Hard exercise with T2 and insulin

[martinsk8r]

Could anyone with experience give me some clues as to how to manage my blood glucose levels.

I'm 55 and exercising very hard as I have started Roller Derby. My question is, do I inject more or less before hard exercise?
Also, can I drink an electrolyte sports drink with carbs to try to reduce fatigue?

Has anyone found a way to keep exercising in a power sport?

I play ice hockey and find I have to inject less when playing/training. I get a slight rise in BS while playing but find it balances itself out later when it reduces. I wouldn't start exercising below 6, find I might get to 10 or 12 by the end of an hour but then be back down between 4 and 7 several hours later, possibly lower if I don't have a snack.

I have a low carb electrolyte drink which I have mainly because it tastes nicer than water, but I don't use the ones with carbs in, other than I keep some lucozade for hypos.

I find the isotonic carb drinks 4-6% carbs are useful on more endurance things like distance cycling than on high intensity anearobic stuff.

It will be experimenting a bit to start with testing your sugars a bit more often and seeing. Also I've always gone with being a bit high won't kill me for the odd afternoon when trying a new sport. Went snowboarding for the first time and started at 9 expecting a Bs drop, but actually didn't find learning as hard as people say and was still in the 10s an hour later, so corrected then. Means I know I can start out a little lower next time I go.

Thanks for the reply. It seems you are in a similar level of exercise sport. In desperation I contacted the diabetic unit at the local hospital and they advised exactly the same. 20% less insulin and maybe try 40% less next time. So... I tried this and ran the session at 7.4 to 8.5 and felt great during and after. Next day was competition and started at 9.0 but in second half it went over 16. I was hot, felt weak and had no mojo! I drank plenty of water. I had no insulin but probably too late anyway. I will get an low carb isotonic drink and take insulin to get session. I thought my tiredness was always low sugars so took carbs. What a mess. So as in your reply I will continue to test before during and after.
PS. I think the adrenalin played a large part. More research needed.
