Quizplus · Accepted Answer

Endorphins are neurotransmitters that can interact with the receptors in the brain that reduce the perception of pain and create a sense of euphoria. The release of endorphins during exercise, like running a marathon, is known to create a "runner's high." Melatonin is a hormone associated with regulating sleep cycles, dopamine is a neurotransmitter associated with pleasure and reward, and testosterone is a hormone associated with male reproductive functions. None of these are primarily responsible for the pleasurable feeling experienced after running a marathon.
