The Harvard step test, in scientific literature sometimes referred to as the Brouha Test, is a type of cardiac stress test for detecting and diagnosing cardiovascular disease. It is also a good measurement of fitness and a person's ability to recover after a strenuous exercise by checking the recovery rate. The test was developed by Lucien Brouha and his associates in 1942.[1][2]
The test subject repeatedly steps onto and off of a platform in a cycle of two seconds.[a] The height of the platform is 20 inches or 51 centimetres for men and 16 inches or 41 centimetres for women. The rate of 30 steps per minute must be sustained for five minutes or until exhaustion. To ensure the right speed, a metronome is used. Exhaustion is the point at which the subject cannot maintain the stepping rate for 15 seconds. The subject immediately sits down on completion of the test, and the heartbeats are counted for 1 to 1.5, 2 to 2.5, and 3 to 3.5 minutes.[2]
The results are written down as time until exhaustion in seconds () and total heartbeats counted (). It is plotted into a simple fitness index equation:[2]
The outcome of the equation is rated as follows:[4]
^"At the signal up, the subject places one foot on the platform, steps up placing both feet fully on the platform, straightens his legs and back and immediately steps down again, one foot at a time."[3]
