Guest guest Posted February 12, 2008 Report Share Posted February 12, 2008 I believe that whist 'micro-managing' your hormones is far from practical, being aware of methods that could possibly elevate GH levels is vitally important for athletes of all levels, strength coaches, personal trainers etc... Being aware that muscle afferent feedback, blood lactate concentration, exercise intensity, multiple daily sessions and sleep can all possibly elevate GH will surely only lead to more informed programme structuring and better results without wasting your and/or your athletes time on trial and error? In addition, such information does not require much extrapolation to an every day training context. There is a lot of research out there that can help optimise training. I have read the Ratamass & Kraemer article mentioned in a previous post . This article and others like it have helped me no end in my own training and that of those who I train. This is a good thread I would be grateful for any more references regarding the subject Thanks, Chapman. Nottingham, England Re: Natural Ways to Elevate T and GH Yes, I know, but you are still missing the point. The point is that explicitly trying to micromanage your hormones seems to be an unnecessary middle-man. Much, much more is known, through basic trial-and-error about the correlation between diet and exercise behaviors and obvious results like fitness and strength than about how hormones fit into the middle of it. Getting preoccupied with the hormones is going to narrow you down to looking at a handful of highly specific scientific studies and doing a lot of speculation and extrapolation. I think this is a good topic for scientific study, but as an individual who is looking to train oneself or others, it seems like an unnecessary complication at best, something that could seriously lead you astray at worst. It brings to mind Nautilis machines or baroque double-split bodybuilding routines full of isolation exercises. These are training practices that seem to have resulted from convoluting anatomical and other types of analysis with much simpler questions about what kind of training works.

Guest guest Posted February 12, 2008 Report Share Posted February 12, 2008 Dr. Ralph, I am very interested in the subject matter. Do you mind emailing the 64 pages in a pdf format? Thanks for your time Huntsman Florida, USA ============================ Ralph Giarnella wrote: Natural ways to elevate H & T These discussions concerning hormones and attempts at manipulating them to our liking is always very frustrating for me. I find it frustrating because there are way too many posts trying give simple answers to a very complex topic. It is even more frustrating when someone writes a post and states just do this and you will raise your HGH or if you eat this your testosterone will go up or down etc. Often someone will cite an article in which 20 college students performed a certain task for a specified period of time and as a result their testosterone went up or down etc. They then postulate that anyone who does the same thing will have the same result irrespective of age, gender etc At times these discussions remind me of the story of the 4 blind men trying to describe what an elephant looks like based on the different parts of the body each of one the was feeling. I have to agree with when he states " The point is that explicitly trying to micromanage your hormones seems to be an unnecessary middle-man. " Hormones are very complex in thier actions and interactions with each other. There are age related changes as well as gender differences and time of day and month differences. A recent posting by showed that there are also seasonal changes. There are differences in hormones in various stages of growth and development even within the same individual. This same HGH behaves differently in men than it does in women. To illustrate the complexity of hormones I have taken the liberty of posting some excerpts from a well respected Textbook of Endocrinology. You can probably find a copy at the library of your local Hospital and check out the information for yourself. I can send a PDF copy of the chapter in question (64 pages) to anyone interested in studying this very complex subject. Ralph Giarnella MD Southington Ct USA ********************************************* Kronenberg: Textbook of Endocrinology, 11th ed. HYPOPHYSEOTROPIC HORMONES AND NEUROENDOCRINE AXES **************************** Human Growth Hormone Rhythms Endocrine Rhythms Virtually all functions of living animals (regardless of their position on the evolutionary scale) are subject to periodic or cyclic changes, many of which are influenced mainly by the nervous system (see Table 7-4 for definitions). [86] [87] [88] [89] Most periodic changes are free-running; that is, they are intrinsic to the