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.
