Endorphins: what are they? How are they measured? What is their role in exercise?

Journal article

A generalized knowledge of opiates has been available for centuries, but it was not until 1975, following the isolation of the first endogenous opioids, that it was appreciated that their analgesic properties were mediated via specific receptors. Three general classes of opioids are now recognized: the endorphins, the enkephalins, and the dynorphins. Assaying of the endogenous opioid peptides has never been simple, and now radioimmunoassay has replaced the earlier bioassays. When coupled with...
