Example of modern treadmill

A treadmill is a device mostly used for walking, running, or climbing while staying in the aforementioned identify. 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. In later times, treadmills were used as penalization devices for people sentenced to difficult labor in prisons. The terms treadmill and treadwheel were used interchangeably for the ability and penalization mechanisms.

More recently, treadmills have instead been used as exercise machines for running or walking in one identify. Rather than the user powering a manufactory, the device provides a moving platform with a wide conveyor belt driven by an electric motor or a flywheel. The belt moves to the rear, requiring the user to walk or run at a speed matching the belt. The rate at which the belt moves is the charge per unit of walking or running. Thus, the speed of running may be controlled and measured. The more expensive, heavy-duty versions are motor-driven (usually by an electric motor). The simpler, lighter, and less expensive versions passively resist the motion, moving only when walkers push the chugalug with their anxiety. The latter are known as transmission treadmills.

Treadmills continue to be the biggest selling practice equipment category past a big margin. As a result, the treadmill industry has hundreds of manufacturers throughout the world.^[1]

History [edit]

William Staub, a mechanical engineer, developed the starting time consumer treadmill for home use.^[2] Staub developed his treadmill subsequently reading the 1968 book, Aerobics by Kenneth H. Cooper. Cooper'south book noted that individuals who ran for eight minutes four to five times a week would exist in better concrete status. Staub noticed that at that place were no affordable household treadmills at the fourth dimension and decided to develop 1 for his own apply during the belatedly 1960s. He called his first treadmill the PaceMaster 600. One time finished, Staub sent his prototype treadmill to Cooper, who found the auto's first customers, including sellers of fitness equipment.

Staub began producing the first home treadmills at his plant in Clifton, New Bailiwick of jersey, before moving product to Little Falls, New Jersey.

Treadmills for ability [edit]

Human-powered treadmill for grinding grain

Treadmills equally power sources originated in antiquity.^[3] These aboriginal machines had three major types of pattern.^[four] The first was a horizontal bar jutting out of a vertical shaft. Information technology rotated around a vertical axis, driven past an ox or other animal walking in a circumvolve and pushing the bar. Humans were also used to power these. The second design was a vertical cycle, a treadwheel, that was powered by climbing in place instead of walking in circles. This is similar to what we know today equally the hamster cycle. The third design likewise required climbing but used a sloped, moving platform instead.

Treadmills equally muscle powered engines originated roughly 4000 years ago.^{[ citation needed ]} Their main apply was to lift buckets of h2o. This same technology was afterwards adapted to create rotary grain mills and the treadwheel crane. It was also used to pump water and power dough-kneading machines and bellows.

Treadmills for punishment [edit]

Treadmill used to punish prisoners at Breakwater Prison, Greatcoat Town

Treadmills for punishment were introduced in 1818 by an English engineer named Sir William Cubitt, who was the son of a miller. Noting idle prisoners at Bury St Edmunds gaol, he proposed using their muscle power to both cure their idleness and produce useful work.^[5]

Cubitt's treadmills for punishment commonly rotated around a horizontal axis, requiring the user to step up, like walking up an endless staircase. Those punished walked effectually the outside of the wheel holding a horizontal handrail for stability. By the Prison house Act of 1865 every male prisoner over 16, sentenced to hard labour, had to spend three months at least of his judgement in labour of the kickoff grade, which consisted primarily of the treadmill.^{[half dozen]}

Penalty treadmills remained in employ until the second half of the 19th century; they were typically twenty-foot long paddle wheels with xx-four steps around a six-pes cylinder. Several prisoners stood side-by-side on a bicycle, and had to work six or more hours a day, effectively climbing 5,000 to fourteen,000 vertical feet (ane,500 to 4,000 m). While the purpose was mainly castigating, the nearly infamous mill at Brixton Prison was installed in 1821 and used to grind grain to supplement an existing windmill which Cubitt had previously installed nearby. Information technology gained notoriety for the cruelty with which it was used, which and so became a pop satirical metaphor for early-19th century prisons.

The machines could also be used to pump water or ability ventilators in mines.^{[7] [8]}

Practice treadmills [edit]

The start US patent for a treadmill "training machine" (#ane,064,968) was issued on June 17, 1913.^[9]

The forerunner of the do treadmill was designed to diagnose heart and lung diseases, and was invented by Robert Bruce and Wayne Quinton at the University of Washington in 1952.^[10] Kenneth H. Cooper'southward research on the benefits of aerobic exercise, published in 1968, provided a medical argument to support the commercial development of the home treadmill and practise wheel.

