摘要：

When a subject is required to exercise while sitting in a whole-body calorimeter, special arrangements must be made with respect to the ergometer. From a human energy balance point of view, only the energy liberated inside the body is of interest; all mechanical work done on the braking mechanism in concentric work should be dissipated as heat outside the calorimeter. This is critical in eccentric work, because an eccentric work ergometer requires a powerful electric motor; it would be unrealistic to mount such an ergometer inside the calorimeter. The obvious solution is to install a pedestal with pedals in the calorimeter on which the subject can pedal, and to connect the pedals through axles, mitred gears and air-tight bearings to the ergometer.
