solange du nur deinen postworkoutshake verzehrst mit ~60g maltodextrin oder ähnlichen, ist dieses doch recht schnell wieder aus dem blut verschwunden.
ist ja der sinn dieser recht kurze KH , dass sie schnell ins blut gehen.der insulin peak ist ziemlich anabol, und die glucagon ausschüttung, die ja wiederum positiv auf GH wirkt folgt dann auch bald wieder.
von daher "verlierst" du nur wenig GH tortz PWS.
war mir nicht ganz sicher (physiologie ist doch schon bischen her) und habs sicherheutshalber nochmal gegoogelt
"Insulin growth hormone relationship"
Dear Dr. Sears, On page 62 of your book you state "insulin retards the secretion of growth hormone from the pituitary gland". Several other sources state the exact opposite. For example, Tortora G and Grabowski S, Principles of Anatomy and Physiology 7th ed., page 529. They state that insulin is a stimuli that promotes secretion of HGH. If you are correct, then why do athletes use Insulin with HGH? Why has insulin been shown to promote muscle growth? For me the key issue is what to eat post workout. I thought that replacing my glycogen stores quickly was important. Items which are higher on the G.I. would accomplish this task more quickly. However, I do not want to decrease or inhibit HGH release. Lastly, the workout itself has already stimulated an increase in hGH secretion. Will food items which are high on the G.I. really suppress hGh secretion to such an extent as to 'undo' the increase in hGH? Please advise me on the best course of action. If you could include one or two scientific research papers that i could refer to it would greatly appreciated. Thanks, Steve Hooper in Perth Australia.
Dear Steve: Insulin is a storage hormone that drives nutrients (including amino acids) in the cells. It is true that insulin promotes the release of growth hormone. However, the insulin-induced release of growth hormone is mediated by induction of hypoglycemia with a corresponding release of the hormone glucagon that increases cyclic AMP levels. The release of growth hormone is mediated by the second messenger cyclic AMP which is inhibited by insulin but increased by glucagon. The intensity of your workout determines the extent of the release of growth hormone, and this occurs about 15-30 after the workout ceases. This is why I advise a small Zone snack immediately after a workout. It will raise both insulin and glucagon levels simultaneously so that nutrients are driven into the muscle cells, and there is corresponding release of growth hormone. This should be followed by a Zone meal within 2 hours after your workout to maximize glycogen re-synthesis. Ivy and co-workers have showed that combinations of protein and carbohydrate are superior to either macronutrient alone in stimulating glycogen synthesis after a workout.
