[QUOTE="phoenix, post: 185124, member: 12578"] Glucose is moved into cells via glucose transporters. GLUT4 is the transporter which moves glucose into skeletal muscle cells. It is stimulated by insulin but also by muscle contraction It has two types of receptors and (it's thought) that there are sufficient that can be stimulated by muscle contraction to allow insulin into a cell for energy, some say this is true at all times, but certainly there are enough to get glucose into the cells during aerobic exercise. (competitive exercise and anaerobic exercise can be a bit different as they bring things like adrenaline into play) Insulin also acts to stop the liver releasing glucose.Quite frequently during exercise this is a problem with injected insulin, you need the extra fuel but a relatively high insulin level prevents the liver from releasing it. (hence hypo) I use hardly any insulin whilst exercising, nor for some hours afterwards. I have a pump and set it to 0.1units an hour for running.Today in fact I ran half of a 7 mile run without the pump attatched (for some reason it became really uncomfortable and itchy and I ended up taking the cannula out) . I can't say there was no insulin as there was probably some that hadn't yet been absorbed but there was very little, at the end of the run glucose level was 4.6mmol (and I had had some dextrose at the 2 mile point) When I run long runs (12 miles upwards) I eat carbs before and drink them during, all with no bolus insulin and very little basal.
