High-intensity interval training triggers endorphin release in the brain. Photo: Turku PET Centre

Finnish researchers at the University of Turku have revealed that exercise-induced endorphin release in the brain depends on the intensity of the exercise. Endorphin release induced by exercise may be an important mechanism which affects exercise motivation and maintenance of regular physical activity. The popular high-intensity interval training (HIIT) leads to endorphin release in the brain, which might alleviate the physical and emotional stress caused by the high-intensity exercise. A less demanding, traditional one-hour aerobic exercise does not cause similar endorphin release.

In the study, HIIT significantly increased the release of endorphins and other opioid peptides in the brain area...
