These masks, which cover your mouth and nose, cut down on the amount of oxygen you take in while exercising. Using the mask when training forces your heart and lungs to work harder. When you remove the mask for a race or game, your body uses oxygen more efficiently. Fans of altitude masks claim that using them can improve speed, endurance, and strength.\nThis concept is based on the fact that some athletes, especially distance runners, train at higher altitudes. Altitude training is believed to increase your body\u2019s red blood cell count, allegedly giving you a temporary performance boost when you return to sea level.\nWhat the Science Says About Elevation Training Masks\nDo training masks really work, though? And are there any real benefits to using elevation training masks? So far, research results are mixed.\nA study published in the Journal of Sports Science Medicine looked at the effects of altitude training masks on 24 athletes. Researchers found that these 12 athletes experienced improvements in respiration (breathing) compared to those who didn\u2019t use training masks.\nOther studies, however, haven\u2019t found any benefits from wearing training masks. In a study published in the Journal of Strength and Conditioning Research showed that wearing an elevation training mask while lifting weights was associated with decreased alertness and a lower ability to focus on the task.\nAt best, training masks might help you breathe more efficiently, but it\u2019s still unclear if or how that might improve athletic performance.\nKeep in mind that wearing an altitude mask might cause you to hyperventilate or even faint, due to its restrictive breathing. People who have high blood pressure or other cardiovascular problems should avoid using training masks.\nConsult your doctor before taking up a new training regimen or using new equipment.
