The Evolution of Exercise: Science and Health

Exercise is a conundrum. On the one hand, physical activity is clearly one of the best interventions for preventing physical disease and mental suffering. On the other hand, scientists don't really understand how it works inside the body or what exactly running, jumping, lifting, and squatting do to our tissues and organs. That's finally changing. Euan Ashley, a professor of genomics and cardiovascular medicine and the chair of the Stanford Department of Medicine, is a member of a new research consortium that studies rats and humans to understand the molecular changes induced by exercise. Today we talk about the earliest findings from this new consortium, how exercise might have disparate effects in men versus women, why nature’s most effective cardiovascular intervention also seems to be nature’s most effective mental health intervention, as well as whether it will one day be possible to identify the molecular basis of exercise precisely enough to develop exercise pills that give us the benefits of working out without the sweat.
