How are calories calculated on Precor equipment?

Precor equipment calculate caloric consumption from a proprietary algorithm based on an average profile developed in conjunction with the American College of Sports Medicine. A number of variables determine the formula, including weight, speed, incline setting and torque. Since people burn calories at different rates, it is impossible to create absolutely accurate calorie burn rates without using sophisticated and sensitive monitoring equipment. Therefore, the calorie burn rate shown on the console fits an average profile. The actual accuracy of the results depends on how close you are to the average profile. These results should be used as a benchmark and not as an absolute measurement.
