Lactic Acid and Growth Hormone – Low-Intensity Exercise Part III: 180 Degree Health

Low-Intensity Exercise Part III – Lactic Acid and Growth Hormone – 180 Degree Health

Posted


There isn’t a whole lot more that I wanted to say about low-intensity exercise other than for some indivuals, particularly those very sensitive to stress, may fare better keeping intensity level very low.  But I did want to get a few words in about lactic acid and growth hormone, as there is a huge blind infatuation with growth hormone these days.

Growth hormone is far from being worthy of blind worship.  Growth hormone is something that surges when the body is subjected to major stresses.  Two of the most major stresses – fasting and high-intensity exercise at or near one’s maximum heart rate, stimulate the most dramatic increase in growth hormone.  Anorexics, for example, have much higher levels of growth hormone, and are even thought to develop resistance to growth hormone similar to what happens in rats when carbohydrates are removed from the diet.  Growth hormone interacts with other hormones, like IGF-1, and high levels of growth hormone with low levels of IGF-1 are hallmarks of type 2 diabetes.

So growth hormone isn’t necessarily good or bad.  It depends, like most things, on context.  I suspect that very large elevations in growth hormone induced by intense stress may not yield the effect many people think they will get from growth hormone.  Most think of growth hormone as being synonymous with the fountain of youth.  Phil Campbell, one of the leading researchers promoting high-intensity exercise and the Peak 8 or Sprint 8 program he developed, even states that growth hormone should be called “youth hormone.”  Through his growth hormone lens, he even recommends avoiding carbohydrates post-workout despite the giant wealth of research unanimously pointing towards the superiority of big, high-glycemic index carbohydrate supplementation before, during, and immediately after exercise.  Others avoid carbohydrates at night to get a bigger nighttime growth hormone secretion during sleep.

In fact, if you were only trying to maximize growth hormone without any other considerations, the best way to do that would be fasting, carb-restriction, keeping calories low, and regularly performing maximum intensity exercise.  Great for short-term weight loss.  Horrible for long-term health, metabolism, and future body composition.

Like just about anything, there are multiple angles of investigating something.  A myopic view on growth hormone without any regard for other growth factors needed for that equation to be successful, or regard for the possibility of developing growth hormone resistance and having the exact opposite intended result long-term, is a dangerous view.  A great example of this in action is bone loss in anorexics with raised growth hormone levels – ironic considering growth hormone’s direct, active role in growing new bone.

As far as how lactic acid ties into this – lactic acid, presumed by Ray Peat and others to be a harmful byproduct in any context, increases in proportion to the cardiovascular intensity of exercise.  More lactic acid – more growth hormone secretion.  To keep lactic acid production low, heart rate shouldn’t exceed about 70% of one’s estimated maximum heart rate (220 – Your Age).  And lots of low to moderate exercise is even thought to improve lactic acid clearance – probably a good thing.  It might be a little quick to state that “cardio” is dead and that high intensity interval training, circuit training, and other forms of breathless exercise are unquestionably superior in every situation.  That may certainly not be true for you, the individual.

Anyway, not trying to scare anyone away from hard exercise.  Just trying to even the playing field between the modern high-intensity fad and the old, low-intensity fad.  There are pros and cons to each approach, and most probably need a blend of both for health and well-rounded fitness and functionality.
As always, keep an open mind and find what you like, what works, and what increases your metabolism, lowers stress, and enhances your life overall.  These kinds of considerations don’t even seem to enter into scientific debate, which speaks volumes about the limitations of a purely science-guided approach to living a long and prosperous life.

GRHP stands for growth hormone releasing peptide - What Are Peptides & What Do They Do?

What Are Peptides & What Do They Do?

Posted February 20, 2013 in AFL, General Training, Rugby League, Rugby Union by Cameron
Australia’s ‘darkest day in sport’ has centred around the use of ‘peptides’ by our sport stars and legends. The Australian Crime Commission named peptides as one of the notable substances used by professional athletes in their report on ‘Organised Crime and Drugs in Sport’.


But apart from being illegal, what are peptides? And why are our athletes taking them?


Peptide
Most people have heard of proteins – large biological molecules consisting of one or more chains of amino acids. Peptides are simply smaller chains of amino acids, not long enough to be considered a full protein.

Peptides are as numerous as proteins, which are as numerous as grains of sand, so I will focus on those peptides identified in the ACC report as being used within the Australian sporting community known as GHRP-2 and GHRP-6.

