About this study

Official title: Effects of Different Masks on Metabolic Parameters, Inspiratory Muscle Strength and Perceived Effort During Low Intensity Aerobic Exercise

The purpose of this study will be to assess the effects of the use of masks on inspiratory muscle strength, metabolic parameters, heart rate, subjective perception of effort and the sensation of dyspnea before, during and after an aerobic test of 30 minutes long and a fixed load at lactate threshold. A randomized study of repeated measures will be carried out. A total sample of 35 active participants will be recruited. All participants will carried out a lactate threshold test and then 3 visits to the laboratory (separated at least 48 hours from each other) in order to perform 3 test of 30 minutes long without mask, with a surgical mask or with a FFP2 respirator (in a randomized order) at an intensity around lactate threshold intensity. Maximal inspiratory pressure, oxygen saturation, heart rate, blood lactate concentration, subjective perception of effort and dyspnea will be assessed before, during and after the 3 fixed intensity tests.

What is being measured

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

  1. Inspiratory muscle strength

    Inspiratory muscle strength will be measured in mmHg with a Power-breathe device

    Measured: change from baseline inspiratory muscle strength after the 30 minutes test

Secondary outcomes (5)
  1. lactate concentrations

    lactate concentration will be measured in mmol/L with a Lactate Pro 2 device

    Measured: change from baseline after 10 minutes, 20 minutes and 30 minutes during the test

  2. oxygen saturation

    oxygen saturation will be measured in %

    Measured: change from baseline after 10 minutes, 20 minutes and 30 minutes during the test

  3. heart rate

    heart rate will be measured in beats per minute with a polar H10 device

    Measured: change from baseline after 10 minutes, 20 minutes and 30 minutes during the test

  4. rate of perceived effort

    rate of perceived effort will be obtained through the Borg´ scale

    Measured: change from baseline after 10 minutes, 20 minutes and 30 minutes during the test

  5. sensation of dyspnea

    sensation of dyspnea will be obtained through a visual analog scale from 0 to 10 points

    Measured: change from baseline after 10 minutes, 20 minutes and 30 minutes during the test

Questions about this trial

What is this clinical trial studying?

A study testing steady intensity aerobic test of 30 minutes long in people with Masks, run by Universidad Francisco de Vitoria 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 1 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 13 May 2021. 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. Some participants in this study may receive a placebo. 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?

Inspiratory muscle strength (time frame: change from baseline inspiratory muscle strength after the 30 minutes test). 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 13 May 2021.
