The administration of oxygen as an ergogenic aid. Extra oxygen enhances performance only slightly if taken no more than a few seconds before a short-duration activity, but it can improve performance significantly if taken during an endurance activity. However, this is of little practical use because administration of the gas is too cumbersome. Despite its almost routine use after a burst of activity in some sports, oxygen supplementation does not seem to accelerate the recovery process.
