Self-Abuse Mask High Altitude Oxygen Blocking Training Mask Plateau Simulated Low Oxygen Mask Product Features Using this mask can simulate the state of high-altitude training in plain areas. In high-altitude environments, the air is thin and oxygen levels are low, preventing blood from absorbing oxygen normally, which causes the heart to beat faster.Training under this condition can strengthen lung capacity, diaphragm, cardiac load intensity, and anaerobic threshold.So when you return to low altitude environments, your athletic performance or training will improve, which is why many people go to high altitude for training.
