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.
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 ...
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
Once improvement in aerobic conditioning is apparent, for example in metabolism and oxygen uptake, the body progressively adapts to further training. [20] Aerobic conditioning can be anywhere from walking on the treadmill to mowing the lawn. The average healthy person should engage in 150–200 minutes of moderate aerobic exercise every week.
In Fick's original method, the "organ" was the entire human body and the marker substance was oxygen. The first published mention was in conference proceedings from July 9, 1870 from a lecture he gave at that conference; [ 1 ] it is this publishing that is most often used by articles to cite Fick's contribution.The principle may be applied in ...

An indoor rower, or rowing machine, is a machine used to simulate the action of watercraft rowing for the purpose of exercise or training for rowing.Modern indoor rowers are known as ergometers (colloquially erg or ergo) because they measure work performed by the rower (that can be measured in ergs).