organism, independent of the environment, and driven by a biologic “clock.” At least three distinct categories of GH rhythms, which differ markedly in their time scales, can be considered here. The daily GH secretion rate varies over two orders of magnitude from a maximum of nearly 2.0 mg/day in late puberty to a minimum of 20 µg/day in older or obese adults. The neonatal period is characterized by markedly amplified GH secretory bursts followed by a prepubertal decade of stable, moderate GH secretion of 200 to 600 µg/day. Puberty: There is a marked increase in daily GH secretion during puberty that is accompanied by a commensurate rise in plasma IGF-I to levels that constitute a state of physiologic hypersomatotropism. This pubertal increase in GH secretion is due to increased GH mass per secretory burst and not to increased pulse frequency. Although the changes are clearly related to the increases in gonadal steroid hormones and can be mimicked by administration of estrogen or testosterone to hypogonadal children, the underlying neuroendocrine mechanisms are not fully understood. One hypothesis is that decreased sensitivity of the hypothalamic-pituitary axis to negative feedback of GH and IGF-I leads to increased GHRH release and action. Young adults have a return of daily GH secretion to prepubertal levels despite continued gonadal steroid elevation. The so-called somatopause is defined by an exponential decline in GH secretory rate with a half-life of 7 years starting in the third decade of life. GH secretion in young adults exhibits a true circadian rhythm over a 24-hour period, characterized by a greater nocturnal secretory mass that is independent of sleep onset. [230] However, as discussed earlier, GH release is further facilitated when slow wave sleep coincides with the normal circadian peak. Under basal conditions, GH levels are low most of the time, with an ultradian rhythm of about 10 (men) or 20 (women) secretory pulses per 24 hours as calculated by deconvolution analysis. [231] Both sexes have an increased pulse frequency during the nighttime hours, but the fraction of total daily GH secretion associated with the nocturnal pulses is much greater in men. Overall, women have more continuous GH secretion and more frequent GH pulses that are of more uni-form size than men. [231] A complementary study using approximate entropy analysis concluded that the nonpulsatile regularity of GH secretion is also significantly different in men and women. [232] These sexually dimorphic patterns in the human are actually quite similar to those in the rat, although the sex differences are not as extreme in humans. [208] [232] The neuroendocrine basis for sex differences in the ultradian rhythm of GH secretion is not fully understood. Gonadal sex steroids play both an organizational role during development of the hypothalamus and an activational role in the adult, regulating expression of the genes for many of the peptides and receptors central to GH regulation. [203] [208] In the human, unlike the rat, the hypothalamic actions of testosterone appear to be predominantly due to its aromatization to 17 & #946;-estradiol and interaction with estrogen receptors. Hypothalamic somatostatin appears to play a more prominent role in men than in women in the regulation of pulsatile GH secretion, and this difference is postulated to be a key factor in producing the sexual dimorphism. [231] [233] [234] Important triggers of GH release include : the normal decrease in blood glucose level after intake of a carbohydrate-rich meal, absolute hypoglycemia, exercise, physical and emotional stress, and high intake of protein (mediated by amino acids). Some of the pathologic causes of elevated GH represent extremes of these physiologic signals and include protein-calorie starvation, anorexia nervosa, liver failure, and type 1 diabetes mellitus. A critical concept is that many of these GH triggers work through the same final common mechanism of somatostatin withdrawal and consequent disinhibition of GH secretion. Some factors that inhibit GH release postprandial hyperglycemia, glucose infusion, elevated plasma free fatty acids, type 2 diabetes mellitus (with obesity and insulin resistance), and obesity are all associated with inhibition of GH secretion. The role of leptin in mediating either increases or decreases in GH release is complicated by its multiple sites of action and coexistent secretory environment. Similarly, other members of the cytokine family including IL-1, IL-2, IL-6, and endotoxin have been inconsistently shown to stimulate GH in humans. The actions of steroid hormones on GH secretion are complex because of their multiple loci of action within the proximal hypothalamic-pituitary components in addition to secondary effects on other neural and endocrine systems. Glucocorticoids (Cortisol) in