GRHP stands for growth hormone releasing peptide, and the numbers correspond to a different structure. The purpose of this small family of peptides is to stimulate the pituitary gland to produce increased natural secretion of human growth hormone through the activation of a specific, G protein-coupled receptor.

It is Growth Hormone secretion that helps the athlete.

Growth Hormone Release

As the name suggests, Growth Hormones stimulate cell regeneration and growth. For the athlete this means increased recovery from damaging matches and training. Increased Growth Hormone will speed up the natural recovery process.

Because the body uses damaging matches and training as a signal for muscle growth (stimulus & response) the increased Growth Hormone being released also has the effect of our body rebuilding our muscles larger and stronger than before.

But it is important that we realise that Growth Hormone is a natural process.

And this raises the interesting question of where we draw the line. Protein powders give athletes taking them a competitive edge over athletes who are not. Just like good training, nutrition, compression wear. But does that make taking protein powders unfair and unsportsmanlike?

An interesting side note, peptides are readily available on the sporting supplement market and are not even very expensive; CJC-1295, GRHP-6

Peak Fitness session increases HGH by of 771 percent! | Phil Campbell Interview

Peak Fitness Exercise Benefits | Phil Campbell Interview

Here's a summary of what a typical Peak Fitness routine might look like:
  1. Warm up for three minutes
  2. Exercise as hard and fast as you can for 30 seconds. You should feel like you couldn't possibly go on another few seconds
  3. Recover for 90 seconds
  4. Repeat the high intensity exercise and recovery 7 more times
As you can see, the entire workout is only 20 minutes. Twenty minutes! That really is a beautiful thing. And within those 20 minutes, 75 percent of that time is warming up, recovering or cooling down. You're really only working out intensely for four minutes. It's hard to believe if you have never done this that you can actually get that much benefit from four minutes of exercise. That's all it is.
Human growth hormone is often referred to as "the fitness hormone." The higher your levels of growth hormone, the healthier and stronger you will be. Once you hit the age of 30, you enter what's called "somatopause," at which point your levels of human HGH begin to drop off quite dramatically. This decline of HGH is part of what drives your aging process, so maintaining your HGH levels gets increasingly important with age.

hgh graph

The longer you can keep your body producing higher levels of HGH, the longer you will likely experience more robust health and strength. Some athletes choose to inject it for this very reason, though it is a banned substance in nearly every professional sport. I do not recommend injecting HGH however, due to the potential side effects, the cost and, more importantly, it is likely to cause more long-term harm than good. Fortunately, your body produces HGH naturally when you exercise your super-fast muscle fibers during vigorous, high-intensity exercise like Peak Fitness.
Phil explains:
"You know, walking is a great thing, but it only works the aerobic process of your heart muscle. It doesn't work the anaerobic process. It only recruits your slow-twitch fibers. So those two other muscle fiber types are meant to be used to exercise is necessary to release growth hormones.
… If we look at the body and say, how do you want us to exercise? When you do this – when you do Sprint 8 – it's almost like the result is screaming this: When you do this, I release this hormone that's so powerful, that if you're an Olympic athlete, your test goes positive for injecting growth hormone. That's how significant Sprint 8 is when you look at growth hormones."
In fact, an eight-week study conducted by Phil and colleagues found that a Peak Fitness session resulted in an average HGH increase of 771 percent! This also translated to increased fat burning among the study participants. Phil states:
"At the end of the eight weeks, results were phenomenal. The average body fat loss was 31 percent. Sprint 8 was designed to replicate the growth hormone production, which in the average case increases 14.4 percent. Basically, Sprint 8 in this one study on middle-aged workers shows that it's twice as effective in body fat loss as injecting growth hormone."

