[QUOTE="Bebo321, post: 947227, member: 68730"] Hi there, Sorry to confuse you. Insulin resistance is basically an inability for your body to utilise the insulin that your pancreas produces as effectively as it should. When we become nervous/excited or exercise to the point where our heart rate is elevated significantly, all of us (with or without diabetes) have an automatic stress response which triggers the liver to release glucose into the bloodstream. Think of it as your body's way of giving you the energy to outrun a dangerous situation (which is probably how it evolved). So, if you consider that during a race where you are trying to push your pace a bit, it is likely that your liver will kick out glucose to fuel your energy demands. If you have some insulin resistance, this can mean that if at any point your blood glucose levels begin to rise then the insulin that your pancreas releases won't work quite as effectively as it should. This is unlikely to be an issue when you're running, as your muscles will be gobbling up the excess glucose to fuel their work. When you finish running however you may notice a blood glucose rise. This is because once you finish an activity your liver doesn't automatically 'switch off' and there can be a bit of a time lag: [B] Liver releasing glucose into bloodstream + Low demand for energy by muscles = Blood glucose rise.[/B] This should certainly not put you off exercise however. It gets a little complicated but here's why: Everyone has little energy transporting cells in their muscles (they're called GLUT4 receptors) These little babies allow your muscles to suck up glucose out of the bloodstream, without any need for insulin. The more exercise you do, the more of these 'transporters' or 'receptors' you have, which means that your insulin no longer has to 'work as hard', because your muscles have an alternative route to take glucose out of your bloodstream. (So you effectively become less insulin resistant and your average blood glucose levels will improve). Regarding your run, from how you describe it I don't think blood glucose levels had anything to do with your performance, though it would be well worth investing in a test meter. Test before, during and after your run on two or three occasions to get an average 'pattern'. That way you will feel far more confident in the knowledge that everything is as it should be. Just as another point, as well as exercise, do make sure you watch how much carbohydrate you are eating (check out the low carb discussions on the forum). Unfortunately you won't be able to out-exercise a carb loaded diet. (Again, use the test meter to assess what sort of blood glucose rise you are getting after your meals) Keep it up, and best of luck in your next run!
