Zone 2 Training and Hypoglycemia

[bkh]

@Eric is our local expert on this. He has helped several folks. I’m thinking especially of the thread where he worked with Daisy Mae on how to maintain good BG while swimming. Daisy Mae's swimming BG thread A few of the basics I remember are (1) enter the exercise with a good BG (maybe like 120 or 140), not a hugely elevated BG like your 230, and (2) no IOB at the start of exercise, because the muscles have a different path to vacuum glucose out of the bloodstream and IOB will compound the BG drain, causing a low. And (3) after the exercise the glycogen has been used up, so the body will try hard to rebuild the glycogen stores by using up BG. Don’t try to fight this, work with it by taking lots of fast carbs and a modest amount of insulin. When the glycogen stores are reestablished the tendency to post-exercise lows will cease.
