About this study

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Low intensityOther

    The subject will perform the 30-minute test at an intensity of 50% of the power at which he/she has reached his/her VO2max.

  • Low temperatureOther

    The performance test will be carried out in a room conditioned to a temperature of 22º.

  • Low HumidityOther

    The performance test will be carried out in a room conditioned to 40% humidity.

  • High intensityOther

    The subject will perform the 30-minute test at an intensity of 60% of the power at which he/she has reached his/her VO2max.

  • High temperatureOther

    The performance test will be carried out in a room conditioned to a temperature of 35º.

  • High humidityOther

    The performance test will be carried out in a room conditioned to 65% humidity.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sweat

    The amount of sweat will be measured by a sensor placed on the back.

    Measured: Change of baseline rate of sweet rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

Secondary outcomes (7)
  1. 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.

    Measured: Change of baseline rate of sweet rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  2. Heart Rate

    The heart rate will be evaluated by means of a heart rate strap.

    Measured: Changes of heart rate in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  3. Fatigue

    Rate of perceived exertion using Borg scale. En esta escala 0 representa nada fatigado y el 10 esfuerzo máximo.

    Measured: Change of fatigue in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  4. Temperature on the forehead

    The temperature will be measured by an infrared thermometer.

    Measured: Changes in Temperature on the forehead in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  5. Temperature in the ear

    The temperature will be measured by ear thermometer.

    Measured: Changes in Temperature in the ear in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  6. Sleep efficiency

    Measured by accelerometry, with Actigraph wGT3X-BT

    Measured: Changes in the sleep efficiency in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

  7. Karolinska drowsiness scale

    Measured by Karolinska test

    Measured: It will be measured the day after in six occasions (the first day, day 7, day, 14, day 21, day 28, day 35)

Questions about this trial

What is this clinical trial studying?

A study testing Low intensity, Low temperature and Low Humidity in people with Sweat, run by Universidad Católica San Antonio de Murcia at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sweat (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)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2024.
