Fatigue and efficiency of high-intensity cycling
Summary
We are interested in exploring how fatigue relates to the energy cost of cycling exercise. Minimizing the energy cost of cycling may be a key determinant of cycling performance, and we want to explore how and why this energy cost may change with fatigue. Participants will be required to report to the laboratory for up to 13 total visits, each lasting approximately 60-120 minutes. Participants will first perform an incremental test to determine their maximal oxygen uptake, and then a series of three tests to determine their critical power (this should be an intensity that can be sustained for about one hour). Following these tests, participants will perform several constant load trials at varying work rates while monitoring ventilation, oxygen uptake and any changes in fatigue. Some of these trials will be to the limit of endurance.
