NCT04832893

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Inspiratory muscle strength

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

    change from baseline inspiratory muscle strength after the 30 minutes test

Secondary Outcomes (5)

  • lactate concentrations

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

  • oxygen saturation

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

  • heart rate

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

  • rate of perceived effort

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

  • sensation of dyspnea

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