Thomas Delauer answered a question that I have had for several years. When I began wearing a continuous glucose monitor, one of the first things that I noticed was that my glucose spiked during intense workouts (which are the majority of the CrossFit mainsite workouts). It would climb higher than with any food that I ate and then return to baseline within 30 minutes. My concern was whether that in turn caused my insulin to spike. I wondered about the feasibility of a continuous insulin monitor to help answer this.  Delauer has cleared up this mystery and the answer is no. The mechanism is exercise-stimulated glucose transport as opposed to insulin-stimulated glucose transport. As if that weren't enough, there is an increase in postexercise insulin sensitivity up to 48 h after exercise.                                                          https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4727532/
My next question is: Since exercise increases the glucose area under the curve, does it also affect hga1c?
