Oxygen consumption and speed of cycling using an air-resistance simulator on a hometrainer roller

Oxygen consumption was determined for subjects cycling on a hometrainer roller with a racing bicycle. In part of the experiments the bicycle was supplied with an air-resistance simulator. The relation between oxygen consumption and velocity of cycling on the roller is linear: similar to that during bicycle ergometry. The relation is almost the same as during bicycling outdoors on a touring bicycle when the simulator is used while cycling on the roller. Cycling with the simulator only on the bicycle on a support is comparable to cycling outdoors on a racing bicycle. It is concluded that the use of a roller and an air-resistance simulator can be used for ergometry and training.
