Exercise and high BG

The release of ‘fight or flight’ hormones such as adrenaline make us insulin resistant.
So strenuous exercise can have a marked effect on BG post exercise.

Yes, same puzzle for me too. Normally exercising e.g. running, cycling will lower my blood glucose quite predictably. But when I play 90 minutes of football, same distance of running as a jog BTW, my blood glucose goes in the opposite direction and I end up at 15 or 16! Only solution I've found is to to eat and take QA insulin approx 2 hours before football, leaving just some of the insulin left over for during football. I'd be scared to take QA straight before a game. I think high intensity exercise, stop start etc, raises blood sugar, whereas long steady exercise like jogging lowers it. Anyone else find this?

I know why you get this, it is because when exercising the body releases carbs etc to help feed the muscle you are using during the exercise but it will I ly work if if you have insulin in your blood as the insulin acts as a key in this process. So lie no man bag says take some maybe an hour or two beforehand so that the carb released during exercise is allowed to do its job and feed the muscle, once you master this you will notice a huge improvement in your performance! This was one of the main reasons I did the Dafne course. I am a mixed martial artist and would go home after every training session with high blood sugar then during the night it would almost always crash towards a hypo( due to me taking insulin cause I though that was the right thing to do) . In all honesty Dafne did not cover the long period sof high impact exercise I participate in but trial and error with the knowledge I got from the diatitian etc. hope this helps, oh and even if it's background insulin you take a couple of hours before as long as there's some insulin that's maybe only be injected an hour or two before hand to unlock the the body's system , with out the insulin the the muscles do not get what's needed and you end up having high blood sugar peace!

Oh and do not correct it as your body is likely to go into a hypo ! Circuit training is similar to the kind of trainIng I do , depending on what ever time you exercise at there's ways around it

When lifting weights and doing activity that requires large amounts of energy and quickly the muscles will actually use their own stores of energy, and then suck it back in from the blood stream afterwards........so the body doesn't release carbs as such but glucose from the muscle stores and obviously the liver.....

Yeah they are called glycogen but I merely simplified it a bit for any who might not know what glycogen is or the whole ATP process, but your about right there ; )

Thanks so much for these posts! I'd forgotten all about that as I did the DAFNE course about 5 years ago and haven't really exercised much since. I hadn't noticed anything out of the ordinary happening after a bit of a run and sone gym work, but this evening I did a high intensity workout, combining weights, cardio and abs work, and my BG levels shot up. I was worried about it but I feel reassured after reading those posts!