Among users of treadmills today are medical facilities (hospitals, rehabilitation centers, medical and physiotherapy clinics, institutes of higher education), sports clubs, biomechanics institutes, orthopedic shoe shops, running shops, Olympic preparation centers, universities, burn-training centers, NASA, test facilities, police forces and armies, gyms and even habitation users.

Treadmill ergometers are now mainly motor driven. Near treadmills have a running deck with a rotating belt. Before and after the running deck, there are two shafts. The chugalug is stretched between the shafts and the running deck. Safety standards for treadmills are IEC EN 957-one and IEC EN 957-6.

For medical treadmills applicable norms, standards and guidelines include the Medical Device Directive (MDD), European Guideline 93/42 EEC, European Guideline 2007/47 EEC, IEC EN 60601-one, EN 62304, EN 14971 and the machinery directive 2006/42/EC.

Medical treadmills are class IIb active therapeutic devices and also agile devices for diagnosis. With their very powerful (e.k. 3.iii kW = 4.five HP) electrical motor powered drive system, treadmills deliver mechanical energy to the human body through the moving running belt of the treadmill. The subject does non change their horizontal position and is passively moved and forced to grab up with the running chugalug underneath their feet. The subject tin likewise be attached in a condom harness, unweighting arrangement, diverse supports or even fixed in and moved with a robotic orthotic system utilizing the treadmill.

Medical treadmills are also active measuring devices. When connected through an interface with ECG, ergospirometry, blood pressure monitor (BPM), or EMG, they become a new medical system (e.g., stress exam system or cardiopulmonary rehabilitation system) and can also be equipped to measure VO₂ max and various other vital functions.

Nearly treadmills have a "cardio mode", where a target heart rate is defined and the speed and elevation (load) is controlled automatically until the subject area is in "heart rate steady country". So the treadmill is delivering mechanical energy to the human torso based on the vital office (eye rate) of the subject.

A medical treadmill which is too used for ergometry and cardiopulmonary stress examination likewise as functioning diagnostics is always a grade IIb medical device either when used equally stand-alone device in a medical environment or when used in connection with an ECG, EMG, ergospirometry, or blood pressure monitoring device.

On the running deck the subject field moves, adapting to the adjustable speed of the belt. The running deck is normally mounted on damping elements, and so the running deck has daze absorbing characteristics. A lifting chemical element raises the entire frame including the running deck, and simulating a pitch angle for uphill running. Some treadmills can also reverse the running chugalug to simulate downhill loads. Most treadmills for professional use in the fitness expanse have table sizes of about 150 cm (59 in) long and fifty cm (twenty in) width, a speed range of about 0–twenty km/h (0–12 mph) and slope angle of 0-xx%.

For athletes, larger and more than stable treadmills are necessary. With some weight relief, sprinters reach temporary speeds of upwardly to 45 km/h (28 mph) and must therefore run on a large deck of up to 300 cm (120 in) in length and up to 100 cm (39 in) in width. With high concrete exertion and an increased take a chance of falling, a autumn stop unit is required to foreclose the subject or patient from falling. This fall terminate device usually takes the form of a safety arch to which a line is attached to an electrical switch. A harness bears the subject, preventing them from falling and shutting downward the running belt if necessary.

In some offices, employees are provided with treadmill desks so that employees can walk while working on a computer or speaking on the phone.^[11]

In treatment centers, treadmills are used with built-in seats left and correct for therapists, for example, so the therapists can motility the legs of a stroke patient in order to simulate walking movements and aid them learn to walk over again. This is called transmission locomotion therapy.

Oversized treadmills are also used for cycling at speeds up to 80 km/h (50 mph), for wheelchair users and in special applications with sturdy running belts for cross-state skiing and biathlon, where athletes perform training and testing exercises with roller skis on a running deck of upwards to 450 cm × 300 cm (180 in × 120 in).

