Running would give the same feeling as when cannabis is the surprising conclusion of a new study.
” Euphoria “, or” ecstasy “of runneur, the” runner’s high “in English, is now common analogy between practice (moderate to heavy) of the running and euphoric effect created by a drug, and in this case cannabis.
A new study from the journal Eos reveals that this state of happiness that most runners feel after a longer or shorter output is actually not created by endorphins as was thought until now. In reality, it is quite surprising that “ecstasy” comes from the release in the body of a high dose of endocannabinoids, of euphoric substances that the human body secretes himself and have the same effect as marijuana.
Until now, scientists assumed that this state of well-being came endorphins, known as the name of sour endorphins. These substances are produced by the pituitary gland and hypothalamus in case of intensive efforts and long lasting. They resemble the opioid analgesic capacity and to provide a well-being. But apparently those endorphins would not reach through the barrier blood to disseminate this there planing sensation.
Researchers at the University of Hamburg and Heidelberg have therefore wondered how this state of euphoria was provoked in the runner. He left to run a group of 5 mice in a wheel. They then discovered a higher dose of endocannabinoids in the brain compared to those who did not run. These substances secreted by their body in turn influenced the neurotransmitter anandamide told that plays an important role in memory and for pain and depression.
Groups of mice were then subjected to tests tolerance to pain and distress, ran in the dark. Mice that had run for 5 hours seemed less stressed and seemed better tolerate pain. The researchers then blocked the release of endocannabinoids in the brain of mice, they are then shown as anxious and felt the same pain as those who were not running.
Researchers also compared a group of mice with another sample which had no high dose of endorphins released into their bodies. Their conclusion: both groups had the same behavior, a sign that endorphins did not render a group of mice better than the other.