It's hard to believe if you have never done this that you can actually get that much benefit from four minutes of exercise. That's all it is.
Keep in mind that you can use virtually any type of equipment you want for this – an elliptical machine, a treadmill, swimming, even sprinting outdoors (although you will need to do this very carefully to avoid injury) -- as long as you're pushing yourself as hard as you can for 30 seconds. But do be sure to stretch properly and start slowly to avoid injury. Start with two or three repetitions and work your way up, don't expect to do all eight repetitions the first time you try this, especially if you are out of shape.
Phil states:
"There are many different ways you could do Sprint 8. As long as you can get totally exhausted in 30 seconds or less. That's the key. If you can't go longer than 30 seconds -- no matter if you're a professional athlete or just starting -- that means you're doing it correctly. It has to be so intense that after 30 seconds, you're just praying for those last seconds to go by … "
Phil also mentioned that his study showed doing Peak Fitness on an elliptical machine led to a higher release of growth hormone, and he suspects that it is the most challenging type of equipment to use.
One caveat: a treadmill may not be the best choice for Peak Fitness because of the time it takes for the machine to adjust intensities. So instead of the 30-second sprint, by the time the machine calibrates it will only be 20 seconds.
I really discourage people from using the treadmill because I don't believe it is ideal due to lag time to adjust intensity levels and an increased risk of falling off the equipment and injuring yourself. The elliptical is probably close to the best in my opinion. But if you don't have access to a gym or your own equipment, then you can improvise. You can use virtually any type of cardio exercise, as long as you get your knees up and your heart rate up, that's the key.

I would strongly recommend that you invest in a chest strap heart rate monitor to make sure your intensity is on target. If you are able to exceed your calculative maximum heart rate, which is 220 minus your age, by five or 10 beats, then you know you have trained. And you really need to be accurate within a few beats per minute to get the best results. There's a big difference between 166 and 168, but you're not going to be able to calculate that manually. You need an electronic version.

If funds are limited and you can't join the gym or get a piece of equipment, invest in a heart rate monitor. That's going to give you the information you need to make sure you're doing the activity properly.

Human Growth Hormone – The Damage Done By Morons | Romano & Roberts

Anytime I debate the roll of performance enhancing drugs in healthy adult men, especially as we age, a cogent argument will usually try to question my disdain for what I perceive to be the negative effect of media-driven misinformation, politics, and alarmist with agendas.  So what if network and cable news get it wrong? Why should I care if Geraldo “smells steroids?” I should just keep laughing at Don Hooton when his foundation makes ludicrous claims such as Tom Hanks is performing on Broadway “high on steroids” because he took a cortisone shot in his hand. It doesn’t change anything, right? Steroids and growth hormone are illegal.

Well, yes….. and no, and hence this is a complicated issue.  For the sake of this discussion I’m going to use GH as the example.  Steroids would follow a similar yet much more complicated path to your medicine cabinet, however GH represents only a slightly less lurid substance. Remember that it took quite a while for GH to catch up with steroids’ nefarious ranking among the agenda waving alarmists, however, steroids fall under Schedule 3 of the DEA’s list of controlled substances and are treated as a prescription narcotic.  Growth hormone is classified as a prescription medication with specific guidelines for use contained in title 21 of the US Code (USC).  But that doesn’t mean you’ll get a slap on the wrist if you get caught breaking the law controlling it:

Section 303(e)(1) of the Food, Drug & Cosmetic Act (FDCA), Title 21 USC 333(e) (1), “prohibits knowingly distributing, or possessing with the intent to distribute, HGH for any use in humans other than the treatment of a disease or other recognized medical condition, where such use has been authorized by the Secretary of Health and Human Services (HHS) under section 505 of the FDCA (21 U.S.C. 355) and pursuant to the order of a physician. The Secretary of HHS has not authorized, for example, any HGH use for anti-aging, bodybuilding, or athletic enhancement. Thus, distributing, or possessing with the intent to distribute, HGH for these uses or any other unapproved use violates section 303(e)(1) of the FDCA. A violation of section 303(e)(1) carries up to 5 years imprisonment and fines and, if the offense involves an individual under the age of 18 years of age, up to 10 years imprisonment and fines.”

The reason we have such absurd penalties for a naturally occurring hormone is a direct result from pressure exerted by the media, politicians, community groups, and alarmists with agendas who have cast a shadow over an entire industry, erroneously in the name of saving our children.  Because of such penalties, GH is under prescribed and difficult for doctors to implement in therapies that have substantial clinical data to back them.  Here’s a true example that has nothing to do with performance enhancement or anti-aging just to show you how pervasive and how destructive these stupid laws panned out:

Human-Growth-Hormone

A physician had a patient in the hospital who had been on dialysis for several months. After two weeks on GH therapy, he began to make urine again. He was understandably very excited. Even after he was discharged from the hospital, the amount of fluid removed by dialysis continued to be reduced as his kidney function improved. Naturally, he wanted to continue this GH kidney restoration. The attending physician wrote prescriptions for GH along with letters of explanation for why he required it. The insurance company would not pay for it because it was not ‘FDA approved’ for kidney problems, even though it would have saved them tens of thousands of dollars by eliminating the need for dialysis.
To make matters worse, no pharmacy would agree to fill the prescription even though the patient agreed to pay for it himself.  The pharmacies were afraid of being scrutinized by the Feds. The patient has essentially been sentenced by the government to a life on dialysis, thanks to raving morons who think kids are going to jump over a beer keg and mainline GH with dirty needles.

