Study Overview
Status
Conditions
Detailed Description
Subjects who meet the inclusion criteria will be recruited to participate in the clinical trial and perform the exercise sessions.
The cyclists in the study will have to make 7 visits to the laboratory. At the first visit, their aerobic performance will be evaluated by an incremental test to exhaustion with gas analysis. And in the next 6 visits they will have to perform a sustained intensity exercise with different environmental conditions according to the combination of temperature, humidity and intensity.
