The endocrine system includes all of the glands of the body and the hormones produced by those glands. The glands are controlled directly by stimulation from the nervous system as well as by chemical receptors in the blood and hormones produced by other glands. By regulating the functions of organs in the body, these glands help to maintain the body’s homeostasis. Cellular metabolism, reproduction, sexual development, sugar and mineral homeostasis, heart rate, and digestion are among…..”

This Is What Really Happens In Your Body When You Exercise
There’s so much happening.
PRESENTED BY WALGREENS

“..The human body is an incredible system capable of regulating itself and keeping all of its cells and tissues healthy and in balance. But exercising regularly is critical to maintaining that balance for overall health.
Many people only associate exercise with calories, muscles, and fat, but there is so much more going on in the body. In fact, there are hundreds of hormones, enzymes, proteins, and chemical reactions happening while the body is physically active.
Accounting for every single process that happens during exercise would fill several textbooks, but here’s a brief overview of how the body responds to exercise:..
Brain-derived neurotrophic factor (BDNF) – This is a hormone that interacts with the central nervous system. By tripling BDNF production with exercise, it is possible to improve mood, boost cognitive function, and improve memory. BDNF also contributes to repair of neurons and other housekeeping measures in the brain, which helps prevent neurodegenerative disease…”
1. Antidiuretic Hormone (ADH) “vasopressin”
Hormonal Responses to Acute Exercise humankinetics.com
‘…Posterior Pituitary Hormones
The posterior pituitary lobe stores and secretes ADH and oxytocin, which are transported from the hypothalamus. Little information is available about the effects of exercise on oxytocin. However evidence supports the idea that exercise is a potent stimulus for ADH secretion.
During periods of heavy sweating and intense exercise, ADH works to minimise the extent of water loss from the kidneys, thereby decreasing the risk of severe dehydration. This response helps the body conserve fluids, especially during exercise in the heat, when a person is most at risk for dehydration. By increasing the water permeability of the kidneys’ collecting ducts, ADH facilitates the conservation of water, allowing less water to be excreted in the urine.
With intense muscular work and heavy perspiration, the electrolytes become more concentrated in the blood plasma, which increases the plasma osmolality (the ionic concentration of dissolved substances, such as electrolytes, in the plasma). Additionally, sweating causes water to be drawn out of the blood, resulting in a lower plasma volume. The hypothalamus can sense increased plasma osmolality and lowered plasma volume, and responds by stimulating the posterior pituitary lobe to secrete ADH (see figure 10.6). In contrast, ADH secretion is minimised when fluid intake increases and the blood volume expands, resulting in more dilute urine.

‘…The major form of fat stored by the body. A triglyceride consists of three molecules of fatty acid combined with a molecule of the alcohol glycerol. Triglycerides serve as the backbone of many types of lipids (fats). Triglycerides come from the food we eat as well as from being produced by the body.
Triglyceride levels are influenced by recent fat and alcohol intake, and should be measured after fasting for at least 12 hours. A period of abstinence from alcohol is advised before testing for triglycerides. ..”

8 Hormones Involved in Exercise Pete McCall // Fitness // 8/10/2015 acefitness.org
“…There are three major classifications of hormones: steroid (1), peptide (2) and amines (modified amino acid hormones) (3). Each class of hormones has a unique chemical structure that determines how it interacts with specific receptors. Steroid hormones interact with receptors in the nucleus of a cell, peptide hormones are comprised of amino acids and work with specific receptors sites on the cell membrane, and amines contain nitrogen and influence the sympathetic nervous system.
Hormones can either be anabolic (one), which means they help build new tissue, or catabolic (two) because they play a role in breaking tissue down. The term “anabolic steroids” is often mentioned as a method of cheating used by athletes who want to improve performance; however, anabolic steroids are actually natural chemicals produced by the body that are responsible for promoting tissue growth.
Listed below are some important hormones involved in exercise along with the physiological functions they control.
Insulin (2 FAST)
A peptide hormone produced by the pancreas, insulin regulates carbohydrate and fat metabolism. When blood sugar is elevated, insulin is released to promote the storage and absorption of glycogen and glucose. Insulin helps reduce levels of glucose in the blood by promoting its absorption from the bloodstream to skeletal muscles or fat tissues. It is important to know that insulin can cause fat to be stored in adipose tissue instead of being used to fuel muscle activity. When exercise starts, the sympathetic nervous system suppresses the release of insulin; consequently, it is important to avoid foods with high levels of sugar (including sports drinks) before exercise because it can elevate insulin levels and promote glycogen storage instead of allowing it to be used to fuel physical activity. Wait until the body has started sweating before using any sports drinks or energy gels.
Released in response to low levels of blood sugar, glucagon is produced by the pancreas to stimulate the release of free fatty acids (FFAs) from adipose tissue and increase blood glucose levels, both of which are important for fueling exercise activity. As glycogen levels are depleted during exercise, glucagon releases additional glycogen stored in the liver.
Cortisol (1 & two SLOW)
Cortisol is a catabolic steroid hormone produced by the adrenal gland in response to stress, low blood sugar and exercise. It supports energy metabolism during long periods of exercise by facilitating the breakdown of triglyceride and protein to create the glucose necessary to help fuel exercise. Cortisol is released when the body experiences too much physical stress or is not sufficiently recovered from a previous workout. While cortisol helps promote fat metabolism, exercising for too long can elevate levels of cortisol to catabolize muscle protein for fuel instead of conserving it to be used to repair damaged tissues.
Epinephrine and Norepinephrine (3 FAST)
These amine hormones play an important role in helping the sympathetic nervous system (SNS) produce energy and in regulating the body’s function during cardiorespiratory exercise. Classified as catecholamines, epinephrine and norepinephrine are separate but related hormones. Epinephrine, often referred to as adrenaline because it is produced by the adrenal gland, elevates cardiac output, increases blood sugar (to help fuel exercise), promotes the breakdown of glycogen for energy and supports fat metabolism. Norepinephrine performs a number of the same functions as epinephrine, while also constricting blood vessels in parts of the body not involved in exercise.

