- Registration Number
- NCT06308432
- Lead Sponsor
- Universidad Católica San Antonio de Murcia
- Brief Summary
Controlled, double-blind, crossover clinical trial with six parallel arms depending on the combination of temperature and humidity (22º and 40% humidity, 35º 40% humidity and 35º and 65% humidity), with two differents intensity, to investigate and validate the physiological use of a sensor in recreational road cyclists.
- 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.
