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?
- Literature research
- Develop test profiles
- Data acquisition
- Evaluate the influence of cadence
For extension towards a thesis:
- Find a model for the relationship between cadence and oxygen uptake for given power.
- Improve existing models for oxygen uptake for given power outputs.
- Knowledge of MATLAB or similar numerical software packages is of advantage.
