High intensity exercise raises blood sugar
As a Jazzercise instructor, we're required to work out very intensely, or we could fail our evaluations, and ultimately be terminated. I've been a Jazzercise instructor for 5 years, and just got the T2 diagnosis a few weeks ago. After teaching a class (usually late afternoon-evening), my blood sugar rises 50+ points. It does drops to a more normal level after dinner. I did talk to a nurse and she said the release of glycogen and adrenaline are the cause of the blood sugar increase ("fight or flight" response).
When I teach, I work out at about 98% of my maximum heart rate. My doctor is all for my continuing to teach, but I haven't discussed the huge increase in blood sugar with him. I feel totally fine both during and after class. I don't want to give it up because Jazzercise is the only exercise I've been able to stick with for over a decade, and I love being an instructor.
When I do low intensity exercise, like walking, that lowers my blood sugar, so if my after meal level is a bit high, I take a 20 min. walk and that brings it right down.
Has anyone else experience the huge increase in blood sugar after an intense workout, and is there any need for concern?
