Treadmill

Exercise is commonly known to improve physical fitness and health. The muscular and cardiovascular benefits of exercise are firmly documented. Exercise treadmills are widely used for performing walking or running aerobic-type exercise while the user remains in a relatively stationary position. In addition exercise treadmills are used for diagnostic and therapeutic purposes. Treadmills provide the advantage that they make it possible to do running exercises indoors, whereby the user is independent of weather conditions and large hall space. Treadmills offer aerobic and anaerobic exercise in a limited space, without regard to access to running or walking areas any greater than the space occupied by the treadmill. In addition, the advantage of treadmills when used for keeping fit is that they make it possible to combine exercises with some other activity which in a way allows for more time for the fitness exercise, because it can be combined with some other activity, such as watching a specific television program. A treadmill is a piece of exercise equipment that simulates the action of walking or running while allowing the user to remain essentially in one place. Typical treadmills offer slope adjustment, speed adjustment, heart rate counters, mileage meters, timers, and various other well known feedback displays and recording devices. Typical modern treadmills also offer route choices, which can take a user through simulated courses of hill and dale or various other predetermined runs/walks. Typical treadmills comprise a treadmill deck supported in a base frame or treadmill base, and an endless belt engaged around the treadmill deck for supporting users. A spring structure may further be provided and disposed between the treadmill base and the treadmill deck for providing resiliency or a cushioning effect to the users. A treadmill is classified into two types, namely fixed table and adjustable table. The fixed table treadmill has a table with a constant slope and the adjustable table treadmill can adjust the slope of the table. The adjustable table treadmill usually is provided with a control apparatus to be manipulative to change the slope of the table.
