Posting this again after receiving more questions from members..thanks for bringing up a great topic:


1) Hyperglycemia IMMEDIATELY after exercise is normal.
2) When we exercise a number of counterregulatory hormones are secreted (glucagon, epinephrine, norepinephrine, growth hormone, and cortisol.)
3)The body increases the amount of glucose available for active muscles and increases their glucose uptake.
4) THE FIRST EFFECT to kick in is increased blood glucose from the breakdown of muscle and liver glycogen so that the INITIAL response to exercise is a slight rise in blood glucose.
5) HOWEVER within a few minutes the muscles are more able to absorb glucose so the net result of exercise is typically decreased blood glucose.

Hope this helps
Dr O.
