[QUOTE="Member496333, post: 1957656"] My understanding is that when you exceed your aerobic threshold, you begin shifting more toward burning only glucose, and so the liver will begin secreting more of it. I believe that this “threshold” (which isn’t actually a ‘line in the sand’ at all) is generally somewhere around 180bpm (beats per minute) minus age. The closer to it, or the further you go above it, the more likely you are to experience a blood glucose spike. This topic is a practical example of why you’ll see many people refer to “moderate” exercise being ideal for diabetics - anything too much more for too long will raise your glucose level instead of lowering it. Brisk walking and mild resistance training = good. Olympic 400m hurdles = bad. I am however very sure that there’s far more to it than my simplistic explanation :) [/QUOTE]