On the other side of the coin, because GH works, people intent on using it will despite the penalties and retarded advisories from the Taylor Hooton Foundation. In fact, quite a few doctors and clinics are moving a bunch of GH.  From 2005 to 2011, inflation-adjusted sales of GH were up 69 percent, according to an Associated Press (AP) analysis of pharmaceutical company data collected by the research firm IMS Health. It’s interesting to note that during the same time frame, sales of the average prescription drug rose just 12 percent.

This increase has been in the wake of years of raids, sports scandals and media attention, yet major drug makers sold a whopping $1.4 billion worth of GH in the U.S. last year. That’s more than industry-wide annual gross sales for penicillin or prescription allergy medicine.

In total eight companies – up from two in 2005 – have been granted permission to market GH by the FDA, although many nutritional companies produce so-called GH releasers or outright scam products claiming to be GH.

Pituitary Growth Hormone by Anabolic Research is a scam
Pituitary Growth Hormone by Anabolic Research is a scam

In contrast, three companies are approved for the diabetes drug insulin.

The No. 1 producer of GH is Roche subsidiary Genentech, that had nearly $400 million in GH sales in the U.S. last year, up an inflation-adjusted 66 percent from 2005. Pfizer and Eli Lilly were second and third with $300 million and $220 million in sales, respectively. Pfizer now gets more revenue from its GH brand, Genotropin, than from Zoloft, its well-known anti-depressant drug.

Endocrinologists estimate there are fewer than 45,000 U.S. patients who might legitimately take GH for its approved use. They would be expected to use roughly 180,000 prescriptions or refills each year, considering typical patients are prescribed GH three months at a time. However, according to IMS Health data, U.S. pharmacies last year supplied almost twice that much GH — 340,000 orders.

And those figures don’t include GH sold directly by doctors without prescriptions at scores of anti-aging medical practices and clinics around the country. Those numbers could only be tallied by drug makers, who have declined to say how many patients they supply and for what conditions.
Regardless, experts agree that the data shows too many sales and too many prescriptions for the number of people known to be under FDA approved treatment. At least half of last year’s sales likely went to patients not legally allowed to get the drug.  And, of course, this does not include illegal black market sales, and illegally compounded GH products.

Children who develop a pituitary deficiency of growth hormone at a young age will never grow normally and are destined to become dwarfs in adulthood if untreated.  Human growth hormone therapy was initially developed to treat those children so they could grow to become normal adults.  Initially, supplies were very limited, expensive and sometimes contaminated because it was harvested from cadavers, and there was not enough growth hormone available to treat all the children who needed it.  With the development of recombinant DNA technology, human growth hormone has become more available and in a very pure, safe, form.

The easy availability of growth hormone now provides a new dimension in health care and preventive medicine, at least it would seem.  However, regardless of any stated or published benefit GH has to offer the aging or athletically challenged, the FDA and the health care industry would rather expose you to almost anything else but growth hormone.  Why?

After you’re done growing, GH must continue to be present in the body (at somewhat lower levels) throughout life to maintain physical and mental health and well-being. Tissue repair, healing, cell replacement, organ integrity, bone strength, brain function, enzyme production, integrity of hair, nails, skin and vital organs all require the ongoing availability of adequate GH.  After age 20, GH production falls progressively and consistently at an average rate of about 14% per decade. By age 60, it is not uncommon to measure a GH loss of 75% or more.  Physical decline with age correlates directly with decreased secretion of GH by the pituitary gland.
how-gh-works
It would stand to reason then that taking GH as we age could stave off the effects of aging.  Not totally nor completely, but the benefits from GH replacement reported in the scientific literature and published in numerous peer reviewed journals over the years do include increased muscle mass, improved physical strength, reduced fatigue, decreased fat (especially abdominal fat), increased bone strength, and revitalization of liver, kidney, spleen, and brain functions.  Skin regains a more youthful appearance with fewer wrinkles and sexual functioning improves.  Cholesterol decreases and cartilage in joints becomes stronger.  Osteoporosis, Parkinson’s disease and Alzheimer’s disease are improved.  Healing is speeded.  And, a markedly better quality of life has also resulted for AIDS patients receiving growth hormone.

