Efectos agudos y crónicos del uso de máscaras de entrenamiento en altura durante el ejercicio: revisión

The so-called Elevation Training Mask (ETM) is marketed for the purpose of emulating the hypoxic conditions that prevail at different altitude levels. The present work reviews the studies that analyze the acute and chronic effects of using ETM on variables associated with physical performance. Although there is some controversy, most studies report an acute hypoxic effect and improvements in cardiorespiratory parameters derived from using ETM, in addition to being, in general terms, well tolerated. For strength training, the use of ETM could be detrimental. More studies with different populations and studies with longer interventions are needed.
