Elevation training masks claim to provide benefits to athletes which are similar to training at altitude or high elevations, but the true effects fail to stack up against these claims.

Training at altitude confers benefits to the athlete due to the lower concentrations of oxygen in any given unit of air, and this low concentration of oxygen is the reason the body responds by changing red blood cell counts and the makeup of hemoglobin and hematocrit.

In contrast, elevation training masks simply restrict the flow of air, but do not change the actual concentration of oxygen being inhaled. Because of this, elevation training masks will train the respiratory muscles, but not lead to hematological changes such as red blood cell count and hematocrit makeup.