So, why can’t we use it?

According to the United States Food and Drug Administration (FDA), FDA-approved GH  (GH that had an acceptable level of negative side effects and did not overly endanger the public) can be legally prescribed for a limited number of conditions including:
  • hormonal deficiency that causes short stature in children
  • long-term treatment of growth failure due to lack of exogenous GH secretion
  • long-term treatment of short stature associated with Turner syndrome
  • adult short bowel syndrome
  • adult deficiency due to rare pituitary tumors or their treatment
  • muscle-wasting disease associated with HIV/AIDS
However, what too many people – including doctors and pharmacists – don’t understand is that, while those are the “approved uses,” it does not mean that GH can’t be prescribed for other therapeutic purposes.  In other words, it doesn’t  mean that if, in the doctor’s opinion, GH would help get a patient off dialysis (as several studies are beginning to demonstrate) he is not allowed to use GH for that patient and that all parties – the doctor, the patient and the pharmacist who supplies it – should go to prison.

On the surface, “FDA approval” is an “approval”, which is not a law, and not even a  “disapproval” of any other use for the same medication. If you tell your teen-age kid they can go out tonight, that approval doesn’t mean they can’t stay home and play video games instead.

To wit, the foreword of the Physician’s Desk Reference, in  accordance with the laws of the states governing the practice of medicine, states:
“The FDA has also recognized that it does not limit the manner in which a physician may use an approved drug. Once a product has been approved for marketing, a physician may choose to prescribe it for uses or in treatment regimens or patient populations that are not included in approved labeling. The FDA also observes that accepted medical practice includes drug use that is not reflected in approved drug labeling.”
The FDA also recognizes that it does not have authority over health care professionals or the practice of medicine.  However, in the case of GH, They do! The following section of the Federal Food Drug and Cosmetic Act provides the restrictions and penalties regarding the distribution of GH:

Title 21: Food and Drugs, Chapter 9–Federal Food, Drug, and Cosmetic Act, Subchapter III: Prohibited Acts and Penalties, Sec. 333. Penalties.
Section (e) lists:

(e) Prohibited distribution of human growth hormone
(1)          Except as provided in paragraph (2), whoever knowingly distributes, or possesses with intent to distribute, human growth hormone for any use in humans other than the treatment of a disease or other recognized medical condition, where such use has been authorized by the Secretary of Health and Human Services under section 355 of this title and pursuant to the order of a physician, is guilty of an offense punishable by not more than 5 years in prison, such fines as are authorized by title 18, or both.
(2)          Whoever commits any offense set forth in paragraph (1) and such offense involves an individual under 18 years of age is punishable by not more than 10 years imprisonment, such fines as are authorized by title 18, or both.
(3)          Any conviction for a violation of paragraphs (1) and (2) of this subsection shall be considered a felony violation of the Controlled Substances Act [21 U.S.C. 801 et seq.] for the purposes of forfeiture under section 413 of such Act [21 U.S.C. 853].
(4)          As used in this subsection the term “human growth hormone” means somatrem, somatropin, or an analogue of either of them.
(5)          The Drug Enforcement Administration is authorized to investigate offenses punishable by this subsection.

The FDA specifically approves the use of GH to treat GH adult deficiency of hypothalamic origin. The following is taken from the FDA approved package insert from Eli Lily’s Humatrope:
“Adult Patients:

Humatrope is indicated for the replacement of endogenous GH in adults with GH deficiency who meet any of the following two criteria:

“Adult-Onset (AO): Patients who have GH deficiency, either alone or associated with multiple hormone deficiencies (hypopituitarism), as a result of pituitary disease, hypothalamic disease, surgery, radiation therapy, or trauma.”

Not surprisingly, aesthetics and anti-aging benefits are not considered “the treatment of a disease or other recognized medical condition, where such use has been authorized by the Secretary of Health and Human Services under section 355 of this title ….” In other words, while GH levels do decrease over time, if the levels are typical for someone in his 50’s, a prescription of GH to a 55 year old might be a problem.

