The Role of Cadence on Oxygen Uptake Kinetics in Cycling


Respiratory gas exchange measurements are a common method to assess physical fitness and endurance capabilities of athletes. We develop models for predicting oxygen uptake kinetics with respect to a persons power output on a cycle ergometer. These models have successfully been validated with ergometer cycling exercises at a constant cadence.

However cycling exercise in the field is not restricted to constant cadences. Therefore some open questions remain. For example:

  • Has a varying cadence an influence on the oxygen uptake and if so, to what extent?
  • Does the maximal oxygen uptake change for different cadences?
  • Finally, if there is an influence, how can we adjust our models appropriately?


  1. Literature research
  2. Develop test profiles
  3. Data acquisition
  4. Evaluate the influence of cadence

For extension towards a thesis:

  1. Find a model for the relationship between cadence and oxygen uptake for given power.
  2. Improve existing models for oxygen uptake for given power outputs.


  • Knowledge of MATLAB or similar numerical software packages is of advantage.