particular produce opposite responses that are dependent on the chronicity of administration. Moreover, glucocorticoid effects follow an inverted U-shaped dose-response curve. Both low and high glucocorticoid levels reduce GH secretion, the former because of decreased GH gene expression and somatotroph responsiveness to GHRH and the latter because of increased hypothalamic somatostatin tone and decreased GHRH. Similarly, physiologic levels of thyroid hormones are necessary to maintain GH secretion and promote GH gene expression. Excessive thyroid hormone is also inhibitory to the GH axis, and the mechanism is speculated to be a combination of increased hypothalamic somatostatin tone, GHRH deficiency, and suppressed pituitary GH production. Feedback Concepts in Neuroendocrinology In order to understand the regulation of each hypothalamic-pituitary-target organ axis, it is important to understand some basic concepts of homeostatic systems. A simplified account of feedback control in relation to neuroendocrine regulation is presented in this section. [83] [84] [85] Hormonal systems form part of a feedback loop in which the controlled variable (generally the blood hormone level or some biochemical surrogate of the hormone) determines the rate of secretion of the hormone. In negative feedback systems, the controlled variable inhibits hormone output, and in positive feedback control systems, the controlled variable increases hormone secretion. Both negative and positive endocrine feedback control systems can be part of a closed loop, in which regulation is entirely restricted to the interacting regulatory glands, or an open loop, in which the nervous system influences the feedback loop. All pituitary feedback systems have nervous system inputs that either alter the set-point of the feedback control system or introduce open-loop elements that can influence or override the closed-loop control elements. In engineering formulations of feedback, three controlled variables can be identified: a sensing element that detects the concentration of the controlled variable, a reference input that defines the proper control levels, and an error signal that determines the output of the system. The reference input is the set-point of the system. Hormonal feedback control systems resemble engineering systems in that the concentration of the hormone in the blood (or some function of the hormone) regulates the output of the controlling gland. Hormonal feedback differs from engineering systems in that the sensor element and the reference input element are not readily distinguishable. The set-point of the controlled variable is determined by a complex cascade beginning with the kinetics of binding to a receptor and the activities of successive intermediate messengers. Sophisticated models incorporating control elements, compartmental analysis, and hormone production and clearance rates exist for many systems. ********************* <<<Note: this is the point I was making concerning hormone supplementation- (Testosterone and HGH for example) when you supply hormones it exogenously it signals the body to stop making them-RG MD)>>>> ********************** Serotonin's effect on GH release in humans was difficult to decipher because of the large number of receptor subtypes. However, clinical studies with the receptor-selective agonist sumatriptan clearly implicated the 5-HT1D receptor subtype in the stimulation of basal GH levels. [225] The drug also potentiates the effect of a maximal dose of GHRH, suggesting the recurring theme of GH disinhibition by inhibition of hypothalamic somatostatin neurons in its mechanism of action. Histaminergic pathways acting through H1 receptors play only a minor, conditional stimulatory role in GH secretion in humans. Acetylcholine appears to be an important physiologic regulator of GH secretion.[226] Blockade of acetylcholinergic muscarinic receptors reduces or abolishes GH secretory responses to GHRH, glucagon and arginine, morphine, and exercise. In contrast, drugs that potentiate cholinergic transmission increase basal GH levels and enhance the GH response to GHRH in normal individuals or in subjects with obesity or Cushing's disease. In vitro acetylcholine inhibits somatostatin release from hypothalamic fragments, and acetylcholine can act directly on the pituitary to inhibit GH release. Many neuropeptides in addition to GHRH and somatostatin are involved in the modulation of GH secretion in humans (see Table 7-5 ). [203] [208] Among these, the evidence is most compelling for a stimulatory role of galanin acting in the human hypothalamus by a GHRH-dependent mechanism. A larger number of neuropeptides are known or suspected to inhibit GH secretion in humans, at least under certain circumstances.[208] The list includes NPY, CRH, calcitonin, oxytocin, neurotensin, VIP, and TRH. 203.

