An interventional study of Low intensity and Low temperature in Sweat, sponsored by Universidad Católica San Antonio de Murcia. Completed at 1 site in Spain. Open to male participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-06-24.
Sponsored by Universidad Católica San Antonio de Murcia · Not applicable, Interventional, and Other
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.
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.
Universidad Católica San Antonio de Murcia is the lead sponsor of 132 studies on the registry; 18 are open to participants now.
Counted across the registry records on this site, refreshed daily.

Sweat
The amount of sweat will be measured by a sensor placed on the back.
Time frame: Change of baseline rate of sweet rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Microcapillary Blood
By means of a lancet puncture in the thumb of the finger, 70 ml of capillary blood will be extracted.This test provides biochemical variables (ABL90FLEX) with 70 ml of capillary blood.
Time frame: Change of baseline rate of sweet rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Heart Rate
The heart rate will be evaluated by means of a heart rate strap.
Time frame: Changes of heart rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Fatigue
Rate of perceived exertion using Borg scale. En esta escala 0 representa nada fatigado y el 10 esfuerzo máximo.
Time frame: Change of fatigue in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Temperature on the forehead
The temperature will be measured by an infrared thermometer.
Time frame: Changes in Temperature on the forehead in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Temperature in the ear
The temperature will be measured by ear thermometer.
Time frame: Changes in Temperature in the ear in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Sleep efficiency
Measured by accelerometry, with Actigraph wGT3X-BT
Time frame: Changes in the sleep efficiency in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
Karolinska drowsiness scale
Measured by Karolinska test
Time frame: It will be measured the day after in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)
