Endorphins and Exercise: Get high naturally
Sports like bodybuilding, powerlifting, contribute to an increased production and release of endorphins. Because they are naturally produced by the body, endorphins are possibly the best (and most legal way) to achieve a natural high.
That's why my clients telling me always that they are feeling great after training.
They always say I always love the feeling when I finish my training and go home. I feel so happy and relaxed. That is endorphin hormone. It does wonders for your mood.
First discovered in 1975, endorphins ("endogenous morphine") is one of several morphine-like substances (opioids) discovered within our brains as recently as thirty years ago. Endorphins are polypeptides containing 30 amino acid units. Opioids are considered stress hormones like corticotrophin, cortisol, and catecholamines (adrenaline, noradrenaline), and are manufactured by the body to reduce stress and relieve pain. Usually produced during periods of extreme stress, endorphins naturally block pain signals produced by the nervous system.
The human body produces at least 20 different endorphins with possible benefits and uses that researchers are investigating. Beta- endorphin appears to be the
endorphin that seems to have the strongest affect on the brain and body during exercise; it is one kind of peptide hormone that is formed mainly by Tyrosine, an amino acid. The molecular structure is very similar to morphine but with different chemical properties.
Endorphins enhance the immune system, they relieve pain, they reduce stress, and postpone the aging process. Scientists also have found that beta-endorphins can activate human NK (Natural Killer) cells and boost the immune system against diseases and kill cancer cells.
HOW DO ENDORPHINS IMPROVE OUR MOOD?
Endorphins are released into the bloodstream by the pituitary
Endorphins enter nociceptive afferents (neurons which carry pain impulses to the brain)
Endorphins then bind to opioid receptors in the neurons (mu, kappa, delta). These receptors are the same as the receptors which drugs like morphine bind to.
Endorphins have an antagonistic effect on the receptors and therefore block the release of neurotransmitter molecules from the nerve terminal.
NO PAIN SIGNALS REACH THE BRAIN!!
The endorphins are therefore said to have an analgaesic effect.
By having this analgaesic effect on the body, endorphin release results in a state of euphoria. As well as reducing pain this also aids in the reduction of stress. Due to these effects, endorphins are known as the body's "natural painkillers". Because they have similar actions to opiate drugs they are also known as the endogenous opioids.
Blood levels of beta-endorphins have been found to increase to as much as five times their resting levels during a prolonged bout of aerobic exercise (over 30mins). This measurement varies from person to person and is affected by how much regular exercise you take part in. Thats why I always feel like I am flying after doing cardio.
