Details and patient eligibility

About

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.

Full 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.

Enrollment: 12 patients

Sex: Male

Ages: 18 to 45 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Male cyclists with more than two years of cycling experience.
• Perform tests without fatigue.
• Road bike training at least twice a week.

Exclusion criteria

• Participants with chronic illness.
• Have a long-term injury that prevents you from training in the previous month.
• Inability to understand informed consent.
• Use of diuretics in the month prior to or during the measurement period.
