ABSTRACT

Work and power can be calculated for a participant cycling on the cycle ergometer by using the number of flywheel revolutions per minute, the distance the flywheel travels per revolution and the resistance applied to the flywheel usually from weights hung from the flywheel belt. The most commonly used cycle ergometer is the Monark, which has a known flywheel movement of 6 m per revolution. The Tunturi moves 3 m per revolution. Work can be calculated for a participant moving on a treadmill by knowing the participant's body weight, and the percentage grade and speed at which the participant is moving. These values allow for the calculation of vertical displacement of the body during movement. Calculation of work performed during horizontal movement is complicated because the vertical displacement of the body is not easy to measure.
