It's your metabolism telling your liver to make glucose to fuel your exercise. The problem for us is, we have insulin resistance, and the sugar doesn't get burned off as easily. The good news is, the more you exercise, the less you resistance have. So in the long run, you're better off. Spikes that used to last 2 to 3 days, now only last 90 minutes for me.
Intense exercise releases hormones - cortisol and epinephrine - which have the effect of temporarily raising blood glucose levels. What qualifies as 'intense' exercise varies from person to person - fitness levels and so on.
Moderate exercise (eg walking) will typically lower blood glucose levels if high when exercise begins, such as after meals containing carbs. A long walk can blunt the spike after a meal with a significant amount of carbs.
Exercise of any kind lowers insulin resistance in muscle tissue and has a lasting effect for 24 to 48 hours, so all exercise is good exercise even if it causes a temporary rise.
Vigorous cardio (full court basketball) yup. Still trying to figure out how to manage it. Moderate cardio, weight training, etc no issues. Would appreciate any tips!
I dip during the workout and then bounce back higher than I was before it falls back down to baseline. But I always exercise after eating which I’m sure is part of it.
I definitely go higher after the dip and rebound than I would if I hadn’t but it doesn’t last long and then I fall back down to my lower baseline. My normal is 95ish. I’ll drop to 65 during a workout and then when I stop I’ll hit 125 for a bit and then it’ll drop back down to 95 and then lower to around 80-85 once I go to bed.

Temporarily, it’s very short lived.
