Will hypoxic sets improve my ability to swim without air?

From what I understand, breath control training largely provides little (if any?) physiological training effect other than from the work itself (which is hindered anyway, making it a waste of time for training any of the energy systems). I assume there is room to mentally adapt and learn how to manage hypoxic suffering. But other than developing a strong aerobic base and increasing level of conditioning, can one actually have room to improve their hypoxic capacity specifically through hypoxic training? Thank you!

  • oh and we did this one test that really really hated....lactic acid. where you get your finger pricked every length. after a few days of that you are left with 1 finger that is not bruised and no way to pick anything up. We did lactic acid testing in college. Our test was always done in just a single day, but I still remember the finger bruising. I forget the exact protocol, but I remember doing a long swim at around threshold pace, then doing a 200 at maybe 90% effort, another long swim, then an all out 200 free. Our blood was drawn before and after the timed swims, I think.
