[QUOTE="Brunneria, post: 1318455, member: 41816"] I find that my IR drops with exercise, but it has to be something that stretches me a little. The normal park trundle with the dogs doesn't really cut it. Whereas a good stride out with sustained muscle warmth will drop my IR nicely. A lot depends on fitness levels, so the exercise needed to have an effect is going to increase as fitness increases. Then I find that the reduced IR will persist for a while - but that depends on how long I exercised, how hard I exercised and how quickly I needed insulin afterwards. For instance. A half hour brisk walk might drop my IR nicely for a couple of hours, while a long 4 hour hike on a coast path or hills, might drop my IR for the rest of the day, maybe even overnight. BUT if I eat something carby, my body produces insulin to deal with it (I am type 2) and my IR returns more quickly than if I stayed low carb. Does that make sense? Of course, since you are T1 you are injecting insulin instead of having an over-helpful pancreas like I do, but I presume the principle remains the same - because it is insulin that causes IR (raised levels for extended periods), and that can come from a needle or the pancreas, the effect is going to be similar.