Is that confusing, or what? If the GH deficiency is the result of a disease then the doctor can prescribe it, but if the deficiency is typical then, the way I read the law, it’s making nefarious drug dealers out of doctors.  If the doctor does little more than write a prescription and it is filled by a pharmacy, is the doctor at legal risk? In other words, is the writing of a prescription considered the “distribution” of GH?

Unfortunately, the FDA contends that a licensed physician writing a prescription for GH for an unauthorized use, but not actually physically providing the GH to a patient, would be a violation of 21 USC § 333(e).

The agency interprets “distribution” as used in 21 USC § 333(e) to include the writing of a prescription.  In addition, all federal criminal statutes, including 21 USC § 333(e), are covered by 18 USC § 2:

“(a) Whoever commits an offense against the United States or aids, abets, counsels, commands, induces or procures its commission, is punishable as a principal.

  (b) Whoever willfully causes an act to be done which if directly performed by him or another would be an offense against the United States, is punishable as a principal. ”

So, what we have is a confounded set of laws dictated by people with little or no medical or scientific training, who have never laid eyes on a patient, who invariably have some vested financial interest – as with insurance companies or with a political agenda – are deciding the treatment for sick people and making criminals out of the doctors who treat them.  And guess what? The insurance industry is not liable for any medical problems resulting from their denial. The doctor will probably be sued instead.

So, the next time I rage about idiots like Don Hooton and the other hysteria mongers who are using steroids and GH as fodder for their soap box folly, I’m saying so because of the damage they do.  These morons are not saving a single kid from anything.  All they have done and continue to do is vilify legitimate drugs with legitimate uses and ultimately cause them to be denied to people who can genuinely derive benefit from them.  Like I always say, you want to save the children? Then get rid of alcohol and cigarettes….

What is growth hormone?

Growth hormone (GH), also known as somatotropin, is an anabolic hormone made and secreted by the pituitary gland.

GH is a large polypeptide thought to encourage growth indirectly by stimulating the release of growth factors from the liver and muscle (e.g., IGF-1).

These growth factors create the cascade of events typically associated with higher GH concentrations. GH is released in response to growth hormone releasing hormone (GHRH) produced by the hypothalamus.

Why is growth hormone so important?

GH helps bone, muscle, and other tissues grow.

In the muscle, GH stimulates protein synthesis as well as fat metabolism. GH recruits fatty acids from storage and tells the body to use fatty acids for energy.

Interestingly, as GH limits the storage of fats and mobilizes them for energy, blood sugar levels concurrently increase. In this way, GH “spares” carbohydrates from breakdown, and the level of sugar in the blood increases. This is why long-term GH replacement may predispose one to insulin resistance.

The effects of GH on fat mobilization can begin at 20 minutes after release and last up to 3 hours.
You may wonder why intense exercise is so effective at helping you lose fat, even though it doesn’t seem like a few sets of heavy squats would burn that many calories. Many researchers credit the concomitant appearance of high concentrations of plasma fatty acids and GH that follow intense training.

GH also:
  • Decreases blood sugar utilization
  • Decreases glycogen synthesis
  • Increases amino acid transport into cells and protein synthesis
  • Increases fat breakdown and utilization
  • Increases collagen synthesis and cartilage growth
  • Increases retention of nitrogen, sodium, potassium, and phosphorus
  • Increases kidney flow and filtration
  • Enhances immune function

What you should know

The reference range for healthy GH levels is 0.06 – 8.0 ng/mL.

When someone is GH deficient, GH replacement seems to be safe and may even promote health – at least with long-term monitoring by a physician. There seems to be a mild risk of insulin resistance.

Sleep and GH

Sleep is associated with the release of hormones such as GH. This may be why sleep helps us repair and recover. Sleep associated GH secretion has also been linked to the nocturnal rise in fatty acid release.

As one ages, there is a decrease in sleep duration and GH secretion. Sleep deprivation in young individuals reduces GH secretion and may contribute to premature development of the metabolic syndrome. As you can see in the diagram below, GH secretion peaks late at night.

Exercise and GH

The secretion of GH during and after exercise is proportional to intensity. The tougher and harder the exercise, the more GH is released. Think sprints instead of long slow distance runs.

Increases in GH secretion are related to increases in acids, by-products of high intensity exercise. Also, catecholamines may stimulate GH secretion. Rest periods of 60 seconds or less can help stimulate GH release.

GH slowly rises during an intense workout, but it actually peaks only when the workout is over. Thus, the peak GH release concurs with the maximal fatty acid release from fat tissue. Exercise also appears to increase the amplitude and number of GH pulses during the day.

