[QUOTE="borofergie, post: 268980, member: 33342"] For aerobic exercise (<85% ish of your max heart rate) your muscles are mostly burning fat (almost completely at low intensity, with an increasing amount of glycogen as the intensity increases). For anaerobic exercise (>85% ish of your max heart rate) your muscles only burn glycogen. Once your glycogen levels become depleted (by either type of exercise) you become exhausted and stop. Your muscle glycogen depletes very quickly during aerobic exercise, and most people cannot exercise at that intensity for more than about 20-30mins. The BG rise you are talking about is a result of your liver dumping glucose to refuel your muscle glycogen. Even on a ketogenic diet I get huge liver dumps if I exercise aerobically (5k races @93% max HR). I ran 7.5 miles last night aerobically and my BG went down. [/QUOTE]
