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.{{cite journal |last1=Brouha |first1=Lucien |author-link1=Lucien Brouha |last2=Heath |first2=Clark W. |last3=Graybiel |first3=Ashton |author-link3= |date=1943 |title=The step test: a simple method of measuring physical fitness for hard muscular work in adult men |journal=Revue Canadienne de Biologie |volume=2 |issue=1 |pages=86–91 |issn=0035-0915}}{{Cite journal |last=Brouha |first=Lucien |date=1943 |title=The Step Test: A Simple Method of Measuring Physical Fitness for Muscular Work in Young Men |url=https://www.tandfonline.com/doi/full/10.1080/10671188.1943.10621204 |journal=Research Quarterly.

Procedure

The test subject repeatedly steps onto and off of a platform every two seconds. The height of the platform is {{convert|20|in|cm|disp=or}} for men and {{convert|16|in|cm|disp=or}} 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.

The results are written down as time until exhaustion in seconds (t_e) and total heartbeats counted (h_b). It is plotted into a simple fitness index equation:

: \frac{t_e * 100}{h_b * 2}

The outcome of the equation is rated as follows:{{cite web | first=Robert |last=Wood |url= http://www.topendsports.com/testing/tests/step-harvard.htm |publisher=Topend Sports Website |title=Harvard Step Test |date=2008 |access-date=1 September 2021}}

Modified versions

The test was developed at Harvard University in 1942. Several modified versions of the original Harvard step test exist; examples include the Tecumseh step test and the Kasch step test.{{cite journal |last1=Kasch |first1=Fred |last2=Phillips |first2=WH |last3=Ross |first3=WD |last4=Carter |first4=JE |url= https://www.ncbi.nlm.nih.gov/pubmed/14330411/ |title=A Step Test for Inducing Maximal Work |journal=J Assoc Phys Ment Rehabil |volume=19 |pages=84–86 |date=May–Jun 1965 |pmid=14330411}} Another modified version, the Sharkey step test, was developed in the 1970s for use by the United States Forest Service at the University of Montana in Missoula.
