Key result
Higher pedaling frequency drives a cubic power increase and linear oxygen consumption decrease during fixed-power loads.
Why the study?
To substantiate the biophysical reasons for the increase in the power of the anaerobic metabolism threshold during bicycle ergometer functional diagnostics as pedaling frequency increases.
Comparison
Pedaling frequency range from 40 to 140 rpm (0.73-2.56 m/s) on a bicycle ergometer

May warrant cadence standardization in ergometer testing; leaves open validation for clinical prognostic use.
This biophysical analysis demonstrates that during bicycle ergometry, higher pedaling frequencies increase power cubically while linearly decreasing oxygen consumption for a fixed-power load.
Yura et al. (2023) studied this question. Pedaling frequency on a bicycle ergometer was evaluated on Power and rate of oxygen consumption. Increasing pedaling frequency on a bicycle ergometer resulted in a cubic increase in power and a linear decrease in oxygen consumption rate during a fixed-power load.
