Two questions:
A.) Has anyone made a study of physiologic changes that come when swimming? Since breathing is more intermittent than jogging/running, is anaerobic threshold different when, say, you're swimming continuous freestyle? Is it just reached earlier. Has anybody studied blood-gasses while a person is swimming?
B.) Speaking of Anaerobic Threshold --- what is felt when that point is reached? Is it just continuing to swim when your lungs are burning from oxygen debt?
Thanks much.

Yes this data exists, and it's been out there since 1980.
I learned most of what I now know about anaerobic threshold studying works of professor Ernest W. Maglischo.
His latest edition dates as of 2003. Exercise physiology takes even more space in this edition compared to his first.
His bible is called Swimming Fastest.
To answer another of your questions, nothing special is felt when reaching ***speeds*** corresponding to one's anaerobic threshold. It's normal after all, since anaerobic threshold involves performing at this ***speed*** long enough so that it ends up putting you in the red zone.
Currently, there are some studies being done (by one of my friends among other) which try to correlate AT with VT2. Ventillatory threshold 2 is the point where breathing becomes heavier. But I think that AT ***speed*** is reach well before VT2 even kicks in.
There's no burning sensations associated with swimming at AT. You either have the muscles resources (enough working muscle fibers and enough glygogen) or you don't. If you don't, it is unlikely that you can maintain speed associated with AT for a significant duration. Your lungs won't burn at all, you just won't have enough muscle power to maintain this speed.
