The purpose of this study was to determine how effective the elevation training mask is at replicating the effects that altitude has on physiological responses. In this study, two physically active male track and field athletes were selected, one representing the control group and the other representing the experimental group, also known as the group wearing the elevation training mask for 8 hours a day. Each participant was subject to a series of test conducted before, during, and after the 6-week long study was complete. Resting heart rate, blood pressure, percent saturation, forced vital capacity(FVC), aerobic capacity, hemoglobin and hematocrit all being tested before and after the study. While resting heart rate, blood pressure, hemoglobin and hematocrit were tested biweekly during the duration of the study.
