Hypoxic training for Masters?

This article speaks to hypoxic training for swimming. It specifically mentions Counsilman's view on it. It also acknowledges later that there is no proof it improves the muscles ability to handle oxygen. ..... "Some coaches have suggested that hypoxic training can increase the buffering capacities of muscles and blood vessels because of the acidosis that occurs when oxygen supply is reduced. Hypoxic training is unlikely to be any more effective than free swimming for this purpose. In fact, it may be less effective for the reasons cited earlier, namely, that athletes can swim faster and thus with more racelike stroke rates and stroke lengths when they breathe regularly." Thanks for the link; although disputing the adaptations we've mentioned, the article did not at all seem "anti-hypoxic" in nature. The whole "athletes can swim faster with more oxygen" of course ignores underwater SDK, which is faster than most surface swimming and is my own reason for any hypoxic training I do. In fact, I was pleased to see that Austin Staab seems to approach his underwater training similarly to me with his whole "at least 7 kicks off every wall" to build underwater endurance. His interview is here. Pretty incredible that he could do the last 25 of his 100 fly without a breath.