However, one would be naive not to be aware of the substantial industry in anabolic drugs -- mostly hormones or analogues -- in professional sport, many of which do provide a substantial advantage. American baseball is going through a very tough period of soul searching over the use of steroids and related compounds in the sport -- as I'm sure many Supertrainers are aware. Having said that, I do support " natural " athletes and I consider it important that any small advantage that can be got from training in a particular natural way should at least be noted for consideration, especially if a slight change in training modality has no great impact on training logistics. Regarding studies in the sports sciences: Like the nutritional sciences, and unlike many trials in medicine or pharmacology, the sports sciences suffer from small budgets and inadequate team resources. The large, randomised controlled trials that we have come to expect as the gold standard of evidence in the biomedical sciences are, generally, not possible in the sports sciences. We have to glean what we can from much smaller studies and make the best of it. It is true that we cannot attribute much evidence from many of these studies with just a few participants and few controls. Even so, they can contribute to meta analyses over time, and we may gain some understanding of the complex nature of sports physiology and biochemistry by being aware of consistency in findings over time.

The problem here is that when dealing with testosterone and HGH there are just too many variables to try and control all of them in order to attain ideal levels. When dealing with blood sugar you can have instant feed back with a simple blood test which costs just pennies to perform and can be done on a daily basis and within a timely fasion. With regards to lipid profile it is easy enough to see the results with blood tests. Lipids (except for triglycerides) do not change drastically from day to day so that you can follow a regimen for a month or two and see if you have made a change. When it comes to HGH an testosterone the target is elusive since there is a variability of these hormones from day to day and within the same day. Unless you are taking serial blood tests before and after your manipulations there is no way to know whether they had the desired effect. Even if you did a study on a group of individuals under controlled circumstances the results may not necessarily apply to others unless you follow the same controlled circumstances and were of a similar age and gender as the controls. For instance while cortisol is important for HGH too much cortisol and too little cortisol have a negative effect on HGH. Cortisol is highly variable with a circadian rhythm. It is at its lowest in very early morning and naturally continues to rise until the late afternoon after which it begins to decrease. However even this varies between individuals. For some it reaches its peak earlier in the day and for other it reaches its peak later in the day. In young adults it tends to peak late in the day (that is why they tend to stay up late and have trouble getting up in the am) and in older folks it tends to peak earlier. In studies on cortisol rhythms these two type of individuals are designated as larks and owls. Cortisol can also vary based on how much sleep you get or don't get, the state of stress in your life,(work, financial, emotional, exercise etc) the state of your nutrition. An intense workout is good for stimulation of these hormones but too intense can be detrimental since it may cause too much elevation of Cortisol. If the exercise is too intense as to cause a drop in glucose availability cortisol kicks along with glucagon to produce more glucose. High carbs are very good for HGH but if your postprandial blood sugar is too high it can be detrimental. This varies from person to person depending on their ability to produce enough insulin to control the rise in post prandial blood sugar. There are many individuals who are not diabetic but have an impaired glucose tolerance. Serotonin has an effect on HGH and this is in turn is affected by stress. Based on genetics some people produce more serotonin under stress (this is good for the individual) and some produce less serotonin under stressful situations (this is bad for the individual- often the cause of depression). You may be able to control some variables but there are too many variables that you are unable to control. Your best bet is to just find a good regimen that works good for you ( a good balanced diet, exercise, sleep, stress management et)c and choose your parents wisely. There is more to getting good results than just elevating T and GH. > Is it possible (or even likely) that a large portion > of the benefits that we attain from our workouts is > due to how our workouts manipulate T, GH (and maybe > insulin).

