oxygen levels in order to provide for aerobic life forms. As dissolved oxygen levels in water drop below 5.0 mg/l, aquatic life is put under stress. The lower the concentration, the greater the stress. Oxygen levels that remain below 1-2 mg/l for a few hours can result in large fish ...
When training at altitude, it is more difficult for us to extract a proper amount of oxygen from the air. Oxygen levels at sea level are typically around 21% but can drop to 15% at altitudes of over 3,000m. Training at altitude can force useful adaptations in an athlete, helping them...