Advantages [edit]

• Enable the user to adhere to an indoor practice regime irrespective of the conditions.
• Cushioned tread can provide slightly lower touch training than running on outdoor surfaces. Although cushioned belts accept mostly been phased out and cushioned replacement belts may be hard to find, many treadmills have safety or urethane deck elastomers (cushions) which are superior in cushioning and concluding longer than cushioned belts. For a time, assistant shaped flexible decks were available which were among the very all-time for cushioning and were priced at a mid-range level, but these are no longer being sold, perhaps because of the increased manufacturing toll of making flexible decks. Cushioned belts do not last as long as regular belts due to their construction from weaker materials. For calorie called-for, incline can be used to significantly reduce affect for a given rate of free energy use.
• Incline setting tin can allow for consistent "uphill" preparation that is not possible when relying on natural features.
• Rate settings force a consistent pace.
• Some treadmills have programmes so that the user can simulate terrains, e.g. rolling hills, to provide accurate, programmed, practice periods.
• The user can watch Telly whilst using the machine, thus preventing Telly watching from existence a sedentary activity.
• User progress such equally altitude, calories burned, and heart rate tin can be tracked.^{[ citation needed ]}

Disadvantages [edit]

Every bit a cardiovascular practice:

• Some treadmill runners develop poor running habits that become apparent when they return to outdoor running. In particular a brusque, upright, bouncy gait may result from having no wind resistance and trying to avoid kicking the motor roofing with the front of the foot.
• Imposes a strict step on runners, giving an unnatural experience to running which can crusade a runner to lose balance.
• Treadmill running is not specific to any sport, i.e., there is no competitive sport that actually utilizes treadmill running. For example, a competitive runner would be far meliorate off running outdoors through space since it is more than specific and realistic to their event.
• There are differences in temporal and athwart kinematics which should exist considered when treadmills are used within a rehabilitation program.^[12]

As an indoor action:

• Many users find treadmills monotonous and lose interest subsequently a catamenia.^[thirteen]
• Treadmills practice non offering the psychological satisfaction some runners get from running in new locations away from the distractions of home.

As a auto:

• May cause personal injury if not used properly. Of particular concern are children who reach into the treadmill belt while information technology is running and suffer astringent friction burns that in the worst case may crave multiple skin grafts and outcome in lasting inability.^[fourteen] Injury to children can be avoided by removing the condom key when the treadmill is not in apply, without which, the treadmill chugalug will not commencement.
• Costs of purchase, electrical costs, and possible repair are significantly greater than those of running outside.
• Takes upwardly space in homes.

Treadmill maintenance [edit]

A treadmill can lose its speed and functioning if not maintained from time to time. Starting from positioning of the treadmill to regular oil checks, a treadmill's longevity is determined by how it is maintained.

Placement [edit]

Ideally, a treadmill should be placed on a leveled floor in order to ensure the belt and motor accept a proper balanced movement. In instance of uneven floors, the elevation of either of the legs (rear or front legs) should be leveled out using a forest block or a brick.

Cleaning [edit]

Dirt that gets accumulated on a treadmill can also crusade malfunction. Dirt on the belt or the deck is cleared by wiping the belt and the sides of the treadmill in one case or twice a month using a fabric or a wet sponge.

Chugalug maintenance [edit]

The conveyor belt is an important function that is responsible for the operation of the treadmill. Regular maintenance for the belt includes

1. Lubrication
2. Alignment
3. Tension Maintenance

Other uses [edit]

As it is basically a conveyor belt, the treadmill tin be used for activities other than running. If horses are existence tested (particularly in jockey racing) they will exist put on a specially synthetic treadmill. Large treadmills can also accommodate cars. Treadmills tin besides be used to exercise dogs that are accepted to running on a conveyor; all the same, tying the leash to the treadmill should be avoided as it can cause serious injury.

Underwater treadmill [edit]

Underwater treadmills are a type of treadmill encased in drinking glass or plastic and filled with water to a point where the occupant is partially submerged. They are used for both humans and animals, often for physical therapy.^[15]

Dog/pet and underwater pet treatment treadmills are available for both habitation and clinical employ. A variety of makes and models are bachelor, but key features of treadmills designed for pet use include a longer running surface, open front and back entries and side runway to forestall the pet from falling off the treadmill. None are designed to exist used without human supervision. Many veterinary and animal rehabilitation clinics also offer underwater treadmill therapy as function of their services provided to clients' pets.

Omnidirectional treadmill [edit]

Advanced applications are so chosen omnidirectional treadmills. They are designed to move in ii dimensions and are intended as the base for a "holodeck". Several solutions have been proposed, but inquiry continues equally some issues remain unsolved, such as big size, noise and vibration. Parallel developments are being conducted past researchers working on projects sponsored by the U.s.a. Department of Veterans Affairs to create virtual reality environments for a wheelchair trainer in order to promote therapeutic practise.^[16]
