After a full day of skiing my blood sugar levels are very high. All other exercise lowers my blood sugar. Does anyone else suffer from this? I take minimal insulin based on food intake as I do with other sports, but leave my insulin pump turned on at 100%.

me too when I run marathons my level really rises but when i bike
for 3 to 4 hours i am in hypo. i ve contacted this group because i
am seriously considering a pump for the next marathon in september
and want to learn if a pump is a help for this


The same thing happens to me. After intense hockey training or a hockey match my blood sugars are always really high whereas after an intense tennis match or tennis training or even at the gym my bloods are either normal or low. I agree that adrenaline can have a factor so i just test my BS when possible during it though it is difficult to stop and test them in a match

I'm all over the road on this and still trying to figure it out. If I walk, run on a treadmill, ride my offroad motorcycle, or ride my sportbike on a track, I go low at various rates depending on the intensity. If I ride my mountainbike or do any type of resistance training like weights, lunges, pushups, I go high. I would love to have more insight into what is causing what.

I'm a T1 LADA on a low carb Bernstein diet and do MDI.

It's generally explained as a conversion of glycogen to glucose in the liver in response to adrenaline. This causes a post work-out BG spike. High intensity anaerobic activities in short bursts don't burn free glucose in the blood like extended aerobic activities do.

Just an anectdotal thing, but I've noticed low-carbers seem to have more of an issue with the post exercise highs. I don't low carb and most of my work-outs are high intensity type activities. I'll rarely spike over 120 after a work-out. I do crash big time though whne I do extended aerobic activities.