“…Despite initiating several different responses, epinephrine’s effects have a collective purpose – to provide energy so that the major muscles of the body can respond to the perceived threat. (4)..”

Testosterone is a steroid hormone produced by the Leydig cells of the testes in males and the ovaries of females, with small amounts produced by the adrenal glands of both genders. Testosterone is responsible for muscle protein resynthesis and the repair of muscle proteins damaged by exercise, and plays a significant role in helping grow skeletal muscle. Testosterone works with specific receptor sights and is produced in response to exercise that damages muscle proteins.
Human Growth Hormone (one & 2 SLOW)
Human growth hormone (HGH) is an anabolic peptide hormone secreted by the anterior pituitary gland that stimulates cellular growth. Like all hormones, HGH works with specific receptor sites and can produce a number of responses, including increasing muscle protein synthesis responsible for muscle growth, increasing bone mineralization, supporting immune system function and promoting lipolysis, or fat metabolism. The body produces HGH during the REM cycles of sleep and is stimulated by high-intensity exercise such as heavy strength training, explosive power training or cardiorespiratory exercise at or above the onset of blood lactate (OBLA, the second ventilatory threshold).
Insulin-like Growth Factor (2 )
Insulin-like growth factor (IGF) has a similar molecular structure to insulin and is stimulated by the same mechanisms that produce HGH. IGF is a peptide hormone produced in the liver and supports the function of HGH to repair protein damaged during exercise, which makes it an important hormone for promoting muscle growth.

Brain-derived Neurotrophic Factor
Brain-derived neurotrophic factor (BDNF) is a neurotransmitter that helps stimulate the production of new cells in the brain. The production of BDNF is closely related to the production of HGH and IGF—the same exercises that elevate levels of those hormones also increase amounts of BDNF. High-intensity exercise can stimulate anabolic hormones for muscle growth while elevating levels of BDNF, which can help improve cognitive function. ..”

Work to Cause Weight-Loss or Weight-Gain
“…The brain requires a constant steady stream of glucose for fuel. If it does not get an adequate supply of carbs, your body uses its available glucose and glycogen stores. Then it turns to fat and muscle mass to supply energy, producing an abnormal metabolic response called ketosis. Ketosis alters the enzymes in fat cells. Ketosis causes muscle mass to be sacrificed and broken back down into amino acids to be converted directly into glucose for the brain. The loss of muscle mass means the loss of fat burning sites. Thus less fat will be burned. It is easy to understand then why 98% of all low-carb and high-pro diets fail. The followers of those methods usually gain back any weight they may have lost and usually more than they lost to begin with.
Glucagon is considered the fat-burning hormone. It is stimulated by the pancreas in response to intake of protein. It’s main job is to maintain stable blood sugar levels in your body. It does this by activating and releasing stored body fat so it can be burned for energy.
THE GOLDEN KEY TO BE RID OF UNWANTED FAT
A moderate amount of carbs, pro, fat helps keep blood sugar balanced. Fat slows down the absorption and digestion of the carbs, providing a steady, ongoing supply of glucose which keeps the fat storage hormone insulin low. Protein in a meal stimulates the release of the fat-burning hormone, glucagon, thereby maximizing your ability to burn stored body fat for energy…”

Hormone Balance and Food Combining: How Proteins, Carbs and Fats Affect the Body’s Behavior bonfirehealth.com
“..Carbs are going to spike our insulin, no matter what; however, we can curb that spike to some degree if we eat some protein and fat along with the carbs. We are in no way recommending a high carb, high processed food diet. It’s important to take it one step further when eating fruits and veggies. It is best when we eat a balanced diet by consuming protein, fat and healthful carbs together at every meal. This is the basis for The Zone Diet prescribed by Dr. Barry Sears. Where we at Bonfire Health differs from Dr. Sears is when it comes to quality of food. He goes into this somewhat, but we want you to focus on eating natural foods (from the earth, not processed), as well as balancing the macronutrient content (protein, carbs and fats).
By eating healthful carbohydrates (fruits and veggies), you will dramatically decrease the insulin released, which will decrease your body’s message to grow and store fat. By going a step further, eating a small portion of lean protein (grass-fed beef, turkey, chicken, etc.) and fats (avocados, nuts, seeds) along with those carbs, you will in fact be balancing your hormones, which will keep you healthy or move you toward health!..”
