Treadmills vs. Running

A study by Elliot & Blanksby Rate investigated in Medicine and Science in Sports stride length and pace. The authors recorded no significant differences in stride length and stride rate between walking on the treadmill and outdoors in the execution of 3.3 to 4.8 meters per second. However, at higher speeds, reduced stride length, while voting step, and the length of time a leg on the floor increases.

Treadmills vs. bike, rowing machine andSteppers

A study by the Medical College of Wisconsin showed that treadmills offer the most efficient way to burn calories compared to other popular devices. Researchers asked eight male and five female young adults engaged in six different types of indoor exercise equipment, including a cross-country skiing simulator, a bicycle, rowing machine, and stepper. They compared energy expenditure at ratings of perceived exertion levels fairly easily, a little hard and hard, and found that the subjects exercised on the "fairly light" burned about 40 percent more calories per hour on the treadmill to the bike, the lowest energy compared.

Bike vs treadmill, Stairmaster, Elliptical

A study at the University of Wisconsin showed that heart rate and oxygen consumption levels from the use of a> Crosstrainer were virtually identical to those from which on a treadmill, and much higher than walking on a treadmill, a stationary bicycle or a stepper motor. This was despite similar rates of perceived exertion. But the impact forces in the feet closer to that of running on the treadmill (Evaluation of an elliptical trainer as compared to treadmill walking and running, stationary cycling and amplification, Medicine and Science in Sports andExercise, 1998) A similar study had similar results. Zenia & Hoffman, energy expenditure with indoor exercise machines, Journal of the American Medical Association, 1996.

Ellipticals Going "backwards" on an elliptical machine about 7% burns more calories than go forward. Kravitz & Wax, Metabolic response of elliptical exercise training, Medicine and Science in Sports and Exercise, 1998.