Reducing calorie intake doesn’t seem to create a GH deficit. Data indicate that cutting calorie intake by 25% doesn’t significantly reduce GH levels, and people who exercise with the right type of training may actually see GH increase.

Summary and recommendations

To ensure healthy growth hormone levels:
  • Exercise intensely, using many muscle groups
  • Exercise with multiple sets, short rest periods (<60 seconds) and heavy weight (~10 rep max)
  • Ensure adequate carbohydrate and protein consumption before and after workouts
  • Avoid/limit alcohol consumption
  • Get 7-9 hours of sleep each night
  • Maintain a lean/healthy body composition

Growth hormone

Growth hormone, also known as the somatotropic hormone or somatotropin, is produced by the somatotrophs. It is an important hormone for growth and development.

Functions of Growth Hormone

Effects on Growth:
Growth hormone effects growth by:
a. Increasing the number of cells.
b. Increasing the size of the cells.
c. Increasing the differentiation of cells
Metabolic Effects
Growth hormone has metabolic effects on
a. Proteins
Growth hormone decreases the utilization of proteins in the body by:
1. Increase in protein deposition in the cells
2. Increase in DNA transcription
3. Increase in RNA translation
4. Increase in amino acid transport
5. Decrease in protein catabolism
b. Carbohydrates
A decrease carbohydrate utilization is observed along with a decrease in glucose uptake by the tissues, accompanied by increased glucose production by the liver. An increase in insulin production is also observed, but it is unable to mediate its effects of decreasing glucose levels in blood (this is attributed to the increased levels of free fatty acids, which hinder the effects of insulin). Thus growth hormone is a diabetogenic hormone producing pituitary diabetes (due to overproduction of glucose and decreased utilization).
c. Fats
Growth hormone increases the utilization of fats and increases fat mobilization. It causes an increase in the levels of free fatty acids in the plasma. The levels of acetyl Co-A (produced from the free fatty acids) also rise in the body, thus fats are used for providing energy to a greater extent, while carbohydrates are spared. Thus, under the influence of growth hormone, an increase in lean body mass is observed. Increased production of acetyl Co-A also lead to increased formation of ketone bodies, thus causing ketosis.
Effects on bones
Growth hormone causes:
a. increased deposition of proteins by chondrocytes and osteoblasts
b. increased reproduction of chondrocytes and osteoblasts
c. conversion of chondrocytes into osteocytes
Mechanisms of bone growth
There are two ways in which bones grow:
a. Longitudinal growth
Longitudinal growth involves the increase in bone length which occurs at the epiphyseal plates. The chondrocytes undergo mitosis and there is deposition of new cartilage. Ossification of new cartilage results in the formation of new bone. There is, thus, elongation of shaft in longitudinal growth.
b. Horizontal growth
The horizontal growth involves the increase in bone thickness. The osteoblasts deposit new bone while the osteoclasts remove the old bone. The rate of deposition of bone is greater than the rate of resorption. There is ,thus, increase in thickness of the shaft.

Somatomedins:

Somatomedins are small proteins synthesized in liver under the influence of growth hormone. These are also known as Insulin-like growth factor (IGF). They increase all aspects of bone growth. Somatomedins have longer half life than growth hormone. There are four major somatomedins, but the most important is the somatomedin C (IGF-I).
African pygmies have a congenital inability to synthesize somatomedin C. Their plasma growth hormone levels are normal or high, but they remain small statured. The Levi-Lorain dwarves have the same problems.

Regulation of GH

Hypothalamus releases growth hormone releasing hormone (GHRH) which increases the production of growth hormone. It also releases growth hormone inhibitory hormone (GHIH), which inhibits the production of growth hormone.
The GHRH acts through the cAMP dependent 2nd messenger system.Short term influences are mediated through the calcium influx while the long term effects through the transcription and new hormone synthesis.

Growth Hormone and Aging

Growth hormone is also known as anti-aging hormone as is evident from the growth hormone levels during different periods of life:
a. 5-20 yrs —- 6 ng/ml
b. 20-40 yrs — 3 ng/ml
c. 40-60 yrs — 1.6 ng/ml

Anti aging actions of GH

Growth horomone has anti aging actions due to the fact that it increases the deposition of proteins, at the same time decreasing the deposition of fats. Person has a feeling of increased energy.
