Spain20 participantsStarted 2022-01-06

Plain-language summary

Introduction: The Elevation Training Mask (ETM) could restore respiratory or hematological organic damages from the acute or post-infection phase of severe acute respiratory syndrome coronavirus 2 (SARSCoV2) because it would allow the application of hypoxia and respiratory muscle training during exercise. The aim of this study was to comparatively evaluate the respiratory and hematological parameters and performance of athletes who resume CrossFit® training using the ETM with respect to a control group (CG). Material and methods: A single-blind randomized clinical trial, following the CONSORT ("Consolidated Standards of Reporting Trials") recommendations, 20 trained male athletes were randomly assigned to an experimental group (EG) using the ETM and to a CG using the simulated ETM, they completed 12 weeks of CrossFit® training after 1 month of the cessation of SARS-CoV-2 symptoms. Pre- and post-training tests included spirometric, hematological, and sports performance assessment.
