Hi,As far as I understand from reading in the forum a workout can cause an insulin spike. I would like to learn a bit more about how this works and the science behind it but so far I haven't found much useful information. Could anyone recommend where I can find more information about this?
Not sure where you can find a good source. But from what I understand during exercise insulin production is decreased.
In one of the podcasts kiefer talked about crossfit raising blood glucose levels I believe. That's all I can remember though.

+1I remember this also. Â
Excess cortisol release liver glycogen in type 1 diabetics.Again, insulin doesn't increase during training unless intra-WO nutrition is used.
I see, so if insulin does not rise during training, does it rise after? Or is it just the PWO shake that causes a spike?

This happens in unhealthy people who don't have normal insulin production. Short of it is, if you aren't a diabetic, don't worry about it.

I'm not diabetic or worried, just curious how it works.

They have to take insulin to get the blood glucose to go down.In normal healthy people blood glucose wouldn't sky rocket during training in that way because the glucose would like get shuttled for use in training.

Yes, the PWO is what would cause the insulin spike post-workout; without nutrient ingestion during post-workout, insulin would remain low. Just as a summary: during training insulin drops, and while many other hormones spike, 2 that are of note in terms of metabolism are glucagon and epinephrine. Glucagon and epinephrine mobilize liver glcycogen stores and fat stores from adipose tissue during training to help increase blood glucose and FFA levels to support the increased energy demands of muscle during exercise. This explains why some will suggest that blood glucose levels actually increase during exercise (release of glucose from the liver exceeds the rate of uptake by muscle). Finally, glucose uptake is possible by muscle during exercise in the absence of insulin because of Ca+ signalling. During muscle contraction, Ca+ levels in the muscle increase and this provides a mechanism for glucose uptake in the absence of insulin.
