[QUOTE="phoenix, post: 131052, member: 12578"] In people without diabetes insulin is 'turned down' during exercise 1) because the cells become much more insulin sensitive (ie less resistant) 2) During exercise other glucose transporters that don't need insulin are also utilised. One of these in particular may be switched on when glucose levels are low but the whole thing is very complex and scientists haven't yet fathomed out exactly what happens. However a small amount of circulating insulin is always needed. So the insulin you are producing is able to be used much more efficiently. I need very little insulin during exercise and because I wear a pump can turn my insulin down to a trickle during exercise. I did a three and a half hour hilly run/walk on Sunday with a basal rate of 0.2units an hour, I needed 3 glucose tablets and ended up with a bgl of 4.1mmol . Nevertheless I need that tiny trickle: the one time the cannula came out during a run I ended up with a bgl of 17mmol with ketones . [/QUOTE]