The technology is there to measure in the lab and on the mice and test subjects but it is not practical for the individual exerciser. What they discover in the mice and in the college students (most of these studies are done on students looking for extra money or credit) does not necessarily translate to the general public. We know from medicine that just because something works in the lab or in a small group of test subjects does not mean that it will work in the general population. That is why they have to do field studies often involving 10s of thousands of subjects over a long period of time. Sometimes what was originally thought to be safe or effective in a controlled environment turns out to be not as safe or not as effective. I find it very curious that many in the weight lifting community are willing to jump on isolated small studies with no critical thought as to the validity of the methodology or the soundness of the study. > Then we won't be blind men anymore, will we?

Guest guest Posted February 13, 2008 Report Share Posted February 13, 2008 Any " manipulation " without exogenous use of something is still overruled by the genes of the person and whether they're in the right sport for their own bodies lol. I don't think (and yeah here he is again) Mark Henry had to really think about the sports he's done, the guy's a freak of nature and simply going to succeed as long as he's not running a marathon lol. Perhaps one could maximize one's own releases but the expense and stress of what, constant blood draws? never eating a meal that isn't PERFECT? having all your lifts exactly timed, exactly calculated, and what if you don't make the workout due to well, real life? it's not likely without 24/7 control of an athlete and them having ZERO life outside of your laboratory that you'd succeed? Given they don't know all the puzzle and I think this MAJORLY applies to how women gain muscle without exogenous means....how can you be sure you're getting the maximum out of that athlete anyway! There's still that freak of nature out there who isn't giving a rat about his/her chemistry and mostly eating junk food and can walk in the door and beat even the most carefully groomed athlete! It's like that 6'8 " girl who's clubbing basketballs out of hands in high school right now. why? cause she's 6'8 " with arms like a condor and they aren't. Doesn't matter what she eats, she's 6'8 " . they think she may grow 2 more inches too, lol. Chose the right parents apparently! Unless she decides she wants to arbitrarily be a size four, she'll probably continue to do well in basketball too lol. You could have another girl who isn't 6'8 " , say a still tall 6', and you carefully train her to jump, feed her all the right foods, and watch EVERY moment. Plenty of rest, etc. Plenty of all the right stuff, training, food, etc. She's still not 6'8 " and this girl who is will block her shots, and basically make your girl's life hell lol. Genes can make your efforts succeed or fail, regardless of how you eat or train lol. There are people like the one who was cited with the huge 52 " vertical. He never trained it. He's the freak of nature who is going to drive coaches insane and make people shake their heads...<GRIN>. good topic and again, like i said, it's interesting to those of us dedicate to NOT going the exogenous add on way of life, lifetime drug free is the hardest way to do things <grin>. Harder to dodge stuff that's out there than give in! I am enjoying making the notion that you " lose muscle " in your thirties and onward look ridiculous at age 47....if I can do it as a woman, then men clearly are more likely to not lose their muscle either! without resorting to things exogenous! Nothing but CHALK!

However, one would be naive not to be aware of the substantial industry in anabolic drugs -- mostly hormones or analogues -- in professional sport, many of which do provide a substantial advantage. American baseball is going through a very tough period of soul searching over the use of steroids and related compounds in the sport -- as I'm sure many Supertrainers are aware. Having said that, I do support " natural " athletes and I consider it important that any small advantage that can be got from training in a particular natural way should at least be noted for consideration, especially if a slight change in training modality has no great impact on training logistics. Regarding studies in the sports sciences: Like the nutritional sciences, and unlike many trials in medicine or pharmacology, the sports sciences suffer from small budgets and inadequate team resources. The large, randomised controlled trials that we have come to expect as the gold standard of evidence in the biomedical sciences are, generally, not possible in the sports sciences. We have to glean what we can from much smaller studies and make the best of it. It is true that we cannot attribute much evidence from many of these studies with just a few participants and few controls. Even so, they can contribute to meta analyses over time, and we may gain some understanding of the complex nature of sports physiology and biochemistry by being aware of consistency in findings over time. ================================== Quote Link to comment Share on other sites More sharing options...
