ClinConnect Summary

This clinical trial is studying how caffeine affects exercise and helps determine training zones for cyclists. Specifically, researchers want to understand how low and moderate doses of caffeine influence physical performance and whether these effects differ between men and women. Participants will be trained cyclists aged 18 to 45 who can complete a 20 km cycling time trial at a specific speed. Women must have regular menstrual cycles and not be using birth control pills.

During the trial, participants will complete four cycling tests. In the first test, they will find out their power outputs for moderate exercise. In the next three tests, they will take either a low dose of caffeine, a moderate dose, or a placebo (a harmless substance with no caffeine) before cycling. Throughout these tests, researchers will measure heart rate, oxygen use, blood lactate (a marker of exercise intensity), and how hard the participants feel they are working. This study aims to provide valuable insights into how caffeine can impact athletic training and performance.
