Abstrakt: The oxygen uptake kinetics during constant-load exercise when sitting on a bicycle ergometer were determined in 7 untrained subjects by measuring breath-by-breath $$\dot V_{{\text{O}}_{\text{2}} } $$ during continuous exercise to volitional exhaustion (mean endurance time=1160±172 s) at a pedal frequency of 70 revolutions · min−1. The power output, averaging 189,5 W, was set at 82.5% of that eliciting the individual $$\dot V_{{\text{O}}_{{\text{2}} {\text{max}}} } $$ during a 5 min incremental exercise test. Throughout the exercise period, the $$\dot V_{{\text{O}}_{\text{2}} } $$ kinetics could be appropriately described by a two-component exponential equation of the form:
