The historical word for the treadmill is treadwheel. The treadmill is completely known as the device that the user is using for either walking or running while the user is basically staying in the same place. The treadmills have been introduced to the public long before there was a possibility for developing anything of the powered machines. This development were made to harness the power of either animal or humans to do the work. It was very often for the type of the mill that was once operated by either a person or animal that is treading the steps of a treadwheel in other to grind the grain. However, the historical development made it possible for the treadmill to be used as a device that make punishment possible. This punishments were for people that have been sentenced to prisons with hard labor.
This make it possible for the prisoners to have good cardio conditions when they get out of prison. However, this has never stop the users from having the device for personal use, which make workout more comfortable. The treadmill has a lot of things that it can easily offer to the people that are using the device for workout. The understanding of the treadmill and treadmill as a term contributed to the usage in the interchangeable for both the power and the punishment mechanisms. The long history behind the treadmills make it possible for the innovative companies to consider using the machine for other purposes. This has contributed to the more recent treadmills to not be used for harnessing the power, but to be used as the exercise machine that have the ability to let its user to do both running and walking in the same place. It used to be possible for the user to power the mill by him or her. However, the machines are now providing a moving platform that also entail a wide conveyor belt driven, which is done by either the electric motor or even a flywheel.
The belt itself is always moving to the rear. However, it also highly require the user of the device to either walk or run at the speed that is corresponding with the speed of the belt itself. The same rate that the belt moves is the same rate of either walking or running. The speed of the belt can easily be both controlled and measured. The treadmills that are more pricy, and heavy duty versions are the ones that are driven by a motor, which is usually electric. However, the ones that are lighter, simpler and less expensive versions are known to be passive in resisting motion, and move only when the user is pushing the belt with his or her feet. This are the ones known as the manual treadmills.
