Exercise, cognitive function, and the brain: Advancing our understanding of complex relationships

In recent years, scientists have shown a growing interest in the relationship between exercise, cognitive function, and the brain. The growing body of evidence supporting positive relationships is evidenced by the first mention of the beneficial effects of exercise on cognitive function appearing in the 9th edition of the American College of Sports Medicine's guidelines published in 2014.1 The strength of this evidence is further confirmed by recommendations relative to the benefits of exercise for cognitive performance and mental health being included in the 2nd edition of the Physical Activity Guidelines for Americans, a landmark policy statement released by the U.S. Department of Health and Human Services.2
