Treadmill Bike

Abstract

A treadmill machine is used for walking or running. 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 that was operated by a person or animal treading steps of a tread wheel to grind grain. In later times, treadmills were used as punishment devices for people sentenced to hard labour in prisons. The terms treadmill and tread wheel were used interchangeably for the power and punishment mechanisms. Recently, treadmills are not used to harness power generation, but it use as an exercise machine for running or walking in one place. Rather than the user powering the mill, the machine provides a moving platform with a wide conveyor belt driven by an electric motor or a flywheel. When a user walks on the belt it moves to the rear. he rate at which belt moves is same as user walking or running. So that the speed of running and walking may be controlled and measured. The more expensive, heavy-duty versions are motor-driven (usually by an electric motor). The latter is known as manual treadmills. The treadmill is a largest selling exercise equipment According to Sports & Fitness Industry Association. So the treadmill industry counts with hundreds of manufacturers throughout the World.
