse count between 1 and 1.5 minutes).
Fitness Index (long form) = (100 x test duration in seconds) divided by (2 x sum of heart beats in the recovery periods).
rating fitness index
(long form)excellent > 96 good 83 - 96 average 68 - 82 low average 54 - 67 poor < 54 (norms from: Fox et al. 1973) - validity: correlation to VO2max has been reported as between 0.6 to 0.8 in numerous studies.
- advantages: This test requires minimal equipment and costs, and can be self-administered.
- disadvantages: Biomechanical characteristics vary between individuals. For example, considering that the step height is standard, taller people are at an advantage as it will take less energy to step up onto the step. Body weight has also been shown to be a factor. Testing large groups with this test will be time consuming.
- comments: The Harvard Step Test was developed by Brouha et al. (1943) in the Harvard Fatigue Laboratories during WWII. Some sources suggest a 40 cm high bench, which is not the standard and original bench height. Since the original description of this test, there have been variations in the test procedure such as reducing the bench height for female subjects in some research studies. Also be aware that I have noticed that some websites incorrectly list the formula for the long form without doubling the denominator. What is listed here has been confirmed as the correct formula.
