Treadmills were historically used as a method of reforming offenders in
prison, an innovation introduced by Sir William Cubitt in 1817.; these
were also termed treadwheels. The first private health club in the U.S.
was started by Professor Louis Attila in 1894. Cardio workout machines
entered the clubs much later and were developed initially for the
hospital. The first medical treadmill designed to diagnose heart and lung
disease was invented by Dr. Robert Bruce and Wayne Quinton
at the University of Washington in 1952. Dr. Kenneth Cooper's research on
the benefits of aerobic exercise, published in 1968, provided a medical
argument to support the commercial development of the home treadmill and
Robert Arthur Bruce
Robert Arthur Bruce was an internationally
recognized cardiologist and a professor at the University of Washington.
Because of the nature of his research and his development of the Bruce
Protocol for exercise testing of cardiac patients, he was known as the
"father of exercise cardiology".
Before the development of the Bruce Protocol there
was no safe, standardized protocol that could be used to monitor cardiac
function in exercising patients. Master's Two-Step Test was sometimes
used, but it was too strenuous for many patients, and inadequate for the
assessment of respiratory and circulatory function during varying amounts
of exercise. Most physicians relied upon patients' complaints about
exertion, and examined them only at rest.
To address these problems, Dr. Bruce and Dr. Paul Yu began work on
developing a treadmill exercise test. The test made extensive use of
relatively new technological developments in electrocardiographs and
A Bruce exercise test involved walking on a treadmill while the heart was
monitored by an electrocardiograph with various electrodes attached to the
body. Ventilation volumes and respiratory gas exchanges were also
monitored, before, during and after exercise. Because the treadmill speed
and inclination could be adjusted, this physical activity was tolerated by
Initial experiments involved a single-stage test, in which subjects walked
for 10 minutes on the treadmill at a fixed workload. Bruce's first paper
on treadmill exercise tests, published in 1949, analyzed minute-by-minute
changes in respiratory and circulatory function of normal adults and
patients with heart or lung ailments.
In 1950 Bruce joined the University of Washington, where he continued
research on the single-stage test, particularly as a predictor of the
success of surgery for valvular or congenital heart disease. Later he
developed the multistage test, consisting of several stages of
progressively greater workloads. It was this multistage test, a
description of which was first published in 1963, that became known as the
Bruce Protocol. In the initial paper, Bruce reported that the test could
detect signs of such conditions as angina pectoris, a previous heart
attack, or a ventricular aneurysm. Bruce his and colleagues also
demonstrated that exercise testing was useful in screening apparently
healthy people for early signs of coronary artery disease.
Other Treadmill Uses
As it is basically a conveyor belt, the treadmill can be used for
activities other than running. If horses are being tested (especially in
jockey racing) they will be put on a specially constructed treadmill.
Large treadmills can also accommodate cars.
