Abstract
[EN] Introduction: The Elevation Training Mask (ETM) is a respiratory muscle loading device that works by reducing airflow through a valvular system. The ETM was originally intended to simulate altitude by allowing the application of hypoxia during exercise and has been growing in popularity among athletes. Objective: To systematically review studies evaluating the effect of ETM associated with exercise on biomarkers, respiratory parameters, and sports performance indicators in physically active subjects. Material and method: A structured search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed in the Medline database (PubMed) until October 2021. Results: Six studies are included reporting that the use of ETM in comparison with the control group, presented a greater tendency to increase in forced inspiratory vital capacity, forced vital capacity, without significant changes in pulmonary function; it did not affect the total load volume of strength training but attenuated the speed of execution; it significantly increased cerebral oxygenation and decreased oxygen saturation; heart rate was higher while inter-beat interval and sympatho-vagal balance were lower; there were no changes in hematological variables although there was a tendency to decrease muscle damage and attenuate the direct catabolic effect derived from exercise; no improvements in sports performance were observed. Conclusion: The use of ETM as an altitude simulation device induces, if at all, a mild hypoxic stimulus that is clearly insufficient to trigger adaptive physiological responses on target organ systems. However, it could have some utility as a respiratory training system without combined exercise load by adequately adjusting the working resistances on the respiratory muscles
