Endurance runners’ brains have higher functional connectivity than the brains of less active people, resting state fMRI scans reveal. Researchers compared brain scans of young-adult cross-country runners to young adults who don’t engage in regular physical activity. The runners showed greater functional connectivity, connections between distinct brain regions, within several areas of the brain, including… Read more

The pleasure and reward centers of the brain are activated similarly by dangerous drugs as well as by exercise, which is why therapies to treat drug addiction often include lots of exercise. Scientists say activating these pleasure and reward receptors in the brain could provide the “reward” of dangerous drugs without having to consume those… Read more

The feeling of well-being, freedom and extra energy that runners often experience is not just a matter of endorphins. A study from University of Montreal Hospital Research Centre (CRCHUM) shows that the “runner’s high” phenomenon is also caused by dopamine, an important neurotransmitter for motivation. Lead author Stephanie Fulton, a researcher at the CRCHUM, says… Read more

What gives the world’s most elite sprinters—those that compete in the 100, 200, 400, and 800-meter races—their speed? It’s all in the knees. Researchers were interested to know why Jamaica, with a population smaller than that of Los Angeles, is home to so many of the world’s elite sprinters. Previous research had shown that the… Read more
