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?

My experience is quite the opposite, but I do a high intensity interval workout that consists of 8 repetitions of a 30 sec "sprint" at max heart rate on an elliptical trainer followed by a 90 sec jog. Repeat 8 times after a 3 min warmup at a jog pace, and in 17 mins I'm done. It always lowers my BS, and the most dramatic incident was a 70 pt drop. After 30 mins, tt bounced back 20 pts and held.
