Raise your performance to the next level! This high-quality, altitude simulation mask works to enhance endurance in athletes who wish to elevate their overall physical fitness. This groundbreaking Altitude Fitness Sport Mask is a great tool to provide resistance and simulate the effects of high altitude to benefit non-pro and pro athletes alike.
Function: Gym Oxygen Control Fitness Training Mask has a 6-setting Toggle Switch to simulates different altitudes from 500 Meters to 6000 Meters. Specific settings are 500M, 1000M, 2000M, 3000M, 5000M, and 6000M. Mask is equipped with Carbon filter and is dustproof, windproof, anti-virus, and anti-smog. Applies to Cycling, Running, Hiking, and endurance sports.
The Science: During Fitness training at high-altitudes, the blood's erythropoetin (EPO) increases to a maximum level within one or two days of achieving high-altitude. High levels of EPO stimulates red blood cell production and increases blood hemoglobin levels to make more oxygen available to the athlete's body. The outcome is a NOTICEABLE BOOST in the individual's overall athletic performance and endurance by ~ 1-3%. This could be the difference between winning or not.
