Example of modern treadmill. A treadmill is a device generally used for walking, running, or climbing while staying in the same place.Treadmills were introduced before the development of powered machines to harness the power of animals or humans to do work, often a type of mill operated by a person or animal treading the steps of a treadwheel to grind grain.
William Edward Staub (November 3, 1915 – July 19, 2012) was an American mechanical engineer who invented and developed the first consumer treadmill for home use, the PaceMaster 600, during the late 1960s.

Although the Drinker model was effective and saved lives, its widespread use was hindered by the fact that the machines were very large, heavy (about 750 lbs or 340 kg), bulky, and expensive. An adult machine cost about $2,000 in the US in 1930 (equivalent to $36,000 in 2023), and about £1,500 sterling in Europe in the mid-1950s (equivalent to ...
The modified Bruce Protocol is an alteration in the protocol so that the treadmill is initially horizontal rather than uphill, with the 1st few intervals increasing the treadmill slope only. [3] The Bruce treadmill test estimates maximum oxygen uptake using a formula and the performance of the subject on a treadmill as the workload is increased ...
An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
Whether you choose to purchase or use an elliptical machine or treadmill, cross-training with the opposite equipment is often a good idea. This is because the two types of machines offer benefits ...
An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. They are also used industrially and as medical devices for oxygen therapy. [58] Two methods in common use are pressure swing adsorption and membrane gas ...
