Analysis of blood biomarkers and sports performance in crossfit athletes using the elevation training mask 2.0 post SARS-CoV-2 infection

This study aimed to comparatively evaluate the hematological profile and sports performance in CrossFit (R) practitioners training using Elevation Training Mask (ETM) 2.0 after recovering from COVID-19 (1 month with no symptoms). Twenty trained male athletes were assigned to an experimental group (E...

Sumario:This study aimed to comparatively evaluate the hematological profile and sports performance in CrossFit (R) practitioners training using Elevation Training Mask (ETM) 2.0 after recovering from COVID-19 (1 month with no symptoms). Twenty trained male athletes were assigned to an experimental group (EG) (n = 10) using configured ETM and a control group (CG) (n = 10) using sham ETM device. Both groups completed 12 weeks of CrossFit (R) training after 1 month of finishing SARS-CoV-2 symptoms. Pre- and post-training testing included assessment of hematological biomarkers, and sports performance parameters in a single-blind randomized clinical trial (ID NCT06806124) following the Consolidated Standards of Reporting Trials. No significant differences (p > 0.05) were observed comparing EG and CG in the hematological profile and sports performance parameters evaluated. Significant differences (p < 0.05), group by time interaction effect, were observed throughout the 36 training sessions for CrossFit (R) Total and Fran WOD. Our findings could indicate improvements in both groups, CG and EG, in performance tests, without reaching pre-SARS-CoV-2 infection levels. Furthermore, ETM does not appear to function as an altitude simulator under the experimental conditions developed in the present intervention.
