DO you guys think it is possible for insulin to benefit a diabetic in bb the way it would a non diabetic?
Sorry its taken so long to get back to this---as some of you know, one of my research interests is the management of diabetes in nondomestic species, with most of the principles of human diabetes being applied to the other animals. One thing that holds true with insulin in all mammalian species has essentially the same function. Herbivores, ruminants like cattle and hind gut fermenters like horses, have a slightly different effect because of the "continuous" secretion of energy (glucose) from the bacteria in their GI tract breaking down plant materials, but by and large the function is the same with strict herbivores as it is with omnivores.
I think there is a night and day difference between a diabetic and a non diabetic weight training athlete. Homeostasis is the key. Remember blood glucose is strictly managed in the body because glucose is the fuel for the brain. The body has a very good mechanism for lowering blood glucose if its too high (insulin) and raising it if its too low (release of stored glycogen, epinephrine, cortisol secretion), but the ultimate goal is to keep blood glucose within a set range at all times so the brain has the fuel it needs to work. If the brain works, then so does the rest of the body.
This is one of the reasons I've questioned (in some cases severely) the taking of insulin by nondiabetic bodybuilders. There is no denying the anabolic properties of insulin, but many people seem to forget it not only stimulates muscle growth by facilitating the uptake of glucose and amino acids, it also stimulates fat storage. Simply put, insulin will make you store body fat and it will severely inhibit bodyfat loss in the absence of an extreme diet. Not only that, but when a person takes exogenous insulin, their blood sugar will decrease from the insulin they are taking. The body will compensate immediately by release of epinephrine, cortisol, and stored glycogen. This is a major stress response. Not only that, but low blood sugar, left unchecked will result in loss of consciousness, seizures, and eventually death. Stimulation of these stress hormones are something you don't necessarily want, especially if you are doing it after strenuous exercise because it will inhibit recovery.
So how do the pro bodybuilders get by with taking insulin? I personally think that several of them may have undiagnosed insulin resistance due to HGH and excessive anabolic steroid administration. This insulin insensitivity means it will take more to have an effect, thus enabling them to inject the volumes of insulin that they do and "get by with it" without dying. I also think there is probably a whole lot more minor incidents that are simply unreported. Lets face it, high level bodybuilding is by and large a drug infused sport that because of the legal reprecussions of the drugs, many, many things are not talked about publically.
Its well documented that HGH administration results in decreased insulin sensitivity. Anabolic steroids are a bit more complex because androgens like testosterone will, at lower doses, actually sensitize the body to insulin---a prime example of this are the Type II diabetic males who are testosterone deficient who then go on HRT and miraculously have stabilized blood sugars. At much higher doses, anabolic steroids seem to have a desensitization effect for insulin, meaning that they can cause insulin resistance. Put those two together and you've got a recipe for Type II diabetes, which is also very well documented as largely being undiagnosed in many of the people who have the disease.
Now how does this apply to a diabetic? The problem with diabetics is that they are missing a major link in blood glucose homeostasis. I think the absolute goal of a diabetic should be to have normal blood glucose levels or as close to normal as physically possible. That person will then be in an optimal state for muscle growth and recovery. Will the insulin help . Will it make a diabetic 'grow bigger'? I didnt' think you can make that assessment because if a nondiabetic bodybuilder doesn't take insulin, they are a nondiabetic bodybuilder. If a diabetic bodybuilder doesn't take insulin, they are a ketoacidotic, dying bodybuilder. You cant run a control on the study because of the specificity of the disease and the simple fact that the body needs insulin for normal homeostasis.
What about the diabetic bodybuilder who juices? I think a Type I diabetic is an idiot to take HGH because of its effects on blood glucose. All you need is Type I diabetes with insulin resistance. Thats a recipe for elevated blood glucose levels and complications from diabetes, which will keep you from doing anything as a diabetic. As far as the anabolic steroids go, I'm still undecided on that one. Generalized testosterone deficiency--typically secondary, is not necessarily uncommon in long term Type I diabetics with good blood glucose control. No one knows why that occurs--its thought to be due to vascular damage within the pituitary gland and/or the testicle, but that hasn't been proven. These diabetics develop insulin resistance secondary to low Test levels. That insulin resistance will go away when they begin HRT doses of testosterone.
I hope that answered your question, if it didn't, let me know.
