[QUOTE="Bebo321, post: 1596906, member: 68730"] Hi [USER=437905]@Sawds[/USER], As has already been stated, having high BGs after intensive exercise is not unusual. An adrenaline/cortisol surge triggers your liver to release glucose into your bloodstream in order to fuel your activity. There are a few factors you might want to consider when you are trying to manage your bloods though: 1. If you are very low carb (in effect Ketogenic) your body will be adapted to burning fats. As you increase the intensity of your exercise however, the body switches over to burning more glucose. (Think of fat as burning coal - slow and steady, vs glucose as lighter fluid - rapid high energy output). Once you've finished your activity and continue with low-carb eating, you have to understand that your body will have to work pretty hard to convert fats/protein to replace the lost glycogen. Therefore, after a decent bout high intensity exercise you might want to at least take on board some carb. 2. The highs after finishing - this is simply down to your liver continuing to release glucose into the bloodstream, but with a reduced rate of uptake from your muscles. You can manage this in a couple of ways; a) Have a 'cool down' period of exercise after your game - jog slowly/walk for a further 20mins or so. It's a case of lowering your heart rate, but continuing to keep mopping up the excess glucose. b) Have a snack. Whenever you eat, you get a corresponding insulin response. Insulin should counter the other hormones that lead to your hyperglycaemia. 3. Hypoglycaemia. This is the odd one. Are you taking metformin? Remember if you are ketogenic then blood glucose levels can actually fall lower than what would normally be classified as 'hypo', without you feeling any of the symptoms. Hypothetically, I suppose it could be possible that your adrenaline surge is overriding the action of metformin within the liver (metformin suppresses glucagon action - a trigger for glucose release). Once your heart rate becomes normalised however, you have insulin already circulating along with heightened sensitivity and glucose absorption potential within your muscles. At that point, metformin in it's role of moderating glucose release might actually be doing more harm than good - in that it is preventing your liver from keeping up with your body's demand for fuel. High demand, but suppressed supply = hypoglycaemia. What are your thoughts? [/QUOTE]
