News — Oxygen (O2)

For decades scientists have known that athletes who train at high-altitude, and then compete at sea-level, have a competitive advantage over those who train at sea-level only. Prolonged exposure to hypoxia, or lowered oxygen levels like those found at high altitudes, results in higher red blood cell count, hemoglobin levels, and enhanced oxygen carrying capacity by the blood. To take advantage of the hypoxia effect, some elite athletes spend weeks training at high elevations before an event, especially if the event is to be held at high altitude. Today, companies have designed sealed portable tents and even entire workout rooms...
